A. Project Location: 100 National Park Road, Hopkins, South Carolina 29061. The boardwalks are located near the Harry Hampton Visitor Center and accessible from the main Park entrance off of Old Bluff Road.

B. The Work consists of:

1. This project will remove and replace the elevated and low floodplain boardwalks behind the Visitor Center. The boardwalk is within Wilderness boundaries and all work will comply with the Wilderness Act. The existing wooden boardwalk will be removed and replaced with more substantial material. New boardwalks will meet Architectural Barriers Act Accessibility Standards (ABAAS). The current boardwalk is located at an elevation that floods six to ten times a year. As a result, the surface is often slippery and uneven and does not meet current ABA and universal design standards.

2. The project will remove and replace Boardwalks B, D, & F as shown on the plans.

Approximate boardwalk lengths are below:

a. Boardwalk Section B: 2435 LF

1) Existing boardwalk transitions from an elevated boardwalk from boardwalk A/G to a low boardwalk at boardwalk C (See existing survey). Existing boardwalk to be removed complete, including wood column supports. New boardwalk to be built in the same or similar footprint.

b. Boardwalk Section D: 1100 LF

1) Boardwalk transitions from a low boardwalk from boardwalk C to an elevated boardwalk at boardwalk E (see existing survey). Existing boardwalk to be

Congaree - 248643 01 11 00 - 2 removed complete, including wood column supports. New boardwalk to be built in the same or similar footprint.

c. Boardwalk Section Weston Lake: 280 LF with 10'X10" gathering area at the end.

1) Boardwalk section is new and does not require demolition.

d. Boardwalk Section E Overlook

1) Boardwalk overlook to be removed complete & replaced. Existing boardwalk is elevated (See survey)

e. Boardwalk Section F: 306 LF

1) Existing low boardwalk (See existing survey). Existing boardwalk to be removed complete, including wood column supports. New boardwalk to be built in the same or similar footprint.

f. Boardwalk Section A

1) Existing boardwalk to remain. Scope includes adding lights to existing boardwalk.

C. Project will be constructed under a single prime contract.

1.3 WORK PHASES

A. As there are multiple sections of boardwalk being demolished and constructed, phasing will be utilized to access to Westin Lake & the Overlook remains open for visitors. The Work shall be conducted in phases. The order and schedule of the phases will be the responsibility of the contractor.

B. NPS anticipates no more than 2 boardwalk sections will be closed at one time. If at any time contractor exceeds this, Contractor shall notify NPS for approval.

C. Contractor shall provide a phasing plan for work on impacted boardwalks and integrate this plan into the schedule.

1.4 WORK UNDER OTHER CONTRACTS

A. General: Cooperate with separate contractors so work on those contracts may be carried out smoothly, without interfering with or delaying work under this Contract. Coordinate Work of this Contract with work performed under separate contracts.

B. Concurrent Work: Government may award separate contract(s) for construction operations at Project site. Those operations will be conducted simultaneously with work under this Contract but are not anticipated to interfere with the Contract Work.

1.11 Work restrictions along boardwalk areas designated as Congaree Wilderness:

A. The General Contractor will be required to coordinate with NPS on minimizing the use of power tools and transportation with the Designated Wilderness.

B. The following is an excerpt from the Wilderness Minimum Requirements Analysis for Large Scale Replacement of the boardwalk in the Congaree Wilderness:

1. This alternative allows the use of both traditional and non-traditional tools to preform normal operations and maintenance, repair of damage to the boardwalk, and the management of trees/limbs in the boardwalk corridor (Boardwalk corridor: The boardwalk footprint, extending 3 feet to either side of the finished boardwalk width) that interfere with boardwalk operations and maintenance and repair. In addition, it includes non-motorized cart access to the site, designated staging areas within wilderness, movement of materials and debris on the boardwalk, along Sims Trail, and within the boardwalk corridor.

2. Although a high priority will be placed on the use of traditional tools when possible, this alternative allows for the routine use of non-motorized wheeled carts to transport tools and materials on the boardwalk and on Sims Trail, portable gas-powered electric generator (60dB maximum), both battery and electric operated power tools and chainsaws, and gas operated

Congaree - 248643 01 11 00 - 6 power tools and chainsaws in a limited capacity. Any continuous run tool will be turned off when not in use.

3. Risk Management and Timing: Repairs will be performed in a manner that will reduce closure time and minimize hazard exposure, in turn increasing visitor satisfaction while reducing risk and liability. Repair schedule will also consider times that least effect/disrupt visitors, wildlife, and/or other park operations.

4. Noise Pollution: Anytime power tools are to be used, the quietest tool suitable for the task will be used (Example; Jigsaw (98dB) rather than a Circular saw (110 dB). Under no circumstances will a generator operating above 60dB be used (Normal Conversation 60-65 dB).

5. Planning: Each task will make the maximum use of pre-planning to reduce the need for power tools within the Wilderness. For example; To the maximum extent possible, material will be pre-cut prior to entering the Wilderness.

1.12 SPECIAL CONSTRUCTION REQUIREMENTS

A. Project Website: A project website administered by NPS will be used for purposes of managing communication and documents during construction stage.

1. See Section 01 31 00 "Project Management and Coordination" for requirements on using Project Website.

1.13 SOILS INVESTIGATION REPORT

A. The report of Geotechnical Exploration – Congaree National Park – Additional Boardwalk Replacement prepared by S&ME is an appendix with this package.

B. In case of conflict between report and drawings or specifications, the drawings and specifications govern.

1.14 ADDITIONAL REPORTS

A. The existing survey data prepared by Parker Land Surveying, LLC is included in the Drawings.

B. Existing boardwalk hazmat sampling as an appendix to these specifications (Future report to be provided). Sampling & Report done by S&ME, 9/27/2023
