106 - Acceptance of Work

106.01_nat_us_01_17_2013

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.

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:

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.

(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.

When required, 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.

157 - Soil Erosion Control

157.01_0618_us_02_03_2009

157.01 Add the following:

This includes protection of all phases of work during the life of the contract including storm events.

Materials

157.02 Add the following:

Coarse Aggregate for Concrete...…………………………………703.02

Watertight Gaskets………………………………………………..712.03

157.03 General. Add the following:

21 days prior to the start of construction, submit a written plan that provides specific sediment control measures to minimize delivery of soil and turbidity into the stream during the construction period including a channel diversion and dewatering plan if dewatering is required.

Include the sequence of operations and information on equipment, materials and suppliers.

Measures given in the Plans and Supplemental Specifications are minimum requirements, and may be revised only with written approval by the CO.

The turbidity of the water 100-200 feet downstream shall not be visually greater than the turbidity of the water upstream of the project site.

When this turbidity requirement or other erosion control measures are not met, immediately take corrective action. Cease operations that are causing turbidity and pump or otherwise improve the diversion of the stream around the construction site according to this specification and the Plans until the turbidity requirement can be met. When the interpretation of this requirement is in question, measure turbidity using a turbidity meter as approved by the CO, and provide documentation that operations are in compliance with FAR 52.236-7 Permits and Responsibilities, subsection 107.01 Laws to be Observed and subsection 107.10 Environmental Protection, and subsection 107.11, including but not limited to, the requirements of the National Marine Fisheries Service.

Do not begin work until the necessary controls for that particular phase of work have been implemented. Incorporate all erosion control features into the project at the earliest practicable time, as agreed by the CO.

Operate in a manner that will avoid harm to aquatic organisms whenever possible.

Notify the CO of the intention to dewater the stream, at least 10 days in advance. Do not re-route the stream until approved by the CO. The CO will not approve dewatering until a fisheries biologist and other Government personnel are present and prepared to rescue aquatic organisms.

Dewater the stream slowly and incrementally in order to facilitate the fish rescue. The rescue operation will generally take several hours.

Do not release water through the newly constructed simulated streambed until approved by the CO. After approval, release water slowly and incrementally over a period of at least one hour, or as approved by the CO. During this time, treat any water that does not meet the requirements of the turbidity standard stated in this specification.

157.04 Controls and Limitations on Work. Add the following:

Prior to construction, Contracting Officer will delineate critical riparian vegetation areas, wetlands, and other sensitive sites to prevent ground disturbance. Minimize disturbance to existing vegetation along stream.

Where necessary, danger tree removal may be required. Fell danger trees within riparian areas.

Where possible, fell trees towards the stream. Dispose of trees as directed by the Contracting Officer.

Confine work within the construction limits marked by the Contracting Officer. Use existing roadways or travel paths whenever reasonable. Minimize the number of new access paths.

Dispose of waste material at approved sites.

When erosion control materials are to be left on site after the project has been completed, construct erosion controls of organic and bio-degradable materials whenever possible.

157.04(b) Add the following:

For the work immediately adjacent to the stream, use sediment control barriers between the work and the stream. Place sediment barriers prior to construction around sites where significant levels of erosion may enter the stream directly or through road ditches.

Provide straw bales and silt fence for sediment control measures for each channel crossing being constructed concurrently. Use only as needed for sediment control or when specified by the Contracting Officer.

Provide waterproof membrane products to cover all stockpiled material adjacent to a live stream that is subject to erosion or water saturation. Cover stockpiles at the end of each work day and all day during the threat of precipitation or when specified by the Contracting Officer.

157.04(d) Delete the subsection and replace with the following:

Apply temporary turf establishment, mulch and stabilization measures on disturbed areas within three days of the last disturbance. Short-term stabilization measures may include the use of non-native sterile seed mix when native seeds are not available; weed-free certified straw, jute matting, and other similar techniques. Maintain short-term stabilization measures until permanent erosion control measures are effective.

157.04(f) Add the following:

When required by the Contracting Officer, loosen compacted areas, such as access roads, stream crossings, staging, and stockpile areas.

157.09 Diversions. Add the Following:

Construct stream diversion, related appurtenances and measures as follows:

(a) In Stream Work.

(1) Isolate construction area and coordinate with Contracting Officer for aquatic species removal by the Government. Coordinate aquatic species removal a minimum of 10 working days prior to beginning isolation of construction areas.

(2) Cease project operations under high flow conditions that inundate the project area, except for efforts to avoid or minimize resource damage.

(3) When approved, minimize time in which heavy equipment is in stream channels, riparian areas, and wetlands. Operate heavy equipment in streams only when Contracting Officer determines that such actions are the only reasonable alternative for implementation, or would result in less sediment in the stream channel or damage (short- or long-term) to the overall aquatic and riparian ecosystem relative to other alternatives.

(4) Clean and repair all equipment used in the in-stream work prior to entering the project area. Remove external oil and grease, along with dirt and mud, prior to construction. Inspect equipment daily for leaks or accumulations of grease, and repair any identified problems prior to entering streams or areas that drain directly to streams or wetlands.

(5) Fuel and service equipment used for in stream or riparian work in an approved staging area outside of riparian zone. When not in use, store vehicles in the staging area.

(b) Stream Bypass Dam and Pipe. Construct a dam of material handling bags, and bypass pipe as shown on the Plans or as approved by the CO. The mining of material from the streambed or floodplain to construct diversions is not permitted. If diversion allows for downstream aquatic species passage, (i.e., is not screened), place diversion outlet in a location to promote safe reentry of aquatic species into the stream channel, preferably into pool habitat with cover.

