(LEI) designed the electrical and street lighting portion of the Little Italy Streetlight Improvement as a subconsultant to Project Design Consultants (PDC). The project included both the re-lamping existing streetlights and installing new streetlights in the Little Italy area and was designed according to San Diego City standards. The project required coordination with San Diego Gas and Electric (SDG&E), the Centre City Development Corporation (CCDC) and the City of San Diego Street lighting Department. LEI designed the power system for the streetlights with a maximum voltage drop of 5%, by performing voltage drop calculations, from the point of connection to the farthest light fixture. An additional task of the project removed 5 KV series city street lighting circuits. Several scenarios were outlined, depending on the existing conditions encountered. For City blocks without existing street lights, for street lights to be added, a branch circuit was extended from the point of connection (POC) to each light fixture. These branch circuits were sized to accommodate future street light installation. Where existing POCs did not have an electrical panel, LEI installed an outdoor rated pedestal with an electrical panel. Where existing POCs had an electrical panel, it was evaluated for the possibility of connection. Where additional streetlights were added to a city block with existing streetlights, the branch feeders were extended to the new streetlights from the existing streetlights. To increase economic savings, reduce waste and avoid disturbing historic buildings, unnecessary material and trenching was avoided. The power design used existing conduit wherever feasible and code-compliant. Wiring was replaced unless installed within the last 10 years. Lights for each block were fed from a POC on that block. Where possible, uniformity on the location of the POC was done; typically located in the southwest corner of the block. https://www.lopezengineering.com/water daily 0.75 2020-11-03 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1601314646239-AAT65D2N2ZY82BADG349/Collier+Tunnel++.png WATER https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1601322804848-8UMQK9HV2GYUV6A63AXN/North+City+Water+Reclamation+Plant+Wastewater+Upgrade+Project+.png WATER https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600794314027-LC2RPKFGCTG3JNP24KYI/Gaviota+Water+and+Wastewater+Upgrade+Design+Project3.jpg WATER https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1603237206841-1IL6LKBPNJDP7EAFDOS3/69th%C2%A0%26+Mohawk+Pump+Station_1.png WATER https://www.lopezengineering.com/schools daily 0.75 2020-11-03 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600795438273-2AIROLZD942CM38E1WWD/Thoreau.jpg SCHOOLS https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600987936071-Y7K71PZJJQB3CK1XCBXY/UCSD.png SCHOOLS University Campus Energy Storage 2.5 MVA https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1601322144503-BS8I0Z2LAHPRARIW9C3Q/New-Mexico-Highlands-University2.jpg SCHOOLS https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600795468235-MC8L156QHELMQ8MJSHUV/Wide+Ruins+School.jpg SCHOOLS https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600795114479-XPIO43IR653IYZ75SM0I/Schools-Bosque-Farms-Elementary.jpg SCHOOLS https://www.lopezengineering.com/design-emergency-generator daily 0.75 2020-09-22 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600805656942-2UE6KWSRHYDYYX4TPDZ4/Emergency-Seal-Beach-Weapons-Station-Transformer.png Design- HVAC Renovation - HVAC Renovation/Retrofit of DOE Facility Client: Department of Energy – National Nuclear Security Administration Center Location: Albuquerque, NM Lopez Engineering, Inc.

LEI designed the lighting, power, and special systems for this project, which is currently out to bid, and will provide construction administration support. This 8th floor project, 19,700 ft2, which is related to the 9th floor Cardiac Unit project also being designed by LEI, increases the number of patient beds, increases number and area of nurse stations as well as remodeling them, increases number and area of utility rooms, adds locker rooms, and brings the electrical and mechanical systems up to code for two floors. In order to create room for these remodeling requirements, this project eliminated offices, exam rooms, waiting areas, and exercise rooms. LEI separated the emergency electrical system into the 3 branches: Life Safety, Critical, and Equipment. Egress lighting, fire alarm panel, fire dampers, and medical gas alarm panels were connected to the life safety branch. Patient bed lighting, nurse station lighting, select patient bed receptacles, select nurse station receptacles, and VAV controls were connected to the critical branch. Remaining loads were connected to normal power panels. HVAC loads, VAV box controls, were connected to the Critical Branch because they were small. Project replaced all lighting and labeled receptacle and toggle switch stainless steel covers with branch circuit. Obsolete normal power distribution panels, 480Y/277V, 3P, 4W were replaced with new panels. The fire alarm system was replaced with an addressable system including chimes, strobes, pullstations, smoke detectors, and panels. The old Fischer Berkeley Nurse Call System was replaced with a Hill-Rom Nurse Call system using Cat 5 plenum rated cable and cable trays to interconnect system components New telephone and network data lines, 4 pair telephone plenum rated cable, were extended to patient rooms from the telephone closet using cable trays and conduit. Telemetry antennas were placed on the ceiling every 30’ along the corridors and connected a central station provided by the hospital using Cat 5 plenum rated cable in cable trays. https://www.lopezengineering.com/water-department-of-energy-water daily 0.75 2020-09-23 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600883104612-0KDXKI8VX102XTEI2X12/21st-Street-Pump-Station.jpg Water-Energy Saving - Energy Saving Options 21st Street Sewer Pump Station Client: City of Del Mar Location: Del Mar, CA Lopez Engineering, Inc.

(LEI) provided engineering services for the 180,000 GSF (est) Otowi Revitalization – HVAC Upgrades Project for Los Alamos National Laboratory (LANL) in Los Alamos, New Mexico. Serving as the basis for this project is LEI’s LANL Otowi Building Systems Upgrade (FEMP Funded) that was awarded the Department of Energy’s Prestigious 2004 Energy Management Achievement Award. LEI’s initial project was an energy project feasibility study that identified all energy efficiency opportunity based upon a ten-year payback threshold. The estimated cost for this project was $500,000 and the projected annual savings was $165,000. The study’s scope included evaluation of lighting systems and lighting control, evaluation of occupancy loads, assessment of HVAC efficiency and control, and evaluation of existing solar hot water and cooling tower systems. The building analysis utilized PowerDOE software as a basis for the building model. PowerDOE results were base-lined by comparing to monthly meter consumption and continuous electrical load recordings over time to establish the consumption profile. The Energy Retrofit Design Scope consisted of refurbishment of the solar hot water system, retrofit of the cooling tower, installation of plate and frame heat exchanger for free cooling installation cooling, installation of state-of-the-art DDC energy management system with VFDs, replacement of the inefficient air filter system with a high efficiency system, upgrade of lighting controls, occupancy sensors, and switches for control of nonessential electrical load in offices when unoccupied. Drawings included equipment schedules, floor plans, enlarged floor plans and detail of both electrical and mechanical systems. Extensive control diagrams of the energy management system included sophisticated sequences of operation and a comprehensive points list. The feasibility study was used as a basis to secure grant funding. LEI’s current Otowi Revitalization Project-HVAC Upgrades Project is divided into two phases. The first phase identifies a preferred alternative for the desired improvements and develops a design description and scope of work for the project. LEI is designing upgrades and improvements for the Otowi Building that improve building infrastructure services and building comfort while extending building service life by 20 to 30 years. LEI, with its sub-consultant Burns and Roe, performed a comprehensive evaluation of the existing central station and other HVAC system components, including but not limited to Air Handling Units (AHUs), Heating Hot Water units (HHW), Variable Air Volume units (VAVs), pumps, HVAC controls, and the electrical system to meet current codes and standards and to provide a modern HVAC System able to meet the needs of the building occupants. The evaluation included a walkdown and evaluation of the existing HVAC and Electrical Distribution systems, load calculations and recommended design and construction alternatives for the building infrastructure upgrade. By evaluating the controls, LEI determined whether to modify or replace the systems entirely. LEI is also modifying the lightning protection system as required to protect new roof-mounted HVAC units. To select the best upgrade alternatives, LEI developed and supervised a joint selection process of a preferred engineering solution that included input from the design team and from the client, Los Alamos National Laboratory (LANL). Criteria used for decision making included: general information, scope of study, evaluation criteria, list of evaluated alternative, and recommended design solution. Once the evaluation was completed and LANL selected the upgrade options to be pursued, the LEI team began design of the building modifications necessary to implement the agreed upon upgrades. This design effort, which is ongoing, will include primarily HVAC, controls, and electrical system upgrades. However, it will also include architectural, structural, and Fire Protection as required. Currently this project has completed the 65% design phase with 95% design effort soon beginning. The final product of this first Task was a 65% engineering Title II design submittal, which was completed by the end of Fiscal Year 2010. The objective of the second phase is to complete the engineering design. https://www.lopezengineering.com/govt-nctd-electric-panel-schedule daily 0.75 2020-11-03 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1602521685825-MR42KABWSO4V1IZXMBMS/4.+Healthcare_Option+1.jpg Health Care-Cochiti Wellness Center - Cochiti Wellness Center Client: ArSed Engineering Location: Cochiti, NM The Cochiti Wellness Center, a medical / dental clinic building, is located in Cochiti, New Mexico.

