SPECIFICATIONS, AND DRAWINGS

A. ROAD MAINTENANCE

Contractor shall maintain roads, commensurate with Contractor’s use, in accordance with Road Maintenance Requirements in H.27, Appendix B K-F.3.1# and the Road Maintenance Specifications. Performance of road maintenance work by Contractor may be required prior to, during, or after each period of use. Forest Service will do required pre-haul maintenance or pay contractor to do required pre-haul road maintenance at the rates listed in H.27. Contractor will be responsible for maintaining all roads during haul and post haul with no compensation by the Forest Service. The timing of work accomplishment shall be based on Contractor’s Operating Schedule.

When two or more commercial users are simultaneously using the same road where Forest Service is not requiring maintenance deposits, the commercial users will develop maintenance responsibilities and arrangements for accomplishing the work. Forest Service must agree to this plan. If the commercial users cannot agree on maintenance responsibilities, Forest Service shall resolve the differences.

Unless agreed in writing, pre-haul maintenance shall be completed on any portion of road prior to hauling on that portion. Maintenance, as used in this contract, does not include road reconstruction or repairs of an extraordinary nature.

Definitions and specifications for required Road Maintenance Items (Appendix B K-F.3.1# and H.27) are as follows.

RECONSTRUCTION, AND EROSION CONTROL

Description

1.1. Work. Construct and reconstruct temporary roads as SHOWN ON THE DRAWINGS.

Perform clearing and grubbing, excavation and embankment, and erosion control. During clearing and grubbing, treat merchantable timber, down material, and construction slash, including all vegetation within the clearing limits. During excavation and embankment, excavate and place soil and rocky material; shape the roadway, including approaches, turnouts, turnarounds, and drainage dips; and place all excavated materials, regardless of nature. Install stream crossing CMP with dimensions of diameter and length and at locations as STAKED ON THE GROUND. Perform erosion control by installing grade dips. Construct the roadway in conformance with the dimensions SHOWN ON THE DRAWINGS or designated on the ground.

Materials

1.2. Requirements. Ensure that materials are as SHOWN ON THE DRAWINGS.

Construction

1.3. Clearing & Disposal. Protect construction stakes and construction control markers.

Remove or treat all trees, snags, downed timber, brush, and stumps within the clearing limits according to the following specifications:

(a) Merchantable Timber. Deck or remove timber meeting Utilization Standards as specified in Appendix B.

(b) Unmerchantable Timber and all Construction Slash. Treat by windrowing unless scattering is specified by the Forest Servie.

(1) Method A. Windrow construction slash by placing it approximately parallel to and along the toe of the fill slope.

(2) Method B. Scatter or sidecast construction slash to within 24 inches of the ground outside the roadway without damaging trees. Limb all logs. Remove stumps from logs and place logs and stumps away from trees, positioned so they will remain in place and are not on top of one another.

Immediately remove slash deposited in stream courses.

Fell all dead trees outside the clearing limits that lean toward the road and are sufficiently tall to reach the roadbed. Fell hazard or unstable live trees that are sufficiently tall to reach the roadbed outside the clearing limits before felling trees within the clearing limits. Leave felled trees outside the clearing limits in place, and treat them no further if so directed by the Forest Service.

1.4. Pioneering. Do not undercut the final back slope during pioneering operations. Deposit material inside the roadway limits. Do not restrict drainage.

1.5. Grubbing. Grub stumps within the clearing limits as SHOWN ON THE DRAWINGS.

Stumps within the road embankment may remain if their tops are at least 4 inches below the finished traveled way surface elevation.

1.6. Excavation & Embankment. Construct the roadway to conform to the typical sections SHOWN ON THE DRAWINGS. Protect backslopes from being undercut. Embankment may be placed by side casting or push with a crawler tractor.

Install turnouts at points of opportunity with 1000 foot maximum spacing, 10 foot width, 50 foot length, and 25 foot tapers. Install turnarounds where needed for haul operations.
