Ann Arbor Water Treatment Plant Rehabilitation

Overview

This program involved three phases totaling over $167 million in design and construction contracts. The successful program included renovating the entire solids handling facility and process; completely demolishing and rebuilding a third of the Ann Arbor Water Treatment Plant primary, aeration, and secondary treatment facilities; and renovating the balance of the primary, aeration and secondary facilities. This 30-mgd plant project is the largest capital program in the city’s history. During construction, the plant remained operational at all times to treat wastewater while demolitions, process changeovers, and renovations took place.

PMA provided services during the design and construction phases for all three construction projects required to complete this program. During the design phase, PMA provided project controls services that included creating preliminary construction schedules, overall program coordination, and providing cash flow analyses. During the construction phases, PMA provided project controls services that included schedule review, schedule analysis, and change order management; PMA also managed the contractor pay request process.
