Specifications include, but are not limited to: The Sevierville Water and Sewer Department (SWS) will accept unit price bids on one or any combination of the desired materials specified. Prices must be good for a period of one year for FY 2009, July 1, 2008 through June 30, 2009; however, by mutual consent of both parties, the bid may be extended in one (1) year increments up to three (3) additional years at the same unit prices. All bids must be submitted on the prescribed bid form with unit and total bid prices indicated. Any and all freight expenses are included in the bid prices and materials shall be delivered to Owner at no additional charge. Bidder shall also provide with his bid a statement with regard to the delivery time. While this bid is for an annual supply of precast manholes, precast inverts and connectors, Owner agrees to renegotiate unit prices based on documented changes in raw materials prices. However, should price changes fail to be negotiated to the satisfaction of either party, Owner or the Bidder may, at the option of either party, cancel the balance of the one-year supply contract.
