Owner: Town of Concord

Partner: D&C Construction

Type: Access Platform/Trestle, Subaqueous Pipeline

Location: Acton, Massachusetts

Project Description: For this project, H.B. Fleming fused and installed 1,100 linear feet of 20″ pipe, connected new pipe to the existing pipeline, and designed and fabricated a pile-supported frame to support the intake. 

Challenge: Install a new drinking-water intake with strict limits to access and disturbance to the water source. Soft ground conditions required a last-minute design-build intake support frame. 

Solution: A floating–access trestle/work platform was used to limit the disturbance to the pond and create working room. H.B. Fleming’s in-house engineering was able to design a pile-supported intake structure to keep the intake from sinking below the mudline.
