1.2 WORK COVERED BY CONTRACT DOCUMENTS

A. Project Location: Little Bighorn Battlefield National Monument, Montana Replace Existing

Dilapidated Visitor Center Facility.

B. The Work consists of:

Little Bighorn Battlefield National Monument (LIBI) is located in central Montana and tells an important story that is best illustrated by the mission of the Park: To preserve and protect the historic and natural resources pertaining to the Battle of the Little Bighorn and to provide visitors with a greater understanding of those events which lead up to the battle, the encounter itself, and the various effects the encounter had on the two cultures involved.

Little Bighorn Battlefield National Monument has approximately 300,000 visits annually. A minimum of 75% of the visitors obtain information and participate in the interpretive talks and exhibits at the Visitor Center. Opened in 1952, the Visitor Center was designed to accommodate

100,000 annual visitors. It does not have a theater room, and it is too small to facilitate visitor flow, provide information and an adequate interpretive experience. The lobby, bookstore and museum area are inadequately sized, as confirmed by space analysis through the Facility Planning

Model. Space limitations have forced the park to move interpretive talks to an exterior patio, which exposes visitors to extreme temperatures and thunderstorms, which can cause cancelling of programs. Current facilities cannot accommodate thousands of visitors per year. The park film is shown in a small room (440 sq feet) that can only safely accommodate 30 visitors at a time.

Ranger led programs are conducted on an open-air patio whose design can only safely accommodate 200 visitors at a time. The building has significant safety and building code issues.

Pest infestations occur throughout the building. Water intrusion has damaged rooms on both

LIBI 241430 01 11 00 - 2

floors. The fire detection and intrusion alarm systems are outdated and not code compliant. The building does not have a fire suppression system. Neither the exterior nor interior stairways meet code requirements. The basement does not meet accessibility standards and contains the only employee restroom and breakroom in the building. Doorways throughout the building do not meet standards for accessible design including clearance requirements, width standards or opening force or closing speed standards. The HVAC system is beyond its useful life and overtaxed; it cannot provide sufficient, equalized climate-control for visitors and exhibits. The existing building has had several additions and been reconfigured many times since it was originally built.

The HVAC system cannot accommodate the new configurations resulting in hot and cold areas, which make visitor and employee areas uncomfortable and results in excessive energy use.

This project includes the demolition of the existing visitor center and associated site improvements. It also includes the construction of a new visitor center and associated site improvements, including but not limited to:

• New two-level visitor center building with roof top access.

• New site improvements for visitor plazas, pedestrian walkways, landscaping and irriga-tion.

• Improvements to a portion of the existing parking area for universal accessibility.

• The Government will provide the temporary double-wide trailer with accessible ramp and stairs for temporary visitor center functions during demolition of the existing and construction of the new visitor center. Location for the temporary visitor center has been provided on the construction documents for reference only.

• There will be a separate contract for the fabrication and installation of exhibits into the new visitor center.

This project shall meet Federal sustainability requirements but will not be required to be USGBC

LEED certified.

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

1.3 WORK PHASES

A. The Work shall be conducted in one single phase with demolition of the existing visitor center taking place prior to the construction of the new visitor center. The new visitor center will essentially be constructed within the footprint of the existing visitor center to minimize ground disturbance.

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.

Federal Highways-Roadway and parking improvements: There will be a separate project by

Federal Highways to renovate/improve the existing Visitor Center Roadway and parking area.

Construction will occur during the middle to end of the Visitor Center construction. The Visitor

Center General Contractor will be required to coordinate use of the existing parking area with the

Federal Highways project.

LIBI 241430 01 11 00 - 3

The Visitor Center Contractor will need to vacate the parking lot staging area by August 1, 2025.

After this date, the Visitor Center Contractor will not have access to the parking lot as a staging area for the duration of the project, due to the Federal Highways Project (separate contract) to resurface the road and re-grade/resurface the parking area. The Visitor Center Contractor can use the parking lot for deliveries, but not for staging, during this phase of the project.

The Government will be providing the Temporary Visitor Center Trailer(s) and associated power.

B. Future Work: Government will award separate contract(s) for the following additional work to be performed at site after Substantial Completion. Completion of that work will depend on successful completion of preparatory work under this Contract.

1. Exhibit fabrication and installation: Work for this contract will commence at the completion of the construction of the new Visitor Center.
