Use methods required to complete the Work within limitations of <br />governing regulations and as follows: <br />1.Proceed with selective demolition systematically, from higher to lower level. Complete <br />selective demolition operations above each floor or tier before disturbing supporting <br />members on the next lower level. <br />2.Neatly cut openings and holes plumb, square, and true to dimensions required. Use cutting <br />methods least likely to damage construction to remain or adjoining construction. Use hand <br />tools or small power tools designed for sawing or grinding, not hammering and chopping. <br />Temporarily cover openings to remain. <br />3.Cut or drill from the exposed or finished side into concealed surfaces to avoid marring <br />existing finished surfaces. <br />4.Do not use cutting torches until work area is cleared of flammable materials. At concealed <br />spaces, such as duct and pipe interiors, verify condition and contents of hidden space <br />before starting flame-cutting operations. Maintain portable fire-suppression devices during <br />flame-cutting operations. <br />5.Maintain fire watch during and for at least two hours after flame-cutting operations. <br />6.Maintain adequate ventilation when using cutting torches. <br />7.Remove decayed, vermin-infested, or otherwise dangerous or unsuitable materials and <br />promptly dispose of off-site. <br />8.Remove structural framing members and lower to ground by method suitable to avoid free <br />fall and to prevent ground impact or dust generation. <br />9.Locate selective demolition equipment and remove debris and materials so as not to impose <br />excessive loads on supporting walls, floors, or framing. <br />10.Dispose of demolished items and materials promptly. Comply with requirements in <br />Section 01 7419 "Construction Waste Management and Disposal." <br />B.Site Access and Temporary Controls: Conduct selective demolition and debris-removal operations <br />to ensure minimum interference with roads, streets, walks, walkways, and other adjacent occupied <br />and used facilities. <br />C.Existing Items to Remain: Protect construction indicated to remain against damage and soiling <br />during selective demolition. When permitted by Architect, items may be removed to a suitable, <br />protected storage location during selective demolition and cleaned and reinstalled in their original <br />locations after selective demolition operations are complete. <br />3.5 SELECTIVE DEMOLITION PROCEDURES FOR SPECIFIC MATERIALS <br />A.Concrete: Demolish in sections. Cut concrete full depth at junctures with construction to remain <br />and at regular intervals using power-driven saw, and then remove concrete between saw cuts.
