PERFORMANCE-BASED WORK STATEMENT (PWS)

FOR

WATER CHEMICAL TREATMENT FOR CLOSED & OPEN LOOP SYSTEMS

AT

PETERSON AIR FORCE BASE

2 MAY 18

SECTION I

1. DESCRIPTION OF SERVICES: The contractor shall provide all labor, equipment, tools, material, supervision, and all other necessary items to provide water chemical treatment on designated Heating, Ventilation, & Air Conditioning (HVAC) cooling and heating closed loop and open loop systems on Peterson Air Force Base (AFB), Colorado. The Government will provide the necessary chemicals for water treatment and glycol.

1.1 MAINTENANCE SERVICES: The contractor shall provide water chemical treatment and maintenance on designated HVAC cooling and heating closed and open loop systems on PAFB. The goal of this treatment is to protect Peterson Air Force Base’s chilled water loops and heated loops from a shortened life span due to excess corrosion and to prevent scale (build up) deposition in the systems. This will aid in efficient operation to maximize energy and water cost. Systems to be treated are listed in Appendix A.

1.2 Twice per year each closed loop chilled water and heating water system will be inspected, tested and treated.

1.2.1 The contract shall submit a schedule of the work 2 weeks prior to starting each round of testing. Electronic copies shall be sent to 21 CES HVAC shop and the Contracting Officer.

1.2.2 The contractor shall inspect the system for leaks and note deficiencies. The contractor shall flush sample point for approximately 10 seconds and then take a sample of system. The contractor shall check the glycol level, pH, alkalinity, calcium hardness, product level and general bacteriological level.

Based upon water quality testing levels, the water shall be bled off and chemical added to bring desired changes to water quality. If necessary, the contractor shall conduct and record follow up testing to get system within parameters. All measurements and adjustments shall be documented on a worksheet and submitted electronically to 21 CES HVAC shop and Contracting Officer within five working days.

1.2.3 Contractor shall clean and passivate the closed loop systems on an as needed basis during the contract period. Contractor shall use government provided alkaline cleaner (formula 248-L) and inhibitor (formula 1012-L) for use with cleaning process. Any additional chemicals for flushing shall be provided by contractor. As any systems are undetermined and unfunded, this is a separate line item and would require approval from the Contracting

Officer.

1.2.4 Most systems presently have by-pass feeders installed to facilitate the addition of chemicals. Where by-pass feeders are not installed, the contractor shall use their portable feeder or chemical pump to transfer the chemicals into the system. The contractor shall notify HVAC personnel if there is any need of a shutdown, of heating or cooling equipment, for the purpose of treatment with chemicals.

1.2.5 During testing if a system leakage is discovered, the contractor shall immediately contact the HVAC shop at 719-556-1822 so the HVAC shop can make the necessary repairs.

1.3 There are five (5) open loop condenser water systems on base including one (1) in Buildings 1, 1470 and 1844 and two (2) in Building 2025. These condenser water systems shall be shall be inspected, tested and their treatment shall be adjusted monthly.

This schedule shall be coordinated with HVAC Shop two weeks prior to start of work to coordinate secure access.

1.3.1 The contractor shall inspect the system for leaks and note deficiencies. The contractor shall flush sample point for approximately 10 seconds and then take a sample of the system. The contractor shall check glycol level, pH, alkalinity, calcium hardness, oxidation reduction potential (ORP), chloride, product level and general bacteriological level. Based upon water quality testing levels, the chemical feed system shall be adjusted to bring desired changes to water quality. All measurements and changes will be documented on a worksheet and submitted electronically to 21 CES HVAC shop and Contracting Officer within five working days.

1.3.2 Most systems presently have by-pass feeders installed to facilitate the addition of chemicals. Where by-pass feeders are not installed, the contractor shall use their portable feeder or chemical pump to transfer the chemicals into the system. The contractor shall notify HVAC personnel if there is any need of a shutdown of the systems for the purpose of treatment with chemicals.

1.3.3 During testing if a system leakage is discovered, the contractor shall immediately contact the HVAC shop at 719-556-1822 so they can make the necessary repairs to prevent a continuous stream of hardness minerals and dirt from entering the system.

1.3.4 Bldg 1470 Cooling Tower on Roof – In addition to regular inspection of system, contractor shall provide cleaning and treatment of cooling tower annually. Contractor shall coordinate work including any system downtime with HVAC Shop. Contractor shall clean sediment out of cooling tower.

Following cleaning and to eliminate micro-biological growth, contractor shall provide a treatment to the condensing water in tower with approximately 5 gallons of dispersion chemical. Contractor shall use their own dispersion chemical that complies with system specifications.

1.4 The contractor will comply with the NSPC (National Standard Plumbing Code), NEC

(National Electrical Code), Heating Ventilation Air Conditioning standards, and Occupational Safety and Health Administration standards (OSHA).

The contractor shall also maintain all appropriate MSDS’s (Material Safety Data Sheets) with any chemicals that are being used.

1.6 The contractor shall provide a four (4) hour knowledge based training sessions on water treatment to 21st Civil Engineering Squadron HVAC Shop twice (2) per year. Training at a minimum shall include water treatment basics to include, corrosion control, chemical inhibitors, biocides and cleaners and any other training necessary for basic understanding of water treatment. Training will be conducted in the HVAC Shop to approximately 15 personnel. The contractor shall submit training date requests a minimum of one week in advance of the projected training.
