2023 blow-off replacements

Cobb County-Marietta Water Authority is requesting sealed bids for the 2023 Blow-Off Replacements project on a 36-inch water main, with bids due July 1, 2022 at 11:00 a.m. at 1170 Atlanta Industrial Drive, Marietta, Georgia, and a mandatory pre-bid meeting on June 15, 2022 at 11:00 a.m. at the CCMWA A&E Building. Only contractors pre-qualified with CCMWA to construct ductile iron water mains of 36-inch and larger diameter (Categories 2, 3, and 4) at the time of first publication are eligible to bid — a restrictive prequalification requirement that controls the bidder pool.

The scope entails replacing four existing 6-inch saddle blow-offs with 36-inch by 8-inch or 6-inch tees and corresponding blow-offs; removing two 6-inch saddle blow-offs; and replacing one 36-inch by 12-inch saddle with a 12-inch outlet valve and 36-inch by 12-inch tee and 12-inch gate valve. Substantial completion is required within 90 consecutive calendar days, and final completion within 120 consecutive calendar days from commencement.

Each bidder must hold a Georgia-issued Utility Contractor license and submit a bid bond or certified check equal to five percent of the total contract amount, along with a notarized non-collusion affidavit. Out-of-state entities must provide evidence of authority to conduct business in Georgia. The successful bidder must furnish performance and payment bonds and an oath pursuant to O.C.G.A. Section 36-91-21. All bids remain subject to acceptance for 60 days following bid opening, and CCMWA reserves the right to reject all bids and re-advertise.

The engineer for the project is Engineering Strategies, Inc. Bidding documents are available for purchase at Engineering Strategies, Inc., 3855 Shallowford Road, Suite 525, Marietta, Georgia 30062, for $50.00 per set.
