Y--YOSE 215363 - Replace Tuolumne Meadows Wastewater Treatment Plant, at Yosemite National Park in California.

The contract under solicitation number 140P2026R0001 entails the complete replacement of the obsolete Tuolumne Meadows Wastewater Treatment Plant within Yosemite National Park, California, with a projected period of performance extending from June 3, 2025, to June 30, 2033. The project is a high-complexity construction effort involving the demolition of existing infrastructure including sewage ponds, effluent spray fields, access roads, and utility lines, followed by the installation of new wastewater treatment systems compliant with rigorous technical specifications across Divisions 01 through 46. The scope includes civil work, paving, landscaping, electrical distribution, substation systems, surge protection, temporary power, and comprehensive testing, commissioning, and training. All work must adhere to stringent quality standards referencing the International Building Code, ASTM, NFPA, NECA, and other industry specifications, with inspections required at both manufacturer facilities and the project site. Final acceptance occurs only after successful on-site performance demonstrations and compliance with all contractual requirements. The solicitation is structured as a sealed bid under full and open competition with an estimated construction magnitude exceeding $10 million, evaluated using a best value tradeoff process where non-price factors significantly outweigh pricing. Evaluation hinges on five primary technical criteria—Technical Approach, Project Experience, Past Performance, Schedule, and Key Personnel—with Small Business Participation also assessed. Key personnel must include a Project Executive, Manager, Superintendent, Quality Control Manager, and Safety Manager, with substitution rules tightly constrained, especially in the first 90 days of performance. Compliance with federal regulations is exhaustive, incorporating FAR clauses covering business ethics, anti-kickback provisions, labor standards per Wage Determination CA20250018, and personal identity verification. Contractors must submit electronic proposals in two volumes, each under strict file size limits, with all submissions via email to the Contracting Officer. Invoicing must occur exclusively through the Invoice Processing Platform, not WAWF, and the government retains final authority for inspection and acceptance. Special requirements mandate the use of designated staging areas with strict restoration protocols, prohibit concrete batch plants in sensitive zones, and allow unilateral exercise of options within 120 days of award. Offerors are required to submit past performance questionnaires, project experience details, general references, and a small business subcontracting plan consistent with FAR 52.219-9, alongside current SAM registrations and socioeconomic certifications.
