106.01 Conformity with Contract Requirements.

Delete Subsection 106.01 and substitute the following:

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 and replace work that does not conform to the contract, or to prevailing industry standards where no specific contract requirements are noted, 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

Install Temporary Culverts on Mendocino NF Page 18 of 60 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.

Take roadway cross-sections normal to centerline. When the centerline curve radius is less than or equal to 200 feet, take cross-sections at a maximum centerline spacing of 25 feet. When the centerline curve radius is greater that 200 feet take cross-sections at a maximum centerline spacing of 80 feet.

c) Slope Stakes & References:

Install Temporary Culverts on Mendocino NF Page 26 of 60

Replace section with the following:

Slope stakes and references. When required, locate slope stakes on designated portions of the road.

Locate the slope stake catch points and use them to establish clearing limits and slope stake references.

Mark slope stakes with the station, the amount of cut or fill, the horizontal distance to centerline, and the slope ratios.

Place slope reference stakes at least 10 feet outside the clearing limit and mark with the offset distance to the slope stake. Place sight stakes when required.

Prior to clearing and grubbing operations, move the slope stake outside the clearing limit to the slope reference stake. After clearing and grubbing and before excavation, reset the slope stakes in their original position.

Use the designated method to establish the slope stake catchpoint.

Method I—Computed Method. Use the template information shown in the plans or other

Government-provided data to calculate the actual location of the catchpoint. The slope stake

“catchpoint distance” provided may be used as a trial location to initiate slope staking. Recatch slope stakes on any section that does not match the staking report within the tolerances established in Table 152-2.

Method II—Catchpoint Measurement Method. Determine the location of slope stake catchpoints by measuring the catchpoint distances shown in the plans or other Government-provided data.

(d) Clearing and grubbing limits.

Add the following:

Establish clearing limits on each side of the location line by measuring the required horizontal or slope distances shown in the stake notes. Mark the clearing limits with flagging or tags on trees to be left standing, or on lath. Make markings intervisible, and no more than 90 feet apart.

After establishing clearing limits, move the location line stake outside the clearing limits for station identification purposes, and mark it with horizontal distance to location line

(e) Centerline reestablishment.

Replace with the following:

Reestablish centerline from instrument control points. The maximum spacing between centerline points is 25 feet when the centerline curve radius is less than or equal to 200 feet. When the centerline curve radius is greater than 200 feet, the maximum distance between centerline points is 80 feet.

(g) Culverts.

Replace subsection with the following:

Set culvert reference stakes at all culvert locations. Set a culvert reference stake on the centerline of the culvert 10 feet from each end or beyond the clearing limit, whichever is greater. Record the following on culvert reference stakes:

(1) Diameter, actual field measured length, and type of culvert.

Install Temporary Culverts on Mendocino NF Page 27 of 60

(2) The vertical and horizontal distance from the reference stake to the invert at the ends of the culvert.

(3) Station of actual point where culvert intersects centerline.

323 - Reestablishing Native Surface

323.00_01_us_10_12_2006

323.01 Work. This work consists of manufacturing cushion material on native surface roads with mobile rock processing equipment. The work includes reducing bedrock, where possible, and oversized rock to a specified size, watering, mixing, compacting, blading and shaping the manufactured cushion material into a smooth, non-segregated road surface as required by the design template.

303 – Road Reconditioning Include this specification with 323 – Reestablishing Native Surface

Construction Requirements

323.02 Processing. Reduce the native material to the maximum size and depth specified in the bid schedule by processing with equipment designed for that purpose over the entire roadbed.

Uniformly mix the fine and course particles of the cushion material across the road traveled way to eliminate localized pockets of open-graded rock.

No oversized rock or bedrock will be allowed within the specified depth of the material within the traveled way. Oversized material may be incorporated outside the traveled way so long as the required cross-section is maintained. Not more than 3% (by volume) of oversized material shall be sidecast in any 100 foot section except that NO material will be sidecast within 50’ of a live stream.

In limited situations, when shown on the plans, or in areas that cannot be processed to contract specifications, cover segments of the roadway with imported material. The material sources for the cover segments may come from adjacent road areas as marked, or approved by the Forest Service, or may come from a commercial source. After placing the imported material on the road surface, process, compact, and finish as required in Sections 323.03, 323.04, and 323.05.

323.03 Compaction. After development of the cushion material, uniformly crown, inslope, or outslope the traveled way and shoulders to the cross-section required. Compact the entire roadway by operating compaction equipment over the full width of the layer until visible displacement ceases. Make at least three complete passes.

323.04 Water. While compacting, blending and finishing ensure that the cushion material has sufficient moisture, either natural or added, to prevent segregation and facilitate compaction. A water source is shown on the plans.

323.05 Finishing. Ensure that the traveled way has a uniform grade and smooth surface free of hollows, depressions, and segregation. Do not leave berms or ridges along either shoulder of the roadbed, unless noted on plans or as marked on the ground by the engineer in the field. Ditches shall be cleared of any material that spills into their flowline so they will drain properly. Waste areas, borrow areas, and other areas disturbed by contractor activity shall be shaped to drain.
