The Contractor shall perform all tree work in accordance with contract specifications and the following tree care standards, latest addition, unless otherwise directed by the CO. Shrubs and trees that are acceptable candidates for planting are located in Installation Development Plan.

2 SERVICE SUMMARY

The contract service requirements are summarized in performance objectives that relate directly to mission essential items. The performance threshold briefly describes the minimally acceptable levels of service required for each requirement. The Services Summary (SS) and the contractor’s Quality Control Plan provide information on contract requirements, the expected level of contractor performance and the expected method of government validation and confirmation of services provided. These thresholds are critical to mission success. Procedures as set forth in the FAR 52.212-4 (a), Contract Terms and Conditions - Commercial Items, Inspection/Acceptance, will be used to remedy all deficiencies. During the first initial 30 days of the contract, two additional errors on each work shall be allowed in an effort to identify normal phase-in problems.

2.1 QUALITY CONTROL

The contractor 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, the American National Standards Institute (ANSI), and local Extension Offices of the Federal Cooperative Extension Service. Include the inspection system requirements of FAR 52.246-4 in this document. The contractor shall develop and implement procedures to identify, prevent, and ensure non-performance and continual repeat of defective service does not occur. A written Quality Control Plan shall be submitted to the contracting officer for review and feedback. The plan shall be submitted no later than the pre-performance conference. The plan shall specifically address the contractor’s strategy to provide quality workmanship, continual process improvement and for correcting deficiencies as required.

2.2 QUALITY ASSURANCE

The government shall inspect and evaluate the contractor’s performance to ensure services are received in accordance with requirements set forth in this contract. The CO or COR shall 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 CO or COR will use the contractor’s work schedule or modified version thereof, to record validation results. Results of the validation then become the official Air Force record of the Contractor’s performance. When a performance threshold has not been met or contractor performance has not been accomplished, the COR will initiate and provide the Contracting Officer a Contract Discrepancy Report (CDR) DD Form 2772 for issuance to the contractor. The contractor shall respond to the CDR IAW instructions provided and return it to the Contracting Officer within 1 calendar days of receipt.

2.2.1 PERIODIC VALIDATIONS

This method requires the COR to employ a “spot check” style of evaluation based on the Contractor’s schedule. Periodic validations will be conducted on a scheduled basis (daily, weekly, monthly, quarterly, semi-annual or annually) and may be adjusted, based on quality trends. Any unsatisfactory inspection (defect) result shall be recorded, and the Contractor shall re- perform the service after notification by the CO or COR. Failing to meet the performance threshold as outlined in the SS for any of these performance objectives in any (1) 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 (2) two, or more consecutive or non-consecutive months during a contract period shall constitute an immediate Progress Meeting with the Multi-functional Team. All remedies shall be in accordance with the FAR 52.212-4 (a), Contract Terms and Conditions - Commercial Items, Inspection/Acceptance.

2.2.2 PERIODIC PROGRESS MEETINGS

The CO, Functional Commander, COR, other Government personnel as appropriate, and the Contractor shall periodically meet to discuss the Contractor’s performance. The following issues shall be discussed: opportunities to improve the contract, any modifications required of the contract, unsatisfactory inspections, and trends against each performance objective observed, positive performance, and steps taken by the Contractor to prevent unsatisfactory occurrences in the future. The Contractor shall provide a summation of unsatisfactory inspections and customer complaints and provide insight into any identified trends. The CO or COR shall type up the meeting minutes. The meeting minutes shall be signed by the CO and any other signatures deemed appropriate before being distributed to the functional area and the Contractor. Should the Contractor not concur with the minutes, the Contractor shall provide a written notification to the CO identifying areas of non-concurrence for resolution.
