Where no conduit or wire size is shown, install 1/2" conduit with two 412 <br />AWG wires. <br />C. Make installation in strict accordance with branch circuit numbering as <br />shown. <br />3.04 CUTTING, FORMING, PATCHING <br />A. Concrete and Masonry Construction: <br />1. Provisions will be made under General Work for all openings, recesses, <br />chases, etc, and wood blocking required for Electrical Work. Notify <br />General Contractor in ample time, when and where such provisions are <br />necessary. <br />2. Install equipment in concrete slab, beam, or other location where struc- <br />tural value of construction may be affected, as directed and approved by <br />State. Move or alter any electrical equipment required to be moved or <br />altered due to structural conditions at no additional cost to State. <br />3. Furnish and install all conduit sleeves, inserts, and supports for <br />electrical work, unless otherwise specified or shown. <br />4. Install pipe sleeves through full thickness of concrete and provide 1/2" <br />min clearance around conduit. <br />5. Sleeves 2" dia and smaller, 30 ga steel. Sleeves 2-1/2" dia and larger, <br />26 ga steel. Approved plastic sleeves may be used in lieu of steel sleeves. <br />6. Remove sleeves after concrete forms have been removed. Caulk space around <br />conduit through openings above grade, if the opening is through an exte- <br />rior wall, or if airtight separation is required by Mechanical Work, or <br />if directed by State. <br />7. Where conduit will be installed after concrete slab is poured and con- <br />struction requires watertight membrane, furnish and install permanently <br />anchored standard weight galvanized steel pipe sleeves extending 2" <br />above finish floor and having 1/2" min clearance around conduit. Do not <br />remove these sleeves. Caulk space betwen conduit and sleeve with oakum <br />and mastic, and make watertight. <br />B. Steel Construction: Do not weld or burn any structural steel member. <br />Obtain specific approval of State before field welding or burning not <br />called for on contract or approved shop drawings. Do not burn holes in beam <br />flanges or narrow members. <br />C. Wood Construction: <br />1. Bore or cut holes in structural members for conduit and cables neatly and <br />as small as possible. <br />2. Boring and cutting of wood girders, beams, or joists is limited to a <br />location within 3 times beam depth from either support, and not exceeding <br />1/5 of beam depth from top of beam. <br />3. In stud walls, place conduits or cables in center of plates or studs using <br />neat holes. Notching is not permitted. <br />021387:cw MAR 702 <br />
