NAVFAC Southwest - MCAS Yuma Building 233 Photovoltaic Addition
Yuma, AZ

In 2005, Syska Hennessy Group Construction was awarded an IDIQ MACC to service the Southwest region, encompassing California, Arizona, Nevada and New Mexico. The scope of work for this project included new construction and repair of dry utilities, including electrical distribution, lighting systems, solar photovoltaic systems, cable television lines and communication transmission lines. Syska Hennessy Group was selected to provide electrical engineering for multiple projects.

One significant project completed from this IDIQ contract is MCAS Yuma Building 233 photovoltaic addition. This is the first solar energy project completed by the Marine Corps with funds from the American Recovery and Reinvestment Act (ARRA). Additional incentives were received from Arizona Public Services.

Syska engineers were involved from the beginning. The team conducted the initial field investigations which yielded concept designs that were coordinated with the PV contractor. Additionally, Syska provided design oversight which included verification of calculations, direction to structural consultants and coordination of metering equipment. A complete QA/QC review was performed to ensure design quality and compliance with initial concepts and NAVFAC standards.

NAVFAC’s original RFP requested the system feature panels that used thin-film technology. After consultation with Syska, NAVFAC decided to use crystalline modules to meet the end-users energy production requirements with the limited roof area available. The solar array is composed of 189 photovoltaic panels and provide 33kW of power to serve building 234. This design will save approximately $8,000 to $9,000 in annual electrical costs.
