All base agencies and Service Providers are prohibited from watering, unless a hand held hose (equipped with a shut off nozzle), bucket, timed irrigation systems or watering can is used. The Service Provider shall maintain a current detailed watering schedule to include start and duration times of automatic, portable, and manual systems.

1.1.4.2. Maintenance of Irrigation Systems. Maintain irrigation systems. Maintenance includes, but is not limited to draining and charging systems, replacing damaged or broken control devices and sprinkler heads, and repairing ruptured pipes.

Check remaining nozzle caps to assure they are snug on the nozzles and shall not blow off under pressure. Hydrants open by turning the operating mechanism in a clock-wise manner. Check the direction of the arrow stamped on the bonnet. The hydrant must be fully open when in use, and fully closed when not in use. If the fire hydrant is opened less than full open, there is a danger that the fire hydrant could blow off the end of the lateral because the weep holes shall not be completely closed which shall allow water under pressure to erode the area around the fire hydrant. Only operate with an approved fire hydrant wrench.

During the first 30 days of the contract, two additional errors on each Performance Objective shall be allowed in an effort to identify normal phase-in problems, unless the incumbent Service Provider wins new contract.

2.1. QUALITY CONTROL. THE SERVICE PROVIDER SHALL. Provide a written description of the quality control system to include identification of the commercial practices and procedures to be used, such as those of the Professional Grounds Management Society (PGMS), Tree Care Industry Association, American Society of Landscape Architects (ANSI), and local Extension Offices of the Federal Cooperative Extension Service.

A written Quality Control Plan shall be submitted to the CO for acceptance The plan shall be submitted no later than the pre-performance conference or within the first 30 days of award as determined by the CO. The plan shall specifically address the requirements of the PWS, the Service Provider’s strategy to provide quality workmanship and continual process improvement, and for correcting deficiencies as required.

2.2. QUALITY ASSURANCE. The government may inspect and evaluate the Service Provider’s performance to ensure services are received IAW requirements set forth in this contract. The CO or Government may inspect by validating actual work performance, physically checking an attribute of the completed task, checking a management information report, investigating customer complaints, conferring with facility managers, or otherwise inspecting the task or its results to determine whether or not performance meets the standards contained in this PWS. The COR will use the Service Provider’s work schedule to conduct surveillance. Results of the surveillance then become the official Air Force record of the Service Provider’s performance.

Failing to meet the performance threshold as outlined in the SS for any of these Performance Objectives in any one month period shall result in a warning or letter of concern from the CO. Failing to meet the Performance Threshold as outlined in the SS of these Performance Objectives in any combination for any two, or more consecutive or non- consecutive months during a contract period shall constitute an immediate Progress Meeting with the Multi-functional Team.

2.3.1.1. Periodic Assessment Failure and Contract Reduction. Reperformance is the preferred corrective action, however, in the event the Service Provider fails to re-perform within the allotted time or at the discretion of the CO, exceeds a SS “VALID” threshold, the COR shall calculate a monthly contract deduction for each CAR exceeding the threshold and submit to CO for final approval. When approved, COR shall deduct amount from applicable contract line item from monthly invoice. Amount to be withheld shall be computed as follows:

Price per acre x Zone acreage = Monthly Deduction Cost
