Work is scheduled between October 5 and November 30, 2026, with a 56-calendar-day completion window including 10 days of mobilization.

Colorado resident bidder preference and Service-Disabled Veteran-Owned Small Business (SDVOSB) certification each eligible for a 5% price preference apply. The project evaluation is lowest grand total price.
