DIVISION 1 SHORT FORM GENERAL REQUIREMENTS

PART 1 – GENERAL

ITEM 1 - DESCRIPTION OF WORK

1.1 Background: The Interpretive (informational and educational use) shelter at Knife River Indian Villages National Historic Site consists of a 2003 pre-fabricated glu-laminated arch beamed open wood structure with a custom fabricated enclosure at one end. The enclosure is used by NPS for storage of materials which are utilized in the interpretive programs presented to the public. The enclosure is currently 2x4 wood framing with OSB sheathing and stained wood tongue-and-groove siding. The roof of the shelter is asphalt shingles. Improvements to the exterior finish materials are needed due to weathering and aging of material as well as upgrades to existing electrical service sourced from the adjacent Visitors Center in order to serve the continued needs of the park, both in sustaining the structure and providing interpretive programs to visitors.

Improvements to the project are to include
