Memorandum
Attached for your review and approval is a resolution to award a construction contract to Douglas N. Higgins, Inc. in the amount of $397,059.00 for the Village Oaks/Chaucer Court Emergency Storm Sewer Overflow Project.
During certain storm events, since the 1980s, the area between the west boundary of the Village Oaks Subdivision and the east boundary of the Landsdowne Subdivision near Chaucer Court has experienced backyard and basement flooding. A relief sewer was constructed in 1991 to address this area, but flooding problems persist.
In 2010, Resolution R-10-365 was adopted by Council for a drainage study for this neighborhood. The study was to define the tributary area, assess existing conditions, evaluate alternatives and make recommendations to alleviate the flooding. A key component of the study involved working collaboratively with impacted residents. Key findings and recommendations from the study, and their current statuses, include:
1. Construction of a regional stormwater detention basin to collect, detain, and then slowly release stormwater from the upstream watershed. Status: the City entered an agreement with the developer of 2250 Ann-Arbor Saline Road for construction of the basin, which should begin soon.
2. Field investigation revealed a number of outlet restrictors were missing on the existing upstream detention basins. Status: The missing restrictors have been re-installed in these upstream detention basins.
3. Identification of the need for additional catch basins in a few street intersections.
Status: Catch basins have been added at these locations.
4. Lack of an emergency stormwater overflow for the Village Oaks Subdivision. Status: incomplete.
This contract is for construction of the needed emergency overflow identified in item #4 above. Project plans and specifications were distributed electronically to contractors, subcontractors, and suppliers through the City of Ann Arbor’s procurement website and MITN.info. Four bids were received and opened on May 30, 2018. The lowest responsible bid, from Douglas N. Higgins, Inc., in the amount of $397,059.00 is approximately 12% above the Engineer’s Estimate. Attached is a summary of the bids received for the project.
Douglas N. Higgins, Inc. has submitted all required Non-Discrimination, Prevailing Wage, Living Wage, and Conflict of Interest Disclosure forms and complies with the requirements of the City’s Non-Discrimination and Living Wage ordinances.
Construction is scheduled to begin in October and be completed in November of 2018.