The total square footage for the building is 3,880 square feet. Lopez Engineering, Inc. was sub-contracted by ArSed Engineering Group, a mechanical engineering firm, to provide electrical design services that were required for permit and construction documents. The project was under a strict budget which Lopez Engineering efficiently met. Electrical service to the building was provided from a new pad mounted transformer with underground feeders to a main 208Y/120V 3-phase electrical distribution panelboard, with utility meter and main building disconnect on the building exterior. This panel provided power to all electrical loads within the building as well as parking lot and building exterior lighting. Interior lighting was designed to meet IESNA design recommendations with T8 fluorescent fixtures with control from dual toggle switches in each space. https://www.lopezengineering.com/water-north-city-water-reclamation daily 0.75 2020-11-03 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600884981511-Z9YUQ5FETSKFDTHLWPBN/Schools-Bosque-Farms-Elementary.jpg Schools-Electrical Engineering - Electrical Engineering Services for Bosque Farms Elementary School Client: Dekker/Perich/Sabatini Location: Bosque Farms, NM Lopez Engineering, Inc. subcontractor to Dekker/Perich/Sabatini provided electrical engineering services for the Bosque Farms Elementary School located in Bosque Farms, New Mexico. LEI’s initial project was an electrical condition assessment survey for the existing Elementary School. Electrical systems evaluated included the electrical infrastructure/power distribution, lighting systems, telephone/data systems, Fire Alarm system and Public Address System. LEI provided a written evaluation with cost estimate for systems upgrades/renovations. The assessment included an On-Site Survey of the entire facility’s mechanical, plumbing and electrical systems with particular emphasis on the condition of the systems, evaluation of the system operation and their ability to properly serve the facility (and future expansions), identification of general problem areas with potential causes, evaluation of remaining life, identification of parts availability and maintainability, evaluation of current code violations, identification of systems requiring immediate repair, identification of items needing upgrades/replacement. LEI’s more recent Bosque Farm Project was to renovate two of the existing wings, approximately 21,00 GSF (1936 and 1988 buildings) and build out approximately 27,600 GSF of new building space, as well as the demolition of the existing 1965 building. The project included new electrical infrastructure design, utility analysis of the electrical, telecommunication, and cable TV services, as well as Public Address System, Fire Alarm, Telephone/Data, and Security System. LEI conducted field investigation for the locations of the utility services and existing electrical infrastructure, attended meetings, and corresponded with utility companies for point of connections. The project is broken down into four stages: Schematic Design, Design Development, Construction, and Bid/Construction Administration. As part of Schematic Design LEI provided site demolition drawings for the renovated electrical service to the site, design of the electrical systems including equipment types and methods for providing site utilities, site lighting, building lighting, electrical and special systems. LEI will also provide a schematic design for the utility points of connection including electrical and telephone. Based on schematic design, LEI provided design development documents to include: lighting calculations, floor plans, cost estimate, and electrical site plans for transformer location, entrance lighting, exterior building lighting, and parking lot lighting. Following design development, complete construction documents were prepared to include: specifications, voltage drop calculations for site lighting, panelboard schedule, and demolition plans for electrical infrastructure and equipment in the 1936, 1988 and 1965 buildings. Currently the project is in the final stage, Bid & Award/Construction Administration. LEI has provided bid support including preparation of addenda and bid evaluation. Construction Administration will consist of RFI responses, submittal review, Construction Inspection, and preparation of as-built drawings. https://www.lopezengineering.com/government daily 0.75 2020-11-04 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1603231004970-2WKQYFO9D6DZUVIE1D3A/Govt_TA-03+TA-50+Parking+Structures.png GOVERNMENT https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1602520792453-PB82G569G6GDJHM1QJFJ/5.+Jicarilla+Administrative+Center+Building.jpg GOVERNMENT https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1601313653277-J3VQEMTGOE5PX8W4I20C/NCTD.png GOVERNMENT https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1602523544975-ZDEAL2SEFMUJCW91V0ND/MCAS+II.jpg GOVERNMENT https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1602524278545-LHL359M7S61L8AISHFS9/Otowi1.jpg GOVERNMENT https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600729357435-G4H2LY5WJTKRJ9KQ58X0/TA+50.jpg GOVERNMENT https://www.lopezengineering.com/healthcare daily 0.75 2020-11-03 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1602521656280-77M249QBNB9Q0SJGOX6O/4.+Healthcare_Option+1.jpg HEALTHCARE PROJECTS https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600729747054-TOELFT1YM4D9B5WAZSXE/VA-Long-Beach-Hospital-and-Campus.jpg HEALTHCARE PROJECTS https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600729791131-I2YV8YDZL57E0C9W3WZ0/St.-Vincent-Hospital.jpg HEALTHCARE PROJECTS https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600729525548-C31C0SFC16BF008V7VKX/Healthcare-Lovelace-Medical-Center-w-Trees.jpg HEALTHCARE PROJECTS https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600729829443-QV9JEODYYM0L11XTYR3F/UNMH-Chiller-Expansion.jpg HEALTHCARE PROJECTS https://www.lopezengineering.com/govt-san-diego-international-airport daily 0.75 2020-11-03 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600813923020-1SJE6H0FL0GS804G7P2G/TA+50.jpg Govt-TA 50, Building 1 - TA 50, Building 1 Client: Los Alamos National Laboratory Location: Los Alamos, New Mexico Lopez Engineering, Inc (LEI) was subcontracted by ARES Corporation to partially upgrade the electrical distribution system of Building 1 at Technical Area (TA) 50 at Los Alamos National Laboratories in Los Alamos, New Mexico. The existing electrical equipment was past its useful life and it was becoming difficult to obtain replacement parts for the equipment. Electrical equipment replaced include a 300 kVA dry-type transformer, a switchgear, six Motor Control Centers (MCCs), ten lighting panelboards, two 45 kVA dry-type transformers, and two power conditioners. The distribution equipment served various lighting panelboards, motor loads, lighting branch circuits, and power branch circuits. Through the electrical upgrade, two of the MCCs were eliminated in favor of a switchboard type construction. This approach was chosen since the existing MCCs did not serve any motor loads, only lighting panels. One of the project goals was to limit any outages to the industrial motor loads in the building since Building 1 is a critical facility for TA 50. A detailed Sequence of Construction was developed so that new electrical equipment was installed before the existing equipment was removed. New parallel feeders were installed so that the new equipment was operational and the existing loads could be transferred to the new equipment with a nominal electrical outage. New feeders to lighting panelboards were installed, rather than splicing and extending the existing feeders. New branch circuits were installed up to the first device in the run. Once the existing loads had been transferred to the new electrical equipment, the existing electrical equipment was removed. The space previously occupied by the old electrical equipment was then used to install new equipment for the next stage of the upgrade. https://www.lopezengineering.com/photovoltaic-10000-sf-serpa-building daily 0.75 2020-11-03 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600817536521-JQWF6SU12JDB6J1IGX8H/asu.jpg Photovoltaic-Arizona State University Parking - Arizona State University Parking Structures 1 & 5 - 1 MW & 750 KW Client: ViaSol Energy Solutions Location: Phoenix, Arizona Lopez Engineering, Inc.

