PART 1 – GENERAL

ITEM 1 – DESCRIPTION OF WORK

1.1 Background:

The log cabins located at Price Park B545, Crabtree Falls B832, and Mt. Pisgah Campgrounds B828 on the Blue Ridge Parkway have experienced progressive weathering, deteriorated chinking, and fading of protective wood stain due to prolonged environmental exposure. These cabins are vital assets to the housing program at BLRI and are a huge asset to being able to hire seasonal employees that care for our campgrounds and thousands of visitors. This project aims to restore the cabins' weather resistance and aesthetics through the complete removal and replacement of failed chinking and the application of an approved semi-transparent stain to all log and siding surfaces.

1.2 Work Covered by the Contract Documents:

The contractor shall provide all labor, materials, equipment, and supervision to perform the following work under a single lump-sum contract:

· Stain window and door trim at each cabin (each cabin has 4 windows and 2 doors, total: 12 windows and 6 doors). This work shall include surface cleaning, masking, application of exterior-grade primer as needed, and two coats of park-approved low-VOC trim paint. Execution details are provided under Phase 3 – Staining.

· Cabin 1 – Price Park Campground B545:

· Remove deteriorated chinking and install new synthetic chinking: 622 linear feet

· Power wash, prep, and stain logs/siding: 1,010 square feet

· Cabin 2 – Crabtree Falls Campground B832:

· Remove deteriorated chinking and install new synthetic chinking: 545 linear feet

· Power wash, prep, and stain logs/siding: 1,005 square feet

· Cabin 3 – Mt. Pisgah Campground B828:

· Remove deteriorated chinking and install new synthetic chinking: 627 linear feet

· Power wash, prep, and stain logs/siding: 1,017 square feet Work shall comply with National Park Service conservation standards and Secretary of the Interior’s Standards for Rehabilitation. Chinking shall be a compatible synthetic system (e.g., Sashco Log Jam or approved equal) matching original appearance and texture. Stain shall be breathable, low-VOC, semi-transparent log stain (e.g., Perma-Chink Ultra-2 or equivalent) in a park-approved color.

Period of Performance:

All work shall be completed within 120 calendar days from time of award.

ITEM 2 – EXISTING UTILITIES

2.1 Contractor shall contact the Contracting Officer and local utility authorities for utility locating services before any anchoring or drilling activities.

2.2 The contractor is responsible for the protection of all known and discovered utilities. All damages shall be reported and repaired at no cost to the Government.

2.3 Water and power will be provided by the park at each cabin site. Contractor shall coordinate with the COR during the preconstruction conference for utility access logistics and connection points.

ITEM 3 – CONTRACTOR’S USE OF PREMISES

3.1 Project access shall be confined to designated parking and driveway areas. Do not disturb adjacent vegetation or trails.

3.2 Working hours are Monday–Friday, 8:00 a.m.–4:30 p.m. Work on weekends or holidays will not be permitted.

3.3 Storage and staging are limited to pre-approved laydown areas adjacent to each cabin. Protect all resources, trees, and surfaces during performance.

ITEM 4 – COMMENCEMENT, PROSECUTION, AND COMPLETION

4.1 Contractor must submit a critical path schedule with milestones for mobilization, chinking removal, surface prep, chinking install, staining, and final inspection.

4.2 Work shall commence once contract is award.

ITEM 5 – EXAMINATION OF THE SITE
