Summitville Dam - TOE SEEP MODIFICATIONS - SV-103

The Colorado Department of Public Health and Environment is soliciting competitive bids for Project SV-103, Summitville Mine Toe Seep Modifications, a construction project located at the Summitville Dam in Rio Grande County, Colorado. The procurement involves comprehensive modifications to the toe seep collection and pumpback system at the Summitville Mine Superfund Site, with work to include mobilization and demobilization, manhole dewatering operations managing up to 70 gallons per minute of acidic, heavy metal-contaminated inflow, removal and replacement of existing flow meters with new 3-inch diameter magnetic flow meters rated for 0-200 gpm, replacement of pressure transducers with units rated for 0-250 psig, replacement of float controls with submersible pressure transducers and atmospheric pressure transducers, reprogramming of the existing Panasonic Nais FP PLC-C32T2 controller for water level-based pump operation, installation of instrument data management capabilities to store six months of operational data, installation of two owner-provided Grindex Major Inox pumps, and comprehensive commissioning, testing, and startup activities including three complete operational cycles. Deliverables include detailed work plans, shop drawings, product data, manufacturer certifications, calibration reports, testing reports, Standard Operating Procedures, and Operation and Maintenance Manuals, with one day of onsite training provided to owner staff. All materials must be compatible with fluids having pH as low as 2 and high concentrations of heavy metals, with specified acceptable manufacturers including Krohne Optiflux 4000 flow meters, NOSHOK 612 series pressure transducers, and Measurement Specialties Model KPSI 320 atmospheric transducers. Bidders must demonstrate minimum qualifications by submitting documentation of successful completion of at least three similar projects within the past five years involving installation of instrumentation in water pumping systems with programmable logic controller integration, possess a valid Colorado business license, and register with the Colorado Operations Resource Engine Vendor Self Service system. Questions must be submitted by email to Sam Fuller at sam.fuller@state.co.us by May 6, 2015 at 3:00 PM, with responses provided in an addendum by May 13, 2015.

This project is restricted to bidders meeting specific qualifications and compliance requirements, with preference given to Colorado resident bidders and projects utilizing Colorado labor, with a minimum requirement that eighty percent of work be performed by Colorado residents. No explicit set-asides for disadvantaged enterprises are specified in the available documentation, though the project establishes federal minority and women business enterprise participation goals of 6.1 percent and 6.6 percent respectively due to Environmental Protection Agency funding. The project must integrate with the existing Watertronics pump station system installed at the Summitville Mine Transfer Station, including the existing Panasonic Sigma programmable logic controller, dual 9-horsepower Grindex pumps, Siemens combination motor starter, and CONERY level float control systems, requiring contractor coordination with this established infrastructure. Contractors must comply with OSHA 29 CFR 1910.120 requirements and all applicable health and safety standards, maintain performance and labor-material payment bonds, and carry comprehensive general liability insurance with limits of $2,000,000 general aggregate and $1,000,000 per occurrence. The project is estimated at $50,000 and is funded primarily through federal funds distributed by the U.S. Environmental Protection Agency, making federal requirements applicable including Davis-Bacon wage rate requirements and extensive federal financial management and audit obligations per 40 CFR 35 Subpart O. Bidders must submit a Bid Bond equal to 5 percent of the total bid amount, and the State will retain five percent retainage from progress payments until final completion and acceptance.