(1) Primary Bypass Dam. Construct the material handling bag dam in a dry condition by first pumping the stream around the dam. Place temporary cofferdams as needed. Remove rock and other irregularities from the streambed to form smooth bedding for the bypass dam. Place the dam so that water does not seep from the downstream side of the dam; if seepage occurs, improve the dam by adding bags, improving or adding seals, or other means to minimize seepage from the dam.

When it is impossible to eliminate seepage, construct a sump and pump clear water to the upstream side of the dam.

(2) Bypass Dam Impermeable Membrane. Place an impermeable membrane within or on the upstream side of the dam and entrenched in the streambed as shown on the Plans or approved by the CO. When approved by the CO, a small amount of granular bentonite may be used along the edges of the membrane to minimize seepage between the membrane and the streambed. Cut a hole in the membrane to fit the bypass pipe and seal the membrane to the bypass pipe or the bypass pipe collar using gaskets, adhesive strips or other approved methods.

(3) Bypass pipe. Place bypass pipe as shown on the Plans or approved by the CO.

Place the upstream invert of the pipe at the lowest point in the stream channel as practical. Install joints and elbows as shown on the Plans and as needed to accommodate the site layout. Use watertight seals meeting the requirements of Subsection 712.03. Do not place backfill until the pipe joints have been approved by the CO. Allow water to pass through pipe only after a downstream splash apron has been prepared in a manner that will protect the stream from scour and turbidity, and protect fish from harm. Construct the bypass in a manner that avoids injury to aquatic organisms.

(4) Material handling bags. Use only clean sand or coarse concrete aggregate in the bags. Loosely fill and tamp the bags in place to minimize seepage between, under, and around the bags.

(5) Bypass Pipe Collar. Install and maintain a leak-proof pipe collar as shown on the Plans or approved by the CO.

(6) Sediment Retention Pond. Provide a pond immediately downstream of the construction area capable of collecting and holding all seepage, drainage, and sediment not captured in stream diversion. Provide sufficient storing capacity to enable a sump pump to transfer the water, sediment and turbidity to a suitable treatment facility or area. Construct a downstream cofferdam to create a sediment retention pond when none is available immediately downstream of the project, when it is too small to use or to prevent water from entering the work area.

(c) Pumps. Install pumps as required to re-route stream around construction site and dewater foundations. When failure of a pump would result in movement of sediment or turbidity beyond the work area, provide a back-up pump that is readily available. When adjacent stream crossing projects are constructed concurrently, provide a minimum of one extra pump on site for the largest discharge site. Use the pumps for installing and removing the gravity bypass pipes and dams, at other times to facilitate construction operations, and during storms to supplement the gravity bypass. Pumps must have fish screens if used in streams where aquatic species are present and be operated in accordance with National Marine Fisheries Service (NMFS) aquatic species screen criteria. Equip the pump with approved screens, appropriate suction and discharge hoses, fittings and flow regulation equipment as needed. Insure that the pumps are clean, free of leaks and that the oil used as lubricant in the pump seal systems is food grade mineral oil. Install and operate pumps in a manner that will avoid impingement of small fish against the intake screens.

(1) Pump intakes. Use one of the following methods of screening on all draft hoses:

i. Perforated Plate; screen openings shall not exceed 3/32 or 0.0938-inches

ii. Profile Bar Screen; the narrowest dimension in the screen openings shall not exceed 0.0689-inches in the narrowest direction.

iii. Woven Wire Screen; screen openings shall not exceed 3/32 or 0.0938-inches the narrow direction.

Check intakes frequently and clean as needed with wire brushing, flushing, or any other acceptable method.

(2) Sump Pumps. Supply pumps capable of dewatering the structure foundation and sediment retention pond. Insure that pumps are clean and free of leaks. Remove sediment and turbidity in the Sump Pump discharge water prior to re-entering the stream.

(d) Sump Water Discharge. Discharge sump water as shown on the Plan or as approved by the CO. Apply one or more methods to remove sediment from sediment-laden water. Apply additional methods as needed to eliminate increase in downstream turbidity. Use the following methods as needed:

(1) Natural Vegetation/Soil Dispersal and Filtration. Discharge sump water onto areas of ground most advantageous for dispersal and filtration of sediment, e.g. flat heavily vegetated soil. When single point discharge does not function adequately, discharge water into a perforated pipe or series of pipes laid approximately level so that the brown water disperses over a wide area.

(2) Silt Bag Filtration. Discharge sump water into one or more silt bags. Silt bags are constructed of Mirafi 180N (or approved equal) with sewn seam strengths of 90% efficiency according to ASTM D4632. Construct bag to hold and filter sump water. Place silt bag(s) on level ground having layer of straw one foot thick minimum.

(3) Settling Basin. Discharge sump water into one or more basins. The basins may be pre-manufactured tanks, folding tanks, geotextile or membranes placed over a sandbag or weed-free straw berm, or other similar basins designed to separate sediment from the water.

(4) Suspended Sediment Coagulation Agent. When other methods do not function adequately, add an approved coagulation agent to water prior to discharging the water onto natural vegetation, silt bag, or settling basin. Use a flocculation agent such as Chitisan-based Storm-Klear Gel-Floc, or approved equal. Use suspended sediment coagulation agent according to manufacturer’s recommendations.

(e) Stream Re-Watering. Monitor downstream during rewatering to prevent stranding of aquatic organisms below the construction site. Ensure that concrete is sufficiently cured or dried before coming into contact with stream flow.

157.13 Maintenance & Cleanup. Add the following:

When removing sandbags, spread sand away from the waterway; if coarse concrete aggregate meeting the requirements of Subsection 703.02 is used in the sandbags, the gravel may be distributed evenly across the waterway.

Remove geotextile and other non-biodegradable materials used in dewatering and sediment control operations from Government property, unless otherwise approved by the CO.
