Description of Work. The Contractor shall furnish all labor, materials, equipment, and supervision for site maintenance and minor construction of project areas within the Coronado National Forest.

The project areas are mine waste repository areas and former mine sites remediated under CERCLA Activities onsite will include soil decompaction, dry seeding, installing erosion control fabric, removal of existing fencing, and a mine feature closure.

Project Location.

There are three project areas, Lead Queen Mine, Marstellar Mine, and Blue Nose Mine.

Lead Queen: The Lead Queen Mine is located on the Coronado National Forest. Access to the Site is east from Tucson on Interstate 10 about 23 miles to Exit 281, and south on State Highway 83 for about 26 miles to State Highway 82 for 13 miles to the town of Patagonia. Take McKeown Avenue east near the Patagonia Post Office and the road turns into Harshaw Road. Travel south on Harshaw Road about 5.2 miles and turn right on Forest Road 4649. Take this road about 0.6 miles and turn right on Forest Road 4684. Take route 4684 about 1.5 miles and park the vehicle. Travel by foot about 0.4 miles over desert terrain to reach the north dump site. Roads are minimally maintained by the Forest Service and may only be accessed by 4-wheel drive vehicles.

The legal description is Township 22 S, Range 16 E, NW ¼ in Section 33. The latitude is 31.484815 and longitude is -110.718891.

Blue Nose Mine: Blue Nose Mine is located south of the Marstellar Mine approximately 800 feet west of Harshaw Road at latitude 31.448608, longitude -110.731460, and elevation of 5283 feet amsl. The Site is accessed via an 800-foot, decommissioned road. Before remediation, the mine consisted of six mine adits, one mine shaft and numerous tailings and waste rock stockpiles located adjacent or near the mine shafts and mine adits.

Marstellar Mine: The Marstellar Mine is located approximately 1,022 feet west of Harshaw road at latitude 31.454282632, longitude -110.732718839, and elevation 5,235 feet amsl. The Site is accessed via a 750-foot, decommissioned road that can be driven with a high clearance vehicle.

The decommissioned road has natural barriers like slash and logs in place to deter public access.

These barriers need to be moved for vehicle access. The barriers must be put back in place after on-site activities.

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, repair, or replace work that does not conform to the contract, or to prevailing industry standards where no specific contract requirements are noted. Removing, repairing, or replacing work; providing temporary traffic control; and any other related work to accomplish conformity will be 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.

d. Pipe- 2” diameter steel pipe; Refer to Illustration Removable Bar and Lock

The proposed design shall accommodate a typical adit with dimensions less than or equal to 6’x6’ but greater than 4’x4’. When building multiple grates in the same vicinity, the height of the upright footing and the length of the main crossbar shall be chosen so that the total amount of adjustment will accommodate the largest number of installations. However, the following design adjustments must be observed:

a . For main crossbar widths of 8’ a third upright assembly (upright footing and main upright) must be installed and for every additional 4’ in length thereafter b . For main crossbar widths of 8’ a third upright assembly (upright footing and main upright) must be installed and for every additional 4’ in length thereafter c . Main crossbars may extend in length of up to 8’. For main crossbars of 8 feet or greater, crossbars shall be constructed of 48” lengths joined at each upright assembly

d. Only one section of removable bar is required per installation

Upright assembly installation:

a. Determine the position of the upright footings and pre-drill holes for rock bolt installation. Rock bolt locations must be on the mine-side of the grate

b. Slide the main upright into the upright footing and stand the upright assembly in place

c. The main upright must be placed so that when the hangers are installed, they face into the mine and away from the portal

d. Bolt the upright footing to the floor using the lowest grate bar. Bolts should be placed on 1’ centers

e. Extend the main upright to the adit roof and locate the position of the rock bolt in the adit roof.

Lower the upright and drill the required hole

f. Extend the main upright to the roof and bolt in place. Then weld the flanges of the main upright to the sides of the upright footing

Crossbars installation:

a. Crossbars are to be welded to the main upright assembly

b. Cross bars must be placed to provide a 5 ¾” free space between the top of each cross bar and the bottom of the next

c. The spacing between the top bar and the adit roof may vary to accommodate the roof line but spacing must not be more than 8”. If spacing along the top for any interval greater than 1 ft is more than 8”, then a final crossbar must be installed to close the gap. Spacing between this crossbar and the last may be less than 5 ¾” to accommodate placement

d. Connections between the adit roof, rib and floor will be made by using 5/8” steel rods (“rock bolts”) anchored in at least 8” of competent rock. The rods may be press-fit or glued in place using a standard construction grade 2-part epoxy

e. The top, bottom, and every 5th crossbar assembly (main crossbar and spacers) must be bolted to the adit rib at both ends
