842 CUTTING ROADWAY VEGETATION

1. DESCRIPTION

This work consists of cutting all vegetative growth including trees and other vegetation less than four (4) inches in diameter.

2. MAINTENANCE REQUIREMENTS

a. General

1) Brush, trees, and other vegetation less than four (4) inches in diameter within each area treated shall be cut to a maximum height of six (6) inches above the ground surface or obstruction such as rocks or existing stumps. When work is performed under this Section, the Contractor shall remove all limbs which extend into the treated area or over the roadbed to a height shown in the drawings.

2) Signs, markers, and other road appurtenances are designated to be retained. Other items to remain will be marked on the ground.

3) The width of the vegetation to be cut shall be as shown in the Special Project Specifications.

4) Vegetative matter removed from the roadway shall be disposed by the following method(s).

• Scattering: Clearing slash shall be scattered to reduce slash concentrations with slash generally left within 18" of the ground. Slash shall be scattered into openings away from and without unnecessary damage to residual trees. All scattered logs shall be limbed, placed away from trees and positioned so they will not roll.

• Removal: Clearing slash shall be moved or hauled to a location designated by the Forest Service and piled for disposal by the Forest Service.

• Chipping and Scattering; Chippable slash up to 4 inches in diameter shall be processed through a chipping machine. Chips shall be scattered to a loose depth not to exceed 6 inches.

• Chipping and Removal; Chippable slash up to 4 inches in diameter shall be processed through a chipping machine. Chips shall be removed from National Forest lands.

• Bucking: Clearing slash larger than 4 inches in large end diameter shall be bucked into lengths not to exceed 6 feet. Bucked lengths shall be left in place and positioned so they will not roll.

• Piling: Clearing slash 4 inches and smaller in large end diameter shall be hand piled for Forest Service disposal. Piles shall be reasonably compact and free from soil, and shall have a 3-foot fireline cleared to mineral soil.

• Disposal sites shall be approved by the Forest Service.

5) Damage to trunks of standing trees caused by Contractor's operation shall be corrected by Contractor, either by treatment with a commercial nursery sealer or by removing the tree as directed by the Government.

6) Mechanical brush cutters shall not be operated when there are non-Contractor personnel or occupied vehicles within a hazardous distance of immediate operating area.

7) Trees within the cutting limits which are over four (4) inches in diameter shall be limbed in lieu of cutting

8) When trees are limbed, limbs shall be cut within four (4) inches of the trunk

b. Cutting Side Vegetation

1) Pass mile work will be ordered in four (4) foot increments of width regardless of slope deviations.

2) Side mile work will be ordered in uniform width for the length of the listed segments of roads.

3) Unless otherwise included in Special Project Specifications work shall commence at the edge of the traveled way and proceed away from the road centerline. For roads without a defined traveled way the starting point for cutting will be marked in the field or defined in Special Project Specifications.

c. Debris

1) Materials resulting from the cutting operation in excess of one (1) foot in length or three (3) inches in diameter, shall not be allowed to remain on roadway slopes within the treated area, in ditches, or within water courses.

2) Limbs and chunks in excess of three (3) inches in any dimension shall be removed from the traveled way and shoulders.

3) Materials may be scattered downslope from the roadbed, outside of the work area and drainages. Concentrations shall be rescattered or removed.

3. MEASUREMENT

a. Measurement for cutting vegetation by the pass mile will be determined by the number of four

(4) foot passes ordered and accepted. Partial increments ordered to complete the outside edge of backslope or fill slope cutting and transitions will be measured as full passes. The length of each pass will be determined to the nearest one-tenth (1/10) mile on each road.

b. Measurement for cutting side vegetation by the side mile will be the length of roads or segments ordered and accepted. The length will be determined to the nearest one-hundred (1/100) mile on each side of each road.

c. No reduction in the mileage between road terminal shown on the road listing will be made for areas where there is little or no vegetation to be cut.

4. PAYMENT

a. The accepted quantities will be paid at the unit price shown in the Schedule of Items.

b. Payment will be made under:
