Consolidated Environmental Laboratory Project

2002 Honor Award
American Council of Engineering Companies of Metropolitan Washington

Greeley and Hansen served as bridging consultant representing the Washington Suburban Sanitary Commission (WSSC) as part of an integrated team to complete this successful state-of-the-art water and wastewater laboratory. As bridging consultant, Greeley and Hansen assisted WSSC in establishing the functional design of the facility; assisted with selection of the design/build team; provided construction-phase services; and assisted with facility startup.

Significant features of the 27,000-square-foot facility include a building arrangement that establishes a progressive gradient of air purity from each of the facility's four operationally distinct modules: administrative, mechanical support, sample receiving, and analytical laboratory.

The arrangement includes isolated rooms for microbiology, organic extraction and volatile organic analysis and an open laboratory concept in the primary lab area to maximize visibility and to promote teamwork and collaboration among analysts. A sophisticated HVAC system reduces the possibility of contamination during testing throughout the open laboratory. Analytical lab islands are designed to be independent and to permit rapid, inexpensive reconfiguration of laboratory facilities to meet the needs of new testing regimens.

The new laboratory accommodates a full range of water, wastewater and biosolids analytical lab services, as well as non-analytical support functions all within a single facility. Prior to construction of the Consolidated Environmental Laboratory, WSSC labs were located at eight sites across a 1,000-square-mile area. In addition, the new lab facility enables more precise testing and achievement of accuracies at the parts-per-billion level to meet stringent analysis requirements for monitoring wastewater discharges and public drinking water.
