T-838 MAINTENANCE FOR HIGH CLEARANCE VEHICLE USE (2/02)

838.01 Description

This work consists of making limited use roads passable for project use by Contractor and providing drainage from the traveled way and roadbed.

838.02 Maintenance Requirements

A. Traveled Way

Contractor may smooth or fill existing cross ditches and waterbars and by agreement modify existing road junction to enable vehicle access. Prior to beginning haul and resumption of haul after an extended stoppage:

1.

Remove brush, fallen trees, rocks, and other debris from traveled way, including turnouts, turnarounds, and other locations that interfere with needed maintenance as follows:

a.

No object extending over 100 mm (4 inches) above the road surface shall remain within the 3.6 m (12 feet) usable traveled way. Center the usable width on the roadbed or position away from the fill slope.

b.

Cut and remove standing or down trees, logs, brush, and limbs from within the area described in 1(a). Remove encroaching limbs to a height of 4.2 m (14 feet) above the traveled way surface. Scatter material not meeting utilization standards outside and below the roadbed on the fill side. Limb and remove timber which, meets utilization standards or deck at agreed locations.

c.

Place all removed materials away from drainages.

d.

During use, maintain drainage structures including dips, ditches and culverts in a usable condition.

2.

Clean and recondition drainage facilities in accordance with Section T-831 and T-834.

B. Slough and Slides

Slough and slides may be left in place, provided surface drainage is provided and at least 3.6 m (12 feet) of width is available for vehicle passage.

Contractor may reposition or ramp over slides and slough when the traveled way is less than 3.6 m (12 feet) providing the material is capable of supporting vehicles. Limit outslope to no more than six percent.

3.

Reposition slough or slide materials, which are not capable of supporting a vehicle, on the roadbed to provide the 3.6 m (12 feet) width. When directed by Forest Service, slough or slide material will be removed under Section T-832.

C. Slumps and Washouts

Drain the roadbed immediately upgrade of slumps and longitudinal cracks to prevent water from entering slump area.

Slumps and longitudinal cracks at the edge of the roadbed shall not be considered a part of the usable width. Usable width may be reduced to 3 m (10 feet) in the area of the slump.

Unless Forest Service agrees to material being placed on slumps, ramp the slumps on both ends into undisturbed roadbed to provide at least 3 m (10 feet) usable width. Use removed materials to guide vehicles to the ramp location or to aid in draining the area.

4.

Washouts may be filled with suitable material.

D.

Posthaul

At the end of hauling or prior to entering into seasonal shutdowns or a period of extended inactivity:

Shape the traveled way and disturbed roadbed to provide functional drainage.

Reinstall removed cross ditches and waterbars and provide any additional drainage structures necessary to offset changes caused through use and maintenance.

3. Leave roads useable for high clearance vehicles. Remove or reshape Contractor modifications at road junctions to leave the entrance as it was before use, or as agreed at the time of improvement.

T-839 MAINTENANCE FOR PROJECT USE (05/07)

839.01 Description

Work consists of providing minimum access required for Contractor's Operations and associated Forest Service contract administration and preventing unacceptable resource or road damage.

839.02 Maintenance Requirements

A.

Contractor is authorized to perform the following maintenance to provide vehicle passage and drainage:

Removing log, earth, and rock barriers and/or improving existing road junctions to enable vehicle access as mutually agreed.

Smoothing or filling existing cross ditches and water bars.

Installing Contractor-furnished culverts or other temporary drainage structures for shallow stream crossings as approved by the Contracting Officer.

Removing brush, fallen trees, rocks, and other materials from the traveled way and other locations that interfere with needed maintenance:

a.

Place all removed materials away from drainages.

b.

Limb and remove timber which meets utilization standards or deck at locations approved by the Contracting Officer. Scatter other woody materials, including limbs, off of and below the roadbed without creating concentrations.

5.

Clean and recondition drainage structures in accordance with Section T-831 and Section T-834.

6.

Reposition or ramp over slough and slides to provide adequate width of traveled way material.

7.

Provide traveled way drainage above slumps and seal cracks in slump area. Ramp the slumps on both ends into undisturbed roadbed to provide usable width unless otherwise ordered by the Contracting Officer.

B.

During use, the traveled way shall not channel water along the road. Prior to seasonal periods of anticipated rains and runoff, perform the following work:

Shape the traveled way and roadbed to drain.

Reinstall removed cross ditches and water bars and provide any additional drainage structures necessary to offset changes through use and maintenance.

Perform work outlined in 839.02 A (5), (6), and (7).

During periods of non use, replace original barrier or provide and maintain standard MUTCD, Type 3, barricades unless alternate type barriers are approved by the Contracting Officer.

839.03 Post Haul Requirements

A.

Upon completion of project use perform such work as needed to reasonably conform to the character of the existing road prior to Contractor's maintenance for project use, unless otherwise provided in the SUPPLEMENTAL SPECIFICATIONS or the Road Listing. Work shall be in addition to requirements of 839.02 B and in accordance with 839.03 B and C.

B.

Roads designated in the Road Listing to be blocked shall conform to the requirements of Section T-835. Unless otherwise approved by the Contracting Officer, remove Contractor-installed temporary structures from National Forest System land. Associated commercially-obtained materials shall remain the property of the Contractor.

C.

Remove or reshape Contractor improvements at road junctions, as approved by the Contracting Officer at the time of improvement.
