Item Description 3.0 – QUESTIONS AND ANSWERS The following questions and answers are provided as a matter of information to clarify issues raised about the Bid Documents. Item Questions and Answers 1 2 3 4 5 Is there an established unit price or allowance baseline in the RFP for dewatering due to high groundwater tables? RESPONSE: No that is incidental to the project and will be the responsibility of the vendor to build into the base bid item. What are the operating and static pressures at the existing water main connection point? Is a wet tap tee and gate valve assembly required at the connection to preserve service continuity, or will a localized off-peak main shutdown be permitted? RESPONSE: Static system pressure is approximately 62psi. The last fire flow test performed in May of this year showed a Residual pressure of 19psi at a flow rate of 590gpm at a fire hydrant on the west end of Samual Bowen Blvd. A wet tap will not be required as there is a stub with a valve at either end of the existing water mains of this project. Are there specific locations, intervals, or minimum counts required for line valves, blow-off assemblies, or fire hydrant configurations along the 2,000 linear foot alignment? RESPONSE: Yes. Provide four complete hydrant assemblies with spacing not exceeding 500 feet. Each hydrant shall include a 6-inch lead and isolation valve.
