Selective Structure Demolition 17678 02 4119/2 of 4

D. Hazardous Materials: It is not expected that hazardous materials will be encountered in the work.

1. If materials suspected of containing hazardous materials are encountered, do not disturb; immediately notify the Architect and Owner. Owner will remove hazardous materials under a separate contract.

E. Storage or sale of removed items or materials on site is not permitted.

F. Utility Service: Maintain existing utilities indicated to remain in service and protect them against damage during selective demolition operations.

PART 3 – EXECUTION

3.1 EXAMINATION

A. Verify that utilities have been disconnected and capped.

B. Survey existing conditions and correlate with requirements indicated to determine extent of selective demolition required.

C. Inventory and record the condition of items to be removed and reinstalled and items to be removed and salvaged. See Architectural drawings for process by which items can be removed from the site.
