106 - Acceptance of Work

106.01_nat_us_07_31_2007

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.

This work also includes washing and treating construction equipment and vehicles necessary for equipment transport to remove seeds, plants, and plant fragments before the equipment is used on Forest Service lands, according to the requirements within.

Construction Requirements

Wash the sides, tops, and undercarriages of all construction equipment. Remove all seeds, plants, plant fragments, dirt, and debris from the construction equipment. Only equipment inspected by the Forest Service will be allowed to operate within the project area. All subsequent move-ins of equipment to the project area will be treated in the same manner as the initial move-in. This requirement does not apply to cars, pickup trucks, and other vehicles that regularly travel between the construction site and areas off the National Forest.

Equipment will be considered free of soil, seed, and other such debris when a visual inspection does not disclose such material. Disassembly of equipment, components or the need for specialized inspection tools is not required.

Notify the CO in writing at least 72 hours before moving any construction equipment onto the national forest. Notification will include an agreed upon location where the equipment will be available for inspection by the Forest Service. Inspection will be required after every cleaning.

Use methods of cleaning and locations for cleaning approved by the CO.

For work at a commercial washing facility, use an approved facility.

New infestations of noxious weeds of concern to Forest Service and identified by either Contractor or Forest Service, in the Project Area or on the haul route, will be promptly reported to the other party. Contractor and Forest Service will agree on treatment methods to reduce or stop the spread of noxious weeds when new infestations are found. A current list of noxious weeds of concern to Forest Service is available at each Forest Service office.

Measurement

151.02 Clean equipment prior to moving onto this project. The initial cleaning will not be included in the measurement for payment. Payment for cleaning will only be made if subsequent cleanings are ordered by the CO. Measurement shall be on an “each” basis, meaning one complete cleaning of all equipment required for this contract. Subsequent cleanings necessitated by the Contractor’s actions but not directed by the CO will not be included in the measurement for payment.

Measure mobilization according to Subsection 109.02.

Payment

152 - Construction Survey and Staking

152.01_0116_us_03_30_2005

Delete Section 152 and substitute the following:

Description

152.01 This work consists of completing the construction staking of a road project in accordance with the drawings and specifications. Furnish all labor, equipment, instruments, materials, transportation and record data necessary to complete the construction staking in accordance with these specifications.

Conduct construction staking under the direction of a licensed professional engineer or land surveyor who is closely associated and familiar with the project. Periodic visits to the project site are required.

At the conclusion of staking each road segment, have the registered professional engineer or land surveyor affix the state authorized seal and sign all fieldbooks and drawings and attest in writing to the satisfactory completion of the staking project.

Materials.

152.02

(a) Stakes. Prepaint the top 2-inches of all stakes and lath. Use approved colors for paint and flagging. Mark all stakes with a stake pencil that leaves a legible imprint, or with waterproof ink. Furnish wooden stakes with the nominal dimensions of 3/8” x 1-3/4”x 18” for guard, reference, slope and other stakes, lath with nominal dimensions of 3/8” x 1-3/4” x 36”and hubs with nominal dimensions of 1-3/4” x 1-3/4” x 3”. Use wire flags at least 16” in length with a minimum 9” square plastic flag secured to the top for markers.

(b) Survey Note Paper & Books. Furnish field notebooks or note paper. 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 during field use.

(c) Government-Furnished Documents. Drawings, P-line survey notes, construction staking notes and the projected location of catch points will be furnished by the Government. Return one set of “as staked” drawings and all documents to the CO.

Construction Requirements

(a) Precision. Accuracy and precision requirements are contained in tables 152-1 and 152-2. Ensure that all work performed under this specification meets the requirements of the survey precision designated in the bid schedule or shown in the plans.

152.03 Reestablishing Preliminary Survey Line. A preliminary survey line has been established on the ground for this project, with initial and specific succeeding survey points referenced. Reestablish missing P-line points as necessary to control subsequent construction staking operations to the precision designated in the bid schedule or shown on the plans.

