Building 385 – Design for Installation of new VAV Boxes with Associated Equipment and Controls and Design for Installation of new Exterior Ducting for Outside Air Ventilation

NNSA Service Center, Albuquerque, New Mexico

Remove and replace all VAV boxes and associated equipment and controls. Connect the VAV boxes to the new DDC system. Provide relief air fans to the outside in the south section and east central areas of all floors in this building. Locate the relief air fans in the ceiling space. The fans shall be integrated with the new DDC system so as to modulate the amount of relief air discharged from the respective spaces. In conjunction with this, the blocked return air passages shall be opened to increase available free area for return airflow. The existing fan coil units located on the south end of each floor shall remain operational as a redundant system for these spaces. For each air-handling unit, disconnect the existing outdoor air louvers in mechanical room from the exterior wall. Add vertical ductwork to the outdoor air penetration on the exterior wall of each unit and route to a gooseneck at least 6 feet above the roof of the building. Coordinated the specifications and did the quality assessment review. The design fee was $19,700. Construction amount: $400,000. In Construction.

Building 381 Interconnect HVAC Renovation Project-Design T02 – Phase I; NNSA Service Center, Albuquerque, New Mexico

Demolition and removal of the existing pneumatically actuated Variable-Air-Volume (VAV) Boxes. Installation of new electrically actuated VAV Boxes. Demolition and removal of the existing equipment associated with the existing HVAC control system. Installation of a new Direct Digital Control (DDC) System to control the 381 Interconnect HVAC System -- System software will reside in a NNSA SC server. Modify the Building 381 Fresh Air Intake System. Install a return air vent (grille) in the ceiling of the 2nd Floor, South End Conference Room. Connect duct work to two (2) existing VAV Boxes. Coordinated the specifications and did the quality assessment review. The design fee was $15,000. Construction amount: $700,000.

SDCRAA Terminal 1 Upgrade, Gates 1 and 2 Remodel San Diego International Airport, Lindbergh Field; San Diego, California

Demolition and removal of existing gates 1 and 2 area except for shell. Design of Electrical, lighting, public address system, EVIDS, SWA infrastructure, telephone system, airport security system and TSA security system. Initially prepared design-build criteria and then contract documents. Provided construction administration services. Coordinated the specifications and did the quality assessment review. The design fee was $190,000. Construction cost $6,000,000 ($1,500,000 electrical portion)

Building 385 Installation of new DDC BacNet System with new variable frequency drive, NNSA Service Center, Albuquerque, New Mexico

Replace existing pneumatic control system with a new open protocol direct digital control system complete with all necessary equipment to monitor and control all building HVAC needs. Alarms will indicate temperature and pressure measurement’s problem areas as well as equipment failures. The new control system shall restore the economizer cycle capabilities of the system to save energy when outside air temperatures permit. Install one new VFD on each of the two AHU’s fan motors. Restore the ductwork system back to its original configuration. This includes removing the cross-connection between AHU-1 and AHU-2. Remove inlet vanes from the main supply fan and all associated non-operating controls equipment. Coordinated the specifications and did the quality assessment review. The design fee was $30,200. Construction amount: $600,000.
