Troxler 3440 Legacy or InstroTek Xplorer 2 3500 Dens Gauges

The Michigan Department of Transportation (MDOT) issued Request for Proposal 26-732 on January 9, 2026, to procure five (5) surface moisture nuclear density gauges, with bidders required to submit proposals by January 23, 2026, at 3:00 p.m. Eastern Time. The solicitation specifies that vendors must provide either Troxler 3440 Legacy or InstroTek Xplorer 2 3500 density gauges, each equipped with comprehensive standard accessories including an 8-inch rod with 2-inch increments, reference standard, drill rod, rod extraction tool, scraper plate, AC and DC chargers, quick reference card, lock with two keys, operator's manual, and two extra battery packs per gauge. The contractor must accept trade-in and disposal of five existing Troxler 3440 density gauges at no cost to MDOT, with delivery expected within 90 calendar days after receipt of order to MDOT's Construction and Technology Building in Lansing, Michigan, between 8:00 a.m. and 3:30 p.m. EST. Qualified bidders must be either the actual manufacturer or authorized by the equipment manufacturer to provide service, repairs during the warranty period, and technical guidance regarding hardware and software. The procurement timeline includes bidder questions due by January 13, 2026, with responses to questions posted by January 15, 2026. All pricing must be firm for the entire contract term and submitted on Schedule B on an F.O.B. Destination basis with all-inclusive costs covering shipping, handling, and delivery. The State will award the contract to the responsive and responsible bidder with the lowest price after accounting for the trade-in allowance, with contract commencement anticipated for February 2, 2026.

The RFP does not specify any set-aside designations or restrictions on organizational types, nor does it identify incumbent vendors or current contractors beyond the requirement to accept the five existing Troxler 3440 density gauges as trade-ins. Payment will be made via Electronic Funds Transfer within 45 calendar days of invoice receipt or final acceptance of deliverables, whichever is later. The evaluation process is on a pass/fail basis, and the State reserves the right to conduct reference checks, request price concessions, and consider prior performance and economic impact to Michigan in its award decision. The RFP documentation does not provide a specific budget range or award value; however, the total contract value will depend on the number of units procured (five density gauges) and the pricing submitted by bidders on Schedule B. Interested vendors must complete the Vendor Questions Worksheet, accept or propose exceptions to the Standard Contract Terms, and submit both Schedule A (Statement of Work) and Schedule B (Pricing) with their proposals.
