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.

Add the following:

Design and locate equipment repair shops, stationary refueling sites, or other facilities to minimize the potential and impacts of hazardous material spills on Government land.

Before beginning any work, submit a Hazardous Spill Plan. List actions to be taken in the event of a spill. Incorporate preventive measures to be taken, such as the location of mobile refueling facilities, storage and handling of hazardous materials, and similar information. The hazardous spill plan will describe how the contractor will comply with the following three methods to minimize fuel/oil leakage from construction equipment into the stream channel include the following:

i. All equipment used for instream work will be cleaned of external oil, grease, dirt and mud; and leaks repaired; prior to arriving at the project site. All equipment will be inspected by the Contracting Officer’s Representative before unloading at site. Any leaks or accumulations of grease will be corrected before entering streams or areas that drain directly to streams or wetlands.

ii. Equipment used for in-stream or riparian work (including chainsaws and other hand power tools) will be fueled and serviced in an established staging area (site-specifically recommended by COR). When not in use, vehicles will be stored in the designated staging area. The staging area should be in an area that will not deliver fuel, oil, etc. to streams.

iii. Oil-absorbing floating booms, and other equipment such as pads and absorbent “peanuts” appropriate for the size of the stream, will be available on-site during all phases of construction. For very small streams with few pools or slack water, booms may not be effective. More pads and straw bales to anchor booms may be necessary. Booms will be placed in a location that facilitates an immediate response to potential petroleum leakage.

Immediately notify the CO of all hazardous material spills. Provide a written narrative report form no later than 24 hours after the initial report and include the following:

· Description of the item spilled (including identity, quantity, manifest number, and other identifying information).

· Whether amount spilled is EPA or state reportable, and if so whether it was reported, and to whom. Federal and Idaho state regulations regarding spills will be followed: Any spills resulting in a detectable sheen on water shall be reported to the EPA National Response Center (1-800-424-8802). Any spills over 25 gallons will be reported to the IDEQ (1-800-632-800) (or Nevada equivalent), and cleanup will be initiated within 24 hours of the spill.

· Exact time and location of spill including a description of the area involved.

· Containment procedures.

· Summary of any communications the Contractor had with news media, Federal, state and local regulatory agencies and officials, or Forest Service officials.

· Description of clean-up procedures employed or to be employed at the site including final disposition and disposal location of spill residue.

When available provide copies of all spill related clean up and closure documentation and correspondence from regulatory agencies.

The Contractor is solely responsible for all spills or leaks that occur during the performance of this contract. Clean up spills or leaks to the satisfaction of the CO and in a manner that complies with Federal, state, and local laws and regulations.

151 – Mobilization 151_R04F12_4_26_2012

151.01 Description

Add the following:

This work consists of 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.

Wash the sides, tops, and undercarriages of all construction equipment. Perform all wor at a location designated on the plans or other locations approved in writing. Provide the CO with an opportunity to monitor the washing and inspection.

Remove all seeds, plants, plant fragments, dirt, and debris from the construction equipment. Only equipment cleaned and inspected 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 7 days before moving any construction equipment onto the National Forest, and at least 24 hours before changing locations within the project area. 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 C.O.

For work on national Forest System lands, use a washing system that traps all wash water and either stores it for removal from National Forest System lands or recycles the water for continued use. If the equipment recycles the water, provide adequate filters for seed removal. Dispose of the filter material and removed seeds offsite in a legal and approved manner. Do not mix soaps, detergents, or other chemicals with the wash water.

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, on 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.

Conform to the MUTCD and the following Sections and Subsections:

156.03 General

This contract will allow closure of the Warren profile Gap road #340 for two weeks during construction.

Note- There are homes beyond the Mayflower site at Trails End subdivision, and at Hettinger Ranch. The Warren Profile Gap road #340 also continues and eventually makes a loop to Big Creek and Yellowpine. Consequently traffic may come up from the other side of the Mayflower work site.

Unless otherwise provided for in Table 156-1, keep existing roads open to all traffic during road improvement work, and maintain them in a condition that will adequately accommodate traffic.

