106 - Acceptance of Work

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 restrictive.

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. Three methods of determining conformity and accepting work are described in Subsections 106.02 to

106.04 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 resolve the dispute, further evaluation may be obtained by written request. Include

Willow Creek Bridge #1 GMUG NFs - Gunnison RD

ATTACHMENT 1

MODIFICATION 1

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.

Contractor or Forest Service, on the Project Area or on the haul route, shall be promptly reported to the other party. Contractor and Forest Service shall agree on treatment methods to reduce or stop the spread of noxious weeds when new infestations are found.

107.11 Protection of Forests, Parks, and Public Lands:

Fire Precautions. Specific fire precautionary measures listed below shall be applicable during

Contractor’s Operations in “Fire Precautionary Period” described as between June 1st and August

31st. Contracting Officer may change the dates of Fire Precautionary Period by advance written notice, if justified by unusual weather or other conditions. Required tools and equipment shall be kept in serviceable condition and immediately available for fire fighting at all times during

Contractors Operations in Fire Precautionary Period.

Substitute Precautions. Forest Service may authorize substitute measures or equipment, or waive specific requirements by written notice, if substitute measures or equipment will afford equal protection or some of the required measures and equipment are unnecessary.

Willow Creek Bridge #1 GMUG NFs - Gunnison RD

ATTACHMENT 1

MODIFICATION 1

Emergency Precautions. Forest Service may require the necessary shutting down of equipment on portions of Contractor’s Operations, as specified by the emergency fire precautions as listed below.

Fire Control. Contractor shall, both independently and in cooperation with Forest Service, take all reasonable and practicable action to prevent and suppress fires resulting from Contractor’s

Operations and to suppress any forest fire in the project area. Contractor’s independent initial fire suppression action on such fires shall be immediate and shall include the use of all necessary personnel and equipment at Contractor’s disposal on site.

Fire Suppression Costs. Contractor’s obligations for cost of fire suppression vary according to three classifications of fires as follows:

Operations Fire. An “Operations Fire” is a fire caused by Contractor’s Operations other than a Negligent Fire. Forest Service shall under 16 USC 572, perform fire suppression activities on Operations Fires. Contractor agrees to reimburse Forest Service for such cost for each Operations Fire, subject to a maximum of the cost to suppress the fire.

Negligent Fire. A “Negligent Fire” is a fire caused by negligence or fault of Contractor’s

Operations, including, but not limited to, one caused by smoking by persons engaged in

Contractor’s Operations during the course of their employment, or during rest or lunch periods; or if Contractor’s failure to comply with the fire prevention requirements results in a fire starting or permits a fire to spread. Damages and the cost of suppressing Negligent Fires shall be borne by Contractor.

Other Fires on Construction Project Area. Forest Service shall pay Contractor, at fire fighting rates common in the area or at prior agreed rates, for equipment or personnel furnished by Contractor at the request of Forest Service, on any fire on Project Area other than an Operations Fire or a Negligent Fire.

Other.

1. Smoking and Lunch Fires. Smoking is prohibited except inside a building, developed recreation site, vehicle, or while seated in an area of at least three feet in diameter that is barren or cleared of all flammable materials. 36 CFR 261.52(d).

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 50 feet.

(d) Slope and reference stakes:

Replace section with the following:

(d) Slope stakes and references. (2) Conventional Survey Methods 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.

Willow Creek Bridge #1 GMUG NFs - Gunnison RD

ATTACHMENT 1

MODIFICATION 1

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.

(e) Clearing and grubbing limits.

Add the following:

Establish clearing limits on each side of the horizontal control line (HCL) 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 (road centerline) stake outside the clearing limits for station identification purposes, and mark it with horizontal distance to location line (road centerline)

(g) Culverts.

Delete this section

(h) Bridges.

Replace the subsection with the following:

Set adequate horizontal and vertical control, reference lines, and reference points for the bridge, abutment footings, abutment bearing seats, wing walls, and other major components. Establish the bridge control, reference lines, and reference points by setting hubs and guard stakes beyond the clearing limits on each side of the channel. Record the following reference stakes:

(1) Station or coordinates of actual point where the abutment centerline of bearing intersects the road centerline and the skew angle;

(2) Reference points and lines for the location of both footings including footing elevations;

(3) Reference points and lines for wingwalls and abutment walls locations including all elevations shown on the plans;

(4) Reference points and lines for all top of embankment stations and offsets;

(5) Reference points, offsets and lines for approach rail posts;

(6) Riprap coordinates and elevations, and;

(7) Reference lines, aggregate thicknesses, and grade of surface aggregate.

Perform this work after clearing is completed and within the tolerances established in Table 152-1. The structural component’s control is established as a local network and the tolerances are relative to that network.
