2. CONTRACTOR WORK REQUIREMENTS

2.1 Work Objective. Successful, quality performance will result in a roadbed with a clear line of sight free of vegetation and efficient function of roadbed ditches and drainage structures.

2.2 Roadbed Clearing and Grubbing. This work consists of clearing and grubbing vegetation, standing trees, and the removal of logs and windfall within the roadbed, shoulders, turnouts, intersections, ditches, drainage dips, catch basins, surface water deflectors and minor drainage structures.

Remove vegetation and obstructions from the work area which interfere with sight distance, road surface maintenance, drainage feature maintenance, and drainage features.

Roadbed clearing vegetation stumps not exceed two (2) inches in height and 1 (1) inch in diameter, and shall be cut as not to create a hazard to foot or vehicle traffic or impede roadbed surface maintenance.

Vegetation greater than 3’ in length and 2” diameter shall be scattered outside of the work area and water courses.

Slash and debris shall be scattered downslope from the roadbed and outside of the clearing limits, avoiding any concentration.

Remove organic, deleterious, and material larger than 6 inches brought to the surface during clearing and grubbing. Repair soft and unstable areas. Shape to a uniform surface and compact with approved equipment.

2.3 Roadside Clearing. This work consists of cutting or clearing vegetative growth including trees six (6) inches or less in diameter (when measured 6 inches above the ground) which interfere with the sight distance and drainage features outside of the roadbed but within the clearing limits. All brush and trees with a stump diameter of six (6) inches or less located inside the clearing limits, (with exception of the roadbed) shall be cut off no higher than six (6) inches above the ground level, as measured on the uphill side. Trim branches of trees designated to remain to a height of 14 feet over the road. Work also includes the removal of all logs and windfall within the specified clearing limits. The clearing limits are shown in the attached typical section. This includes a horizontal distance of ten (10) feet, (or a slope distance of 12 feet) from the bottom of the ditch for the roads with ditches, eight (8) feet horizontal distance (or a slope distance of 12 feet) from hinge without ditch, and a horizontal distance of four (4) feet (or a slope distance of six (6) feet) from the shoulder of the fill side. Clearing shall include turnouts and curves.

Slash and debris shall be scattered downslope from the roadbed and outside of the clearing limits, avoiding any concentration.

2.4 Drainage Facilities - Cleaning and Repair

Wood, rocks, and other debris shall be removed from roadside drainage ditches to provide unobstructed flow of water and disposed of on the jobsite as directed by the Contracting Officer's Representative. The back slope of the ditch shall not be undercut by ditch cleaning operations; and the slope to road shoulder shall be maintained at an approximate ratio of 3:1 from the bottom of the ditch to the edge of the roadbed.

Roadside ditches shall not be excavated to a depth of greater than 2 feet below roadbed grade. Typical depth of roadside drainage ditches below roadbed is one foot. Existing ditch dikes shall be restored, reshaped, and compacted as needed for effective drainage through culverts. Remove projecting roots, stumps, rock, or similar obstructions which have the potential to block water from entering the structure or divert water outside the defined channel.

Slash and debris shall be scattered downslope from the roadbed and outside of the clearing limits, avoiding any concentration.

Repair soft and unstable areas. Shape to a uniform surface and compact with approved equipment.

2.5 Equipment.

Contractor shall make equipment available for inspection and approval before use. Equipment provided to conduct work must meet or exceed the following minimum specifications unless otherwise approved the Contracting Officer:

2.5.1 Hydraulic Excavator. 90 - 220 SAE net horsepower track mounted hydraulic excavator, year 2005 or newer. Bucket must be equipped with a hydraulic "thumb". It is anticipated that an excavator of a size capable of performing the excavation needs for the project, including but not limited to structure excavation, will be of an adequate size to be acceptable for any work that the Contractor may be directed to perform under this section.

2.5.2 Tractor Mower. 75 SAE net horsepower rubber tired tractor with side mount rotary head boom mower, year 2005 or newer, capable of cutting up to 6” inch diameter vegetation.

2.5.3 Moving of Equipment and Supplies. The moving of equipment and supplies to the job site and between job sites shall be the contractor's responsibility and is incidental to Pay Items as shown in the Schedule of Items and no separate payment shall be made.

2.5.4 Replacement of Equipment. Contractor shall provide quality equipment capable of safely performing the work under the terms of the contract. All repairs are the total responsibility of the Contractor.

2.6 Pollution and Erosion Control. During all operations under this contract, the Contractor shall exercise reasonable measures to direct surface runoff water to stabilized waterways and to keep the drainage systems functioning effectively to prevent or minimize soil erosion and pollution of water and other resources. All refuse, including garbage, rubbish, and solid or liquid wastes from the Contractor's operations, including camps, parking areas, and equipment maintenance areas shall be stored and collected in a sanitary manner and disposed of in a State-approved sanitary landfill.

Oil from crankcases or gear boxes, equipment waste or spilled or excess fuel shall be placed in containers and removed from the work site and disposed of as approved and required by Federal, State and Local laws.

Equipment uses for operations in close proximity to streams or bodies of water will be required to meet more stringent requirements regarding seals and fittings that prevent the leaking of hydraulic fluids, lubricants and fuels. Failure to comply will result in immediate rejection of equipment.

3. ACCEPTANCE REQUIREMENTS

3.1 Contractor Quality Control Inspection.

The Contractor, is responsible for management and quality control actions to meet the terms of this contract.