Perform no work that interferes or conflicts with traffic or existing access to the roadway surface until a traffic control plan has been approved. Post construction signs and traffic control devices in conformance with MUTCD. All required signs will be in place and approved prior to beginning work on project.

If the Contractor agrees in writing to allow public traffic to use a new road being constructed prior to completion, it will be considered an existing road for traffic control purposes.

156.04 Temporary Traffic Control.

Install and maintain temporary traffic control devices adjacent to and within the project as required by the approved traffic control plan and the MUTCD. Install and maintain traffic control devices as follows:

(a) Furnish and install traffic control devices before the start of construction operations.

(b) All detours outside of clearing limits will be approved in writing by the Contracting Officer as part of the traffic control plan.

(c) Install only those traffic control devices needed for each stage or phase.

(d) Relocate temporary traffic control devices as necessary.

(e) Remove devices that no longer apply to the existing conditions.

(f) Immediately replace any device that is lost, stolen, destroyed, or inoperative.

(g) Keep temporary traffic control devices clean.

(h) Remove all temporary traffic control devices upon contract completion or when approved.

(i) When required, use flaggers certified by the American Traffic Safety Services Association, the National Safety Council, the International Municipal Signal Association, a state agency, or other acceptable organization. Perform the work described under MUTCD Part 6. Use type III, VII, VIII, or IX retroreflective sheeting on flagger paddles. Do not use flags. Flaggers must wear high visibility safety apparel as required by MUTCD 6E.02.

156.05 Temporary Closures

Road segments shall be closed as shown in Table 156-1. The maximum consecutive days of closure shall be followed by a minimum number of consecutive days open to traffic as shown. Maintain traffic control devices during closure period(s). Appropriate barricades and signs will be erected and maintained as shown in the traffic control plan or as otherwise designated.

Prior to closing roads during construction, give written notice to the Contracting Officer at least 14 days in advance, so the CO can have the legal closure order signed by the Forest Supervisor.

Close road 50340 by providing and installing four Type III barricades with reflectorized panels meeting MUTCD standards.

Install the first and second Type III barricades at the excavation site (one on each side of the excavation site), with a sign mounted on the barricade that says in black letters on white background:

157 – Soil Erosion Control 157.03_nat_us_02_24_2005

157.03 General

Delete the entire subsection and replace with the following:

Prior to the start of construction, submit a written plan that provides permanent and temporary erosion-control measures to minimize erosion and sedimentation during and after construction. Do not begin work until the necessary controls for that particular phase of work have been implemented. Do not modify the type, size, or location of any control. Submit the erosion-control plan proposal to the Contracting Officer for approval at least 14 days before operations begin.

Incorporate all permanent erosion control features into the project at the earliest practicable time, as outlined in the approved plan.

When erosion control measures are not functioning as intended, immediately take corrective action.

57.03_R04F12__4_16_2009

This work also includes work according to FSSS 625, Turf Establishment.

The erosion control plan shall include all necessary measures to protect resources and Government improvements. The plan shall include, but is not limited to the following:

1. The construction activities and sequence of implementation relating to specific erosion control measures.

2. The location and type of PERMANENT controls to be implemented during construction.

3. The location and type of TEMPORARY controls to be implemented during construction.

157.03_R04F12_03_27_2012

4. For work in stream channels with running water a detailed dewatering plan. Water shall be conveyed around the construction area during the operating season and higher flows in the event of a storm. The dewatering plan shall state that the COR shall be notified at least 10 days in advance of any streamwork or dewatering. The COR will notify the District Fish biologist who will be available during dewatering to move fish from the dewatering area using a combination of dipnetting and electrofishing. The contractor shall schedule the start of dewatering to occur in the midmorning, so the fish crew will have the afternoon to remove the fish. After the COR approves the stream simulation placement ( with consultation of the Fisheries Biologist) the contractor shall rewater the area slowly in order to help the movement of fish.

157.03_0510_11_10_2004

In Mayflower Creek, the reconstructed stream channel will be “pre-washed” into a reach equipped with sediment capture devices such as Sedimat, prior to reintroduction of flow to the stream.

