GOC359119 STAR RFQ Consulting - Consultant - Storm Drain Piping Repairs

This 2 year project is to connect the storm water drain pipes to the combined municipal storm and sewer that exists on Marlborough St adjacent to the property. The City Engineers have indicated a new storm drain is planned for Marlborough St and based on this the storm water should be directed to the existing combined sewer and storm drain and at a later date this storm drain would be connected to the new city storm drain. Complete Plans and Specifications Year 1 and Construction Year 2. Scope will require disconnecting the roof drain down corners inside the building from existing storm and sewer drain and install new storm drain pipes to redirect the flow to Marlborough St sewer/storm drain. Project scope is based on the attached Storm Water study completed in
December 2013. Alternatives: The plans and specifications phase to consider a previous report for options; and other methods to remove this storm rain water quickly from the building during heavy rain storms. During high intensity rainfalls (last occurrence on Wednesday 30 July 2014) the storm drainage piping cannot remove the water from the building fast enough which leads to back up through common sewer lines as both storm and sanitary drains exit the building through the same drain pipe. This scenario happens one to two times per Summer and is rather expensive each time for a full dehydration and sanitization clean up. Completion of this project will prevent indoor mold and bacteria issues and correct the problem of back up flooding from storm and sanitary fluids caused by high volume rain storms.
