City of Manassas, Fire & Rescue Station #21
Inherent challenges on this project site included shallow shale/siltstone bedrock, silty/clayey soils, and remnants of former residential structures and drain fields. In addition, a significant cut slope was required at the rear (west) and north sides of the project. During the due diligence study, WDP evaluated the site constraints related to shallow rock and silty/clayey soils by providing recommendations to minimize construction challenges and excessive costs, and to maintain long-term slope stability. WDP’s special inspection and materials testing services for soils, concrete, CMU, and structural steel have provided quality assurance to the City of Manassas that the project is being built in accordance with the approved/permitted plans and specifications.