152.04 Establishing Centerline. Establish the position of the centerline (L-line) by measuring right or left from the preliminary survey line (P-line) the horizontal distance shown in the “offset listing” furnished by the Government. Adjust the centerline established in alignment only to correct misalignment created by measured offsets along skewed sections. Ensure that the station of the centerline point is that listed in the P-line to L-line offset data.

Set additional intermediate centerline stakes at locations shown on the plans and listed in the construction staking notes, as needed to establish control for beginning and ending of extra widening and turnout tapers; for crest and sag of drainage dips; for culvert catch basins; and for turnarounds. Establish the position and ground elevation of these additional stakes by measuring from the nearest established centerline stake.

Where centerline stations fall in an existing trail, roadway, or obstruction, off set the stakes left or right from centerline (perpendicular to tangents and on the bisector of angle points) and the distance marked on the side of the stake facing centerline. Drive suitable markers on the centerline to denote actual centerline point.

Clear the survey line to facilitate surveying. Remove clearing slash from the travel or work area. Cut brush and trees as near to the ground as possible.

152.05 Vertical Control & “L” Profile Levels. Relocate bench marks that were established during the P-line survey within the clearing limits to points 20 feet or more outside the clearing limits. Determine elevation of relocated bench marks by the precision class specified, as listed in table 152-1.

Construct bench marks to be permanent and to allow a level rod to stand vertically and squarely on the mark. Bench marks may be established by driving a 40-penny or larger nail into a notch cut in the base of a tree, by marking a point on a stable rock, or by other approved means. Drive spikes into trees less than 12 inches above the ground. Record location and descriptions of relocated bench marks in the level notes.

Use appropriate survey equipment between bench marks to determine centerline ground elevations on L-line stations, to the nearest one tenth foot, and to verify bench marks.

For precision A,B,C and D, determine elevation of centerline stations by leveling from the listed elevation of the P-line station from which they were offset.

152.06 Discrepancies. Refer to the CO any differences that exceed 5 degrees of angle in horizontal alignment of curves with less than 100 foot radius found between the data shown on the plans and those observed on the ground. Compare the found centerline cut and fill depth with design data. Report differences in centerline profile elevations exceeding 1 foot at any two or more consecutive points to the CO, who will determine whether revision is needed. Defer staking of these areas until these differences are resolved by the CO.

Check horizontal distances on the centerline by measuring between stakes on L-line. If discrepancies in actual distances measured are greater than 5 feet, report them to the CO for possible corrective action.

152.07 Slope Stakes, Clearing Limits & Reference Points. Establish slope stakes, clearing limits and references at right angles to each centerline station listed in the construction staking notes. Slope stakes and references shall be set on the cut side only, except through cuts or through fills where both sides are staked and referenced. Establish clearing limits on both sides of centerline. Use a method to establish the slope stake catchpoint that conforms to the Method described below, as designated in the bid schedule.

(a) Method I – Computed Method. Locate slope stake catchpoints by using the template information shown in slope stake notes to calculate the actual location of the catchpoint. The slope stake “catchpoint distance shown in the stake notes may used as a trial location to initiate slope staking.

(b) Method II – Catchpoint Measurement Method. Locate slope stake catchpoints and clearing limits by measuring the “catchpoint distance” shown in the slope stake notes.

(c) Method III – Reestablishing Slope Stakes, Clearing Limits & References. Slope stakes and marks previously established for this project have either been destroyed or have become unreadable. Reestablish the missing stakes and marks from the original slope stake notes, as described in the Special Project Specifications.

Place a reference stake for each slope stake 10 feet outside the clearing limit as shown on the plans. Remove slope stakes to the reference stake prior to clearing and replace them after clearing is completed.

Locate clearing limits at the distance shown on the plans from either the slope stake catchpoint or road shoulder, whichever is greater. Mark clearing limits with plastic flagging or tags on trees to be left standing, or on lath.

152.08 Resetting Slope Stakes. Reestablish slope stakes after clearing and grubbing is completed and before excavation is started. Recheck the original catchpoint location from the reference stake to determine whether revisions are needed because of ground disturbance; recheck slope stakes and reset them to the original precision requirements.

