1.3.1 MOW

Grass and weeds shall be maintained between 7 to 14 inches when measured from the ground to the highest point on the plant. Note: “vegetative cover” includes any and all plant species found on the airfield. All vegetative cover shall not be shorter than 7 inches in height to prevent dust and debris on the airfield and shall not exceed 14 inches in height. Vegetative cover over 14 inches will attract ground nesting birds as well as provide cover and food for rodents, birds, and larger animals such as deer, turkey and coyotes. Approved plant growth regulators may be used to reduce mowing frequency and must have approval prior to use and must be applied according to the label directions. The use of growth regulators does not relieve the contractor of the requirement to maintain the vegetative cover at the contract height. The contractor shall begin mowing operations at the active runway paved surface and move away from active runway to the outermost area. This causes insects and animals to move away from the runway. The contractor shall be responsible for insuring that all foreign objects and debris produced by grounds maintenance is cleared off all taxiways, and aircraft parking aprons before leaving the work area. Any vegetative cover in drainage ditches on the airfield must also be maintained between 7 to 14 inches and may also be treated with an approved Aquatic herbicide by an applicator with a State of Delaware category 5A Aquatics category certification. The contractor will not operate equipment in or near drainages such that ruts, bare areas or runoff is created. If grounds near drainages are too saturated to operate standard mowing equipment, the contractor will employ alternate, low impact techniques such as boom-type mowers or string trimmers. In the event of heavy rainfall, the contractor must avoid mowing saturated soils if doing so would cause rutting or excessive soil compaction. If saturated areas are encountered, the contractor will notify Airfield Management and the COR in writing which areas were deliberately skipped and when re-evaluation will occur. Although rain delays are inevitable, the contractor must be prepared to increase the number, duration, and/or frequency of mowers on the airfield to rapidly correct noncompliant areas once conditions permit if any previously saturated areas have grown out of limits as this poses a significant risk to aviation safety. Requirements and standards for maintaining grounds in areas identified as BASH is reflective in AFI91-212, Bird/Wildlife Aircraft Strike Hazard

(BASH) Management Program, dated 31 May 2018.

1.3.2 AIRFIELD LIGHT FIXTURES AND NAVAIDS

In addition, vegetative cover is not to exceed 7 inches within 10 feet surrounding all airfield navigation aids or visual aids or visual navigation facilities

(e.g. instrument landing system, tactical air navigation, lighting, signage, etc.) regardless of their location within the Aircraft Movement Area. Dover AFB has a TACAN and an Instrument Landing System (ILS). IAW DAFBI

13-204, dated 23 September 2020, the area around the TACAN Antenna should be clear and reasonably smooth.

Clusters of small trees, dense vegetation and shrubs are not allowed within 1,000 feet of the facility. For the

(ILS), the 436 OG/CC will identify precision approach critical areas on an airfield diagram in the base airfield operations instruction. Area(s) shall be defined to include the dimensions of the area to be protected. IAW FAAO

6750.16C and 6750.49A, vegetation growth shall not be permitted to exceed 12 inches in height in the ILS critical areas within 2,000 feet of the localizer and 800 feet from the glide slope antennas. The identified areas for the

TACAN and ILS systems will be identified on Appendix B-1.

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, one additional error on each service summary performance objective shall be allowed in an effort to identify normal phase-in problems.

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.

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 Letter of Concern for issuance to the contractor. The contractor shall respond to the Letter of Concern

IAW instructions provided and return it to the Contracting Officer within 1 calendar days of receipt.

2.3 PERFORMANCE ASSESSMENT

2.3.1 PERIODIC VALIDATIONS

This method requires the COR to employ a “spot check” style of evaluation. 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. All inspections shall be recorded on a Performance Assessment Report (PAR) and issued to the contractor. The contractor shall re-perform any defects identified in the PAR in accordance with the

Service Summary. Failing to meet the performance threshold as outlined in the SDS 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 SDS 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.

2.4 PERIODIC PROGRESS MEETINGS

- Any modifications required of the contract

- Unsatisfactory inspections and trends against each performance objective observed

- Positive performance

- Steps taken by the Contractor to prevent unsatisfactory occurrences in the future.

The host of the meeting will produce written meeting minutes and distribute to all parties in attendance.
