About this opportunity
Alaska Railroad Corporation is requesting sealed bids on Bridge 158.7 Replacement construction at Milepost 158.7 near Cottonwood Creek in Wasilla under ITB 26-23-214657, with proposals due June 30, 2026 at 3:00 p.m. and a non-mandatory site visit scheduled for June 23, 2026 at 12:00 p.m. at the Wasilla Section House. The project is funded jointly by ARRC and the Federal Transit Administration, triggering all federal contract compliance requirements for projects exceeding $100,000 and a race-neutral DBE aspiration of 4.0% participation during fiscal years 2025–2027.
The scope involves complete replacement of an existing six-span timber bridge with a new two-span precast concrete ballast deck bridge on steel pipe piles, including sheet pile abutments, reinforced concrete pile caps, bulkhead and riprap installation, track work, and site restoration. Estimated line-item quantities include 2.55 acres of clearing and grubbing, 4 precast concrete half-span units (furnished by ARRC from the Anchorage warehouse), 3 pile caps, 21 structural steel pipe piles (12-inch and 24-inch diameter), 58 structural steel sheet piles and soldier piles, 318 cubic yards of Class II riprap, and 256 linear feet of track surfacing and tamping. Bridge design complies with Cooper E-80 live loads, 0.25 coefficient seismic parameters, 200 PSI ice pressure loads, and ARRC 2025 Standard Specifications and AREMA standards. All structural steel must be hot-dip galvanized per ASTM A123 (2.3 ounces per square foot); prestressed concrete must achieve 6,000 PSI at 28 days; and field welding must use SMAW or FCAW processes with specified electrode grades.
Substantial completion is required by January 30, 2027; final completion by June 30, 2027. Liquidated damages of $4,900 per calendar day apply for failure to achieve substantial completion. Bidders must submit a bid bond (5% of bid price), construction bid form, contractor responsibility questionnaire, cost schedule, and — if apparent low bidder — subcontractor list, quality assurance/quality control plan, and site health and safety plan within five working days of notification. The successful contractor must provide 100% performance and payment bonds and a certificate of insurance prior to award. Prevailing wage requirements per the Minimum Rates of Pay for Laborers and Mechanics effective April 1, 2026 apply. Contractors must register with Avetta for verification and submit weekly certified payrolls within seven days of each pay period.
