Raw Water Supply Line Air Valve Inspection

The City of Irving is seeking bids for the inspection of 98 air valves as part of a 32-mile section of the Lake Chapman Water Supply System. The successful bidder will be responsible for installing pressure data loggers and inspecting the air valves. The City encourages electronic bidding and requires bidders to submit their response to this bid electronically. The City will handle the valves, and the contractor will provide the loggers. • The inspection will include 98 air valves. • The contractor will be responsible for getting supplies to the manholes. • Most valves are accessible by truck, but the City will assist with access to each valve. • Photograph documentation will be sufficient for the inspection. • The typical pressure range is 80-100 psi, but it varies depending on valve location and flow rate.
