Yuma Proving Ground

Yuma Proving Ground

Location: Yuma Proving Ground
Owner: U.S. Army


Sain Engineering Associates, Inc. (SEA) was hired by the U.S. Army Engineering and Support Center, Huntsville (CEHNC) to perform a Level 1 Energy Assessment across more than 200 buildings and more than 1.6 million square feet of covered facilities at Yuman Proving Ground (YPG) in Yuma, AZ.  Through this assessment, various energy conservation measures (ECMs) were identified as opportunities.  Technologies included: lighting and lighting controls, solar photovoltaic (PV), plumbing fixtures, variable refrigerant flow (VRF), retro-commissioning (RCx) and direct digital controls (DDC).  SEA provided CEHNC and YPG the tools to analyze and bundle different ECMs as a part of the Level 1 assessment.  CEHNC and YPG bundled the feasible ECMs into projects that could be developed into an RFP package.

Scope of Work

CEHNC hired SEA to develop RFP packages from the feasible projects.  The RFP packages consisted of a written scope of work (SOW), 35% concept design, and a budgetary construction cost estimate.  The deliverables were completed in August 2017 and are defined below:

• SOW – written description for a specific project that may be competitively advertised/bid, contracted, and implemented

• 35% Concept Design – equipment schedules, product cut sheets, instructions sheet, and applicable drawings and specifications

• Construction Cost Estimate – budgetary cost estimate with data obtained from local vendors and industry accepted resources, such as RSMeans

These packages were developed for YPG to competitively bid and for a design-build contactor to easily complete the design and construct the project.  SEA revisited the identified buildings to confirm ECM technologies were feasible as well as remained applicable at the respective buildings and to gather information for RFP package development.

After the site visit was complete, SEA developed the SOWs, 35% concept designs and construction cost estimates for the bundled projects.  The projects were lighting / lighting controls, plumbing fixtures, solar PV, and mechanical (VRF, Controls, RCx).

SEA worked closely with CEHNC and YPG to ensure project expectations and goals were met.  CEHNC and YPG now have RFP packages ready for bid and feasible projects that will drive down YPG’s energy costs.