SDGE is currently seeking LEED rating for schools, with the PV system being one of the major credits. https://www.lopezengineering.com/power-systems-inspection-evaluation daily 0.75 2020-11-03 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1603233608436-3SENWDRCKJKYSK0YMMF7/NASNI+CADSMCP+Upgrade.png Power Systems-NASNI CADSMCP Upgrade - Upgrade to the Compressed Air Distribution System Plants at Naval Base Coronado (NBC); Naval Air Station North Island (NASNI) Client: SDG&E Location: Coronado, CA Lopez Engineering, Inc. (LEI) is providing professional engineering services to complete the upgrades of the Compressed Air Distribution System Plants at two buildings at Naval Base Coronado (NBC), Naval Air Station North Island (NASNI), Coronado, CA. The project involves installation of New Controls and Reduction of Operating Pressure for the Compressed Air Distribution System (CADS). LEI’s previous work effort for this project accounted for 35% design of the total upgrades needed. Among the systems to be upgraded in/on buildings are controls (some limited in our efforts), sensors, cooling towers, pumps, piping, valves, interior and exterior lighting, a modular building including floor preparation, and a solar photovoltaic system (to the 35% only). It is expected that after project completion, NAVFAC SW Utilities Mechanical Division, will be able to control the compressed air supply based on demand, saving energy and operation and maintenance by reducing the compressors system running time. Other benefits from this project will be equipment infrastructure improvement, bring all systems to today’s codes and standards and the useful life extension of both plants for at least another 10 years. https://www.lopezengineering.com/judicial-gsa-dennis-chavez-federal-building daily 0.75 2020-11-03 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600887372832-J4WU02N9D0RVPS3X2A4D/navajo3.png Judicial-Navajo Nation Justice - Navajo Nation Justice Centers Client: Dyron Murphy Architects Location: Tuba City, Arizona and Crownpoint, New Mexico Lopez Engineering, Inc.

Emergency Generator Installation for Five Buildings Client: Seal Beach Naval Weapons Station Location: Seal Beach, CA Lopez Engineering was engaged to provide standby engine generators and automatic transfer switches (ATS) for five buildings at Seal Beach Naval Weapons Station. Each had its own loading requirements as well as overall requirements from the base and its environmental department. Initially loads were measured during field work that were substantially less than the transformer kVA ratings. The base electricians tested for the maximum loading for each building and added priorities that would also be required at that location. This, in turn, answered questions concerning the loading of the existing transformers. Four of the five buildings had existing transformers whose secondary was to be used to insert the standby engine generator system. Work on this project was restricted to ‘off-hours’ and was location specific. The building usage also gave restrictions on the length of time the power could be out without generator backup while construction was underway. Instrumentation and controls for the engine generators and automatic transfer switches consists of standard equipment items (controls and instrumentation) contained in the engine generator and automatic transfer switches. They are designed and installed to automatically start the diesel engine generator upon loss of power and transfer building load to the diesel engine generator once it came up to frequency and voltage. Additionally, these pre-packaged controls have a standard feature that allows someone to exercise (start) the engine generator, run it under load for a period of time, run it through a cool down cycle, and then turn if off. These are standard off the shelf items ready for purchase. https://www.lopezengineering.com/water-nasni-sewer-pump daily 0.75 2020-09-23 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600883432184-J1W10WH39Z24OYAULKIV/Water-Vallecitos-9.jpg Water- Vallecitos 9 - Vallecitos 9 Flow Control Facility Client: San Diego County Water Authority Location: San Marcos, CA Lopez Engineering, Inc.

