As part of Henry Adams’s direct IDIQ contract with NIH, TCT provided cost estimating services for a 95% draft submission and final submission for the NIH Animal Center (NIHAC). Located on 513 acres, the NIHAC consists of various animal research and holding facilities, a water tower, central heating and cooling plant, and a wastewater treatment plant (WWTP). The NIHAC campus consists of approximately 37 temporary and permanent buildings, a sanitary sew-er collection system, and an activated wastewater treatment plant and recycle water distribution system. The WWTP is made up of preliminary, primary, secondary, solid handling and tertiary treatment systems, with two shallow lagoons. The plant has the ability to treat approximately 100,000 to 125,000 gallons of waste per day, and NIHAC utilizes recycled water from the WWTP for washing down animal pens, cooling tower water, etc.
The scope of work included an assessment, which provided process flow diagrams and narrative of operations, solid loading diagrams, evaluations, and reports on the conditions and performance of the sanitary sewer collection system. This assessment included drawings and recommendations for resolving and improving operational issues and upgrading systems.
