The Detroit Water and Sewerage Department (DWSD) needed to rapidly and cost effectively design and construct a modern, efficient water treatment plant. Using a life-cycle cost analysis, PMA recommended building a new plant instead of rehabilitating the existing plant. This project involved oversight of a $288 million design-build-maintain contract to replace the existing water treatment plant at WaterWorksParkwith a new 240-mgd plant.
After assisting the DWSD with identifying the appropriate requirements for the new plant, PMA helped prepare a request for qualifications and a request for proposals to procure a design-build-maintain contractor for the project. PMA also developed design-build-maintain contract documents and assisted the DWSD in evaluating proposal responses.
During the project, PMA reviewed project schedules, contractor payment requests, costs, changes, and claims. PMA also provided project administration, document control, and records management to monitor progress and to assure that contract requirements were satisfied, owner interfaces were properly identified with sufficient time allowances, and that schedules presented a fair and responsible basis for evaluating time extension requests and delay claims. At completion of the project, PMA provided expert services to assist the DWSD by cost effectively resolving litigation filed by the design-build contractor.
