LEGACY FIELD SYNTHETIC TURF REPLACEMENT

ADDENDUM NO. 1

November 10, 2026

RFP issued: November 5, 2026 Bid deadline and public opening: November 20, 2026, at 10:00 a.m. Eastern Time

This addendum modifies the RFP and becomes part of the bid and contract documents. Where this addendum conflicts with the original RFP, this addendum controls. Bidders must acknowledge receipt on the bid form.

1. Turf construction preferences and eligibility

References in the original RFP to particular turf construction, permanent marking and seam methods describe the District’s preferences. These methods are not mandatory. Other construction methods are equally eligible when the proposed complete system meets the published requirements or demonstrates documented technical equivalency.

Bids are invited from all manufacturers and for all styles of outdoor athletic synthetic turf suitable for the specified uses, subject to the requirements below. No manufacturer or proprietary turf technology is required.

Eligible constructions include slit-film, monofilament, blended-fiber and systems incorporating a texturized thatch or root-zone layer. Manufacturer-approved factory-tufted, inlaid or other equivalent permanent markings and sewn, bonded or combined roll-seam methods may be proposed.

No manufacturer, fiber style, marking method or seam method will be excluded solely because it differs from the District’s initial preferences.

2. Required standards and documentation

All proposed systems must satisfy the RFP’s requirements for intended athletic uses, Michigan weather exposure, pad compatibility, permanent markings, installation quality and the minimum eight-year non-prorated manufacturer and installer system warranty.

All testing and acceptance requirements in Section 8 remain unchanged and apply equally to every proposed turf system. Existing pad inspection and approval requirements also remain in effect.

The nominal 2.0-inch pile height and minimum nominal face yarn weight of 40 ounces per square yard remain the reference construction specifications. A bidder offering different construction characteristics must identify each difference and submit product-specific technical evidence demonstrating equivalent suitability, durability and complete-system performance.

Submit the exact manufacturer and model, component specifications, marking and seam methods, applicable test reports, proposed warranties and a comparison addressing each difference from the

reference specifications. Test reports shall identify the tested turf, infill and pad configuration and explain differences from the proposed system.

A product name, brochure or unsupported claim of equivalency is insufficient. Acceptance of a proposed equivalent is subject to District review against the published requirements.

3. Equal consideration and award method

All responsive systems meeting the published requirements, including documented equivalents accepted by the District, will receive equal consideration. No manufacturer, fiber construction, marking method or seam method will receive additional weight, a price premium or priority solely because it matches the District’s initial preferences.

Price and quality are the District’s primary considerations. Quality will be evaluated through documented compliance with the published requirements for performance, durability, materials, installation, warranty and suitability for the intended uses. Bidder qualifications will be evaluated under the requirements stated in the RFP.

The District retains its preference for white or light-colored reduced-heat infill and may select either required infill option after evaluating bid prices, documented cooling performance, maintenance requirements and warranty coverage.

For the selected pad scope and infill option, the District intends to award to the lowest-priced responsive bidder determined to be responsible and qualified. All bidders will be compared using the same scope. A lower price does not excuse failure to meet a mandatory requirement.

Award remains subject to Board approval, available funding and the District’s right to reject any or all bids.

4. Bid pricing

Bid pricing: The four required pad and infill pricing combinations remain unchanged. Bidders may use the original pricing form, identifying the exact system offered. The “preferred” and “alternate” turf-construction labels no longer establish separate award categories or priority. A bidder need not submit duplicate prices for the same system under both labels.

5. Site visits and questions

Bidders needing a site visit shall contact Matt Andres, Director of Finance, at matt.andres@gpsjackets.org to arrange a District-supervised visit at Legacy Field, 111 N. Hillcrest Street, Greenville, Michigan 48838.

No additional group walkthrough is scheduled.

Attendance at the November 9 walkthrough was not a condition of bid eligibility. The original mandatory site-visit requirement is replaced by this paragraph. Bidders remain responsible for verifying dimensions, layout and reasonably observable conditions. No destructive inspection or disturbance of existing materials is permitted without prior written District approval.

Written questions remain due November 18, 2026, at 12:00 noon Eastern Time. Information from individual site visits that materially clarifies or changes the bidding requirements will be shared by written addendum. Oral statements do not modify the RFP.

6. Dates and remaining requirements

The sealed bid deadline and public opening remain November 20, 2026, at 10:00 a.m. Eastern Time, in the Community Room at the Central Services Facility, 1414 Chase Street, Greenville, Michigan 48838.

Substantial completion remains May 15, 2027. Final completion remains June 1, 2027.

This addendum supersedes conflicting construction-preference and eligibility language on the RFP cover and in Sections 2, 6 and 10. All other requirements remain unchanged, including prevailing wage, required registrations and certified payroll, bid security, affidavits and sealed physical bid submission.
