DC Water’s Clean Rivers (DCCR) project is an ongoing program to reduce combined sewer overflows into the District’s waterways—Anacostia and Potomac Rivers and Rock Creek. The Main Pumping Station Diversions (MPS-D) Division I Project was a component of the overall DCCR project to permit overflows via the Blue Plains Advanced Wastewater Treatment Plant. The work for this portion of this project occurred to the north of the MPS at the intersection of Tingey St. SE and New Jersey Avenue SE and included storm surge storage to provide surge relief and reduced surge water surface elevations during critical rain events.

Division I has been constructed in accordance with DC Water Contract Specifications, meeting the standards of the industry for both design and construction.  Quinn’s past experience on design-build projects has led to the development of a proven Design and Construction QA/QC program that provides complete and comprehensive procedures which address all phases of project process from initial design through construction to final acceptance.

Quinn provided quality management services in the position of QA/QC Manager for this public-private partnership (P3) design-build project in addition to QA on-site management and inspection services. As full-time on-site QA Manager/Senior QA inspector(s), Quinn managed and staffed the Project’s construction materials testing and inspection program through the production of inspector’s daily reports (IDRs) and supporting documentation for inspection and testing activities, including material sampling and acceptance.
