Memorandum
Attached for your review and approval is a resolution to award a contract to Site Development, Inc. in the amount of $720,387.20 for the Vaughn St./ Nob Hill/ Copley Ave./ Harbal/Leaird Dr./ Yost Alley Water Main And First Street Sanitary Replacement Project.
The construction contract titled "Vaughn St. / Nob Hill/ Copley Ave. / Harbal & Leaird Dr. / Yost Alley Water Main and First Street Sanitary Replacement Project" includes the installation of new 8" and 12" water mains at several different locations in the City. The locations are combined in one construction contract for efficiency and cost savings.
The Vaughn Street water main includes the installation of approximately 690 feet of new 8" ductile iron water main to replace the existing 4" water main that serves the houses on Vaughn Street. The fire hydrants on Vaughn Street have inadequate flows. This work will provide a more reliable water service for the neighborhood, and conform to City of Ann Arbor water main and fire protection standards by upsizing the pipe. Vaughn Street is scheduled to be resurfaced by the city resurfacing project this year, following the water main work, which will also replace adjacent sidewalk ramps to comply with ADA requirements.
The Nob Hill water main includes the installation of approximately 2,663 feet of new 8" and 12" ductile iron water main to replace the existing 6" mains that serve the apartment houses on Nob Hill, and the houses on South First Street and West Davis Ave. Nob Hill and South First Street have a history of water main breaks that have disrupted service. The water main replacement will extend north to Madison in order to improve fire flows appropriate for a high density residential population. This work will provide a more reliable water service for the neighborhood, and conforms to City of Ann Arbor water main and fire protection standards by upsizing the pipe, connecting to a larger pipe in Madison, and adding seven fire hydrants. The work will also include the replacement of 350 feet of 8" sanitary pipe which is failing in South First Street north of Koch Ave. Following the water main and sanitary pipe work, West Davis Ave and South First Street between Koch and Davis is scheduled to be resurfaced by the city resurfacing project this year, with replacement of adjacent sidewalk ramps to comply with ADA requirements.
The Copley Ave. water main includes the installation of approximately 1,075 feet of new 8" ductile iron water main to replace the existing 6" main that serves the houses on Copley Ave and Tappan Middle School. The fire hydrant on Copley Ave. has inadequate flows, and Tappan Middle School fire hydrant coverage is inadequate. This work will conform to City of Ann Arbor water main and fire protection standards by upsizing the pipe and adding two fire hydrants. The Ann Arbor Public Schools will be reimbursing the city for work done on school property, (approximately 700 feet of water main and two hydrants), and performing their own restoration & resurfacing of the parking lot.
The Harbal & Leaird Drives water main includes the installation of approximately 1,130 feet of new 8" ductile iron water main to replace the existing 4" and 6" mains that serve the houses on Harbal and Leaird Drives. Residents on Harbal and Leaird Drives have complained about water quality. This work will provide a more reliable water service for the neighborhood, and conform to City of Ann Arbor water main and fire protection standards by upsizing the pipe, and adding three fire hydrants.
The Yost Alley water main includes the installation of approximately 750 feet of new 8" ductile iron water main to replace the existing 4" main that serves the businesses on the alley between Yost and Pittsfield Blvd. Yost Alley has a history of water main breaks that have disrupted service. This work will provide a more reliable water service for the neighborhood, and conform to City of Ann Arbor water main and fire protection standards by upsizing the pipe and adding a fire hydrant.
At all work locations, the storm system will be upgraded by replacing drop inlets with 2' diameter structures, as requested by Field Operations.
