E. Surface Maintenance and Drainage Maintenance – Combined Activities

Task orders which include activities that combine surface maintenance, ditch cleaning, and culvert cleaning shall reference this section (811) for surface maintenance and shall reference section 834 for ditch cleaning and culvert cleaning requirements.

811 – SURFACE MAINTENANCE 16

F. Roadway Reconditioning shall be inclusive of the following

Ditch Reconditioning. Remove slide material, sediment, vegetation, and other debris from existing ditches and culvert inlets/outlets. Reshape ditches and culvert inlets/outlets to achieve positive drainage and uniform ditch width, depth, and grade. Dispose of waste at designated sites or as directed by the CO.

Shoulder Reconditioning. Remove slide material, vegetation, and other debris from existing shoulders including shoulders in parking areas, turnouts, and other widened areas. Repair soft and unstable areas. Reshape shoulders to the widths and slopes of surrounding terrain.

Dispose of waste at designated sites or as directed by the CO.

Roadbed Reconditioning. Remove organic, deleterious, and material larger than 6 inches from the top 6 inches of subgrade. Dispose of waste as directed by the CO. Repair soft and unstable areas. Scarify surface to a 6-inch depth. Remove irregularities and shape to a uniform surface. Finish earth surfaces to within 0.05 feet and rock surfaces to within 0.10 feet of required line, grade, and cross-section. Compact using vibratory equipment suitable for the activity until visual displacement ceases.

Aggregate Surface Reconditioning. Repair soft and unstable areas to the full aggregate surface depth. Scarify the thickness of aggregate surfacing material or to 6 inches, whichever is less. Remove irregularities and shape to a uniform surface. Finish and compact the surface to maintain existing grades and using compaction equipment suitable for the activity until visual displacement ceases.

G. Surface Treatment Application (Electrolyte Emulsion)

1. Equipment: Equipment required for electrolyte emulsion application includes: tanker or water truck with spray bar, grading equipment (i.e., bulldozer or motorgrader), and roller.

Equipment is widely available in most areas, but availability may be limited in remote areas.

2. Manufacturing/Mixing Process: Electrolyte concentrate must be mixed with water to achieve the desired concentration level prior to application. Dilution ratios of 1 part electrolyte concentrate mixed with 100 to 600 parts water or more are common.

3. Placement Process: Electrolyte emulsions can be applied by a sprayed-on method or mixed in method, but mixed-in method is most common. Recommended mixing depth for dust suppression and stabilization ranges from 25 to 50 mm (1 to 2 in) and 100 to 200 mm (4 to 8 in), respectively. The moisture content of the soil prior to treatment should be below optimum for compaction so that the soil moisture content will be near optimum once the electrolyte emulsion is added, considering the water provided by the emulsion; if the material is very dry or saturated, processing to achieve moisture content adjustments is recommended prior to treatment. For dust suppression applications, scarifying the surface allows the electrolyte emulsion to penetrate evenly and quickly into the road surface. For soil stabilization applications, the soil is loosened to the desired treatment depth. The electrolyte emulsion is then applied uniformly using a tanker or water truck with a spray bar and mixed with the loose soil. The electrolyte emulsion is often applied in multiple passes to get better overall mixing. Once mixed, the treated material is graded and compacted.

811 – SURFACE MAINTENANCE 17

4. Weather Restrictions: Do not apply electrolyte emulsions if is raining or if temperatures are below freezing.

5. Application Rate: Electrolyte emulsion application rates are in the range of 2,000 to 5,000 m2/day (2,400 to 6,000 yd2/day).

6. Lane Closure Requirements: The roadway lane should be closed during application, but can be opened to traffic once application and mixing activities are complete.

Location of Work

As specified on roads listed on the road listing, shown on the plans, marked on the ground, or as ordered by the Contracting Officer. Locations of weed infested areas are marked on the ground. Do not operate in the weed infested areas unless ordered to do so by the Contracting Officer.

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. Road Mile: Work activity will be measured along the centerline of the road regardless of the number of lanes.

Payment

The accepted quantities will be paid at the contract price per unit of measurement for the Section 811 pay items listed in the schedule of items. Payment will be full compensation for the work prescribed in this Section.

833 - DRAINAGE STRUCTURE INSTALLATION OR REMOVAL (08/21/07) 24

833 DRAINAGE STRUCTURE INSTALLATION OR REMOVAL

This section shall be construction under the DBA wage determination.

Install or remove drainage structures including culverts, water-bars, drivable drain dips, and cross ditches.

