| c. | Furring for pipes and duct shafts. |
| B. | In locations other than those specified, extend gypsum board from floor to heights as follows: |
| 1. | Not less than 100 mm (4 inches) above suspended acoustical ceilings. |
| 2. | At ceiling of suspended gypsum board ceilings. |
| 3. | At existing ceilings. |
3.2 INSTALLING GYPSUM BOARD
| A. | Coordinate installation of gypsum board with other trades and related work. |
| B. | Install gypsum board in accordance with ASTM C840, except as otherwise specified. |
| C. | Use gypsum boards in maximum practical lengths to minimize number of end joints. |
| D. | Bring gypsum board into contact, but do not force into place. |
| E. | Ceilings: |
| 1. | For single-ply construction, use perpendicular application. |
| 2. | For two-ply assembles: |
| a. | Use perpendicular application. |
| b. | Apply face ply of gypsum board so that joints of face ply do not occur at joints of base ply with joints over framing members. |
| F. | Walls: |
| 1. | When gypsum board is installed parallel to framing members, space fasteners 300 mm (12 inches) on center in field of the board, and 200 mm (8 inches) on center along edges. |
| 2. | When gypsum board is installed perpendicular to framing members, space fasteners 300 mm (12 inches) on center in field and along edges. |
| 3. | Stagger screws on abutting edges or ends. |
| 4. | For single-ply construction, apply gypsum board with long dimension either parallel or perpendicular to framing members as required to minimize number of joints except gypsum board shall be applied vertically over "Z" furring channels. |
| 5. | For two-ply gypsum board assemblies, apply base ply of gypsum board to assure minimum number of joints in face layer. Apply face ply of wallboard to base ply so that joints of face ply do not occur at joints of base ply with joints over framing members. |
| 6. | No offset in exposed face of walls and partitions will be permitted because of single-ply and two-ply or three-ply application requirements. |

| b. | Where gypsum board terminates against dissimilar materials and at perimeter of openings, except where covered by flanges, casings or permanently built-in equipment. |
| c. | Where gypsum board surfaces of non-load bearing assemblies abut load bearing members. |
| d. | Where shown. |
3.3 FINISHING OF GYPSUM BOARD
| A. | Finish joints, edges, corners, and fastener heads in accordance with ASTM C840. Use Level 4 finish for al finished areas open to public view. |
| B. | Before proceeding with installation of finishing materials, assure the following: |
| 1. | Gypsum board is fastened and held close to framing or furring. |
| 2. | Fastening heads in gypsum board are slightly below surface in dimple formed by driving tool. |
| C. | Finish joints, fasteners, and all openings, including openings around penetrations, on that part of the gypsum board extending above suspended ceilings to seal surface of non decorated smoke barrier, fire rated, and sound rated gypsum board construction. After the installation of hanger rods, hanger wires, supports, equipment, conduits, piping and similar work, seal remaining openings and maintain the integrity of the smoke barrier, fire ratedand sound rated construction. Sanding is not required of non decorated surfaces. |
3.4 REPAIRS
| A. | After taping and finishing has been completed, and before decoration, repair all damaged and defective work, including non decorated surfaces. |
| B. | Patch holes or openings 13 mm (1/2 inch) or less in diameter, or equivalent size, with a setting type finishing compound or patching plaster. |
| C. | Repair holes or openings over 13 mm (1/2 inch) diameter, or equivalent size, with 16 mm (5/8 inch) thick gypsum board secured in such a manner as to provide solid substrate equivalent to undamaged surface. |
| D. | Tape and refinish scratched, abraded or damaged finish surfaces including cracks and joints in non-decorated surface to provide smoke tight construction fire protection equivalent to the fire rated construction, and STC equivalent to the sound rated construction. |
