Independent Cost Estimating and Review Services

The City of Aurora, Colorado is seeking independent cost estimating and review services for a major infrastructure project. The underlying construction project addresses the installation of a new storm sewer and outfall, which requires trenchless technology to cross Colfax Avenue, along with inlets, laterals, and the relocation of wet utilities. The selected estimator will review plans that involve deep trenching, low vibration shoring, soil disposal, groundwater dewatering, and potential groundwater treatment for approximately 3,500 linear feet of large diameter or box storm sewer. The scope of the construction project also encompasses custom drainage structures, access manholes, headwall and wingwall structures, and coordination with dry utilities. The project requires restoring pavement, landscaping, sidewalks, curbs, gutters, and other damaged areas to equal or better condition. For the segment between 14th Avenue and the Westerly Creek outfall, environmental screenings indicate the presence of hydrocarbons and historic landfill conditions, necessitating special soil handling, gas monitoring, ventilation, and remediation. Eligibility for this opportunity is restricted to onshore organizations based in the United States. The agency is currently looking for proposals to establish the budget for these services, and bidders must submit their responses digitally via email or online. The agency has scheduled a pre-bid meeting for June 3, 2026, and requires all questions regarding the solicitation to be submitted no later than June 10, 2026.
