PART 1 – SUMMARY OF WORK (SECTION 01 11 00)

1.1 WORK COVERED BY CONTRACT DOCUMENTS

A. General: All work outlined below will be performed under a single contract.

B. Project Location: This project is located at Oregon Caves National Monument, at the Chalet building.

C. Project Background: The Chalet at Oregon Caves National Monument is a historic wooden structure.
