Section 105. - CONTROL OF MATERIAL

105.01 Source of Supply and Quality Requirements. Add the following:

Transport import material directly from the source to Golden Gate National Recreation Area without intermediary storage or staging. Materials must also be transported and stored such that they will not acquire invasive non-native plant seeds from adjacent vegetation.

Non-native invasive plants, or noxious weeds, are species of plants that do not naturally occur in a particular area and have the potential to spread from their point of introduction into surrounding areas.

Obtain clearance or eradicate non-native plants by;

(1) Provide certification by a county extension agent, agronomist, or other qualified invasive species expert that the source is free from exotic plants; or

(2) Notify the CO at least 2 weeks before beginning operations at the source or starting crushing to allow for investigation by the NPS for exotic plants. If exotics are found, the CO will determine if the upper portion of the source will need to be stripped or sprayed with an herbicide approved by the CO. If spraying is required, provide a licensed operator to spray according to applicable state regulations. Do not spray any herbicides until approved in writing by the CO. Spraying or stripping of material does not necessarily constitute approval.

(3) If exotic plant clearance is not obtained, heat all material to 300 degrees Fahrenheit to ensure sterilization of any exotic plants before delivery of uncertified material. Do not stockpile the heated material outside the park boundaries prior to delivery. These requirements are waived if the contractor uses a source that meets the requirements stated in items (1) and (2) above.

Submit samples of materials for quality verification testing for materials required to conform to Sections 703, 704, and 705.

Materials containing petroleum-based solvents such as cutback asphalts and traffic paints may be restricted from use by local laws or ordinances in certain geographic areas. Upon presenting proof of such restrictions, alternate materials considered acceptable to the CO may be substituted for the materials specified in the contract.

105.02 Material Sources

(b) Contractor-located sources. Add the following to the end of the first paragraph:

For Contractor-located, non-commercial sources, secure environmental clearances according to Subsection 107.10.

E-5

Golden Gate National Recreation Area PMIS No. 88838

105.04 Storing and Handling Material. Add the following after the third sentence of the second paragraph:

For Contractor-located, non-commercial staging, storing, and material handling areas, secure environmental clearances according to Subsection 107.10.

Add the following:

Equipment and material staging areas will be located in existing disturbed areas within construction limits or previously approved areas. The Contractor may use the following for staging equipment and/ or storage of materials:

Smith Road (Maintain a 30 m buffer or protect with silt fence the riparian area near Smith Road (Park will flag the boundaries of the riparian area). Install silt fence at the edge of the staging area to delineate and protect.)

Julian Road parking area Point Bonita parking area Bicentennial (“Lower Fisherman’s) parking area Lanes that are closed to traffic during construction.

Large parking area/ disturbed area off of Bunker Road west of the Baker-Barry tunnel Battery Alexander parking area (Half of this parking area must be open to visitor parking on holidays and weekends with temporary fencing (temporary traffic control, plastic fence) placed around any equipment or material stored here.)

Allow 14 days for approval prior to using any other areas for staging or storing materials and/ or equipment. An asphalt batch plant will not be permitted in the park.

Cover all material stockpiles with a tarp that are left inactive during the rainy season, between November 1 and March 31.

Section 106. - ACCEPTANCE OF WORK

106.01 Conformity with Contract Requirements. Delete the text 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.

E-6

Golden Gate National Recreation Area PMIS No. 88838

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

(8) Validation process

E-7

Golden Gate National Recreation Area PMIS No. 88838

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.

Where sample/testing procedures make reference to AASHTO, ASTM, or other standards (designated as FLH T), the procedure as modified in the Materials Manual shall govern. Where the specifications make reference to AASHTO Test T11, “Procedure B - Washing Using a Wetting Agent” shall be the procedure followed.

Where the specifications make reference to AASHTO Test T310, “Direct Transmission Method of In-Place Nuclear Density and Moisture Content” shall be the procedure followed.

Reference to the Materials Manual means the Federal Lands Highway “Field Materials Manual, U.S. Department of Transportation, Federal Highway Administration,” Publication No. FHWA-FL- 91-002, dated January 2009, and all amendments and supplements thereto. Copies are available upon request by e-mail to CFLContracts@fhwa.dot.gov, by fax to 720-963-3360 or on our website at www.clfhd.gov/materials.

