done by workmen skilled in this type of work. All patching shall be done utilizing materials of the same quality and texture as the adjacent undisturbed areas perfectly and to the satisfaction of the Engineer. a. Cutting: Cut and remove existing construction only to the extent required by new Work and as indicated. Use methods required to complete Work within limitations of governing regulations and as follows: 1) Neatly cut openings and holes plumb, square, and true to dimensions required. Use cutting methods least likely to damage construction to remain or adjoining construction. To minimize disturbance of adjacent surfaces, use hand 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 adequate ventilation when using cutting torches. 5) Cut concrete and masonry at junctures with construction to remain, using power driven masonry saw or hand tools; do not use power driven impact tools. b. Patching: Return elements of construction and surfaces to remain to condition existing before start of cutting operations. c. Painting 1) Painting of the final finished areas will be by the Prime Contractor. If no Prime Contractor is assigned to this project, the E.C. will provide touch up painting to architectural finishes. 2) Where cutting and patching occurs in areas that the General Contractor does not have any work and/or the General Contractor is not required to finish the wall and/or ceiling that was affected by this Contractor’s work, the Electrical Contractor shall paint the affected surface from “natural” break to “natural“ break as directed by the Engineer. When other trades other than the General Contractor damage the same wall and/or ceiling, the Electrical Contractor shall coordinate his painting responsibilities with the other trades before proceeding with any work in that area. 3) All surfaces to be painted shall receive an undercoat 24 hours before the final coat is applied. Undercoats which show lumps or rough areas shall be smoothed with fine sandpaper or steel wool and dusted of before the final coat is applied. Final coat shall be solid, even color, free of lumps, drops, sags, run brush marks, laps, or other defects, finished to a line where they adjoin other colors or unpainted surfaces. 4) Drop cloths shall be used to protect floors and all other work from damage. Any covering temporarily removed from any part of the work or finish shall be promptly replaced and any damage from neglect to protect all surfaces shall be at the Contractor’s expense.
