The contractor shall also provide customer service, quality control, and all other services as listed herein.

2.0. OBJECTIVE - Work to be performed under the project consists of the chemical treatment of the Central Plant at the Bureau of Reclamation Lower Colorado Basin Regional Office (LCBRO).

Reclamation is seeking a comprehensive water treatment program for the Central Plant. The intent is to preserve the HVAC equipment while optimizing water and energy efficiency though proper corrosion, scale, and biological fouling control.

3.0. BACKGROUND - The worksite is located at the LCB in Boulder City, Nevada, which is approximately 24 miles southeast of Las Vegas, NV, in Clark County. The Central Plant is located at 500 Date Street, Boulder City, NV 89005.

Work that requires the plant to be taken offline will be conducted after hours or on weekends, unless requested by the Contracting Officer (CO) or the Contracting Officer’s Representative (COR).

The contractor shall perform monthly open- and closed-loop water system chemical treatment. The Central Plant is a closed-loop system comprising of two Smardt centrifugal chillers, model WA046.

The condenser is an open-loop system with two Marley cooling towers, model NC8401KAN2SGF.

The primary function of the Central Plant is to provide cool water to the air conditioning system for the Lower Colorado Green Building and the Date 100 and Date 200 buildings.

The contractor shall determine how much labor is needed to perform the tasks, what methods will be used to complete the job, and which supplies, materials, and equipment are needed.

These performance-based specifications express the Government’s requirements in the form of General Work Quality Standards (GWQS). GWQS are provided as the Government’s best gauge of the minimum quality standards to be met. The results of the work performed under this contract shall conform to the GWQS, and the Government expects that upon completion of the periodic inspection, testing, and treatment these minimum standards will be met or exceeded.

4.0. Quality Control Plan – The quality of work provided shall be of a high standard for the Central Plant water system treatment, as defined within this performance work statement.

• M-alkalinity levels will be less than 600 ppm;

• pH levels will be maintained between 8.5 and 9.2;

• Sodium Nitrite will be maintained between 950 and 1,050 ppm;

• Free and available azole 5–10 ppm;

• Iron: <1 ppm