Modify the erosion and sediment control details, layout sheets, and quantities included in the plans if necessary to address project site conditions and proposed construction operations and include them in the SWPPP.

To comply with the General Permit, jointly review the draft SWPPP with the CO and agree to any needed revisions. Jointly approve and sign the revised SWPPP. The approved SWPPP will describe and ensure the implementation of practices, which will be used to reduce the pollutants in storm water discharges to assure compliance with the terms and conditions of the General Permit.

When the SWPPP is approved and signed by the CO and Contractor, it will be the document in force on the project. Implement the SWPPP as required throughout the construction period.

Place the SWPPP and all updates in a three-ring binder so that completed inspection forms and other records may be inserted. Maintain a current copy of the SWPPP, including a copy of the permit, NOI, Waste Discharge Identification (WDID), and all associated records and forms at the job site throughout the duration of the project. Make the SWPPP available for public inspection and for the inspection and use of the CO.

Maintain all related erosion control elements in proper working order throughout construction.

Ensure erosion control measures are in place prior to construction activities and in good repair by October 15 each year. Do not perform clearing and grubbing or earthwork until the SWPPP has been implemented.

Prior to construction, the Contractor and all subcontractors must sign certifications (included in the SWPPP) that they understand the requirements of the General Permit. Ensure that all subcontractors comply with the requirements of the General Permit.

At the completion of the project, provide the CO with the SWPPP, including inspection forms and all data used in developing and modifying the SWPPP. The Contractor is also required to retain a copy for a period of at least three years from the date the site is finally stabilized.

Do not discharge these materials into channels leading to any stream, lake or reservoir.

Locate machinery servicing and refueling areas away from streambeds and washes to reduce the possibility and minimize the impacts of accidental spills or discharges.

Remove non-waste materials, such as used cans, oils, machine and equipment parts, paint, hazardous materials, plastic and rubber parts, discarded metals, and building materials from the construction site and dispose of at an approved landfill.

Where the Contractor’s working area encroaches on a running or intermittent stream, construct and maintain adequate barriers to prevent the discharge of any contaminants into the stream.

Do not operate mechanical equipment in running streams unless approved in writing by the CO.

Fording of running streams with construction equipment will not be permitted. Obtain approval from the CO to use temporary bridges or other structures whenever crossings are necessary.

Immediately clear streams, lakes and reservoirs of all work items, debris or other obstructions inadvertently placed thereby or resulting from construction operations.

E-14

Golden Gate National Recreation Area MIS No. 88838

(g) Inspections and Revisions to the SWPPP. Conduct inspections before and within 24 hours after storm events and once each 24-hour period during extended storm events. Conduct a minimum of one site inspection per month for areas that receive less than 510 millimeters (20 inches) of annual rainfall. Inspection frequency can be reduced to one per month if: 1) the site is temporarily stabilized, 2) runoff is unlikely due to winter conditions (site is covered with snow, ice, or the ground is frozen, or 3) during seasonal arid and semi-arid periods (areas with an average rainfall of 510 millimeters (20 inches) or less). Conduct a minimum of one site inspection every seven calendar days where the mean annual rainfall equals 510 millimeters (20 inches) or more. The area of inspection includes, but is not limited to, disturbed areas that have not been finally stabilized, areas used for storage of materials, locations where vehicles enter or exit the site, and all of the erosion and sediment controls that are included in the SWPPP. Monitor rainfall with a rain gauge accurate to the nearest 13 millimeters (0.5 inches) of rain.

Document the inspections on forms provided in the SWPPP. Be consistent with the State Water Quality Control Board inspection forms, and sign according to the requirements of the SWPPP and the General Permit. Retain inspection forms onsite in the SWPPP notebook throughout the construction period.

Revisions to the SWPPP may be necessary during construction to make improvements or to respond to unforeseen conditions noted during construction or site inspections. For that purpose, specify in the SWPPP the mechanism whereby revisions may be proposed by the Contractor or the CO and incorporated into the plan, including review and approval of minor changes. Jointly approve and sign each revision to the SWPPP before implementation. Implement approved modifications within 7 calendar days following the date of the inspection when deficiencies or necessary corrections were first noted.