152.09 Monuments of Property Boundaries or Surveys or Other Agencies. If property boundary or survey monuments or survey markers of other agencies are found within or adjacent to the construction limits; immediately notify the CO.

152.10 Staking Culverts. Stake culverts to fit field conditions. The location of culverts may differ from the plans. Perform the following:

(1)Determine the slope catch points for the catch basin (if applicable), the inlet and the outlet ends.

(2) 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 information necessary to determine culvert length, vertical and horizontal distance from the reference stake to the invert at both ends and stationing at centerline.

152.11 Staking 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, or abutment. Use hubs and tacks that are set on line beyond the construction limits as reference points, and mark them to identify the point and distance to the point referenced. Set at least one benchmark beyond project construction limits, but close enough to the bridge site to allow direct leveling between the benchmarks and the bridge without an intermediate setup. Record all of the above information in a separate book that includes a sketch showing the stream, bridge, and location of all construction stakes set.

152.12 Staking Retaining Walls. Set adequate horizontal and vertical control points at beginning and end of each mat along the wall face.

Provide offset stakes at every wall face stake. Offset stakes shall be located outside of any potential construction areas to ensure they are not damaged during construction. Offset stakes shall contain profile measurements, station location, and offset distance.

152.13 Marking Stakes. Legibly mark all stakes with a stake pencil that leaves an imprint or with waterproof ink.

152.14 Acceptance. Construction survey and staking will be evaluated under Subsections 106.02 and 106.04..

Measurement

152.15 Measure the Section 152 items listed in the bid schedule according to Subsection 109.02 and the following as applicable.

Reestablishing P-line includes all work needed to replace missing portions of the P-line that are necessary for the determination of L-line tangents. When listed in the bid schedule, the quantity is the number of miles of P-line reestablished, as measured along centerline to the nearest 15 feet. When the length of P-line to be replaced does not exceed 10 percent of the length of the P-line, reestablishing P-line is considered incidental to construction staking and no separate payment will be made.

Construction staking includes all work necessary to establish the project centerline and to establish slope stakes, clearing limits, and reference stakes in accordance with the method designated in the bid schedule. The quantity will be the number of miles of construction staking completed and accepted, to be measured along the centerline to the nearest 30 feet.

Payment

152.16 The accepted quantities, as provided above, will be paid at the contract price per unit of measurement for the Section 152 pay items listed in the bid schedule. Payment will be full compensation for the work prescribed in this Section. See Subsection 109.05.

At the prework meeting, or at least 7 days prior to the start of construction, submit a written plan for review and CO approval that provides permanent and temporary erosion control measures to minimize erosion and sedimentation during and after construction, including a dewatering and rewatering plan for work in live streams.

Include methods to minimize disturbance to streams and prevent runoff from the construction site entering directly into streams. The “Soil Erosion Control Plan” must address all construction activities that have the potential for stream sedimentation.

During construction, do not modify the type, size, or location of any accepted control or practice without 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 any stream channel (perennial or intermittent) provide a detailed dewatering and rewatering plan. Use the typical sheet in the Drawings as a guide for establishing a plan. Refer to section 157.09(a) for acceptable dewatering methods and section 157.09(b). for acceptable rewatering methods.

(e) The construction activities and sequence of implementation relating to specific erosion control measures.

Add the following to the third paragraph:

Upon completion of construction at the site, remove all temporary erosion control devices, dewatering materials and equipment from Government property.

157.08 Water Crossings.

Add the following:

At any channel crossing where there is running water, dewater and rewater by rerouting water flow around the site before and during excavation and embankment operations in accordance with subsection 157.09.

157.09 Diversions.

Delete and replace with the following:

Construct temporary channels, temporary culverts, or sandbags to divert water around disturbed areas and slopes. Earthen dams are prohibited. Use temporary channels, temporary culverts, pumps, sandbags, or other methods to divert the flow of live streams for permanent culvert installation and other work. Dewater and rewater as follows:

(a) Dewatering.

Excavation activities shall be in accordance with section 204.

