SUMMARY OF WORK

PART 1 - GENERAL

1.1 SUMMARY

This project includes all work specified in the following specifications and drawings to reconstruct the Chief Shakes Hot Springs building. Major work includes foundation repair to decaying cedar posts and replacement of roofs on hot tub structure. Remove decaying portion of cedar posts and replace with concrete column. Reinforce cedar posts with metal bands. Remove and replace roof components: tongue and groove decking, underlayment, shakes, and flashing.

Government will furnish materials listed on drawing sheet 2 notes. Contractor will furnish all labor, additional material, additional equipment, supervision, and transportation necessary to complete the required work. Work to be completed in accordance with drawings, specifications, and provisions of the contract.

Remove and appropriately dispose any trash generated from work. Excess government furnished material remaining after work to be returned to government.

This project is located at the Chief Shakes Hot Springs day use facility approximately 25 miles north-east of Wrangell, Alaska. The site is typically accessed by boat. The ease of access depends heavily on the water height of the Stikine River. The higher the river level the easier the access, typically for hauling construction materials a river height of

19’ is required to get materials directly to the site’s access trail. The length of the trail is

950’ from the low water stairs and 450’ from the high water dock. The river height is usually highest from mid-May to mid-July.

1.2 USE OF PREMISES

A. Contractor shall at all times conduct operations to ensure the least inconvenience to the public.