The Lopez Engineering team designed the electrical system upgrade for many of the North County Transit District (NCTD) sites in San Diego County, CA. This electrical upgrade project resulted from the arc flash study prepared by Lopez Engineering, Inc. (LEI) for NCTD. During that study, LEI identified electrical equipment that needed to be upgraded due its condition and/or its age being beyond the expected life of that equipment. Sites that were upgraded included Oceanside Transit Center, Old Town Station, Santa Fe Station, Palomar College Site, 417 Autumn Dr site, Encinitas Station, Solana Beach Station, Vista Transit Center, Carlsbad Village Station, Poinsettia Station, East Division and Sprinter Operations Center, Escondido Transit Center, San Marcos Civic Center, NCTD Administration Bldg., NCTD West Ops, Stuart Mesa - Camp Pendleton. Additional sites were investigated for the potential need to upgrade them, which included: Palomar College Station, Buena Creek Station, Camp Sprinter, Sprinter Operations Center, and San Luis Rey Station. Additional field work was conducted at these 21 sites beyond what was performed for the Arc Flash Study. Electrical equipment to be upgraded include: switchboards, Motor Controls Centers, Distribution Panel boards, Panel boards, Dry Type Transformers, and feeders. Some of the equipment will be replaced while other equipment will need to be relocated in order to comply with the California Electrical Code (CEC) clearance requirements. Electrical outages will be required at all locations with some of those requiring weekend outages, while others such as the NCTD Headquarters requiring that continual power be provided during the upgrade. All locations will need to have two-week warnings prior to the required outages. Design will include combining some equipment, increasing capacity of other equipment, decreasing the effects of excessive voltage drop at certain existing facilities, and relocating other equipment for better access. The electrical system upgrade consists of over 200 panelboards, switchboards, motor control centers, disconnect switches, and dry type transformers. Construction documents currently being developed include: drawings (single line diagrams – demo and revised, site plans, floor plans, elevations, enlarged floor plans, details, and schedules), specifications, cost estimate, and sequence of construction. https://www.lopezengineering.com/health-care-university-of-new-mexico daily 0.75 2020-11-03 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600817244033-327W4FMGF91VKVYNORIM/Photovol-SERPA.jpg Photovoltaic-10,000 SF SERPA Building - 10,000 SF SERPA Building Client: Dekker/Perich/Sabatini Location: Espanola, NM Lopez Engineering, Inc. (LEI), subcontractor to Dekker/Perich/Sabatini, provided electrical design services for the 10,000 GSF (est) Solar Engineering Park and Academy (SERPA) for Northern New Mexico College, located in Espanola, NM, which will be LEED Silver Certified. The building is a new high-tech academic study, research laboratory, testing, and evaluation facility designed to reflect and advance the “solar culture” of the region. LEI performed field investigation, coordinated with the electric, telephone, and cable TV utilities, prepared basis of design documents, calculations, drawings, and specifications, and developed cost estimates. Calculations include load, lighting, short circuit, voltage drop, overcurrent coordination, IECC, and potential Photovoltaic (PV) energy generation. The main architectural goal for the building, led by Dekker/Perich/Sabatini, is to create a welcoming and modern exterior that expresses the building use for engineering and the function of the building systems such as expression of the structural system and integrated solar collecting strategies. This building will provide the infrastructure to train and develop NNM technicians and engineers to work in the energy efficiency and renewable energy field. A portion of the site has been set aside for experimenting with PV and wind systems. Classrooms have been dedicated to teaching energy audit techniques. Central monitoring systems will be installed in this building to enable students to learn about PV systems as well as other renewable energy technology both building mounted and located on the site. SERPA was designed with a building envelope that emphasizes energy performance while meeting the client’s desire to express both technology and local material traditions. These envelope strategies, along with the mechanical and lighting strategies, are expected to reduce the building’s energy costs by 35%. https://www.lopezengineering.com/pump-control-city-of-san-diego daily 0.75 2020-09-22 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600818722962-C54A1C1T5ULS9X46IZE2/Otowi.jpg Pump Control- Otowi Building - Otowi Building Revitalization - HVAC Upgrades Project Client: Los Alamos National Laboratory Location: Los Alamos, NM Lopez Engineering, Inc. (LEI) provided engineering services for the 180,000 GSF (est) Otowi Revitalization – HVAC Upgrades Project for Los Alamos National Laboratory (LANL) in Los Alamos, New Mexico. Serving as the basis for this project is LEI’s LANL Otowi Building Systems Upgrade (FEMP Funded) that was awarded the Department of Energy’s Prestigious 2004 Energy Management Achievement Award. LEI’s initial project was an energy project feasibility study that identified all energy efficiency opportunity based upon a ten-year payback threshold. The estimated cost for this project was $500,000 and the projected annual savings was $165,000. The study’s scope included evaluation of lighting systems and lighting control, evaluation of occupancy loads, assessment of HVAC efficiency and control, and evaluation of existing solar hot water and cooling tower systems. The building analysis utilized PowerDOE software as a basis for the building model. PowerDOE results were base-lined by comparing to monthly meter consumption and continuous electrical load recordings over time to establish the consumption profile. The Energy Retrofit Design Scope consisted of refurbishment of the solar hot water system, retrofit of the cooling tower, installation of plate and frame heat exchanger for free cooling installation cooling, installation of state-of-the-art DDC energy management system with VFDs, replacement of the inefficient air filter system with a high efficiency system, upgrade of lighting controls, occupancy sensors, and switches for control of nonessential electrical load in offices when unoccupied. Drawings included equipment schedules, floor plans, enlarged floor plans and detail of both electrical and mechanical systems. Extensive control diagrams of the energy management system included sophisticated sequences of operation and a comprehensive points list. The feasibility study was used as a basis to secure grant funding. LEI’s current Otowi Revitalization Project-HVAC Upgrades Project is divided into two phases. The first phase identifies a preferred alternative for the desired improvements and develops a design description and scope of work for the project. LEI is designing upgrades and improvements for the Otowi Building that improve building infrastructure services and building comfort while extending building service life by 20 to 30 years. LEI, with its sub-consultant Burns and Roe, performed a comprehensive evaluation of the existing central station and other HVAC system components, including but not limited to Air Handling Units (AHUs), Heating Hot Water units (HHW), Variable Air Volume units (VAVs), pumps, HVAC controls, and the electrical system to meet current codes and standards and to provide a modern HVAC System able to meet the needs of the building occupants. The evaluation included a walkdown and evaluation of the existing HVAC and Electrical Distribution systems, load calculations and recommended design and construction alternatives for the building infrastructure upgrade. By evaluating the controls, LEI determined whether to modify or replace the systems entirely. LEI is also modifying the lightning protection system as required to protect new roof-mounted HVAC units. To select the best upgrade alternatives, LEI developed and supervised a joint selection process of a preferred engineering solution that included input from the design team and from the client, Los Alamos National Laboratory (LANL). Criteria used for decision making included: general information, scope of study, evaluation criteria, list of evaluated alternative, and recommended design solution. Once the evaluation was completed and LANL selected the upgrade options to be pursued, the LEI team began design of the building modifications necessary to implement the agreed upon upgrades. This design effort, which is ongoing, will include primarily HVAC, controls, and electrical system upgrades. However, it will also include architectural, structural, and Fire Protection as required. Currently this project has completed the 65% design phase with 95% design effort soon beginning. The final product of this first Task was a 65% engineering Title II design submittal, which was completed by the end of Fiscal Year 2010. The objective of the second phase is to complete the engineering design. https://www.lopezengineering.com/arc-flash daily 0.75 2020-11-03 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600887963506-09SPDLVLXJTTONY55L1S/Arc+Flash.png Arc Flash-Short Circuit Coordination Study - Short Circuit Coordination Study for VA Palo Alto Health Care System Client: VA Palo Alto HCS Location: Palo Alto, CA Key personnel for this project included John Lopez, PE, Neil Sherer, EIT, Donald Crawford, and Wesley Breckenridge. They performed an Arc Flash Study at the VA Palo Alto Health Care System in Palo Alto, CA. This study analyzed and evaluated the 12.47 kV electrical distribution system for the VA Palo Alto Health Care System facilities. Existing drawings for the electrical system were reviewed; electrical system components were visited and observed by an electrical subcontractor (Global Power, Inc.) with equipment and training to open and observe 15 kV rated equipment. VA maintenance personnel familiar with the electrical system were interviewed along with SKM software used to perform short circuit and arc flash calculations. Global Power, Inc, accompanied by VA Electricians, surveyed the existing 12 kV distribution system. They gathered the existing electrical drawings, opened all transformers and gathered nameplate data for all electrical equipment, including individual relays, feeder conductor sizes and circuit lengths, as well as photographed existing equipment. LEI used this gathered field data to developed single line diagrams and modeled the system in SKM. Analysis of single line diagrams for hazards was performed and a short circuit study was prepared. Arc Flash labels were prepared and delivered to Global Power to install on electrical equipment. A follow up overcurrent coordination study was also performed to coordinate the substation main circuit breaker and feeder breaker relay settings with the City of Palo Alto substation circuit breaker relay settings. https://www.lopezengineering.com/power-systems daily 0.75 2020-11-03 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1603233730846-D4UHFKLUXIIHGOM5FWNN/UNM+Main+Gear+Replacement+PH+IV%C2%A0.png POWER SYSTEMS https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1603232861662-Y81HFK0MU0MF9WMALSHS/Power_ABQ+Metals+Shredder+Building.png POWER SYSTEMS https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1603233417182-QBF9PNUMDOBJML5RUQFD/NASNI+CADSMCP+Upgrade.png POWER SYSTEMS https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1603233344742-27ZIIKY9WP3C9JJW6AZX/Power_MCAS+Yuma_Repair+Electrical+Distribution.png POWER SYSTEMS https://www.lopezengineering.com/water-energy-saving daily 0.75 2020-09-23 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600883264857-2UOD2Z9LNHYO52KM7GF1/NASNI-Sewer-Pump-Station-356.jpg Water-NASNI Sewer Pump - NASNI Sewer Pump Station 356 Condition Assessment Survey Client: SDG&E Location: Coronado, CA Lopez Engineering, Inc.

It examines the existing water usage for the Department of Energy (DOE) – Albuquerque Operations Office (AL) site including both buildings and the landscaping. Current practices and water conservation plans are included with the water conservation effects captured where possible. Buildings investigated include: 380, 381, 381 Conference, 381/382 Interconnect, 382, 383, 384, 385, 386, 387, 388, 389, 390, 391, 392, 393, 397, 398, Modular Buildings, South Campus, Child Care Center, and Energy Training Complex. Department of Energy (DOE) – Albuquerque Operations Office site is comprised primarily of offices which provide DOE Central Administration for the U.S. weapons programs. Buildings in the site total approximately 500,000 square feet. Several buildings are newer vintage. Much of the area is within World War II vintage barracks buildings now used for offices. Heating at the time of the study was provided by Steam from Sandia National Laboratories (SNL) via Kirtland Air Force Base’s steam distribution system. Hence water and chemical usage was not investigated because it pertained to SNL. Steam heating has since been replaced with distributed pulse boilers based on another feasibility study performed by Lopez Engineering, Inc., which, though pertinent to this project, is not listed due to a maximum of ten project descriptions. Project: replaces existing older style plumbing fixtures within rest rooms with ultra low flush toilets, waterless urinals, and reduced flow faucets with proximity sensors and automatically controlled mixing valves; replaces the remaining manually controlled sprinkler system with timers and reduced flow sprinkler heads to match changes recently implemented by DOE-AL maintenance contractor; and connects all landscape water system timers to a signal which varies their daily watering period based on weather. Water savings for implementing these changes were estimated on a building by building basis. Spreadsheets listed savings with all the pertinent data pertaining to the calculations. All recently completed and projected landscaping projects by DOE-AL maintenance contractor to reduce water consumption. Though a decrease in domestic hot water heating would be realized, this related energy cost was not calculated.

