Do not close or obstruct streets, walks, or other adjacent occupied or used facilities without permission from <br /> Owner and authorities having jurisdiction. Provide alternate routes around closed or obstructed traffic ways if <br /> required by governing regulations. <br /> C. Provide and maintain interior and exterior shoring, bracing, or structural support to preserve stability and prevent <br /> movement, settlement, or collapse of building to be selectively demolished. <br /> 1. Strengthen or add new supports when required during progress of selective demolition. <br /> 3.4 POLLUTION CONTROLS <br /> A. Use water mist, temporary enclosures, and other suitable methods to limit the spread of dust and dirt. Comply with <br /> governing environmental protection regulations. <br /> 1. Do not use water when it may damage existing construction or create hazardous or objectionable conditions, <br /> such as ice,flooding, and pollution. <br /> B. Remove and transport debris in a manner that will prevent spillage on adjacent surfaces and areas. <br /> 1. Remove debris from elevated portions of building by chute, hoist,or other device that will convey debris to grade <br /> level. <br /> C. Clean adjacent structures and improvements of dust, dirt, and debris caused by selective demolition operations. <br /> Return adjacent areas to condition existing before start of selective demolition. <br /> 3.5 SELECTIVE DEMOLITION <br /> A. Demolish and remove existing construction only to the extent required by new construction and as indicated. Use <br /> methods required to complete Work within limitations of governing regulations and as follows: <br /> 1. Proceed with selective demolition systematically,from higher to lower level. Complete selective demolition work <br /> above each floor or tier before disturbing supporting members on lower levels. <br /> 2. Neatly cut openings and holes plumb, square, and true to dimensions required. Use cutting methods least likely <br /> to damage construction to remain or adjoining construction. To minimize disturbance of adjacent surfaces, use <br /> hand or small power tools designed for sawing or grinding, not hammering and chopping. Temporarily cover <br /> openings to remain. <br /> 3. Cut or drill from the exposed or finished side into concealed surfaces to avoid marring existing finished surfaces. <br /> 4. Do not use cutting torches until work area is cleared of flammable materials.At concealed spaces, such as duct <br /> and pipe interiors, verify condition and contents of hidden space before starting flame-cutting operations. <br /> Maintain portable fire-suppression devices during flame-cutting operations. <br /> 5.

Dispose of demolished items and materials promptly. On-site storage or sale of removed items is prohibited. <br /> 10. Return elements of construction and surfaces to remain to condition existing before start of selective demolition <br /> operations. <br /> 3.6 PATCHING AND REPAIRS <br /> A. Promptly patch and repair holes and damaged surfaces caused to adjacent construction by selective demolition <br /> operations. <br /> B. Patching is specified in Division 01, Section "Cutting and Patching." <br /> C. Restore exposed finishes of patched areas and extend finish restoration into adjoining construction to remain in a <br /> manner that eliminates evidence of patching and refinishing. <br /> D. Patch and repair floor and wall surfaces in the new space where demolished walls or partitions extend one finished <br /> area into another. Provide a flush and even surface of uniform color and appearance. <br /> E. Patch, repair, or rehang existing ceilings as necessary to provide an even-plane surface of uniform appearance. <br /> 3.7 DISPOSAL OF DEMOLISHED MATERIALS <br /> A.
