Use hand tools or small power tools designed for sawing or grinding, not hammering and chopping. Temporarily cover openings to remain.

2. Cut or drill from the exposed or finished side into concealed surfaces to avoid marring existing finished surfaces.

3. Do not use cutting torches until work area is cleared of flammable materials. At concealed spaces, such as duct and pipe interiors, verify condition and contents of hidden space before starting flame-cutting operations. Maintain portable fire-suppression devices during flame-cutting operations.

4. Maintain fire watch during and for at least two (2) hours after flame-cutting operations.

5. Locate selective demolition equipment and remove debris and materials so as not to impose excessive loads on supporting walls, floors, or framing.

6. Dispose of demolished items and materials promptly. Demolished items and wastes shall be promptly containerized in manner to prevent materials from becoming airborne and spreading by wind.

3.5 CLEANING

A. Remove demolition waste materials from Project site and recycle or dispose of them according to Section 010150.

1. Do not allow demolished materials to accumulate on-site.

2. Do not allow demolished materials to become airborne and spread across project site, or onto other parts of Airport, or otherwise interfere with operations of Government and adjacent facilities.

3. Remove and transport debris in a manner that will prevent spillage on adjacent surfaces and areas.

B. Burning: Do not burn demolished materials.

C. Clean adjacent structures and improvements of dust, dirt, and debris caused by selective demolition operations. Return adjacent areas to condition existing before selective demolition operations began.