(LEI) to upgrade the underground telephone and signal manhole system at the 10th Ave Marine Terminal. The new system was to be installed throughout the existing manhole layout before the existing system was removed to keep the clients up and running with no down time. The base provided site plans including the Telephone Manhole (TMH) locations, then creation of as-builts of the existing TMH system began. Preliminary field work supplied the routing of the cables and single line drawings of the system were laid out. From these, the phases of demolition and installation were laid out to keep the port phone system up and running. The project was temporarily put on hold due to unforeseen changes in facilities planning and modifications to the scope of work. LEI resumed design and project schedule and the project is due to go to bid at the beginning of March 2011. Removal and installation began from the Main Point of Entry (MPOE) at 980 Gull Street and terminated at the MPOE at each building. After the telephone system was converted from the old to new, the demolition of the old system took place. Field inspections showed abandoned cables that required removal to make room before the new system was installed. The inspections also showed existing aluminum conduits that required replacement by concrete encased duct banks. The project cost was estimated to be $800,000. https://www.lopezengineering.com/photovoltaic-houweling-nurseries daily 0.75 2020-11-03 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600817972953-LWFHPDHAZ8MQV1KH34L8/photo-department-of-transportation.jpg Photovoltaic-Navajo Department - Navajo Department of Transportation Client: Dyron Murphy Architects Location: Albuquerque, New Mexico Lopez Engineering, Inc.

LEI designed roof-mounted, grid-tied, PV systems for 31 separate campus sites, which included elementary schools, middle schools, high schools, and district operation buildings. These PV systems ranged in size from 29 kW to 366 kW. The combined PV system size for the entire district was 3.3 MW. Each PV system was comprised of 230 W photovoltaic panels with a micro-inverter installed at each panel. This eliminated the need for DC wiring and large, stand-alone inverters that would need to be individually sized for each campus and building. The PV systems could also easily be expanded to include additional PV panels without replacing existing inverters. The PV systems were designed per CEC, SDUSD, and San Diego Gas and Electric (SDGE) standards. Electrical Points of Connection were evaluated to determine if the existing electrical distribution system had capacity to accommodate the additional current that would be introduced by the new PV systems. Depending on the system size, the PV systems were either connected to the building distribution panel (load side connection), or were connected to the campus distribution switchboard upstream of the electrical meter (line side connection). Electrical meters were installed for the PV systems to measure system output for both the Electrical Utility company (SDGE) as well as meters for the Owner (SDUSD) to track PV power production. LEI provided Construction Administration to attend construction coordination meetings, review electrical submittals, answer Requests for Information (RFIs), perform periodic Site Observations and prepared As-Built Record Drawings. https://www.lopezengineering.com/water-gaviotawater daily 0.75 2020-11-03 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600884315064-PW4GADH4QLGJ81LA9MF9/North+City+Water+Reclamation+Plant+Wastewater+Upgrade+Project+.png Water- North City Water Reclamation - North City Water Reclamation Plant Wastewater Upgrade Project Client: City of San Diego via CH2M Location: San Diego, CA Lopez Engineering, Inc.

LEI designed the electrical systems for the North City Water Reclamation Wastewater Upgrade project, which is a major part of the Clean Water Project being implemented by the City of San Diego. This project replaced, modified, and added a significant part of the wastewater system. Due to its very large size, the project was subdivided into four packages, 1. Equalization, 2 Balance of Plant, 3. North City Pure Water Facility (NCPWF) Inlet Pump Station, and 4. Initial Site Package. LEI was initially responsible for all the electrical design for packages 1 through 3 and was responsible for coordinating with SDG&E for Package 4 and developed the initial single line diagram and substation layout for a new POC. As the project evolved, CH2M electrical engineers took over some of the facilities. For the co-generation, LEI helped coordinate meetings with SDG&E and equipment manufacturer representatives while CH2M took the lead for the electrical design for this project’s portion. While the NCPWR Influent Pump Station and two new electrical rooms were new facilities with lighting and special systems requirements, the electrical systems represented the vast majority of LEI’s design effort. https://www.lopezengineering.com/judicial-albuquerque-metro-court daily 0.75 2020-11-03 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600887111653-K4SIVQ4LJ1CDQHGAIJER/Dennis-Chavez-Federal-Building.jpg Judicial-GSA Dennis Chavez Federal Building - GSA Dennis Chavez Federal Building Client: Hart & Majewski Design Group Location: Albuquerque, NM Lopez Engineering, Inc.

(LEI), retained by Helio Power, designed an award-winning Photovoltaic system for Fallbrook Public Utility District. This 60 kW Photovoltaic System project provides renewable generation at the Fallbrook Public Utility District’s (FPUD) headquarters together with sophisticated metering and displays. These allow FPUD customers to see an operational system and become educated about photovoltaic systems and their benefits. It reduces current energy usage by approximately a third primarily during daily peak periods, which is the most expensive energy to generate. Two existing open carport roofs provided the module mounting area while the inverters and electrical panel boards were mounted to an interior wall. Maintenance requirements are substantially reduced from those required in most electrical generation plants, transportation costs are also reduced. System design utilizes four hundred and fifty eight (458) photovoltaic modules, each rated for 148 watts at full power or 64 kW. For safety at the photovoltaic modules, safety switches rated for photovoltaic systems each connect to sixteen photovoltaic modules. Additional safety switches, located near the inverters, enable each inverter to be safely disconnected from the solar photovoltaic system. Each inverter feeds an electrical panelboard’s branch circuit breaker. Two electrical panelboards are required to collect the 16 photovoltaic module groups’ output with the smaller capacity panelboard feeding the larger capacity panelboard. This, in turn, feeds back to the main switchgear via a metered utility visible disconnect with disconnects on both sides of the meter. Underground, concrete encased ductbanks connect photovoltaic modules on the farther roof with their respective inverters and the larger electrical panelboard with the utility visible disconnect. Remaining connections are in surface mounted rigid conduit. https://www.lopezengineering.com/commercial-public-safety-building daily 0.75 2020-11-03 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600803884124-3226V7Y79338Z415YTXG/Santa-Ana-Multipurpose-Building.jpg Commercial-Santa Ana Multi - Santa Ana Multi-Purpose Building Client: Santa Ana Pueblo Location: Santa Ana, New Mexico Lopez Engineering, Inc.

