3. SCOPE OF WORK

a. The work to be accomplished is the cyclic maintenance, repair, and replacement of

Sloan’s Crossing Pond Boardwalk located at Mammoth Cave National Park, Mammoth Cave, KY 42259. This project consists of replacing, “in-kind”, 2,100 linear feet of wooden boardwalk (board width is approximately 5 ft with a surface area of 11,000 square feet.

The Contractor is responsible for verifying all dimensions. ATTACHMENT A represents the current condition (as a whole) of the boardwalk. Details of work:

1) Provide materials and services to remove and replace all wood decking, joists, 2” x

4” surface wood barriers and handrails and their components with new pressure-treated pine wood. Any wood that has direct contact with the ground or freshwater must be treated with Tenino Copper Naphthenate to include cut ends. All decking boards must be installed with a 1/8” gap between boards to allow for proper spacing for ventilation and drainage, following industry best practices and manufacturer instructions. Fasten the decking boards securely using Type 316 stainless steel screws. Inspect the newly installed decking to ensure proper alignment and structural integrity. All decking components, with the exception of the beams, will be replaced with the exact size (length, width, and height/thickness) of those that are being replaced.

2) Existing beams and footings shall be reused. The contractor shall perform a thorough inspection of the existing beams and footings to confirm the structural integrity and suitability for continued use in this project. The assessment shall consist of a visual inspection (looking for wood decay, insect damage, cracking, deformation, water damage, swelling, mold growth and any other signs of deterioration that may compromise the beams’ structural soundness). The Contractor will also verify that all connections tight and are free of rust or other signs of corrosion. If the contractor determines that any existing beams or footings are not structurally sound, they must notify the Contracting Officer (CO) and the Contracting Officer’s Representative (COR) and provide recommendations for appropriate replacement materials and methods. If the Contractor finds that the existing beams and footings are structurally sound, they may be reused in the renovated structure. The contractor shall ensure that the reused beams are properly installed, aligned, and fastened to footings and decking, following the International Building Code (IBC) and industry best practices.

3) No changes to the layout of the existing boardwalk and piers.

4) All work associated with this project must adhere to the International Building Code

(IBC).

5) Provide submittals for all materials. Additionally, submit a job specific Safety Plan. All submittals must be approved before the Notice to Proceed is issued by the CO.

6) It is highly encouraged that the Contractor conduct a site visit prior to starting this project.

4. CONTRACTOR USE OF SITE

b. Limit site disturbance, including earthwork and clearing of vegetation, to; 10 feet beyond surface walkways, patios, surface parking, and utilities less than 12 inches in diameter;

15 feet beyond primary roadway curbs and main utility branch trenches; and 25 feet beyond areas with permeable surfaces (such as pervious paving areas, storm water detention facilities, and fields) that require additional staging areas in order to limit compaction in the constructed area.

c. Confine deliveries and storage of materials to the parking lot at the entrance of Sloan’s Crossing Pond. The Contractor is liable for any damages to Federal property. The Contractor is solely responsible for the security of any equipment or materials left at the worksite unintended.

Do not use main roadways or entrances for parking or storage of materials. The visitor parking area at Sloan’s Pond will be used for any storage or parking vehicles as stated in paragraph 4c.
