8.0 CONSTRUCTION METHODS AND TECHNOLOGY

8.1 Plasterboard Ceiling

Once completed, the coordinator shall inform the subcontractor on the request for an inspection by coordinator and clerk of work approval prior to commencing of any physical works.
• Then installation of the ceiling brackets and hanger rods. Upon completion of the droppers and hangers, then proceed to install the adjustable suspension brackets prior to installing the main top cross rail and TCR to FCR connector and lastly the furring channels.

• Once all ceiling are completed, the subcontractor shall request that the trades commence all marking and setting out works so as to enable all opening or penetration be made prior to plastering works.






8.2 Suspended Aluminium Clip in Plank Ceiling

• Clip in section installation should follow strictly to the shop drawing as approved.
• Confirm the ceiling finish marking and fix wall angle to perimeter wall at the correct height and check for level.
• Fix suspension wire with suspension brackets attached, to approximated height at 1000mm (recommended from the manufacturer) maximum centre in both directions.
• Tight up the primary clip in section with suspension wire, adjust height of primary clip in section to a line stretched between wall angles and ensuring the fitting correctly tightness.
• Install the secondary clip in section 1200mm centre and check all fitting for tightness and safety.
• After suspension components are installed, all the M&E opening marking as per drawing, the subcontractor will provide the ceiling panels / plank as required for M&E trade to do the opening and installation by M&E respective contractor.
• The Subcontractor will complete up the remaining ceiling panel/plank after all the M&E works is completed, corrected and agreed upon in writing. Installation of the ceiling panel/plank (600mm x 1200mm) are simply insert to the help in level position and then applying pressure on the dimple point.

8.3 Exposed Grid Ceiling (MFT)

• Plan the ceiling layout to provide even margins at the perimeter (grid space for ceiling panels at each end of the ceiling is the same).
• Centre the ceiling both ways to ensure centre lines are at right angles to each other and main runners are at right angles to purlins or joists.
• Fix wall angle trim to perimeter walls at the correct height of the ceiling and check that they are level. Mitre the wall angle trim (shadow line) around piers and columns.
• Fix suspension rod brackets to structural framing or concrete soffit to appropriate height at 1200mm maximum centers in each direction.
• Attach suspension rods (with suspension hangers attached) to suspension rod brackets previously fastened to supporting members, with rod end bent down into a hook.
• Attach the main runners to suspension hanger ensuring the hanger hook is firmly threaded through the top of the main runner.
• Adjust the suspension hanger or rod threaded to set the height of the main runners to a level line between the wall and wall angle trims.
• Insert cross tee runners intersecting main runners at 600mm centres.
• After suspension components are installed, fix light fittings, air register and blind boxes. Check all fittings for tightness and safety and insert ceiling tiles.