(LEI) provided Electrical design support to Travers Mechanical Services to connect a new chiller and cooling tower to the University of New Mexico Hospital (UNMH) electrical system. According to the Contracting Officer, LEI was the first consulting firm to continually record existing electrical equipment prior to connecting new load to it. LEI recorded current for 72-hours for normal and emergency power equipment branch switchboards, panelboards, and motor control centers in order to determine existing spare capacity. These recordings revealed an existing normal power switchboard and MCC to be overloaded. These recordings also revealed the emergency power equipment branch to have insufficient spare capacity to serve this additional load when using the “N-1” criteria. As a result of the recording results, chiller service design required connecting to a spare 15 kV outdoor switchgear compartment. From there, a 15 kV feeder extended to a new 1000 kVA, pad-mounted, oil filled, transformer, 12.47 kV-480Y/277V, 3 Ø, 4 W. A feeder was extended from the transformer secondary to a new electrical switchboard, 1600 A, 480Y/277V, 3 Ø, 4 W. This new switchboard then fed a new 1200 A, 480Y/277V, 3 Ø, 4 W motor control center (MCC). In order to alleviate the overloaded condition of the normal power switchboard, some load was transferred from it to the new switchboard. LEI fed the new chiller, cooling tower, chilled water, and condenser water pumps from this new MCC. This new chiller served all hospital chilled water loads as an integrated part of the chilled water system. In order to alleviate the overloaded condition of the normal power switchboard, some load was transferred from it to the new switchboard. LEI fed the new chiller, cooling tower, chilled water, and condenser water pumps from this new MCC. This new chiller served all hospital chilled water loads as an integrated part of the chilled water system. Our approach corrected existing overloaded panels and MCCs and provided for limited future growth in UNMH’s central plant. We used our most cost effective resources to perform the study and design. When doing fieldwork, we spend additional time prior to the visit in planning all the information that must be obtained and during the visit to make sure that we obtain all the required information. LEI prepared its proposal based on connecting to existing electrical equipment. However, it was necessary to design new electrical services in order to feed the chiller and related equipment. LEI did the design for the original fee even though there was substantial additional design work required by having to design new electrical service both for the chiller and the auxiliary equipment. https://www.lopezengineering.com/pump-control-ta-46-154-hvac-upgrade daily 0.75 2020-09-22 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600819042070-PV9KG1NVZB5KFU667WOX/Tucumcari.jpg Pump Control-Tucumcari Ethanol Plant - Tucumcari Ethanol Plant Client: Advanced Process Solutions Location: Tucumcari, NM Lopez Engineering, Inc. (LEI), subcontractor to Advanced Process Solutions, designed the electrical infrastructure to serve the electrical needs of the 35,000 GSF (est) Tucumcari Ethanol Plant, located in Tucumcari, New Mexico. The client was United Stainless Process Technologies. LEI also reviewed the process controls including P&ID drawings, verified their accuracy, or modified where necessary and stamped and signed for them. Our design enabled the existing plant, which had been shut down, to become operational and expand its output from 3,000,000 gallons per day to 10,000,000 gallons per day. LEI worked closely with Advanced Process Solutions to develop a detailed understanding of their processes, electrical needs and controls, including detailed sequences of operation and P&ID drawings. LEI became familiar with their P&ID standards. LEI reviewed the process piping drawings developed by Advanced Process Solutions and developed a comprehensive understanding of the piping documents. After drawings were reviewed, verified that they met all project process piping needs, and were deemed compliant with applicable codes, Lopez Engineering stamped and signed them for submission to the State of New Mexico for permitting. LEI prepared calculations, including lighting, voltage drop, short circuit and overcurrent coordination studies, and prepared the electrical contract documents for the ethanol plant. Documents provided included demolition and revised electrical drawings. Drawings consisted of legend, abbreviations, general notes, 1-line diagrams – electrical, site plans, floor plans-electrical, floor plans-lighting, and floor plans-special systems, enlarged partial site plans, enlarged partial floor plans, schedules, details, control diagrams and specifications. LEI’s electrical system design included a new 480 V, 3Ø, 3W, 3200 A, service entrance to existing industrial facility, which was comprised of a utility pad mounted transformer, a meter enclosure, and service entrance conductors. LEI upgraded (3) existing Motor Control Centers to add motors ranging from 1 horsepower to 200 horsepower. New starters were provided, along with overcurrent protection, and local start/stop control switches were added for the motor loads. New transformers and panelboards were provided to correct NEC violations. LEI further provided analysis of the industrial facility to determine NEC hazardous classifications for the various areas. https://www.lopezengineering.com/schools-1 daily 0.75 2020-11-03 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600796039004-0QA724RKYNJ1LHTYKR35/navajo1-2.jpg JUDICIAL/DETENTION https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1603232383029-28NYZ9WG7SUE8IX9ZH4J/Judicial_El+Cajon+Public+Safety+Center.png JUDICIAL/DETENTION https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600796000326-UKJ7N93U5W0VIJ3WT1CI/ABQ.jpg JUDICIAL/DETENTION https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600796018884-R1TWA4OY1GYZ1QHMNHQ3/Dennis-Chavez-Federal-Building2.jpg JUDICIAL/DETENTION https://www.lopezengineering.com/govt-mcas-basewide daily 0.75 2020-09-22 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600813380099-WR5W3FYZCBCANDIT0XBI/department-of-transportation.jpg Govt-Navajo Department of Transportation - Navajo Department of Transportation Client: Dyron Murphy Architects Location: Albuquerque, New Mexico Lopez Engineering, Inc. (LEI), subcontractor to Dyron Murphy Architects, provided electrical design services for a 52,000 GSF (est) office building for 100 employees of the Navajo Department of Transportation, which is 2-story commercial construction, fully sprinkled, and LEED GOLD Certified. LEI performed field verification, coordinated with the electrical, telephone, and cable TV utilities, prepared basis of design documents, calculations, drawings and specifications, and developed cost estimates. The schematic design portion has been completed, and we are currently preparing construction documents. During bidding and construction phases LEI will assist and provide construction administration services. The electrical systems include power, lighting, 90 kW Photovoltaic (PV) system, Fire Alarm, telephone, and cable TV. Project planning and implementation have used regular design charrets to conceptualize LEED points to be pursued. The Electrical Systems for the building were designed with the intent to be LEED Gold certified. To help achieve this rating, the electrical systems design incorporates the following LEED Credits: Light Pollution reduction (1) LEED point, optimize energy performance, on-site renewable energy (3) LEED points, and controllability of systems- lighting (1) LEED point. https://www.lopezengineering.com/health-care-electrical-system-study daily 0.75 2020-11-03 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600816591811-VJELYHHQ2666F49U5764/St.-Vincent-Hospital.jpg Health Care-St. Vincent Hospital - St. Vincent Hospital Emergency Department Expansion Client: The Design Group Location: Santa Fe, NM The Design Group engaged Lopez Engineering, Inc. (LEI) to inspect and expand the electrical systems for the Emergency Department expansion at St. Vincent Hospital in Santa Fe, New Mexico. The 20,000 square foot Emergency Department (E.D.) expansion included trauma rooms, isolation rooms, mental health, pediatric and other treatment rooms, nurse stations, reception areas, waiting areas, staff lounges, and staff locker rooms. Our management approach involved reviewing the Scope of Work, inspecting the site, conceptualizing what information was needed to prepare the design, identify the stakeholders, identify the electrical engineers that would be doing the reviewing, identifying the maintenance personnel, and identifying anyone who would in any way be connected with the project, and scheduling our resources. Next, we conceptualized the approach and communicated it to the PM and others interested. This approach included continually recording power to potential points of connection and inspecting electrical equipment points of connection. Old, outdated electrical equipment led to our recommendation to provide new equipment connected elsewhere and eventually eliminate load on the existing gear until it is unloaded and can be replaced. Scheduling requires that our design is complete in sufficient time to allow for a quality review prior to each submittal. Good communication and professionalism serve as core values upon which to base our Management Approach. Our approach enabled the contractor to meet the project schedule by providing timely documents even though some Scope of Work items were clearly outside the LEI Scope of Work. It facilitated the contractor’s work, which is an advantage to the owner. Though the engine generator expansion and normal power infrastructure upgrade project was being handled by another engineering firm, LEI provided the design for the new normal and emergency power switchboards because the other firm did not establish these POCs. This was done without requesting additional services even though substantial additional design work was required. As with every project, we used our most cost effective resources to perform the field investigation and design. When doing fieldwork, we spent additional time prior to the visit in planning all required information gathering to make sure that we are efficient. Our electrical P.E. reviewed, participated in, and provided professional oversight for all design facets. However, his time was scheduled such that other engineers and designers could perform as much of the work as possible in their areas of competence. LEI field verified as-built drawings, performed a thorough site investigation to update the 1line diagrams and located electrical equipment on floor plans. After relocating E.D. functions to the new E.D., the existing E.D. remodel was designed. The existing E.D. remodel connected egress lighting, fire alarm panel, and medical gas alarm panels to the Life Safety Branch; connected patient bed lighting, nurse station lighting, selected patient bed receptacles, selected nurse station receptacles, and VAV controls to the Critical Branch. The rooftop air handling unit and stand-alone chiller were connected to the Equipment Branch. Remaining loads connect to the Normal Power branch. In addition to the 480Y/277V, 3 Ø, 4 W panels connected to the various electrical service branches, isolation panels together with low impedance wiring, short branch circuits, and two maximum receptacles per branch circuit were added to the Trauma Rooms. Fire alarm system installation used an addressable system to integrate into the hospital fire alarm system. Installation included chimes, strobes, horns, pullstations, smoke detectors, and panel-addressable system. Rough-ins consisting of conduit, junction boxes, and pull string were provided for Nurse Call, Telephone, Network Data, and Card Readers systems. Remote parking lot lighting, entry area lighting, bus stop lighting, a lighted hospital sign, and a bus stop security camera to facilitate customer service were also included. While recordings for all existing switchboard potential points of connection were performed and indicated that their capacity would accommodate the increased electrical load, switchboard age, condition, and extreme difficulty in finding parts precluded connecting the E.D. expansion or even the existing E.D. area remodel project to the existing incoming switchboards. New switchboards were provided for normal power, Emergency Critical, and Emergency Equipment branches. Project phasing kept the existing E.D. operational until the E.D. expansion was completed. After expansion areas became operational, the existing E.D. was remodeled. https://www.lopezengineering.com/water-vallecitos-9 daily 0.75 2020-11-03 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1600884054458-E0CD90DLWMPC3ADWM2HW/Gaviota+Water+and+Wastewater+Upgrade+Design+Project3.jpg Water- Gaviota Water - Gaviota Water and Wastewater Upgrade Design Project Client: Caltrans via North Star Location: Highway 101 North of Santa Barbara, CA Lopez Engineering, Inc.

