800 – DEFINITIONS AND ABBREVIATIONS

1.1 Definitions

Wherever in these specifications, the following terms, or pronouns in place of them, are used, the intent and meaning shall be interpreted as follows:

Catch Basin. The area immediately adjacent to inlet invert of the culvert.

Channel. A natural waterway leading into or away from a culvert or bridge.

Cross ditch. A shallow ditch placed across the roadbed to remove water from the roadbed surface that can be driven across by full-size pickups or other high clearance vehicles; usually placed diagonal to the centerline.

Culvert. Any structure with a bottom, regardless of fill depth, depth of invert burial, or presence of horizontal driving surface, or any bottomless (natural channel) structure with footings that will not have wheel loads in direct contact with the top of the structure.

Lead-off ditch. A ditch used to remove water from roadside drainage ditches, the roadway, cattleguards, or drainage structures such as culverts and drainage dips.

Drain Dip. Is an out sloped depression along a road alignment that is constructed both to disperse runoff from the road surface and to allow passage of motor vehicles at reduced road speeds. Drain Dips shape the road surface to have a gentle reverse grade that directs water off the road rather than allowing water to run down the road.

Drainage structure. A term identifying manufactured devices placed to control water movements. A structure installed to control, divert, or move water off or across the road, including but not limited to culverts, bridges, draining dips, rolling dips, and water bars.

Excess Material. Material from the roadway in excess to that needed for maintenance of roadway.

Grade. The vertical alignment of the top surface of the road.

High Clearance Vehicles. A high clearance vehicle is defined as a SUV or truck type vehicle, with at least 6 inches of clearance or more from the lowest point of the frame, body, suspension, or differential to the ground.

Passenger Vehicles. Standard passenger cars with no more than 6 inches of clearance and may be legally operated on public highways.

Paved Surface or Pavement. Denotes asphalt, concrete, or other stabilized materials excluding natural aggregates. Dust palliative treatments are not considered as pavement.

Roadbed. The portion of a road between the intersection of the subgrade and side slopes, excluding that portion of the ditch below the subgrade.

Slough or Slide. Material deposited on the roadway that may need to be repositioned or removed.

Slump. A localized portion of the roadbed that has slipped, or otherwise become lower than the adjacent roadbed, and constitutes a hazard to traffic.

Turnouts. A short auxiliary lane on a one-lane road provided for passage of meeting vehicles.

Unsuitable Material. Material removed during maintenance, which must be disposed of in designated locations. Includes material with substantial amounts of vegetation or other objectionable material.

Waterbar - Are abrupt changes in the shape of the road intended to reduce erosion and control traffic. Waterbars are similar to Drain Dips, but are shorter and more frequent.

Work Listing. Each task order will include a listing of the road number, road name, and description of work to be performed by mile post.

Work Schedule. The Service Provider's current schedule for work planning and progression to complete work within the period of performance.

1.2 Quantity Measurement Terms

U.S. Customary Units of measure are used in conjunction with these specifications.

The methods of measurement and computation will be those necessary to accurately determine the quantities of materials furnished and work performed.

833 – DRAINAGE STRUCTURE RECONDITION

833.01 Service Required:

Remove or replace drainage structures including ditch relief culverts, drivable water-bars, drain dips, and cross ditches. Corrugated Metal Pipes (CMP) and Heavy Duty Plastic Pipes (HDPE) removed shall be disposed off NFS lands in accordance with local, state, and federal regulations. This includes all excavation and backfill.

833.02 Performance Standard:

A. Drainage structure installation or replacement is complete when designated water-bars, ditch relief culverts (DRC), or cross ditches have been installed to the lines and grades specified. A DRC is an 18” or 24” conduit installed beneath the road surface to relieve drainage in longitudinal ditches at the toe of the back slopes.

B. Standards when installing ditch relief culverts:

1. Ditch relief culverts should be located and installed sufficiently upgrade of watercourse crossings so that water and sediment can be filtered through a vegetated slope before reaching the stream.

2. Ditch relief culverts shall be staked by the Forest Service prior to installation.

3. Ditch relief culverts should be installed at intervals along the road that are close enough to prevent significant erosion of the ditch and below the culvert outfall on the native hillslope.

4. Ditch relief culverts should be installed at locations where collected water and sediment is not discharged directly onto unstable areas or into watercourses.

5. Replace any pipe that is distorted by more than 5 percent of nominal dimensions, or that is ruptured or broken.

6. On each side of the pipe, excavate an area at least as wide as the diameter of the pipe. Backfill without damaging or displacing the pipe. Complete backfilling of the trench with suitable material

7. Standard excavation depth is typically no more than 5’ depth at road centerline and a standard backhoe will suffice for installation.

C. Drainage dips shall be shaped to a depth and width to provide drainage and in reasonable conformity to the original lines, grades, and cross sections unless others identified in the task order or designated on the ground. Handwork may be necessary to obtain a smooth surface and uniform cross section. Lead off ditches shall be cleaned for a distance of (10) feet from the drainage dip.

D. Culvert cleaning for pay items 833(11), 833(12), and 833(13) include removing any material with inlet and outlet of pipe. Culverts which have silted in to a depth of ¼ of their opening height or more shall have their inlet and outlets cleaned as well as (3) feet of the upper and lower ends of the inside cleaned out to expose the full diameter of the culvert.

E. Culverts shall have their inlet and outlet cleaned as well as three (3) feet of the upper and lower ends of the inside cleaned out to expose the full diameter of the culvert. If debris is lodged in the culvert to the extent it cannot be cleaned by shovel, bar, and hand labor, the COR shall be notified of the location within 5 working days for a final determination of corrective measures to be taken.

F. Compact backfill:

1. Adjust the moisture content of the backfill material to a moisture content suitable for compaction. Compact each layer 6 inch layer loose material depth with a minimum of three complete passes or until visual displacement ceases using a mechanical tamper.

833.03 Location of Work:

As SPECIFIED IN THE TASK ORDER or as ordered by the Contracting Officer.

833.04 Measurement:

Measurement under this Section will be made by the total number of units for each item listed in the SCHEDULE OF ITEMS completed and accepted.

A. Linear Foot (LF): Measure the work along its length from end to end; parallel to the base or foundation; along the top; along the front face; or along the invert. Do not measure overlaps. Measure to the nearest linear foot.

A. Each: One entire unit. Measure the actual number of units completed and accepted.

B. Cubic Yard: The quantity will be the number of cubic yards measured in the vehicles.

833.05 PAYMENT:

A. The accepted quantities will be paid at the contract price per unit of measurement for the Section 833 pay item listed in the schedule of items. Payment will be full compensation for the work prescribed in this Section.
