The contractor shall maintain detailed records of the results of all inspection checks and chemical treatments to include: building number and system, date chemicals were applied, description of chemicals used, quantity of chemicals used per system to maintain standards, chemical level readings (Conductivity (TDS), Cycles of Concentration, Total Chlorine, and Nitrate) in system before and after adjustments, date of inspection check and adjustment, and name of person(s) performing the inspections and/or adjustments. This information shall be provided to the Government acceptor in writing within five (5) working days of each inspection check. The actual dispensing of chemicals into the circulated systems, by either the contractor or Government forces, will be at the discretion of the appropriate Government acceptor. Additionally, adjustments to other water quality controls such as, blowdown, water softener, etc. will also be at the discretion of the appropriate Government acceptor. Cleaning of closed loop circulated water systems will be coordinated with the Government acceptor. The contractor shall sample and test existing systems, make recommendations for water treatment chemicals, monitor cleaning chemical levels, dispose of waste liquids appropriately, and make recommendations for chemical levels to maintain optimum system performance. The circulated systems to be treated can be found in Technical Exhibit 1 (TE1).

2.1.0.12 CONTRACTOR LIABILITY: The contractor shall be liable for any physical damage caused by negligence of his/her personnel or improper chemical treatment. The contractor shall reimburse the Government for all costs associated with the repairs directly associated with damage caused by his/her personnel or faulty water treatment.

The following procedure shall determine liability for water treatment problems:

a. Pre-existing Conditions.

(1) During the non-heating season, steam boilers that operate at greater than 15 psig and hot water boilers that operate at greater than 2500F will be opened for inspection. This normally occurs once a year, during the summer months.

However, this may occur during the heating season if there is a severe problem. If the boiler inspection does not reveal any water treatment problem such as scale buildup or corrosion, then the contractor's liability would begin at that point. If a boiler inspection reveals a scale or corrosion problem, then the contractor shall determine the cause of the problem and make recommendations to the operating staff to clean and return the boiler to the proper condition. The contractor shall be liable once the cleaning treatment begins. Boilers that are not opened shall receive water treatment, however, the contractor will not be held liable for any pre-existing water treatment problems until a visual inspection of the interior is performed.

(2) Cooling systems will be inspected during the non-cooling season. As described above for heating systems, if a cooling system fails inspection, the contractor shall determine the cause of the problem and make recommendations to the operating staff to clean and remedy the condition.

The contractor shall be liable once the cleaning treatment begins. Additionally, if a unit is not physically opened for visual inspection but runs efficiently during the air conditioning season without high head pressure problems and performs according to design specifications, then the unit can be assumed to be clean, and the contractor's liability shall begin with normal treatment. However, if a cooling system is not running efficiently, or has high head pressure problems, the contractor shall begin treatment, but will not be held liable for any pre-existing water treatment problems until a visual inspection of the interior is performed.

(3) Once the contractor's treatment program is begun, on a heating or cooling system, if a piece of equipment is taken out of service due to a water treatment related problem, that can be directly attributed to the contractor's action or inaction, then the contractor shall be liable for the damage. Additionally, the Contracting Office will decide if the cause of the problem should be considered as grounds for termination for default.

b. Operational Problems:

(1) If the Government follows the contractor's recommended dosing, blow-down, etc. and control parameters are not maintained, the contractor shall be responsible. The Government shall maintain a log of actions taken to document compliance with the contractor's plan.

(2) If the Government does not follow the contractor's recommendations, then the contractor will not be held responsible.

(3) If the contractor does the actual dispensing, blow-down, adjustments to controls, etc., and control parameters are not maintained, then he/she will be responsible.

2.1.0.13 TRAINING. The contractor shall conduct annual water treatment training session of no more than four (4) hours for the Government staff. This will occur on site at a government provided location. Subject matter, dates, time, and location shall be coordinated with the Government acceptor.

2.1.0.14 BUSINESS REVIEW. The contractor shall conduct a business review briefing for the Government on an annual basis. This briefing shall include a report of the amount and cost of each chemical used during the contract period as well as the overall contract cost. It shall address any outstanding issues concerning ordering, delivery, invoicing, or payment. Specific sites where problems are occurring shall be discussed. Energy efficiency and cost savings opportunities shall be addressed. The contractor shall make recommendations for improvements to the water treatment program during the review.

2.1.0.15 REVIEW OF FACILITY PROJECTS. The contractor shall review engineering plans and specifications of new construction or renovation projects on APG. Specifically, the contractor shall make recommendations in writing about the piping, equipment, and controls proposed for water treatment.

2.1.0.16 ORDERING PROCEDURES.

a. The funding of the base year and exercising the option years will initiate the ordering for chemicals of the quantities needed, the delivery destination and the required delivery date. The Government acceptor will be the primary POC for this contract. Deliveries of chemicals will be coordinated between contractor and

b. The unit prices offered by the contractor for individual chemicals are firm-fixed price. The contractor shall be paid based on actual quantities delivered plus or minus 10% per FAR Clause 52.211-16, Variation in Quantity.

c. The contractor shall not exceed the total value of the contract without a modification signed by the Contracting Officer except as authorized by FAR Clause 52.211-16, Variation in Quantity. No one other than the Contracting Officer has the authority to alter the specified quantities or increase the total value of the contract. The contractor shall keep account of all quantities delivered and shall immediately notify the Contracting Officer if unauthorized Government personnel has requested delivery of quantities more than the quantities specified in the contract. Failure to follow these procedures will result in non-payment of excess quantities delivered.

2.1.1 Non-Personal Services. The personnel rendering the services are not subject; either by the contract’s terms or by the manner of its administration, to the supervision and control usually prevailing in relationships between the Government and its employees. Non-personal service contracts are authorized by the Government in accordance with (IAW) Federal Acquisition Regulation (FAR) Subpart 37.104, under general contracting authority, and do not require specific statutory authorization.