The existing substation was owned and operated by Public Service Company of New Mexico (PNM) but was converted to primary metering where PNM meters the customer load at 46 kV and Albuquerque Metal Recycling takes service at 46 kV and is responsible for the electrical system from that point. The design included coordination with PNM regarding location of the new substation and complying with applicable PNM standards for a customer owned substation. The new substation design included connection from the load side of PNM’s 46kV lattice mounted disconnect switch to a new customer owned lattice, disconnect switch, and fuses. From there, it was connected to a new 10MVA, 46kV to 13.8kV transformer, with secondary protection provided by a 15kV Vacuum Breaker. These items were specified for owner purchase and contractor installation by Lopez Engineering, Inc. A medium voltage feeder from the substation serves two 13.8 kV to 575V transformers, which provide power to (2)2500 HP motors through a pair of 3200 amp AC to DC converters. It also serves a third transformer, 13.8kV to 480Y/277 Volt, 3 phase, 4 wire, for service to a 3000 amp switchboard. This switchboard feeds two motor control centers, lighting loads, and miscellaneous power panelboards. The (2) MCCs feed a combined total of 65 additional process motors. All building HVAC and lighting are fed from a 277/480V panel in the Shredder Building. All shredder equipment power and data connection requirements were coordinated with the equipment supplier.

OBR is subcontracted to RBF Consulting, A Baker Company with whom LEI has worked throughout this project. This pump station facility piping is designed to handle a minimum of 18.03 MGD (12,521 gpm). It also entails 3,400' of new pipeline and replacement of Cast iron pipelines totaling 3,960'. The project includes offsite 16-inch water pipeline adjacent to the new Water Branch Building at Chollas operations yard. It contains six pumps of which three (3) are 125 HP powered by Soft Starts and three (3) 75 HP pumps powered by VFDs. An extensive SCADA communicates via telemetry to the City of San Diego’s water control facility. This pump station is designed for remote operation by the City of San Diego. LEI performed Site Investigations of recently completed pump stations and conducted interviews with City of San Diego personnel in order to determine the City’s preferences for control sequences and facility documentation. Coordination with San Diego Gas and Electric (SDG&E) was required to extend a new electrical service entrance to the proposed pump station location. The electrical distribution system incorporated an existing 500 kW diesel generator provided by the City. Since the total pump station electrical load exceeded the capacity of the generator, LEI performed a load analysis to determine the maximum operating capacity of the pump station while on emergency power. The pump station control sequence was written to incorporate this design constraint. The Construction Drawing set included Site Plans, Lighting, Power, and Special Plans (Security, Telephone, Fire Alarm, I&C), Single-Line Diagrams, Ladder Diagrams, Schedules (Panelboard, Conduit, Box, Equipment, etc.), Process and Instrumentation Diagrams (P&ID), Sequence of Operations, Equipment Elevations and Control Panel layouts. Calculations included Service Entrance Load, Lighting, Title 24, Short Circuit, and Arc Flash. LEI also completed Construction Specification Sections and a Construction Cost Estimate. LEI provided Construction Administration to attend construction coordination meetings, review electrical submittals, answer Requests for Information (RFIs), and perform periodic Site Observations. https://www.lopezengineering.com/special10th-ave daily 0.75 2020-11-03 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1603238100619-RY2MG5H6DUHETC1N81AY/10th+Ave+Marine+Terminal+.png Special-SDUPD 10th Ave - SDUPD - 10th Ave Marine Terminal Infrastructure Upgrade Telephone & Fire Alarm Client: Unified Port of San Diego Location: San Diego, CA The Unified Port of San Diego engaged Lopez Engineering, Inc. (LEI) to upgrade the underground telephone and signal manhole system at 10th Ave Marine Terminal. The new system was installed throughout the existing manhole layout before the existing system was removed to keep the clients up and running with no down time for the telephone system. The Fire Alarm system was able to have down time with around the clock watch of affected areas. Communication with 10th Avenue Marine Terminal Tenants was critical both during design and construction as were accurate Cost Estimates based on current market prices, which were submitted at each deliverable: 30%, 60%, 90%, and Final. After construction was complete LEI participated with the Unified Port of San Diego and the Contractor to commission the Fire Alarm and Telephone system. The Unified Port of San Diego provided site plans including the Telephone Manhole (TMH) locations. These were used as a base for LEI to create accurate as-builts of the existing TMH system for both Telephone and Fire Alarm systems. Field work served as a basis for cable routing and single line drawings of the Telephone and Fire Alarm systems. These, in turn, enabled the development of demolition and installation phasing to keep the telephone system functional. The Main Point of Entry (MPOE) at 980 Gull Street, previously designed by LEI, was the telephone project’s beginning point. Newly created building Telephone Points of Entry served as the Telephone Projects end points. After the telephone system was converted from the old to new, the demolition of the old system took place. Prior to installing new cable, abandoned cables identified during the field investigation were removed to free up conduit spaces allowing installation of the new telephone system. The removed Fire Alarm (FA) system utilized the telephone cable system whereas the new FA System used fiber optic cable between buildings containing stand-alone Fire Alarm Control Panels (FACP) that communicate with each other and with the main FACP at the main Guard Shack. The FA System in each building was replaced with an addressable FA system utilizing addressable FA devices. Existing aluminum conduits were replaced with concrete encased duct banks. https://www.lopezengineering.com/special-sdupd-10th-ave daily 0.75 2020-11-03 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1603238306146-99DQ6XR4YDTBVHMUUFQ4/SDUPD+-+National+City+Marine+Terminal+Fire+Alarm.png Special-SDUPD - National City Marine Terminal - SDUPD - National City Marine Terminal Fire Alarm System Upgrade Client: Unified Port of San Diego Location: San Diego, CA The Unified Port of San Diego engaged Lopez Engineering, Inc.

The new FA system was coordinated with the National City Fire Marshall (NCFM) incorporating signaling systems requested by the NCFM. The Fire Alarm system was able to have down time with around the clock watch of affected areas. Communication with National City Marine Terminal Tenants was critical both during design and construction as were accurate as-built drawings. Extensive field work was conducted to accurately identify the existing FA systems. As a part of design, the final drawings were used to perform an extensive walk through to assure constructability. After construction was complete, LEI participated with the Unified Port of San Diego and the Contractor to commission the Fire Alarm system. The Unified Port of San Diego provided site plans including underground conduit routing. These were used as a base for LEI to create accurate as-builts of the existing FA system. Field work served as a basis for cable routing and single line drawings of the Fire Alarm systems. These, in turn, enabled the development of demolition and installation drawings. Existing FA systems in each building and throughout the site were removed and a new addressable FA system installed with several FACPs installed in buildings for protection from the weather. The removed Fire Alarm (FA) system utilized the telephone cable system whereas the new FA System used fiber optic cable looped between the buildings containing stand-alone Fire Alarm Control Panels (FACP) that communicate with each other and with the main FACP at the main Guard Shack. This allows any one cable to be cut and the FA system to continue working with each FACP continually communicating with the other FACPs. The FA System in each building was replaced with an addressable FA system utilizing addressable FA devices. https://www.lopezengineering.com/emergency daily 0.75 2020-11-03 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1603229173635-INVD3AQXY4OUIWMHM63Z/Screen+Shot+2020-10-20+at+2.26.01+PM.png Govt-HEAF Exhaust System - HEAF Fume Hood Exhaust System Modernization Client: Lawrence Livermore National Laboratory (LLNL) Location: Livermore, CA LEI was contracted by Bath Group to provide Electrical Engineering services for the HEAF Fume Hood Exhaust System Modernization at Lawrence Livermore National Laboratory (LLNL).

