About this file
This is a Sole Source Form from the County's General Services Administration for a contract with NALCO COMPANY LLC, seeking authorization for preventative maintenance services for a proprietary 3D TRASAR system used in HVAC condenser water and closed loop water systems. The contract is for a three-year period from September 19, 2023, through September 30, 2025, with an estimated expenditure of $67,958.35 for the fiscal/contract year, not to exceed $150,000. The 3D TRASAR system has been installed in County buildings since late 1998 and utilizes specific equipment, chemistry, and application methods that are exclusively produced by NALCO.
The sole source justification is based on the proprietary nature of the technology, which is protected under US Patent 6,369,894. The county determines it would be cost-prohibitive to change the systems in all county-owned closed loop water systems, and the product is recommended by leading HVAC manufacturers. The contract includes a revision to extend the sole source for an additional three years through September 29, 2028, with an increased estimated expenditure amount of $150,000. The procurement process involves approval from the Procurement Analyst and Procurement Official, with the contract managed by the General Services Department under the General Services Administration division.
