106 - ACCEPTANCE OF WORK
106.01_nat_us_03_29_2005
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 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.

152 - CONSTRUCTION SURVEY AND STAKING
152.00_01_us_10_11_2006
Delete Section 152 in its entirety and replace with the following:
Description
152.01 This work consists of furnishing qualified personnel and necessary equipment and material to survey, stake, calculate, and record data for the control of work. See FAR Clause 52.236-17 Layout of Work.
Personnel, equipment, and material shall conform to the following:
(a) Personnel. Furnish technically qualified survey crews experienced in highway construction survey and staking. Provide personnel capable of performing in a timely and accurate manner.
An acceptable crew supervisor shall be on the project whenever surveying/staking is in progress.
Conduct construction staking under the direct supervision of a professional engineer registered for the state in which work is completed.
(b) Equipment. Furnish survey instruments and supporting equipment capable of achieving the specified tolerances.
(c) Material. Furnish acceptable tools, supplies, and stakes of the type and quality normally used in highway survey work and suitable for the intended use. Furnish stakes and hubs of sufficient length to provide a solid set in the ground with sufficient surface area above ground for necessary legible markings.
Use required stake dimensions and materials. Pre-paint the top 2 inches of all stakes and lath, or mark them with plastic flagging. Use designated colors for paint or flagging. Mark all stakes with a stake pencil that leaves a legible imprint, or with waterproof ink.
Do not use aerosol spray paints in the field. Provide for the safe storage use and clean-up of paint when on National Forest System Lands. Immediately report all spills to the CO, clean-up and disposal of spills and painting waste shall be in accordance with Federal state and local requirements.
Use moisture-resistant paper for survey notes. Keep notes in books with covers that will protect the contents and retain the pages in numerical sequence. At the conclusion of each road segment, the registered engineer shall affix the state authorized seal and sign all field books and drawings and attest in writing to the satisfactory completion of the project.
152.02 GENERAL When indicated on the plans, a preliminary survey line has been established on the ground. The project location line is established by offsets from this preliminary line. Data relating to horizontal and vertical alignment, theoretical slope stake catch points, and other design data will be furnished.
Before beginning construction, notify the CO of any missing initial reference lines, control points, or stakes. Reestablish missing reference, control lines, or stakes as necessary to control subsequent construction staking operations
Perform additional calculations for convenient use of Government-furnished data. Provide immediate notification of apparent errors in the initial staking or in the furnished data.
Preserve all initial reference and control points. After beginning construction, replace all destroyed or disturbed initial reference or control points necessary to the work.
Before surveying or staking, discuss and coordinate the following with the CO:
(a) Surveying and staking methods;
(b) Stake marking;
(c) Grade control for courses of material;
(d) Referencing;
(e) Structure control; and
(f) Any other procedures and controls necessary for the work.
Survey and establish controls within the tolerances shown in Table 152-1.
Prepare field notes in an approved format. Furnish all survey notes at least weekly. All field notes and supporting documentation become the property of the Government upon completion of the work.
Start work only after staking for the affected work is accepted.
The construction survey and staking work may be spot-checked for accuracy, and unacceptable portions of work may be rejected. Resurvey rejected work, and correct work that is not within the tolerances specified in Table 152-1. Acceptance of the construction staking does not relieve the Contractor of responsibility for correcting errors discovered during the work and for bearing all additional costs associated with the error.
Remove and dispose of all flagging, lath, stakes, and other staking material after the project is complete.
152.03 SURVEY AND STAKING REQUIREMENTS Perform all survey, staking, recording of data, and calculations as necessary to construct the project from the initial layout to final completion. Reset stakes as many times as necessary to construct the work.
(a) Control points Relocate initial horizontal and vertical control points in conflict with construction to areas that will not be disturbed by construction operations. Furnish the coordinates and elevations for the relocated points before the initial points are disturbed.
(b) Roadway cross-sections 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 than 200 feet, take cross-sections at a maximum centerline spacing of 80 feet. When the centerline curve radius is greater than 500 feet, take cross-sections at a maximum centerline spacing of 50 feet. Take additional cross-sections at significant breaks in topography and at changes in the typical section. Along each cross-section, measure and record points at breaks in topography, but no further apart than 20 feet. Measure and record points to at least the anticipated slope stake and reference locations. Reduce all cross-section distances to horizontal distances from centerline.
(c) Slope Stakes and References 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.
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 Set clearing and grubbing limits on both sides of centerline at roadway cross-section locations.
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 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.
(f) Grade finishing stakes Set grade finishing stakes, for grade elevations and horizontal alignment, on centerline and on each shoulder at roadway cross-section locations. Set stakes at the top of subgrade and the top of each aggregate course.
Where turnouts are constructed, set stakes on centerline, on each normal shoulder, and on the shoulder of the turnout. In parking areas, set hubs at the center and along the edges of the parking area. Set stakes in all ditches to be paved.
When the centerline curve radius is less than or equal to 200 feet, the maximum centerline spacing for stakes is 25 feet. When the centerline curve radius is greater than 200 feet the maximum centerline spacing for stakes is 80 feet. The maximum transverse spacing between stakes is 20 feet. Use brushes or guard stakes at each stake.
(g) Culverts Stake culverts to fit field conditions, the final locations may differ from the plans. 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.
(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.
Stake headwall for culverts by setting a hub with a guard stake on each side of the culvert on line with the face of the headwall. Perform this work after clearing is completed.
(h) Bridges Set adequate horizontal and vertical control and reference points for all bridge substructure and superstructure components. Establish and reference the bridge chord or the bridge tangent. Also establish and reference the centerline of each pier, bent, and abutment.
(i) Retaining walls Survey and record profile measurements along the face of the proposed wall and 5 feet in front of the wall face. Every 25 feet along the length of the wall and at all major breaks in terrain take cross-sections within the limits designated by the CO. For each cross-section, measure and record points every 25 feet and at all major breaks in terrain. Set adequate references and horizontal and vertical control points.
(j) Borrow and waste sites Perform the work essential for initial layout and measurement of the borrow or waste site. Establish a referenced baseline, site limits, and clearing limits. Survey and record initial and final cross-sections.
(k) Permanent monuments and markers Perform all survey and staking necessary to establish permanent monuments and markers. Set permanent monuments according to Section 621.
(l) Miscellaneous survey and staking Perform all surveying, staking, and recording of data essential for establishing the layout and control of the following, as applicable:
(1) Approach roads and trails;
(2) Curb and gutter;
(3) Guardrail;
(4) Parking areas;
(5) Paved waterways;
(6) Special ditches;
(7) Turf establishment;
(8) Utilities;
(9) Signs, delineators, and object markers; and
(10) Pavement markings.
(11) Cattleguards
(12) Drain Dips
(13) Erosion Control Measures
(m) Field Discrepancies Immediately notify the CO if a discrepancy is encountered between the plans and field conditions which affect the final road location. Prepare recommendations, in writing, to the CO for adjustments to the design to better fit field conditions. Affix the state authorized seal and sign the recommendation attesting to the adequacy of the adjustment. Ensure that adjustments to the design follow all applicable regulations and are consistent with design standards and criteria. Adjustments shall minimize construction effort, such as clearing and embankment volumes. Gain written approval of the adjusted design from the CO before incorporating such adjustment in the field. Return to the original design as soon as practical.

