The project involves the removal of the current dry pipe, water-based fire suppression system, and installing new automatic dry pipe systems and associated components to ensure a fully functional fire suppression system that provides comprehensive coverage for Apartment Buildings 94 and 96. These systems must be designed and installed in compliance with all relevant codes and standards specified in this scope of work and National Park Service (NPS) Standards.

1.2 LOCATION

A. The project is located in the West Glacier Headquarters area of Glacier National Park.

1.3 SPECIAL PROCEDURES

A. All work, including but not limited to architectural, mechanical, electrical, and structural, shall be performed with extreme care to avoid damage to existing materials that remain or that need to be removed and reinstalled.

Where "hot work" (open flame, grinding, welding, brazing, smelting) is required, the Contractor shall apply for and have on-site, at all times, a valid National Park Service hot work permit.

B. The authority having jurisdiction (AHJ) is the National Park Service Intermountain Region Structural Fire Management Officer.

1.4 MINIMAL DAMAGE

A. This project intends to maintain the historic and non-historic finishes and materials with "minimal damage" due to the work. Minimal damage is defined as removal and replacement with the same removed material without discernible damage to the material or no more than one small hole that is less than two (2) inch square in any one-foot square area. Damaged materials shall be replaced with similar or in-kind materials as the Contractor Officer approves.

B. Where required, the Contractor shall provide temporary service for utilities that are disrupted by work. The Contractor shall coordinate all temporary service disruptions with the NPS and other on-site contractors. The Contractor shall notify the Contracting Officer 48 hours before any planned utility interruptions.

C. Piping offsets, fittings, and any other accessories required shall be furnished to provide a complete installation and eliminate interference with other construction. Sprinklers shall be installed over and under ducts, piping, and platforms when such equipment negatively affects or disrupts the sprinkler discharge pattern and coverage.
