THE CITY OF SUNNY ISLES BEACH <br />PROJECT NO. 21-1011 <br />BUILDING DEPARTMENT RELOCATION TO ANNEX <br /> <br />Project No. 21-1011 November 2024 024119 Selective Demolition-4 <br /> <br />A. Demolish and remove existing construction only to the extent required by new construction <br />and as indicated. Use methods required to complete the Work within limitations of <br />governing regulations and as follows: <br /> <br />1. Proceed with selective demolition systematically, from higher to lower level. <br />Complete selective demolition operations above each floor or tier before disturbing <br />supporting members on the next lower level. <br /> <br />2. Cut openings and holes plumb, square, and true to dimensions required. Use <br />cutting methods least likely to damage construction to remain or adjoining <br />construction. Use hand tools or small power tools designed for sawing or grinding, <br />not hammering and chopping, to minimize disturbance of adjacent surfaces. <br />Temporarily cover openings to remain. <br /> <br />3. Cut or drill from the exposed or finished side into concealed surfaces to avoid <br />marring existing finished surfaces. <br /> <br />4. Do not use cutting torches until work area is cleared of flammable materials. At <br />concealed spaces, such as duct and pipe interiors, verify condition and contents of <br />hidden space before starting flame-cutting operations. Maintain fire watch and <br />portable fire-suppression devices during flame-cutting operations. <br /> <br />5. Maintain adequate ventilation when using cutting torches. <br /> <br />6. Remove decayed, vermin-infested, or otherwise dangerous or unsuitable materials <br />and promptly dispose of off-site. <br /> <br />7. Remove structural framing members and lower to ground by method suitable to <br />avoid free fall and to prevent ground impact or dust generation. <br /> <br />8. Locate selective demolition equipment and remove debris and materials so as not <br />to impose excessive loads on supporting walls, floors, or framing. <br /> <br />9. Demolish concrete and masonry in small sections. Cut concrete and masonry at <br />junctures with construction to remain using power-driven masonry saw or hand <br />tools; do not use power-driven impact tools. <br /> <br />10. Provide services for effective air and water pollution controls as required by local <br />authorities having jurisdiction. <br /> <br />11. Demolish foundation walls to a depth of not less than 12 inches below existing <br />ground surface. <br /> <br />12. Break up below-grade concrete slabs. <br /> <br />13. For interior slabs on grade, use removal methods that will not crack or structurally <br />disturb adjacent slabs or partitions. Use power saw where possible. <br /> <br />14. Completely fill below-grade areas and voids resulting from demolition work. <br />Provide fill consisting of approved earth, gravel, or sand, free of trash and debris,