Submit an Erosion Control Plan detailing permanent and temporary control measures to minimize erosion and sedimentation during and after construction in accordance with the plans and storm water permits. Do not modify the type, size, or location of any control or practice without approval. Submit the erosion control plan proposal at least 7 days before operations begin to the CO for approval.
Reflect in the Erosion Control Plan special concerns and measures necessary to protect resources and government improvements. Include:
(a) The construction activities and sequence of implementation relating to specific erosion control measures.
(b) The location and type of permanent controls to be implemented during construction.
(c) The location and type of temporary controls to be implemented during construction.
(d) For work in stream channels with running water a detailed dewatering plan.

Upon completion of construction at the site, remove all temporary erosion control devices, dewatering materials and equipment from Government property.
157.06 SEDIMENT RETENTION STRUCTURES
Replace with the following:
Sediment basins (when required) may be excavated or geotextile sediment bag(s) may be used in accordance SCR 714.03. The size of geotextile sediment bag shall be 15’x 15’. Install geotextile sediment bag(s) on a slope so incoming water flows downhill through the bag without creating more erosion. Strap the neck of the geotextile bag tightly to the discharge hose. The outlet of the geotextile sediment bag(s) shall have riprap over geotextile fabric to prevent erosion. Sediment basins and geotextile sediment bag(s) shall be periodically relocated for construction operations or as directed by the CO. The contractor shall obtain data from the geotextile sediment bag and pump manufacturers to ensure they are compatible (i.e., the pump(s) providing the flow to the geotextile sediment bags does not produce a higher flow rate than the maximum rate which the geotextile sediment bag can filter and discharge). To increase the efficiency of filtration, the contractor may place the geotextile sediment bag(s) on an aggregate (crushed rock) base to maximize water flow through the surface area of the bag. The aggregate base, if installed, shall be removed with any relocation of the geotextile sediment bag or from National Forest lands upon conclusion of the dewatering operations. Sediment basin areas shall be reclaimed with grading, seeding and mulch, as required.
The geotextile sediment bag is full when it no longer can efficiently filter sediment or pass water at a reasonable rate. Flow rates will vary depending on the size of the geotextile bag, the type and amount of sediment discharged into the geotextile bag, the type of ground, rock or other substance under the bag and the degree of the slope on which the bag lies. Under most circumstances geotextile bag may accommodate flow rates of 1500 gallons per minute. Use of excessive flow rates or overfilling geotextile sediment bag with sediment may cause ruptures of the bags or failure of the hose attachment straps. Ruptured or disposed bags shall be replaced by the Contractor at no additional expense to the Government. Dispose geotextile bags as approved by the CO, off National Forest lands and in accordance with Federal, State, and Local laws.

157.10 WATERWAY AND SLOPE PROTECTION AND STABILIZATION
(e) Temporary slope drains
Replace with the following:
If dewatering is required, the pumped water discharge from dewatering activities shall not be allowed to flow overland back into the creek. Pumped water shall be treated by a sediment basin. Establish sediment sump to more sediment-laden seepage water from dewatered reach below construction area to a sediment basin >25 yards from stream in a flat area strewn with wood straw.
157.15 MEASUREMENT
Add the following:
Do not measure silt fence, sediment basins, or any other erosion control feature separately.
157.16 PAYMENT
