On-Call Environmental Construction Consulting Services

The County of Sacramento's Department of Waste Management and Recycling is soliciting proposals for on-call environmental construction consulting services to support design, environmental protection, and documentation for environmental remediation and monitoring facilities at three county landfills: Kiefer, Elk Grove, and Grand Island. The primary service areas include groundwater monitoring and extraction well consulting (40% of contract), permitting support and treatment facility design for contaminated water (40%), and additional construction support (20%). Required consulting services encompass biological surveys, geological logging, well design, pumping tests, and facility design and operational procedures. The county specifically requires consultant staff to include a registered geologist or civil engineer with hydrogeological expertise, a staff biologist, and an electrical engineer. Proposals must be submitted electronically via the OpenGov Procurement portal by 4:00 p.m. on January 16, 2026, with questions due by January 2, 2026, and clarification responses provided by January 9, 2026. The evaluation criteria will assess the quality of proposed services, staff experience and qualifications, proposal compliance with format requirements, acceptance of county terms, and overall cost.

The solicitation does not explicitly mention set-aside designations or restrictions for disadvantaged enterprises. The initial contract term is 24 months, starting from an anticipated November 1, 2025 commencement, with options to extend for up to three additional one-year terms upon mutual agreement. Proposers must submit comprehensive rate sheets reflecting labor and expense costs, including effective dates and markups for materials and equipment rentals. Proposals are limited to 10 pages and must include a cover letter, company profile, service delivery plan, key staff resumes, relevant experience narrative, three references, and rate sheets. Contractors must certify independent contractor status (requiring five or more full-time employees) and comply with child support and employment reporting requirements. While specific budget ranges are not detailed, the county reserves the right to award multiple contracts and maintains broad discretionary powers in the procurement process, including rejecting proposals, negotiating terms, and waiving irregularities.