107.02 Protection and Restoration of Property and Landscape. Add the following:

Protect historic batteries, bunkers, tunnels, and related features, and existing concrete curbs, gutters, and sidewalks, from damage including asphalt and emulsion overspray. If needed use protective covers to protect the adjacent features.

107.05 Responsibility for Damage Claims. Delete the first paragraph and insert the following:

Indemnify and hold harmless the Government, the California Department of Transportation, and the Golden Gate Bridge, Highway, and Transportation District, their directors, officers, employees, agents, and consultants from suits; actions; or claims brought for injuries or damage received or sustained by any person, persons, or property resulting from the construction operations or arising out of the negligent performance of the contract.

107.08 Sanitation, Health, and Safety. Add the following:

There will be considerable contact with poison oak during construction. Implement appropriate protection measures when working in or around poison oak.

107.10 Environmental Protection. Delete the text and substitute the following:

(a) Spills of Petroleum Products or Hazardous Materials. Properly clean up, mitigate, and remedy, if necessary, all spills of petroleum products, hazardous materials, or other chemical or biological products released from construction, fleet, or other support vehicles, or stationary sources. Respond in accordance with federal, state, and local regulations.

Immediately report to the CO any spill of petroleum products or a hazardous material. Report the spill to the appropriate federal, state, and local authorities, if the spill is a reportable quantity.

(b) Water pollution. Do not operate mechanized equipment or discharge or otherwise place any material within the wetted perimeter of any waters of the U.S. within the scope of the Clean Water Act (33 USC § 1251 et seq.). This includes wetlands unless authorized by a permit issued by the U.S. Army Corps of Engineers according to 33 USC § 1344, and, if required, by any State agency having jurisdiction over the discharge of material into the waters of the U.S. In the event of an unauthorized discharge:

(1) Immediately prevent further contamination;

(2) Immediately notify appropriate authorities; and

(3) Mitigate damages as required.

Comply with the terms and conditions of any permits that are issued for the performance of work within the wetted perimeter of the waters of the U.S.

Separate work areas, including material sources, by the use of a dike or other suitable barrier that prevents sediment, petroleum products, chemicals, or other liquid or solid material from entering the waters of the U.S. Use care in constructing and removing the barriers to avoid any discharge of material into, or the siltation of, the water. Remove and properly dispose of the sediment or other material collected by the barrier.

E-20

Golden Gate National Recreation Area MIS No. 88838

(c) Vehicles and equipment. All vehicles and equipment entering the project area must be clean of noxious weeds and free from oil leaks and will be inspected prior to entering the project. Wash all construction equipment to thoroughly remove all dirt, plant, and other foreign material. Particular attention must be shown to the under carriage and any surface where soil containing exotic seeds may exist. These efforts are critical to prevent the introduction and establishment of non-native plant species into the project area. Make arrangements for the CO to attend each inspection on each piece of equipment before entering the project. The Contractor will maintain records of all inspections. Equipment found operating on the project that has not been inspected, or has oil leaks will be shut down and subject to citation.

In general, when gasoline, diesel fuel, antifreeze, hydraulic fluid or any other chemical contained within the vehicle is released to the pavement or ground, proper corrective, clean-up, and safety actions specified in the SWPPP must be immediately implemented. All vehicles with load rating of 2 tons or greater should carry, at minimum, enough absorbent materials to effectively immobilize the total volume of fluids contained within the vehicle.

Repair oil leaks immediately on discovery. Do not use equipment that is leaking. Have oil pans and absorbent material in place prior to beginning repair work. Have the “on scene” capability of catching and absorbing leaks or spillages of petroleum products including antifreeze from breakdowns or repair actions with approved absorbent materials. Keep a supply of acceptable absorbent materials at the job site in the event of spills, as defined in the SWPPP. Sand or soil are not approved absorbent materials.

Use oil pans and absorbent materials to prevent leaks, spills and draining petroleum fluids from falling onto bare ground and paved surfaces during servicing of equipment. Dig up soils contaminated with such fluids, place in appropriate safety containers, and dispose of according to state and/or federal regulations.

(d) Environmental Clearances.

(1) Contractor-Selected, Non-Commercial Areas. Contractor-selected, non-commercial areas include, but are not limited to, material sources, disposal sites, waste areas, haul roads, and staging areas. (A commercial source is a current operating concern, which has in the recent past provided same-type materials or services). These requirements do not apply for areas identified by the FHWA as having previously received clearance.

