106 - Acceptance of Work 106.01_National_7_18_2017

Delete Subsection 106.01 and replace with the following:

106.01 Conformity with Contract Requirements.

Follow the requirements of FAR Clause 52.246-12 Inspection of Construction.

References to standard test methods of AASHTO, ASTM, GSA, and other recognized standard authorities refer to the methods in effect on the date of solicitation for bids.

Perform all work to the lines, grades, cross-sections, dimensions, and processes or material requirements shown on the plans or specified in the contract.

Incorporate manufactured materials into the work according to the manufacturer’s recommendations or to these specifications, whichever is more strict.

Plan dimensions and contract specification values are the values to be strived for and complied with as the design values from which any deviations are allowed. Perform work and provide material that is uniform in character and reasonably close to the prescribed value or within the specified tolerance range. The purpose of a tolerance range is to accommodate occasional minor variations from the median zone that are unavoidable for practical reasons.

When standard manufactured items are specified (such as fence, wire, plates, rolled shapes, pipe conduits, etc., that are identified by gauge, unit mass, section dimensions, etc.), the identification will be considered to be nominal masses or dimensions. Unless specific contract tolerances are noted, established manufacturing tolerances will be accepted.

The Government may inspect, sample, or test all work at any time before final acceptance of the project.

When the Government tests work, copies of test reports are furnished to the Contractor upon request.

Government tests may or may not be performed at the work site. If Contractor testing and inspection is verified by the Government, the Contractor’s results may be used by the Government to evaluate work for acceptance. Do not rely on the availability of Government test results for process control.

Acceptable work conforming to the contract will be paid for at the contract unit bid price. Four methods of determining conformity and accepting work are described in Subsections 106.02 to 106.05 inclusive.

The primary method of acceptance is specified in each Section of work. However, work may be rejected at any time it is found by any of the methods not to comply with the contract.

Remove, repair, or replace work that does not conform to the contract, or to prevailing industry standards where no specific contract requirements are noted. Removing, repairing, or replacing work;

providing temporary traffic control; and any other related work to accomplish conformity will be at no cost to the Government.

(a) Disputing Government test results. If the accuracy of Government test results is disputed, promptly inform the CO. If the dispute is unresolved after reasonable steps are taken to resolve the dispute, further evaluation may be obtained by written request. Include a narrative describing the dispute and a proposed resolution protocol that addresses the following:

1. Sampling method;

2. Number of samples;

3. Sample transport;

4. Test procedures;

5. Testing laboratories;

6. Reporting;

7. Estimated time and costs; and

8. Validation process.

If the evaluation requires additional sampling or testing be performed, mutually agree with the Government on witnessing procedures and on sampling and testing by a third party laboratory. Use a third party laboratory accredited by the AASHTO accreditation program. Provide proof of the laboratory’s accreditation for the test procedures to be used. Do not use the same laboratory that produced the disputed Government test results or that produced the test results used as a basis for the dispute.

The CO will review the proposed resolution protocol and may modify it before final approval and execution.

The Government will use the approved resolution protocol test results to determine the validity of the disputed testing. If the Government test results are validated, the Contractor will be responsible for all costs associated with developing and performing the resolution protocol. If the Government test results are not validated, the Government will be responsible for all costs associated with developing and performing the resolution protocol. If the validity of the Government test results cannot be determined, the Contractor and Government will equally share all costs associated with developing and carrying out the resolution protocol.

(b) Alternatives to removing and replacing non-conforming work. As an alternative to removal and replacement, the Contractor may submit a written request to:

1. Have the work accepted at a reduced price; or

2. Be given permission to perform corrective measures to bring the work into conformity.

The request must contain supporting rationale and documentation. Include references or data justifying the proposal based on an evaluation of test results, effect on service life, value of material or work, quality, aesthetics, and other tangible engineering basis. The CO will determine disposition of the nonconforming work.

Delete Section 211 in its entirety and replace with the following.

Description.

211.01 This work consists of obliterating or decommissioning roads, including decompaction to 16 inches or to the depth of compaction, recontouring to the natural slope profile, mulching and planting with native material, and other incidental work. This includes furnishing all labor, equipment, supervision, transportation, supplies, and incidentals.

This work also consists of the removal of culverts and restoration of stream channels, including pumping or diverting of live streams, in channel rock placement, and other miscellaneous items required for execution of the work.

Roadway obliteration methods are designated as follows:

(a) Method 1. Obliterate the roadway by restoring to approximate original ground contours. Keep excavated material within the original construction limits. Finish slopes to provide gradual transitions in slope adjustments without noticeable breaks.

The finished surface shall remain rough not allowing water to flow directly down the fall line of the finished slope.

211.02 Definitions

(a) Coarse woody debris – woody material greater than 3-inch diameter on the small end and longer than 6 feet in length, including live trees removed from the roadway.

(b) Native mulch – includes topsoil, organic material, and coarse woody debris broken into smaller pieces that exist in the vicinity of the road.

(c) Soil and vegetative transplants – vegetation, which includes the plant or organic matter on the surface of the ground and the root system, transplanted from the roadway or adjacent area onto prepared (decompacted and recontoured) roadway. Transplanted material contains sufficient root mass and surrounding soil to maintain and incorporate nutrients, soil microbes and other organisms. Vegetative material includes native shrubs, sod, and bunch grass.