(1) Stream Bypass Dam and Pipe or Channel. Construct a dam and bypass pipe to divert the stream water around the excavation. A channel lined with an impermeable membrane may be substituted for the bypass pipe when approved by the CO, however, a water crossing shall be constructed according to 157.08 whenever construction vehicles are crossing a live waterway.

(2) Sump Hole and Pumping. Construct a sump hole that will store enough water that over flowing does not occur. The sump hole shall be lined with an impermeable membrane. Install pump(s) as required to re-route stream around construction site or as a back-up method to collect seepage. When pumping is the primary diversion method, install a pump that has a pumping capacity greater than the flow of the stream. When failure of a pump would result in movement of sediment or turbidity beyond the working area, a back-up pump shall be readily available.

(b) Rewatering

When returning the live stream back into the original channel where construction activities have occurred provide one or more of the following measures to reduce sedimentation downstream:

(1) Washing. After placement of stream simulation material and before rewatering, wash the fines from the surface of the new stream bed. Capture these fines using silt fence, straw bales or other approved methods and remove from the stream channel.

(2) Sedimats. Place sedimats across the streambed as recommended by manufacturer or as approved by the CO. Remove the collected sediment from the stream channel.

(3) Sediment Dispersal and Filtration over Natural Vegetation. Install a temporary dam at the downstream end of the re-established stream channel that is sized to capture and contain all flow. Return stream flow to new channel to wash fines into dammed area. Pump all water with visible sediment to and area of natural ground of adequate vegetation to filter sediment from the water before it re-enters the stream in an undisturbed area.

Construct breaks of at least 15 feet at least every 200 feet in a windrow. Do not place windrows against trees. Obtain approval for pioneer roads. A pioneer road may be constructed to provide an area for placement of windrows, provided the excavated material is kept within the clearing limits and does not adversely affect the road construction.

(f) Scattering. Scatter construction slash outside the clearing limits without damaging trees. Limb all logs. Place logs and stumps away from trees, positioned so they will not roll, and are not on top of one another. Limb and scatter other construction slash to reduce slash concentrations.

(g) Chipping or Grinding. Use an approved chipping machine to grind slash and stumps greater than 3 inches in diameter and longer than 3 feet. Deposit chips or ground woody material on embankment slopes or outside the roadway to a loose depth less than 6 inches. Minor amounts of chips or ground woody material may be permitted within the roadway if they are thoroughly mixed with soil and do not form a layer.

(h) Debris Mat. Use tree limbs, tops, cull logs, split stumps, wood chunks, and other debris to form a mat upon which construction equipment is operated. Place stumps upside down and blend stumps into the mat.

(i) Decking Firewood Material. Remove brush from decks. Limb and deck logs that do not meet Utilization Standards according to Subsection 201.04 as directed by the CO. Cut logs to lengths less than 30 feet. Ensure that logs stacks are stable and free of brush and soil.

(j) Removal to designated locations. Remove construction slash to designated locations.

(k) Piling. Pile construction slash in designated areas. Place and construct piles so that if the piles are burned, the burning will not damage remaining trees. Keep piles free of dirt from stumps. Cut unmerchantable logs into lengths of less than 20 feet.

(l) Placing Slash on Embankment Slopes. Place construction slash on completed embankment slopes to reduce soil erosion. Place construction slash as flat as practicable on the completed slope. Do not place slash closer than 2 feet below subgrade. Priority for use of available slash is for: (1) through fills; (2) insides of curves; and (3) ditch relief outlets.

(m) Hydrological Sensitive Placement. Where required use this method in combination with other designated methods to dispose of material to reduce erosion and to aid in re-vegetation:

1. Place windrow segments on contours, wrap in type I geotextile.

2. Place logs as log erosion barriers on contours. Place logs so that 80% of their length is on the ground surface.

3. Scatter slash on bare or disturbed areas within or outside the clearing limits as directed.

4. Scatter chips or ground woody material on bare or disturbed areas within or outside the clearing limits as directed.

Place stumps in swales or on sites to form planting pockets. Place windrow segments on contours, wrap in type I geotextile.
