DPW: Bid - Frames & Grates

The City of Manchester’s Public Works Department is soliciting sealed‑bid proposals for the supply of cast‑iron frames, grates, manhole covers, and polyethylene catch‑basin liners used in municipal storm‑ and sewer‑drain systems. Bidders must provide U.S.–made products that meet AASHTO M 105/M 306 cast‑iron specifications, include required shop drawings, and furnish a one‑year warranty covering material, labor, and travel. Delivery must be rapid—stocked items within 48 hours and non‑stocked items within seven working days—and the City will award the contract on a “lowest responsible bidder” basis, potentially on a line‑item or partial basis. The contract runs through April 1 2027 and may be extended under the same terms. • Supply of Class 30 cast‑iron frames, grates, and covers (various sizes) plus polyethylene liners. • All items must be manufactured in the United States and stamped “DRAIN” or “SEWER”. • Firm, all‑inclusive unit pricing; City may add $2.20/mi transportation allowance for pickups. • Mandatory compliance with HUD/CDBG, Davis‑Bacon, equal‑opportunity, and hazardous‑material labeling requirements.