Obliteration Requirements

211.03 Conform to the following when obliterating roadways:

(a) Vegetation removal. Remove vegetation including dead woody debris, trees, stumps, roots and other vegetation within the limits of the immediate obliteration area prior to starting excavation operations and pile temporarily until recontouring has been completed. Preserve suitable vegetation in road prism to be transplanted after compacted soil has been loosened. Place clearing slash back on top of recontoured road segments and completed channel side slopes in stable positions that do not interfere with stream channel flow according to Subsection 211.03(e).

(b) Decompaction of roadbed. Loosen compacted soil down to 16 inches over the entire width of the roadbed and ditches through the use of a trackhoe excavator bucket.

(c) Recontouring of roadway. Following decompaction of the roadway, pull the fill material up and place on the loosened roadbed between the top of cut and original ground, forming a slope approximating natural contours as shown on the plans, but also retaining a rough surface to slow the flow of water across the new fill slope. Fill in all ditches and other water traps, and remove all berms. Blend all finished slopes to match the surrounding terrain. Notify the inspector a minimum of 48 hours in advance of areas where full recontouring may not be achievable. If full recontouring is determined not to be practical or attainable by the CO, the CO may approve a partial recontour at a specific site.

(d) Transplanting of vegetative material. Transplant soil and vegetative material clumps from the road surface and adjacent areas into the recontoured road prism at a minimum rate of 30 plantings per 100 lineal feet of roadway measured along centerline. Excavate transplanting clumps of sufficient size to maintain root systems and adequate soil to enhance favorable growth. If the soil and vegetative clump breaks up and cannot be maintained, transplant the loose material right side up as best as possible.

(e) Treatment of the recontoured roadway surface. Cover the disturbed area with a combination of transplants, native mulch, coarse woody debris, or agricultural straw (certified weed-free). If the transplants, native mulch, and course woody debris cannot meet the minimum coverage requirements of 50% coverage then coverage will be augmented with agricultural straw to obtain a minimum of 50% to a maximum of 80% ground coverage. The priority of coverage is as follows; soil and vegetative transplants, native mulch, and coarse woody debris, then apply agricultural straw at a rate of 1 bale per 400 square feet only when necessary to achieve the required coverage. Avoid burying any cover material. The end goal of the treatment should be to match the adjacent landscape coverage as closely as possible.

Place the course woody debris in various size classes over the recontoured roadway in a perpendicular pattern to the newly constructed slope to impede and slow the flow of water across the new slope.

Do not leave vegetation removed under Subsection 211.03(a) "hung-up" in remaining live vegetation.

(f) Treatment of stream channel crossings. For intermittent and perennial stream channels remove all fills and recontour to the original ground slopes.

(1) Stream channel crossings with culverts. Notify the inspector a minimum of 48 hours in advance for stream channel work to ensure the inspector is present. For live stream crossings, install one or more sedimats at an approved location downstream of the culvert that span the entire width of the stream prior to starting work. Construct a stream diversion using pipe, a lined open channel, pumps, or other approved methods to dewater the crossing prior to culvert removal. Dispose of metal culverts by removal from National Forest land. Treat removed log culverts as coarse woody debris and use as directed in Subsection 211.03(e).

3.

4. Reconstruct the stream channel width, depth, and banks after the drainage structure has been removed to have approximately the same dimensions and general shape as those outside the crossing area. Remove all bedding materials and incorporate into the surrounding recontouring work. Construct a uniform grade from the natural stream channel above the inlet location to the natural channel below the outlet to create a free draining, unconstricted channel for the entire length unless otherwise noted on the plans. Incorporate excavated material into the adjacent recontouring areas. Conserve suitable rock encountered for construction of stream grade control structures and individual rock placement in the new channel as shown on the plans and as directed by the engineer.

5.

6. Re-water the newly constructed channel slowly. Remove all stream diversion materials prior to final site rehab and remove the sedimats from the impacted stream channel and lay them out flat on the adjacent recontoured roadbed.

7.

(2) Stream channel crossings without culverts. Notify the inspector a minimum of 48 hours in advance for stream channel work to ensure inspector is present. Prior to crossing open stream channels with live water where the culvert has been previously removed, install one or more sedimats at an approved location downstream of the crossing that span the entire width of the stream prior to starting work. Place logs suitable for support of crossing equipment in the channel parallel to the stream bank.

Provide sufficient spacing between the logs so that the stream flow is not constricted.

Remove all fill material down to original ground and incorporate into the surrounding recontouring work.

Remove the crossing logs following the final equipment crossing and utilize as coarse woody debris as directed in Subsection 211.03(e). Remove the sedimats from the stream channel and lay them out flat on the adjacent recontoured roadbed, Rehabilitate all disturbed stream channel side slopes and adjacent recontoured roadway areas that drain onto the stream channel side slopes using soil and vegetative transplants, native mulch, and certified weed free straw as necessary to obtain a minimum ground coverage of 95%.

(g) Treatment of ditch relief culverts. Treat ditch relief culverts as follows:

Remove vegetation and decompact the roadway in accordance with Subsections 211.03(a) and (b).

Remove the culvert and appurtenances in its entirety and dispose of by removal from National Forest land.

Perform the work required by Subsections 211.03(c) through 211.03(e).

(h) Treatment of seeps and wet areas. Treat seeps and wet areas as follows:

Remove vegetation and decompact the roadways in accordance with Subsections 211.03(a) and (b).

Shape the hillslope to drain water across the roadway. Rehabilitate all disturbed wet area and drain side slopes and adjacent recontoured roadway areas using soil and vegetative transplants, native mulch, and certified weed free straw as necessary to obtain a minimum ground coverage of 80%.
