PART 12 - PRODUCTS (Not Applicable)

PART 13 - EXECUTION

13.1 CLEARING AND GRUBBING

A. All trees, brush, shrubs, stumps, roots, and other vegetative material and debris within the designated clearing limits, shall be cleared, grubbed, removed, and disposed of except the following condition:

1. Those items designated to remain by the Contract or Contracting Officer.

2. Undisturbed stumps outside the roadway, trailway, and parking area, provided they do not extend more than 12 inches above the original ground (measured from the uphill side) and are not closer than 2 feet from the edge of road or parking area, are not in the cut or fill slopes, and they do not interfere with the placement or compaction of embankments.

B. All roots over 3 inches in diameter within the roadbed area shall be grubbed to a minimum depth of 6 inches below subgrade. Roots over 3 inches in diameter protruding from the excavated slope shall be cut flush with the excavated slope surface.

C. Clearing slash shall be treated in accordance with “Slash Treatment” paragraph below.

D. Trees shall be felled within the clearing limits, usually towards the center, so as to prevent damage to the trees that are to be left standing. In some cases, controlled felling, cutting of trees into sections from the top downward, or other means shall be used when required to prevent damage to property, structures, traffic, and trees/vegetation to remain.

E. Branches on remaining trees or shrubs shall be trimmed to give a clear height of 14 feet above the roadbed unless otherwise shown on the Drawings. Tree limbs shall be trimmed as near flush with the trunk as practicable.

13.2 UTILIZATION OF TIMBER

A. Merchantable timber is timber that meets Utilization Standards. Utilization Standards shall be trees larger than 8-inches in diameter measured 12-inches above grade.

B. Utilization and Removal of Timber: Trees that meet “Merchantable Timber” standards shall be treated as follows:

1. Logs meeting utilization standards shall be limbed and decked at locations shown on the Drawings or approved by the Contracting Officer. Decking shall be done in such a manner that logs are piled parallel one to the other, can reasonably be removed by standard log loading equipment, will not damage standing trees, and will not roll. Decks shall be free of brush and soil. Title to all such timber cut from National Forest land shall remain with the Forest Service, U.S. Department of Agriculture, in accordance with its regular procedures, unless otherwise specified.

2. Removal from Government Land. Merchantable timber, designated for removal, shall become the property of the contractor without charge and removed from Government land. This timber shall not be exported from the United States nor used as substitution (as defined in 36 CFR 223 Subpart D) for timber from private lands exported by the contractor or an affiliate directly or indirectly.

3. Logs meeting utilization standards shall be limbed, cut into 16-inch to 36-inch lengths, and stacked in various locations throughout the recreation development.

Logs stacked shall be stable and free of brush and soil.

4. Disposal as Unmerchantable Timber. Timber on this project is not considered merchantable and shall be disposed of in accordance with “Slash Treatment” paragraph below.

13.3 PIONEER

A. Pioneering operations shall be done in a manner that prevents undercutting of final excavation slopes, maintains materials within the road, trail, or parking limits, and controls runoff.

13.4 SLASH TREATMENT

A. Treatment of construction slash larger than 3-inches in diameter and 3-feet in length shall be accomplished by one or more of the following methods as Designated by the Contracting Officer:

1. Scattering: Construction slash shall be scattered outside the clearing limits without damaging trees. All logs shall be limbed and placed away from trees, positioned so they will not roll, and not be placed on top of one another. Stumps shall be removed and disposed of off site. Other construction slash shall be limbed and scattered to reduce slash concentrations.

2. Burying: Construction slash shall be buried at the locations shown on the Drawings and designated on the ground. Construction slash shall be matted down in layers and covered with at least 2 feet of rock and soil. The final surface shall be smoothed and sloped to drain.

3. Chipping: Construction slash up to at least 3 inches in diameter and longer than 3 feet shall be processed through a chipping machine. Chips shall be deposited on embankment slopes or outside the roadway to a loose depth not exceeding 6 inches.

Minor amounts of chips may be permitted within the roadway if they are thoroughly mixed with soil and do not form a layer.

4. Piling and Burning: Construction slash shall be deposited in areas shown on the Drawings and designated on the ground. Piles shall be constructed so that burning does not damage standing trees. If burning is incomplete, the slash remaining shall be repiled and burned until pieces are reduced to less than 3 inches in diameter and 3 feet in length. These pieces shall then be scattered.

5. Decking Unmerchantable Material: Logs not meeting utilization standards and other material that exceeds 8-inches in diameter shall be decked in areas shown on the Drawings and approved by the Contracting Officer. Material shall be cut into lengths not to exceed 32 feet and all limbs removed. Decks shall be stable and free of brush and soil.

6. Stacking of Unmerchantable Material: Logs not meeting utilization standards and other material that exceeds 4-inches in diameter shall be limbed, cut into 16-inch to 36-inch lengths, and stacked in various locations throughout the recreation development. Log stacked shall be stable and free of brush and soil.

7. Removal: Construction slash shall be removed or hauled to locations shown on the Drawings and designated on the ground.

8. Piling: Construction slash shall be piled in areas shown on the Drawings and designated on the ground for later burning or disposal by others. Piles shall be placed and constructed so burning will not damage remaining trees. All stumps shall be reasonably free of dirt. Unmerchantable logs shall be cut into lengths less than 20 feet prior to placement in the pile.

9. Placing Slash on Embankment Slopes: Construction slash shall be placed on completed embankment slopes to reduce soil erosion where shown on the Drawings. Construction slash shall be placed as flat as practicable on the completed slope. Slash shall be placed from the toe of the embankment to a point at least 2 feet below subgrade elevation. Priority for the use of available slash shall be given to (1) through fills, (2) inside of curves, and (3) ditch relief outlets.

B. Construction slash less than 3 inches in diameter and 3 feet in length may be scattered within the clearing limits.

C. No construction slash shall be deposited in lakes, meadows, streams, or streambeds.

Construction slash that interferes with drainage structures shall be removed immediately.