Prior to construction activities in Contractor-selected, non-commercial areas, provide the following to the CO and the FHWA Environmental Section (12300 West Dakota Avenue, Lakewood, CO 80228/Fax 720-963-3610):

(a) A report with documentation, according to the Secretary of the Interior’s Standards and Guidelines for Archeology and Historic Preservation, to determine if prehistoric or historic buildings, structures, sites, objects, or districts listed or eligible for listing in the National Register of Historic Places (NRHP) are present and if they will be affected by the proposed

E-21

Golden Gate National Recreation Area MIS No. 88838 activity. Include information identifying the location, total land area, and type of activity proposed. The FHWA will review this documentation. The FHWA will coordinate with the State Historic Preservation Officer (SHPO) and other parties, which will require the following time frames:

(1) Coordination on a “no effect” determination may require 30 days or longer.

(2) Coordination on eligibility and affects may require 45 days or longer.

(3) Coordination on mitigation of adverse effects may require 60 days or longer.

(b) Written documentation that such activities will not affect any “Waters of the U.S.” as defined by the U.S. Army Corps of Engineers. Provide documentation by an individual capable of performing wetland delineations according to the 1987 Corps of Engineers’ manual. Documentation of effects to wetlands or other Waters of the U.S. will be submitted to the CO and to the FHWA Environmental section. If wetlands are affected, coordination with the Corps of Engineers may require 45 days or longer.

(c) Written documentation that such activities will not affect any species protected under the Endangered Species Act (ESA). Provide documentation prepared by a biological specialist.

The written documentation will include a “no effect,” a “may affect-is not likely to adversely affect,” or a “may affect-is likely to adversely affect,” determination according to Section 7 of the Endangered Species Act. Submit the documentation to the CO and the FHWA Environmental Section. If the determination is “may affect-is not likely to adversely affect” or “may affect-is likely to adversely affect,” the FHWA will coordinate with the U.S.

Fish and Wildlife Service (FWS), which will require the following time frames:

(1) “May affect-is not likely to adversely affect” may require 45 days or longer.

(2) “May affect-is likely to adversely affect” may require 150 days or longer.

Contract time will not be increased due to the submittal and approval process for the above three items.

(e) Air Pollution. The following basic control measures for construction emissions of PM10 (Bay Area Air Quality Management District 1999) will be implemented at all construction sites:

All active construction areas will be watered to control dust.

All trucks hauling soil, sand, and other loose materials will be covered, or all trucks will be required to maintain at least 0.6 meters of freeboard.

All paved access roads, parking areas, and staging areas at construction sites will be swept (where required and necessary).

Streets will be swept as required (with water sweepers) if visible soil material is carried onto adjacent public streets at no cost to the government.

E-22

Golden Gate National Recreation Area MIS No. 88838

(f) Noise. The following basic control measures to control noise will be implemented at all construction sites:

Equipment and trucks used for construction will utilize noise control techniques, including original mufflers, intake silencers, ducts, engine enclosures and acoustically attenuating shields or shrouds.

All equipment and construction vehicles must meet federal standards for the year they were built and must be properly maintained and equipped with exhaust mufflers that meet state standards.

Construction equipment shall not idle for long periods of time.

Impact tools used for construction will be hydraulically or electrically powered wherever possible to avoid noise associated with compressed air or exhaust from pneumatically powered tools.

When a pneumatically powered tool must be used, an exhaust muffler on the compressed air exhaust will be used.

External jackets on the tools will be used where feasible.

Section 108. - PROSECUTION AND PROGRESS

108.01 Commencement, Prosecution, and Completion of the Work: Add the following:

Complete all work for Schedules A, B, and C by September 16, 2011.

Prior to beginning work, the Contractor must attend a project orientation conducted by Golden Gate National Recreation Area to learn about the sensitivity of the Park, Park regulations, and best management practices while working in the Park.

There is a potential for the presence of Unexploded Ordinance (UXO) within Golden Gate National Recreation Area from former Army bases and routine training. In the event the Contractor uncovers UXO the Contractor shall cease work in the affected area, remove personnel from the affected area, and notify the CO immediately. The Contractor may resume work only upon authorization by the

CO.
