Geogrid Asphalt Design Alternative

The Portage County Highway Department is seeking proposals for a geogrid asphalt pavement design alternative project involving the reconstruction of County Trunk Highway G from CTH M to CTH P in the Town of Carson, Wisconsin. The procurement targets geogrid materials to stabilize and reinforce the existing subgrade for a 24,580 linear foot roadway segment, which will feature a 24-foot paved surface with 3-foot Calcium Asphalt Base Course shoulders. Proposers must provide 95,600 square yards of geogrid material, accounting for required lap lengths, and submit detailed documentation including recommended geogrid brand, type, base thickness, strength, and index property units. The Request for Proposal (RFP) requires proposers to include ASTM test results, references from at least three firms with similar project experience, and pricing quoted on a per-square-yard basis covering the geogrid product, testing, and delivery. The proposal submission deadline is March 2, 2021, at 2:00 p.m., with an estimated notification of intent to award on March 15, 2021, and contract award targeted for April 1, 2021.

The RFP does not specify explicit set-aside designations or restrictions on responding organizations. Delivery of the selected geogrid product must occur by May 15, 2021, to the Portage County Highway Department facility in Plover, Wisconsin. The contract will be effective from the award date through December 31, 2021, with potential renewal options for up to three additional one-year periods by mutual agreement. Evaluation and selection will be based on submitted proposal information, references, and comprehensive cost considerations including excavation, materials, and final cross-section specifications. While no specific budget range is provided, the County reserves significant procurement flexibility, including the right to reject any or all proposals, request final offers from top scorers, negotiate contract terms, and cancel contracts for non-appropriation of funds or contractor non-compliance. The project encompasses approximately 95,600 square yards of geogrid material installation with an anticipated total project scope covering roadway reconstruction and subgrade stabilization.
