TABLE OF CONTENTS

GENERAL

DESCRIPTION

A. Contract Line Item No. 1 (BASE BID): BLDG 722 - This item shall consist of: Configuration and installation of a hydraulically designed NFPA 13 automatic dry pipe sprinkler system. The work includes buried and concealed distribution piping, insulated above-ground distribution piping, sprinklers and other related components and appurtenances for complete coverage of Building 722. System will connect to existing fire line stub located outside the building. The system shall be designed and constructed in accordance with National Park Service Reference Manual #58 (Structural Fire Management) and this scope of work.

Ground disturbance is limited to the area from the existing fire line stub to the limits of the building crawl space. Ground disturbance must not exceed the depth of the existing approximate 2-3 feet of fill. Ground disturbance is not allowed in the crawl space under the building, and therefore piping in this area must be insulated and above-ground.

The Composite Utility Plan (Attachment 1) illustrates the location (southeast corner) of the existing underground fire line stub serving this building. This underground water line will be extended below grade within fill to the limits of the building crawlspace, at which point the piping shall be above-ground to provide a connection to the proposed riser location in the mechanical room. The system will provide a completely functional system to protect all required areas. The contractor will connect the fire suppression system to the existing fire alarm system (location shown in Attachment 2).

The building floor area covers approximately 2,030 square feet. Attachment 2 contains floor plans which illustrates the current configuration of this one-story stick-built structure.

B. Contract Line Item No. 2 (BASE BID): BLDG 704 - This item shall consist of: Configuration and installation of a hydraulically designed NFPA 13 automatic dry pipe sprinkler system. The work includes buried and concealed distribution piping, sprinklers, and other related components and appurtenances for complete coverage of Building 704. The system shall be designed and constructed in accordance with National Park Service Reference Manual #58 (Structural Fire Management) and this scope of work.

The Composite Utility Plan (Attachment 1) illustrate the location (northeast corner) of the existing underground fire line stub serving this building. This underground water line will be extended below grade to provide a connection to the proposed riser location in the mechanical room and will provide a completely functional system to protect all required areas. The contractor will connect the fire suppression system to the existing fire alarm system (location shown in Attachment 2).

The building floor area covers approximately 1,310 square feet. Attachment 2 contains floor plans which illustrates the current configuration of this one-story stick-built structure.

C. BID OPTION A: BLDG 733 - This item shall consist of: Configuration and installation of a hydraulically designed NFPA 13 automatic dry pipe sprinkler system. The work includes buried and concealed distribution piping, insulated above-ground distribution piping, sprinklers and other related components and appurtenances for complete coverage of Building 733. The system shall be designed and constructed in accordance with National Park Service Reference Manual #58 (Structural Fire Management), and this scope of work.

The Composite Utility Plan (Attachment 1) illustrate the location (northwest corner) of the existing underground fire line stub serving this building. This underground water line will be extended below grade to the building footprint and continued below or above grade to provide a connection to the proposed riser location in the basement furnace room and will provide a completely functional system to protect all required areas. The contractor will connect the fire suppression system to the existing fire alarm system (location shown in Attachment 2).

The building floor area covers approximately 2,550 square feet. Attachment 2 contains floor plans which illustrates the current configuration of this one-story stick-built structure.

D. BID OPTION B: BLDG 721 - This item shall consist of: Configuration and installation of a hydraulically designed NFPA 13 automatic dry pipe sprinkler system. The work includes concealed distribution piping, sprinklers and other related components and appurtenances for complete coverage of Building 721. The system shall be designed and constructed in accordance with National Park Service Reference Manual #58 (Structural Fire Management) and this scope of work.

The Composite Utility Plan (Attachment 1) illustrates the location (southeast corner) of the existing service connection located in the mechanical room. The fire suppression system will connect at this location and will provide a completely functional system to protect all required areas. The contractor will connect the fire suppression system to the existing fire alarm system (location shown in Attachment 2).

This building consists of three (3) levels or floors. The basement and 1st floor cover approximately 5,150 square feet each while the Mezzanine level covers approximately 730 square feet (approximately 11,030 square feet total). The first floor contains a large, double-height space covering approximately 3,600 square feet

The large open spaces at the basement and 1st floor levels have pressed tin ceilings, and the 1st floor has maple floorboards. The tin ceilings and maple floorboards are significant historic features. Attachment 2 contains floor plans which illustrates the current configuration of this structure.

Building 721 could potentially remain unoccupied in the future, and therefore the fire sprinkler distribution piping does not need to be concealed at this time. The design of the sprinkler system for Building 721 should accommodate for future changes to the floorplan.

All work will be performed under a single contract.

ARCHEOLOGICAL PROTECTION

E. All buildings are within a highly archeologically sensitive area. The area may contain historically significant buried features, artifacts, or human remains. The Contractor shall strictly limit and control the depth and/or extent of excavations, minimizing them to the greatest extent possible.

F. All ground disturbance must be monitored by a professional archaeologist. Refer to section 1.17-C, 2.02, and 3.04 - 3.06.
