Wright Pierce Engineering Cost Summary
The Wet Weather Influent Screening Upgrade Project was designed by Wright
Pierce and involves the replacement of the 2 existing screen and rakes along with
other upgrades to the Wet Weather Facility. The project was recently bid and
Waterline Industries Corporation was the low bidder. The project will require
construction management and Wright Pierce was asked to provide a scope and
cost proposal for this service.
Construction is estimated to last 11 months and Wright Pierce’s services will
include residential engineering and construction administration. Their cost
proposal of $148,800 is approximately 12% of the $1,237,677 construction costs.
