Improvements In Exploration Programs And Presentation Of Geotechnical Information: Program Management Approach, Milwaukee Water Pollution Abatement Program

The Milwaukee Metropolitan Sewerage District (MMSD) has been working since mid-1977 on a fast track to meet a court-imposed schedule to rehabilitate a large wastewater collection and treatment system at an estimated cost of $1.7 billion. Because of glaciation, the Milwaukee area has an extremely complex geologic environment. The rock surface ranges from outcroppings in the northern and western parts of the area to 76 m (250 ft) below the surface at the mouth of the Milwaukee and Menomonee Rivers. Bedrock beneath the glacial mantle is a thick sequence of early to middle Paleozoic sedimentary rock. To cope with the many complexities of this large public works project, a Program Management Office (PMO) concept has been employed. A Geotechnical Engineering Group was established within the PMO to provide a continuous , unified approach to geotechnical engineering and full disclosure of all geotechnical information in the construction contract documents. It provides qeotechnical engineering to design and construction, develops and maintains a qeotechnical data base, and participates on the claims resource team.
