This project involves the replacement of existing undersized steel mains with new 8” ductile iron piping in Lake Forest Park.
Consultant: Murray, Smith and Associates
District’s Estimated Construction Cost: $776,000
Schedule: the project is currently at 90%; we are awaiting input from the State of Washington regarding the design. Construction is anticipated to be completed in late Winter/early Spring 2013
Would someone be able to tell me how much pipeline (length) you got for your $776,000?
The cost of this project involved more than just new pipeline. In addition to approximately 2,120 linear feet of 8-inch ductile iron pipe (which requires not just the piping, but also pipe bedding, trenching / backfill, full slurry seal, surface restoration, and decommissioning the old line), we also installed 6 fire hydrant assemblies, 1 combination air/vac valve assembly, and replaced 48 service connections. The best news is, the cost of this project came in under the original estimate by more than $200k: its final construction cost of $521,763.19 included all of the above scope—from design, permitting, and construction administration, to construction and final inspection.
Thank you!
