1.0 Purpose

The purpose of this SOW is to obtain trails maintenance services at Allegheny National Forest by means of a combination firm fixed-price and indefinite quantity contract.

1.1 General Requirements

The Contractor must furnish all labor, supervision, equipment, and materials necessary to provide trails maintenance services in accordance with the requirements specified herein. The operations to be performed must include normal tread maintenance, heavy tread maintenance, additional appurtenant trail materials (AASHTO #8, AASHTO #10, DSA Limestone, PA2A, PA3A, PA3A Limestone), obliteration of abandoned/unauthorized trail (backfilling any trenches, holes, pits), hazard tree removal, seeding, mulching, silt fencing, Riprap (R-3, R-4, R-5), collection and disposal of litter and trash, vegetation cutting and removal, underbrushing, erosion control, ditch cleaning, and other miscellaneous services as described herein.

910 The Forest Service (FS) has a need for a Performance Based Service Contract for Forest-Wide Trail Normal and Heavy Maintenance on the Allegheny National Forest. The contractor(s) shall provide all expertise, labor, supervision, services, equipment, tools, supplies, permits (when and if required), coordination with utilities, transportation, and incidentals necessary to perform trail normal and heavy tread maintenance, directly related to trail activities on the Allegheny National Forest in Pennsylvania.

Such normal and heavy tread trail maintenance will occur primarily occur in the Spring and Fall seasonal months. Spring and Fall maintenance performance will be optional for any given year during the term of the contract depending on the condition of each trail system listed in the contract. This will depend on the condition of each trail system that may be affected by adverse weather conditions and or use. Spring maintenance will start March 1st and must be completed no later than the Thursday before Memorial Day. If start up or other scheduled work days are late/postponed due to weather, trail conditions or other extenuating circumstances defined by the CO or COR – work may continue after the trail is open an equal number of days upon approval the of CO or COR. Fall maintenance on trails will start Tuesday after Labor Day and be completed no later than December 15th. If start up or other scheduled work days are late/postponed due to weather, trail conditions or other extenuating circumstances defined by the CO or COR – work may continue after 15 December for an equal number of days upon approval the of CO or COR. Trails will remain open during the contract, unless agreed to by the FS that a section may be closed for safety or resource protection. No evening work or work on weekends or federal holidays will be allowed without approval of the Contracting Officer’s Representative. Work will only be allowed during appropriate weather conditions. Inspections will be performed weekly and work will be accepted prior to contractor shutting down for the weekend.

91106.1 Normal Trail Maintenance (aka, Normal Tread Maintenance) will primarily include the maintenance of existing trails with not more than 6” deep ruts or holes from the tread surface for no longer than 500 foot sections ending with a trail tread depth of 4” of compacted aggregate, and a trail width of 50-64”. Reconditioning of the trail surface may include the maintenance of any or all trail tread, including pulling in material from undesirable berms and reincorporating into tread, compacting and correcting damage that corrupts drainage pattern. The work will include reshaping the trail to the original insloped / outsloped condition and controlling surface drainage to prevent further degradation of the trail and compact all disturbed areas. All dips will be reconstructed as shown in the drawings. Culvert maintenance by cleaning culverts of deposited/debris materials to allow free flow of water. Ditch maintenance including removal of deposited/debris materials to allow free flow of water while maintaining depth and slope. Drain Dip maintenance ensuring leadoff ditches be opened and free of deposited/debris materials and compaction of materials to maintain side slope stability. Loading, unloading and transportation of government furnished materials to a trail location determined by the COR. Additional surface aggregate may be needed to supplement pulled-in slough material that is recaptured, watered (as determined by the COR) and compacted within specifications and tolerances. Such surfacing aggregate will include:

AASHTO #10 or #8, DSA Limestone, PA 2A, AASHTO #3 (PA 3A), AASHTO #3 Limestone (PA 3A Limestone) Government furnished surfacing aggregate, The FS estimates at least an annual need of approximately 100 tons of the above aggregates for each trail system (5 trail systems, i.e., 500 tons minimally) Task Orders under this section will specify types of aggregate surfacing to be applied.

91106.1 Heavy Trail Maintenance (aka, Heavy Tread Maintenance) will primarily include those portions of heavily damaged trail tread that would require more than normal maintenance to return to original shape. Heavy maintenance will include areas that are deeply rutted, have large waterholes and drainage has been significantly changed and where more than normal amount of work is needed to repair. In all cases the trail is still defined but has significant reshaping to be performed. Heavy Tread maintenance will be required if ruts/holes are deeper than 6” but not more than 18” and less than 30 CY of material needs to be moved over a 150’ length of trail ending with a trail tread depth of 4” of compacted aggregate, and a trail width of 50-64”. Specifically, heavy tread trail maintenance will include: Removal and reshaping berms as needed, pulling in material from undesirable berms and reincorporating into tread and compacting, correcting damage that corrupts drainage patterns, reshaping the trail to the original insloped/outsloped condition and controlling surface drainage to prevent further degradation of the trail. All dips will be reconstructed as shown in the drawings. Additional surface aggregate may be needed to supplement pulled-in slough material that is recaptured, watered (as determined by the COR) and compacted within specifications and tolerances. Such surfacing aggregate will include:

The FS estimates at least an annual need of approximately 100 tons of the above aggregates for each trail system (5 trail systems, i.e., 500 tons minimally) Task Orders under this section will specify types of aggregate surfacing to be applied.

920 Additional appurtenant trail structures shall be maintained within NORMAL and HEAVY tread trail maintenance pay item and may include in each task order the following additional requests separately priced:

920.1 AASHTO #8,

920.2 AASHTO #10
