2.0. Services summary (SS)

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 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 surveillance and confirmation of services provided. These thresholds are critical to mission success. Procedures as set forth in the Federal Acquisition Regulation (FAR) 52.212-4 (a), Contract Terms and Conditions - Commercial Items, Inspection/Acceptance, will be used to remedy all deficiencies. During the first initial thirty (30) days of the contract, two (2) additional errors on each task shall be allowed in an effort to identify normal phase-in problems. The absence of any contract requirements from the SS shall not detract from its enforceability nor limit the rights or remedies of the government under any other provision of the contract, including the clauses entitled “Inspection of Services” and “Default.” The government has the right to inspect all services required in the contract.

2.1. PERFORMANCE EVALUATION. The purpose of the Services Summary is to define performance evaluation and payment procedures. The Performance Objective (column 1) describes what the government will survey. Performance of a service will be evaluated to determine whether or not it meets the Performance Threshold (PT) of the contract. When the PT is exceeded, the QAP will document the file with a Corrective Action Report (CAR) or a Performance Assessment Report (PAR) and forward these documents to the Contracting Officer for his determination if further action is necessary.

2.1.1. The government will periodically evaluate the contractor’s performance by appointing a representative(s) to monitor performance to ensure services are received. The government representative will evaluate the contractor’s performance through inspections of reports and contractor services documentation. The government may inspect each task as completed or increase the number of quality assurance inspections if deemed appropriate because of repeated failures or because of repeated customer complaints. Likewise, the government may decrease the number of quality assurance inspections if performance dictates. The government COR will make final determination of the validity of customer complaint(s).

2.1.2. If any of the services do not conform to contract requirements, the government may require the contractor to perform the services again in conformity with contract requirements at no increase in contract amount. When the defects in services cannot be corrected by re-performance, the government may:

2.1.2.1. Require the contractor to take necessary action to ensure that future performance conforms to contract requirements; and

2.1.2.2. Reduce the contract price to reflect the reduced value of the services performed.

2.2. Quality Control. The contractor shall develop and maintain a quality control program to ensure services are performed in accordance with this contract and PWS. The contractor shall develop and implement procedures to identify and prevent non-performance and continual repeat of defective service. A written Quality Control Plan shall be submitted to the contracting officer for review and feedback. The plan shall be submitted no later than 10 working days after award. The plan shall specifically address the contractor’s strategy to provide quality workmanship, continual process improvement and for correcting deficiencies as required.

2.3. 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 COR shall inspect by watching actual task 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 record surveillance results. Results of the surveillance 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) for issuance to the contractor. The contractor shall respond to the CDR IAW instructions provided and return it to the Contracting Officer within 10 calendar days of receipt.

2.4. Surveillance Methods.

2.4.1. Periodic Surveillances. This method requires the COR to employ a “spot check” style of evaluation based on the contractor’s schedule. Periodic surveillances 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 COR.

2.4.2. Customer Complaint. This method requires the customer to fill out a locally generated form provided by the COR or Contracting Officer. The COR will verify the complaint and notify the contractor of valid complaints. The contractor shall acknowledge the complaint within 2 hours and inform the COR of his recommendation. Any deficiency shall be documented and the contractor shall re-perform service immediately, if appropriate, or within 24 hours at no increase in contract amount. The contractor shall respond to the Customer Complaint in accordance with the instructions provided and return it to the Contracting Office within 5 calendar days of receipt. Any unsatisfactory inspection identified but re-performed acceptably shall still be counted as an unsatisfactory inspection.

2.4.2.1. 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 Contracting Officer.

2.4.2.2. 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. All remedies shall be in accordance with the FAR 52.212-4 (a), Contract Terms and Conditions - Commercial Items, Inspection/Acceptance.

2.5. Periodic Progress Meetings. The Contracting Officer, 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.

2.5.1.The minutes of these meetings will be reduced to writing, signed by the Contracting Officer and any other signatures as deemed appropriate, distributed to the functional area and the contractor. Should the contractor not concur with the minutes, the contractor will provide a written notification to the Contracting Office identifying areas of non-concurrence for resolution.
