Water Treatment Plant Interior Domestic Water Piping Project

The City of Jackson, Michigan is soliciting sealed proposals through a Request for Proposal (RFP) for plumbing services to replace approximately 34 feet of three, four, and six-inch domestic water piping and associated valves, fittings, supports, and appurtenances within the Water Treatment Plant building located at 740 East Mansion Street in Jackson County, Michigan. The RFP was posted on May 15, 2026, with proposals due by May 29, 2026 at 10:00 am via the e-Procurement Portal at https://procurement.opengov.com/portal/cityofjackson. Contractors must submit a lump sum price proposal that includes all labor, equipment, and associated materials for the complete project scope, with the contract term ending August 28, 2026, or upon project completion, whichever occurs first. All materials removed and not reinstalled must be disposed of offsite by the contractor at their own cost. Qualifying contractors must habitually perform at least fifty percent of the work with their own forces and must provide project management approach documentation with primary contact information, professional experience of key staff members, and a proposed timeline. All work requiring the piping system to be out of service must be completed within eight-hour windows between 8:00 am and 7:00 pm on Monday through Thursday and requires coordination with and approval by the Plant Supervisor. Materials must comply with the latest edition of the Michigan Plumbing Code and NSF/ANSI Standard 61, with pipe and fittings specified as ductile iron and all valves as solid wedge rising stem gate valves; catalog cut sheets for all materials must be provided for the Plant Supervisor's review at a preconstruction meeting.

The RFP documents do not specify any set-aside designations or restrictions limiting response to particular organization types, disadvantaged enterprises, or minority-owned vendors. No incumbent vendors or current contractors are identified in the procurement materials. The contract will be governed by a Professional Services Agreement with the City of Jackson, and contractors must maintain professional liability insurance with minimum limits of $1,000,000 per claim for projects with estimated costs of $100,000 or greater, along with commercial general liability and automobile liability coverage of $500,000 per occurrence, and valid workers' compensation and employer's liability insurance. The specific contract award value or budget range is not disclosed in the available RFP documents, though the project's estimated cost threshold of $100,000 or greater can be inferred from the insurance requirements outlined in the standard agreement template. Compensation shall be limited to the not-to-exceed amount identified in the contractor's proposal and shall constitute full remuneration for all services, labor, expenses, and work described in the proposal and RFP, with any extra or additional services beyond the RFP scope reimbursed on a time and material basis subject to owner written approval. Monthly invoices are due for payment within 60 days of invoice date unless disputed, and the City reserves the right to terminate the agreement at any time with seven days' prior written notice, with payment due for all satisfactory work completed through the termination date.
