If any material is to be excavated or disposed of from any material source outside the construction limits, other than commercially available and operated sites, provide a

J-3 certification from the State Historic Preservation Officer or Indian Tribal Council, if applicable, before work begins that states:

(1) A cultural resource survey (a survey for historical sites and archeological remains) has been performed at the proposed site; and

(2) No significant cultural resources exist in the area that will be disturbed by the Contractor.

Section 107.—LEGAL RELATIONS AND RESPONSIBILITY TO THE PUBLIC

107.01. Add the following:

The following permits may be required for this project:

(a) Disposal permit or agreement.

(b) Erosion and sediment control.

(c) Hazardous waste permit.

This list of permits may not be all inclusive of those required for construction. No time or damages, including impact damages, will be allowed for failure to obtain necessary permits or agreements. Provide copies of these permits and agreements upon request.

107.02. Add the following after the third paragraph:

For the full duration of construction, do not disturb any vegetation or trees outside of the construction limits.

Tag trees that will be removed and obtain approval from the CO prior to removal. The CO will consult with the National Park Service (NPS) before providing tree removal approval.

Make restitution to the NPS for any trees damaged due to careless construction or inappropriate protection of existing trees. The amount of restitution for each tree will depend on the extent of damage.

Remove destroyed trees and make restitution for the loss of the trees. The value of the tree will be determined at $42.50 per square inch of trunk area (determined by diameter at 5 feet above the ground). A tree will be considered destroyed if any of the following apply:

• Any of the buttress root is debarked.

• 20 percent of the root protection area is impacted by equipment or stockpiled materials.

J-4

• Wound(s) to the tree trunk measure 20 percent or more of the total circumference of the tree.

If a tree is damaged, make restitution for the repair of the tree. The NPS will supply a resource management specialist to dress each wound. The cost will be determined at $50.00 per wound on the trunk below the 8-foot level and $80.00 per wound at and above the 8-foot level. A tree will be considered damaged if it suffers wounds to the trunk of less than 20 percent of the total circumference of the tree.

If any limbs or branches are broken or cut off without prior approval from the CO, make restitution for the repair. The NPS will supply a resource management specialist to prune and dress each wound. The cost will be determined at $75.00 per limb or branch.

Make restitution for the introduction of any exotic vegetation or pests introduced into the Park.

Examples include, but are not limited to, careless use of unclean equipment, incorrect seed mix, incorrect mulch or erosion control blanket, and/or unapproved sod. The amount of restitution will be based on the number of man-hours required to remove the exotic vegetation, or treat or eliminate exotic pests at $50.00 per man-hour and equipment rates will be assessed equal to commercial equipment rates within a 50 mile radius of the project site.

Restitution will be subtracted from the Contractor’s progress payments and will be unrecoverable.

107.08. Add the following:

Clean all equipment before entering Government property. This equipment will be subject to inspection at the CO’s discretion to preclude the introduction of exotic vegetation into the Park.

Make restitution for the removal of the exotic vegetation as described in this Section.

(i) Surface preparation. Prepare concrete surfaces to receive a penetrant sealer in accordance with these Specifications. Remove substances such as dust, grime, dirt, curing compound, form oil, stains, mineral deposits, oil, bituminous materials, debris and all other deleterious material by water blasting, wire brushing, or other methods acceptable to the CO, all in accordance with the penetrant sealer manufacturer’s recommendation.

Use approved water blasting equipment to clean existing concrete surfaces. Use water blasting equipment which is specifically manufactured to clean concrete surfaces. Use equipment that has a minimum rated nozzle capacity of 3,200 pounds per square inch using the spray head proposed for use in the work. Water used for blasting shall meet the requirements in Subsections 725.01(a).

During the cleaning operation, exercise sufficient care to minimize the removal of the concrete matrix. Furnish hand tools, power grinders, and other similar equipment to remove materials which cannot be removed by water blasting without abrading the concrete matrix beyond acceptable limits. Wash concrete surfaces cleaned by methods other than water blasting with water blasting equipment as the final cleaning operation.

Limit the duration of water blasting to provide a light abraded surface. Do not allow surface abrasion to exceed 0.016 inch. The CO will not require further cleaning of stains still apparent after abrading to a depth of 0.016 inch. Avoid exposure of coarse aggregate by water blasting.

Provide a surface finish to all concrete repair areas that matches the existing concrete in texture, color, and appearance.

Re-clean finished concrete surfaces which become contaminated before applying the penetrant sealer at no expense to the Government prior to applying the penetrant sealer.

(j) Application of sealant materials. Apply the penetrant sealer only to surfaces which have been prepared in accordance with these Specifications and approved by the CO. For application of the penetrant sealer, meet the Specifications and the penetrant sealer manufacturer’s recommendations. Prior to application of any penetrant sealer cure concrete for a minimum of 21 days. Coordinate the application of the penetrant sealer so that concrete surfaces prepared to receive penetrant sealer are sealed with the penetrant sealer within ten days after completion of the surface preparation and prior to contamination of the prepared surfaces.

Apply the penetrant sealer using any suitable air or airless sprayer with an operating pressure of approximately 20 pounds per square inch. Apply the penetrant sealer material only when the ambient air temperature is between 50° and 90° F. Apply the penetrant sealer only to concrete

J-8 surfaces which have dried a minimum of 48 hours after water last contacted the concrete surfaces. Do not apply the penetrant sealer when winds are blowing 25 miles per hour or more, during rainfall, or when water spray or mist is present.

Apply the penetrant sealer only to concrete surfaces that have been prepared in accordance with the requirements and limitations set forth in these Specifications. Determine the actual coverage rate in square feet per gallon on the basis of field trials. Conduct a field trial to determine the coverage rate at the beginning of any penetrant sealer application operation. For each field trial, determine the optimum coverage rate for 500 square feet of surface area. Maintain the penetrant sealer application rate between 155 and 225 square feet covered per gallon of penetrant sealer used. Apply the penetrant sealer in a uniform manner without pudding and skips. Redistribute any penetrant sealer which is applied and subsequently puddles in low areas over the concrete surfaces by use of a squeegee.

Generally, begin the application of the penetrant at the lowest elevation and proceed upward toward higher elevations.

Maintain operating pressures in the sprayers used for application of the penetrant sealer material sufficiently low so that atomization or misting of the material does not occur.

(k) Control of sealant materials. Deliver the penetrant sealer to the project in the unopened, sealed containers with the manufacturer’s label identifying the product and with numbered seals intact. Ensure that each container is clearly marked by the manufacturer with the manufacturer’s name and address, product name, date of manufacture, and expiration date.

Store materials delivered to the job site in original unopened containers within and appropriate storage facility. Use a storage facility that provides protection from the elements, and safe and secure storage of the materials. Do not return unused material in opened containers to storage for later use. The contractor may either apply such material to appropriate areas on concrete surfaces or remove and dispose of it at locations off site that the contractor supplies.
