NIGP 66537: Gratings: Fiberglass, Plastic, Poly., etc.

NIGP 66537 Gratings: Fiberglass, Plastic, Poly., Etc., an Item code, covers structural fiberglass grating materials and fastening systems that state and local governments procure for infrastructure projects, particularly pedestrian bridge decking and walkway safety resurfacing. Recent solicitations show state transportation departments sourcing engineered pultruded fiberglass grating in specified panel configurations with UV inhibition, flame-retardant resin, and anti-skid surface treatment bonded for outdoor durability. The Michigan Department of Transportation (MDOT) has been the primary recent issuer under this code, procuring material-only grating supplies for in-house installation crews rather than turnkey construction services. Evaluation under recent RFPs has been straightforward — pass/fail criteria covering completeness of forms, vendor responsiveness, brand and model conformance, and contract terms acceptance, with award to the lowest-priced responsive and responsible bidder. MDOT's procurement notes that qualified Service-Disabled Veteran-Owned Business entities may receive preference consideration under Michigan statute, though recent awards have been made to non-set-aside vendors.

Michigan dominates the recent activity block, with three closely related MDOT solicitations posted between May 5 and May 26, 2026, all targeting the same Merrick Avenue Walkway pedestrian bridge project in Wayne County, Detroit. The initial RFP (RFP5912600000019141) posted May 5, 2026 with a May 19, 2026 due date sought 70 fiberglass grating panels in five size configurations plus fastening hardware for concrete attachment, requiring delivery within 42 calendar days to MDOT Operations Field Services in Lansing. Amendment 1, issued May 13, 2026, clarified panel width specifications following a discrepancy between the originally stated 2'11.75" and the DURAGRID Series T-1700 standard width of 35-13/16". Two proposals were submitted. The Intent to Award notice posted May 26, 2026 recommended GFG Supply Inc. of The Villages, Florida for award at a total contract value of $88,060, with individual panel prices ranging from $2,760 to $65,808; the competing bidder, Swipe Resources LLC of Manassas, Virginia, failed the evaluation due to incomplete responses and failure to affirm contract terms. No geographic spread beyond Michigan or issuing bodies beyond MDOT appear in the source.