Building Electrical scope of work included replacing service entrance equipment, refeeding existing HVAC units from new service entrance equipment, replacing existing standby engine generators and automatic transfer switches, and correct existing electrical deficiencies for impacted equipment. LEI deliverables included Gathering and Reviewing As-Built Record Drawings, Site Investigations, Construction Drawings, Specifications, Load Calculations, Generator Sizing Calculations, Construction Cost Estimates, Bid Assistance, and Construction Administration. Due to the total estimated project cost and available funding, the project scope was divided into phases based on building priority and cost. During the Design Phase, LEI offered cost saving recommendations. For example, in one building, it was intended for the existing diesel generator set to be replaced. However, an analysis of the emergency load requirements in the building revealed that the emergency loads were only comprised of egress lighting loads. LEI recommended that a Lighting Inverter be installed instead of a diesel generator to save on cost, reduce downtime due to construction phasing, and to allow a smaller installation footprint in the already crowded basement electrical room. During the Bid Phase, the LEI assisted with preparing a Project Work Description, provided support for the Third Party Preparing City of Albuquerque Air Quality Permits, and answered questions from bidding contractors. https://www.lopezengineering.com/airportadditional-lightng daily 0.75 2020-11-03 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1602520987078-03EA1L64O86H4EBJ0PI2/Airport2.JPG Airport-Additional Lighting - San Diego International Airport; Additional Security Light Project Client: San Diego International Airport Location: San Diego, CA Project provided additional security lighting along the fence for three different areas at Lindbergh Field: 1. the East End of the runway extending approximately 3,200 feet; 2. area to the north of the runway extending west from the Federal Express area to Jim’s Air area, a distance of approximately 4,200 feet; and 3. area near the fuel farm extending approximately 300 feet. Light standards were located adjacent on the airport side of the security fence. Light standards were 20 foot or 40 foot in height depending on the area. Others were approximately 10 feet high to allow airplane passage through gates. Each light standard, except for two near the Crash and Rescue Building, utilized FAA approved obstruction light. Some light fixtures were mounted on the blast fence or on the structure referred to as the Summer Cottage where the road narrowed, which prohibited pole installation adjacent to the fence. Existing electrical points of connection belonging to the Port District will be utilized. The electrical circuits will be placed underground in concrete encased duct. Electrical distribution utilized several different voltages depending on the area and whether existing service was available. Some existing service was utilized and some new service was required. Other project elements included panelboards, meters, new SDG&E service, trenching underground duct banks, and dig alert (identification of existing crossings by other utilities). Lighting levels complied with the Illumination Engineering Society of North America (IESNA) recommended criteria. https://www.lopezengineering.com/commercial-alycegereauxpark-renovation daily 0.75 2020-11-03 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1603212871338-6BVDB0DXKHAA8FXXZWJM/Comm_El+Centro+Aquatic+Center+.png Commercial-El Centro Aquatic Center - El Centro Aquatic Center Client: City of El Centro Via Location: El Centro, CA Key personnel J.

(LEI) served as a sub-contractor to NorthStar Engineering, which had the prime contract with Caltrans. This task order is part of the IDIQ that NorthStar with LEI as a sub-consultant has with Caltrans. Key LEI personnel included John Lopez, PE, Neil Sherer, Bela Wouters, Donald Crawford and Wesley Breckenridge. The LEI team designed the electrical and SCADA systems for the Collier Tunnel SRRA on SR199 just south of Collier Tunnel, approximately four miles south of the CA-OR border. The wastewater system consists of a lift station receiving liquid from the toilets and sinks; a urine tank receiving liquid from the urinals, a septic tank, two up flow solids tanks, two anaerobic filter tanks; an equalization tank, a secondary treatment tank, headworks with filter flush feature, and three dispersal field zones. System Control and Data Acquisition (SCADA) acquires data from and/or controls level sensors, float switches, scum/sludge sensor study, liquid meters, valves with valve actuators, pump electrical current sensors, calendar, run time meters, and starters. The XiO SCADA system is used for data acquisition and control. Typically, this system is installed by an electrician in one day, the system testing is performed using the cloud, and the installation price is approximately 90% less than the SCADA normally used for this application. LEI developed the Sequence of Operation (SOO), ladder diagrams, control panel layouts, site plans, conduit schedules, and equipment schedules. Level sensors with adjustable settings start and stop some pumps while time measurements (time duration) start and stop other pumps and control the valve actuators. Float switches provide a failsafe backup pump control system. The engine generator is monitored by the XiO, which documents starts, stops, load, and runtime. LEI design increased the electrical capacity at the Collier Tunnel SRRA site by a factor of three (from 37.5 kVA to 112.5 kVA) and brings 3 phase 480-volt service to the site to serve pump motors 1/2 HP and larger with 3 phase 480-volt power compared to the existing 240-volt singe phase service, which currently serves the Collier Tunnel SRRA. This 3 phase 480-volt power is brought to the site by removing two 2/0 electrical conductors from a 1 1/2" conduit and installing three #1 electrical conductors and a #6 ground conductor in that same 1 1/2" conduit. The distance from the electrical room at the North end of Collier Tunnel to the Collier Tunnel SRRA at the Collier Tunnel south end is approximately 2,300 feet. LEI designed a step-up transformer, 480V, 3 Ø, 3 W to 600V, 3 Ø, 3 W, at the north end’s electrical room and a step-down transformer, 600 V, 3 Ø, 3 W to 480Y/277V, 3 Ø, 4 W, at the south end. The transformers with their load taps can eliminate the voltage drop for that distance and increase the available power three-fold. https://www.lopezengineering.com/emergency-lanl-diesel-generator daily 0.75 2020-11-03 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1603229173635-INVD3AQXY4OUIWMHM63Z/Screen+Shot+2020-10-20+at+2.26.01+PM.png Emergency-UNMH Commissioning EG 4-5 - Electrical Services for UNMH Commissioning of Engine Generators 4 & 5 at UNMH & BBRP Hospitals Client: University of New Mexico Hospital (UNMH) Location: Albuquerque, NM Lopez Engineering, Inc. (LEI) was contracted as a third party reviewer of the generator 4 & 5 project for the University of New Mexico Hospital. Responisilities included review of the construction documents, contracts from contractors, and commissioning procedures provided by the design engineer. At the onset of the project, the installation and commissioning of the engine generators was nearly one (1) year behind schedule. Review of the construction drawings and specifications revealed that all project requirements were not being met, including NFPA 110 required tests. The required tests included full load tests of each new generator and system acceptance testing which required a primary power failure be initiated by opening ALL switches or breakers supplying primary power to the facility. Upon review of this requirement, the state fire marshal refused to allow such a test on an existing Trama One center. The design engineer then had to alter the project specification requirments to the new, not yet adopted, 2010 Edition of the NFPA 110, which required a power failure be simulated by opening the normal feed to one of the hosital’s automatic transfer switches. In addition to reviewing the contract documents and ensuring the Hospital received the system designed, LEI provided Submittal reviews, site inspections, witnessed systems testing and attended weekly coordination meetings. LEI provided third party review of UNMH’s Engine Generator 4 & 5 commissioning. LEI reviewed the documents, developed a list of all requirements contained in the contract documents, developed a commissioning document including sign offs for all testing and close out requirements associated with the commissioning. https://www.lopezengineering.com/emergency-unmh-commissioning-eg-4-5 daily 0.75 2020-11-03 https://images.squarespace-cdn.com/content/v1/5f57ef70f7a8424a522af18f/1603229173635-INVD3AQXY4OUIWMHM63Z/Screen+Shot+2020-10-20+at+2.26.01+PM.png Emergency-Ft Belvoir Bldg 361 - Ft.