The construction site will be rewatered slowly to prevent loss of surface water downstream as the construction site streambed absorbs water and to minimize a sudden increase in turbidity.

In-channel sediment-abatement barriers such as Sedimat will capture sediment that is liberated during rewatering of dewatered channels, barriers will be appropriately cleaned out and removed, and captured sediment will be disposed of so it is not reintroduced into stream channels. Such barriers shall be maintained throughout the related construction and removed only when construction is complete and erosion control is assured.

5. The location of each temporary stockpile site for the excavated material, and location of erosion control measures to prevent sediment from washing off of stockpile.

6. A supply of erosion-control materials (e.g. silt fence, straw bales and/ or straw wattles) will be kept on hand to respond to sediment emergencies. Sterile straw or certified “weed-free” straw will be used to prevent introduction of noxious weeds.

Add to the third paragraph:

Upon completion of construction at the site, the Contractor shall remove all temporary dewatering materials and equipment from Government property. This includes items such as pumps, pipes and hoses, sand bags and Sedimat.

Add the following:

The Contractor shall adhere to the following practices:

a) In order to protect aquatic organisms, install screens on the intake of pumps with opening of 3/32 inch.

b) Centrifugal pumps used for removing water from structure excavation (if needed) shall sit in a secondary spill container with sufficient capacity to contain the quantity of fuel in the pump fuel tank.

c) Construct the Dewatering and Sediment Control according to the Contractor’s approved plan.

d) Maintain the roads and stockpiles of material in a manner that prevents direct entry of sediment into the stream, by either preventing the erosion of sediments or collecting the sediments before it reaches the stream.

e) Construct permanent and temporary control features to intercept sediments. A settling basin will be constructed, or a portable one used, that is able to handle the volume of water anticipated, and that provides filtering capability. Dewatering of the excavation site, (of ground water from the excavation) will be done by pumping water to the settling basin, and the basin shall be cleaned out when full of sediments.

f) Any sanitation facilities established by the Contractor shall be located as designated by the CO.

g) All project operations will cease, except efforts to minimize storm or high-flow erosion, under precipitation and high-flow conditions that result in uncontrollable erosion in the construction area.

157.13 Maintenance and cleanup

Delete the third paragraph and insert the following:

Erosion-control materials, such as hay bales, silt fences, and straw wattles will be removed by the Forest Service when the sites have revegetated. Any Sedimat used shall be removed from the stream channel by the contractor.

201.04 Clearing

Delete paragraph (c) and replace with the following:

(c) In areas outside the excavation, embankment, and slope rounding limits, cut stumps to within 12 inches or one-third of the stump diameter of the ground, whichever is higher, measured on the side adjacent to the highest ground.

Delete subsection (d) and replace with the following:

(d) Do not cut vegetation less than 3 feet tall and less than 3 inches in diameter, that is within the clearing limits but beyond the roadway and not in a decking area, and that does not interfere with sight distance along the road.

Add the following:

(e) Trim branches of remaining trees or shrubs to give a clear height of 14 feet above the roadbed unless otherwise indicated. Trim tree limbs as near flush with the trunk as practicable.

(f) Remove brush from log decks. Deck logs so that logs are piled parallel to one another; can be removed by standard log loading equipment; will not damage standing trees; will not interfere with drainage, and will not roll. Keep logs in log decks free of brush and soil.

Add the following:

Dispose of the existing culvert by method (a), remove from project The existing corrugated metal pipe culvert with concrete wingwalls and related appurtenances shall be removed and disposed of away from Forest land according to all applicable local, state, and federal regulations and 203.05(a). Temporary soil erosion control measures shall be in place prior to commencing.

203.05_nat_us_02_18_2005

203.05 Disposing of Material.

Add the following:

For Mayflower Creek box culvert, dispose of construction slash by method (l) placing slash on embankment slopes.

(e) Windrowing Construction Slash. Place construction slash outside the roadway in neat, compacted windrows approximately parallel to and along the toeline of embankment slopes. Do not permit the top of the windrows to extend above subgrade. Use construction equipment to matt down all material in a windrow to form a compact and uniform pile. 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.
