Shoulder Widening & Install Rumble Strips

The Arizona Department of Transportation (ADOT) is soliciting bids for shoulder widening and centerline and edge line rumble strip installation on two Yuma County projects, with proposals due October 23, 2026. Bidders must be prequalified with ADOT and registered on the project Plansholder List as a Prime contractor to submit valid bids, and all contractors must be licensed under Arizona Revised Statutes 32-1101 through 32-1170.03.

Scope covers Project 0000 YU YYU T0437 01C on Avenue G between County 11th Street and County 16th Street, and Project 0000 YU YYU T0439 01C on Avenue B between County 18th Street and SR 195. Work includes shoulder widening, rumble strips, signing, pavement marking, and related work. Electronic bidding through Bid Express is mandatory and requires a Digital ID and the project EBSX file. Questions must be submitted through Bid Express, and questions submitted less than three working days before bid opening may not be answered.

The combined contract is programmed at $8.17 million with a 190 working-day completion timeline. The proposal guaranty is 10 percent of the bid amount, submitted through approved surety companies. The awardee must execute a Performance Bond and Payment Bond, each at 100 percent of the bid amount, along with an insurance certificate and contract agreement. Avenue B work must begin immediately upon contract commencement, while Avenue G work cannot begin until after April 1, 2027.

During the Disadvantaged Business Enterprise (DBE) program transition period, ADOT may not set DBE contract goals or count DBE participation toward overall goals. Contractors are encouraged to use DBE-neutral efforts and must maintain tracking records. Federal requirements include Title VI, wage determination, and erosion control, stormwater quality, and permanent stabilization measures.

The bid book lists bid opening as September 11, 2026, at 11:00 a.m. (M.S.T.), which conflicts with the October 23, 2026 due date.
