15. Question: There appears to be various utilities to be identified (exposed) after marking or exploratory by pothole or by vacuum excavation. The cost to Relocate them will be more than your budget ($1,000,000) limit. My questions: will you approve additional RFI funding to have them relocated by contractor or will relocation be done by owner prior to installation? If contractor will relocate, any permit required by contractor from owners?

Response: None of the existing unities is anticipated to be relocated except for 3-inch buried Gate Valve (approximately 4 feet deep) and shallow street light box (29”X 23X 12”) to be relocated in same vicinity at Headworks Area (See attached picture # I). No permit is required except the approval of the COR prior to relocating. The cost for relocating of these two items shall be included in the contractor’s bid proposal.

16. Question: Secondly, relocating utility is a daunting task requiring time especially when different outside Agency owners are involved. 120 completion days might not be enough

Response: No. (see response to question #15 above).

17. Question: when we tie into the existing 6” pipeline, will we need to bypass that existing 6” line or will the existing 6” pipeline be shut down by the owner prior to our pipe connection.

Response: The contractor shall provide and install all required piping, fittings, supports, incidentals, services, and labor required to bypass the girts flows from the Grit Chambers to the Headworks during the construction period including the final tie in. The contractor shall replace the existing temporary two 6-inch pipelines bypass system with new temporary two 6-inch bypass system between the Grit Chambers and the Headworks.

(See attached picture # II) considering liquidation count. If contractor will relocate utility will you consider doing in phase thereto extending contract completion date?