Culvert Removal – This activity consists of removing damaged or undersized culverts from the roadbed. The COR will indicate which culverts will be removed. Remove structures and obstructions in the roadbed to 12 inches below subgrade elevation. Remove structures and obstructions outside the roadbed to 12 inches below finished grade or to the natural stream bottom. The material removed shall become the property of the Contractor and removed from National Forest System Lands. The placement of new culvert will be paid for under Culvert Installation.

Remove Culvert, Install Rolling Dip Culvert Removal with Installation of Rolling Dip – This activity consists of removing damaged or undersized culverts from the roadbed and constructing a Rolling Dip to replace the culvert. The COR will indicate which culverts will be removed. The material removed shall become the property of the Contractor and removed from National Forest System Lands. The rolling dip shall be constructed to the dimensions shown on Drawings.

Construct New Rolling Dip - This activity consists of the contractor constructing a rolling dip at locations directed by the FS. Dips shall be constructed to dimensions shown on Drawings.

Furnish and Install Culvert –This activity consists of furnishing and installing 18” - 36” Aluminized Type II Coated Corrugated Metal Pipe, inclusive of bands needed for joining multiple pipe sections, and including all bedding and backfilling materials required to complete the work. The maximum depth of culvert installation shall be 5 ft from the finished road surface to the pipe inlet. Activities required for dewatering the jobsite shall be incidental to the culvert installation. The COR will specify the size, length, and location of pipe.

Lay the bottom of the pipe so that it is in contact with the bedding throughout its length.

Place outside laps facing upstream. Ensure that the final installed alignment allows no reverse grades. The COR shall inspect and approve the bedding and pipe alignment prior to backfill.

After bedding is prepared and the pipe is placed, compact the backfill using a mechanical hand tamper (or other suitable vibratory equipment designed for this purpose) under the haunches and alongside the pipe. Use backfilling material that is free of frozen or solid clumps larger than 3 in diameter. On each side of the pipe, place an area of compacted material at least as wide as the diameter of the pipe. Compact the backfill without damaging or displacing the pipe. Place a minimum of 12 inches of compacted material on top of the pipe.

833 - DRAINAGE STRUCTURE INSTALLATION OR REMOVAL (08/21/07) 25

Standard

Drainage structure installation is complete when culverts, water-bars, drivable drain dips and cross ditches have been installed to the lines and grades specified. Drainage structure removal is complete when designated culverts, water-bars and cross ditches have been removed and culverts have been properly disposed of off of National Forest property.

Location of Work

As specified on roads listed on the ROAD LISTING, SHOWN ON THE PLANS, or as ordered by the Contracting Officer.

Payment

Payment will be full compensation for the work prescribed in this Section.

834 - DRAINAGE STRUCTURE MAINTENANCE (03/21/2007) 26

834 ROADWAY DRAINAGE SYSTEM MAINTENANCE

Service Required

Clean and recondition roadway drainage systems including culverts, ditches, inlet and outlet channels, catch basins, and appurtenances.

Restore Road Ditches - All ditches shall be maintained in their original location to the shape and grade required to insure drainage of the roadway. Drainage structures and road appurtenances shall not be damaged during this operation. Handwork required to properly connect ditch flow lines to drainage structure inlets is considered a part of this activity.

Road Ditches. All suitable material (having the same character as the road surface) excavated through this activity shall be reclaimed and used within the traveled way.

Unsuitable material shall be spread along road shoulders or fill slopes to assure road surface drainage and preventing unsuitable material being pulled onto aggregate surfaces.

Tail and Lead-Off Ditches. Ditches shall be opened to provide drainage away from the roadway, with no berms left at the end of these ditches to block water (daylight).

No material excavated from these structures shall be reclaimed onto the roadbed.

Culvert Cleaning All culverts shall be inspected and cleaned as necessary of dirt, silt, muck, debris and vegetative matter to maintain a smooth flow of water. Silt shall be removed from culverts so that no more than 2” of debris is left in any pipe, except that all silt shall be removed from the first 3’ at both outlet ends of culverts. This activity also includes – brushing and debris removal at culvert inlets and outlets, catch basins, and other appurtenant structures such that they drain to daylight. All culverts shall be brushed out around the edge of the pipe and minimum of 10’ in all direction of grass, brush and trees with a DBH of 4” or less.

Throughout this operation, care shall be taken to prevent damage to culvert pipes, end sections and all other appurtenances. All material, including brush, extracted in this operation shall be disposed of at the site outside of the roadway from natural or man-made drainages.

Performance Standard

Drainage system maintenance is complete when no obstruction remains in the defined area adjacent to the structure or in ditches which would have the potential to block water from entering the structure, back water into the structure (except for structures designed to function in a back-flooded manner), or divert water outside the defined channel. This includes clearing obstructions from culvert inlets and outlets when
