2026 Sewer & Drain Improvement Project

The City of Nashua, New Hampshire is issuing an Invitation for Bids (IFB) for the 2026 Sewer & Drain Improvement Project, a municipal infrastructure procurement focused on sewer and drain system upgrades across four locations: Middle Dunstable Road, Hills Ferry Road, Dunloggin Road, and 167 Cypress Lane. The project scope encompasses over 70 line items including pipeline and structure replacement, catch basin and manhole installation, excavation work (203 cubic yards of rock excavation and 100 cubic yards of unclassified excavation), pipe installation (80 linear feet of 12-inch polypropylene pipe and 490 linear feet of 18-inch polypropylene pipe), drainage structures (two catch basins and seven drainage manholes), sewer service work (300-420 linear feet of 8-inch PVC sewer pipe), and pavement restoration work (1,730 square yards of temporary and permanent patches with 380 square yards of driveway reconstruction). Bidders must be pre-qualified on the New Hampshire Department of Transportation's contractor list with appropriate road and/or site classifications and must demonstrate sufficient bonding capacity, including a 5% bid bond, 100% performance bond, and 100% payment bond. Required insurance includes General Liability of $1,000,000 per occurrence/$2,000,000 aggregate, Motor Vehicle Liability of $1,000,000 combined single limit, and Workers' Compensation coverage per state statute, with the City of Nashua named as additional insured. The bid package was posted on May 15, 2026, with an optional pre-bid meeting held on May 21, 2026 at 10:00 AM (Zoom participation available), bidder questions due by May 27, 2026 at Noon, question responses posted by May 29, 2026 at 2:00 PM, and bids due on June 9, 2026 at 2:00 PM via electronic submission through Bonfire or paper form with USB drive. Substantial completion is required by November 1, 2026, with final pavement completion by May 30, 2027, and liquidated damages of $1,280 per working day will be assessed for delays beyond these dates. The contract will be awarded to the lowest responsive and responsible bidder based on the Schedule of Values with unit price and lump sum elements, and all bids must remain valid for 90 days following the bid deadline.

No specific set-aside designations for disadvantaged enterprises or minority-owned business enterprises are identified in the procurement documents provided. Bidders must comply with work restrictions including the requirement to obtain Right of Entry Agreements from homeowners at 167 Cypress Lane and 3 Chinook Road before construction begins (agreements expected by July 15, 2026) and the restriction that work adjacent to Salmon Brook must occur during low-flow summer months. The project requires coordination with existing water, gas, sewer, and drainage infrastructure, with contractors obligated to contact Dig Safe 72 hours prior to construction and verify utility locations based on field survey information. The engineering plans were prepared by IMEG Corp. and specify adherence to New Hampshire Department of Transportation standards and ASTM specifications for all construction practices, trench sections, bedding materials, and manhole construction. Progress payments will be made monthly with 10% retainage until 50% completion is achieved, after which retainage is held only if quality or timeliness issues exist, with 2% final retainage held during the one-year warranty period. No specific budget or award value is listed in the procurement documents, with the contract value to be determined by the lowest responsive and responsible bid submitted.
