Construction Manager at Risk (CMAR) - Nevada State Route 28 Central Corridor Safety Improvements, Shared-Use Path, and Environmental Sustainability Project (from Sand Harbor to Thunderbird Cove)

The Tahoe Transportation District is soliciting proposals from qualified general contractors to serve as Construction Manager at Risk for the Nevada State Route 28 Central Corridor Safety Improvements, Shared-Use Path, and Environmental Sustainability Project (Sand Harbor to Thunderbird Cove), with proposals due October 28, 2026 at 11:00 a.m. Pacific time and a nonmandatory pre-proposal meeting on October 6, 2026.

Proposers must be Nevada-licensed general contractors, not engineering firms. The DBE participation goal for the pre-construction services phase is zero percent. Proposers must demonstrate bonding capability up to $50 million and maintain a valid Nevada Business License. The selected contractor will perform 100 percent of pre-construction services and a minimum of 30 percent of total construction work.

The scope encompasses approximately 1.75 miles of multi-use trail (10-foot-wide pathway with 2-foot-wide shoulders) with a vertical rise of nearly 300 feet across steep slopes in forested terrain. Work includes retaining walls (soil nail walls, mechanically stabilized earth, cast-in-place concrete), potential elevated bridge segments with micropile foundations, a precast concrete box culvert, safety improvements along SR 28, and water quality enhancements. The geotechnical investigation identified granular sandy soils underlain by Cretaceous granitic bedrock, with seismic design criteria at AASHTO LRFD Seismic Zone 4 and Site Class C. Construction will occur in two seasons: May–October 2027 and May–October 2028, with completion no later than October 2031.

The estimated construction cost ranges from $30 million to $40 million. Project funding includes local, state, and federal sources administered by the Nevada Department of Transportation on behalf of the Federal Highway Administration. Prevailing wage rates per Davis-Bacon or Nevada Labor Commissioner rates, whichever is higher, apply. The pre-construction phase is anticipated to run January 2027 through February 2028.

Evaluation will be two-stage: an Evaluation Panel will score and shortlist proposals on a qualifications basis, followed by separate interview scoring and ranking. Written questions are due October 9, 2026. The Notice of Intent to Award is anticipated in January 2027, with TTD Board approval and Notice of Award in February 2027. The Construction Manager may submit construction GMP or fixed price bids no more than twice. All required forms, including Buy America and Build America certification, breach of contract and debarment certifications, organizational conflict of interest disclosure, OSHA Form 300A safety records (2022–2025), and Insurance Experience Modification ratings, must accompany the proposal. Proposals must remain open for acceptance for 180 days.
