Ford Construction Uses HeavyJob & HeavyBid on American River
This was Phase II completion of the Intake Structures for the American River Pump Station. Major items of work were: dewatering of the channel; excavation of the existing cofferdam remnants; and major concrete structures in the channel, with intercnnecting piping to the Phase I Pump Station. Channel construction of recreational facilities, diversion of the river back into the channel, closure of the existing Diversion Tunnel, and downstream recreational facilities are also included. The Phase II project consists of concrete Primary and Emergency river intake structures and access road slabs; an Obermeyer-type maintenance gate; channel and cofferdam excavation; channel erosion protection including grouted stone, plain and planted riprap; a complex kayak course built into the final river channel; air and water piping systems in a utility trench uphill to the pump station; a concrete-encased steel casing pipe for a future water pipe beneath the river; and closure of the existing Auburn Dam Diversion Tunnel.
What makes it interesting?
Prior to initiating permanent construction, upstream and downstream cofferdams had to be built and the site dewatered so the river bottom debris could be removed. There were major unknowns to be uncovered, and the debris had to be removed to be processed for later use as riprap and boulders, in a sequence which would not interfere with later operations.
How HCSS Software assisted with this project
Both HeavyBid and HeavyJob were used on this project. Ford’s evaluation of the Phase II project mandated very intensive project management for the successful execution of the project.
