PART 3 - EXECUTION

3.1EXAMINATION

  1. Inspect surfaces, backing, and structural systems to receive metal framing, furring and ceiling suspension systems, and report any discrepancies in writing to Project Manager for resolution. Starting work implies acceptance of existing conditions.

3.2PREPARATION

  1. Obtain dimensions and locations from other trades, and provide openings and enclosures for accessories, specialties, equipment and ductwork.

3.3INSTALLATION

  1. General:
  2. Erect metal framing, shaftwall framing, and ceiling suspension systems in accordance with ASTM 754, CBC and Division 01 Section "Lateral Force Procedures", and manufacturer's recommendations.
  3. Attach securely to building structure. Include all welding required for attachment of clips and attachment devices to structural steel frame.
  4. Install members true to lines and levels to provide flatness with maximum variation of 1/8 inch (3 mm) in 10 feet (3 m) in any direction for walls, and 1/8 inch (3 mm) in12 feet (3.6 m) for ceilings.
  5. Install backing plates at studs to support wall mounted items, including fixtures, lavatories, counters, shelves, casework, accessories, and hardware. Weld to studs 16 gauge and heavier, screw to studs 18 gauge and lighter.
  6. Coordinate installation of bucks, anchors, blocking, electrical and mechanical work which is to be placed in or behind partition or ceiling framing. Allow items to be installed after framing is complete.
  7. Safing Insulation: Comply with Division 07 Section "Penetration Firestopping".
  8. Metal Framing:
  9. Door Opening Framing: Install double studs at door frame jambs. Install runners on each side at frame head height between jamb studs and adjacent studs.
  10. Install solid blocking at edges of gypsum board panels.
  11. Furring: Install wall furring channels vertically, unless otherwise indicated. [Unless otherwise indicated, terminate vertical furring 3 inches (75 mm) above suspended ceilings.]

<Edit the following paragraph as appropriate.>

  1. Ceiling Framing:
  2. Coordinate location of hangers with other work. Provide trapeze supports and steel bracing as required to support ceiling.
  3. Install ceiling framing independent of walls, columns, and above-ceiling work.
  4. Space main carrying at maximum 48 inches (1219 mm) on center, maximum 6 inches (150 mm) from boundary walls or interruptions in ceiling continuity. Lap splices minimum 12 inches (300 mm) and secure together 2 inches (50 mm) from each end of splice. Level channels to provide a tolerance of 1/8 inch (3 mm) in 12 feet (3.6 m) in finished ceiling.
  5. Place metal furring channels perpendicular to carrying channels. Space furring channels at maximum 24 inches (600 mm) on center. Lap splices minimum 8 inches 200 mm) and secure together 2 inches (50 mm) from each end of splice.
  6. Reinforce openings which interrupt channels, with lateral channel bracing extending minimum 24 (600 mm) past each end of openings.
  7. Laterally brace entire suspension system.

<Include the following paragraph if appropriate.>

3.4WASTE MANAGEMENT
