US Coast Guard Facilities Design & Construction Center

PROJECT DESCRIPTION
Our company completed the design and participated in the construction phase services of this design-build project.  Working with contractor Adira Construction, located in Chesapeake, we designed the replacement of most of the on-site water mains at this Coast Guard training base by converting a separate domestic/fire system to a combined one.

SPECIAL DESIGN FEATURES
The conceptual design was provided by USCG FDCC with the RFP for the project.  We worked closely with Adira’s subcontractors to optimize the design for constructability and cost savings.

The entire system was modeled using WaterCAD to assure design fire flow/pressure requirements could be met at critical buildings on the base.

The original design concept was based on having two 12” offsite mains feeding water from Newport News Waterworks to the edge of the base.  Later, it was found that one of these feeds could not be provided.  This led to a change order for the design of a 2,000 gpm on-site water pumping station to be used in conjunction with a re-purposed 0.1MGD elevated tank.

We interacted with the construction contractor on site for field inspections and gathered data for the preparation of construction record drawings.
