QA/QC procedures shall be followed, inspections shall be carried out at different work tiers and clearances shall be obtained at progressive levels as mentioned therein.

Fixing of Suspension Grid

  • I angle as per approved materials and section details of false ceilings will be fixed on level markings with self-taping screws and royal plugs @ every 400mm c/c and at 100mm near the wall corners and joints of angles
  • Vertical support of primary channels or 3.5mm dia G.I wire with approved materials and section details will be fixed to concrete slab @ 1000mm and 300mm near walls with 6mm dia concrete plugs or rivets and extra supports should be provided near A/C ducts if required.
  • Horizontal channels will then be fixed to vertical channels with self-tapping screws.
  • For areas where the suspension height is much more than typical like the toilets, the C-channels 38X10mm shall be used as vertical support, the channels shall be fixed to the slab with high screws from fisher supporting up to a weight of 50 kg per fix.
  • The suspension system of the gypsum board ceiling should not be in direct contact with M.E.P. services, especially A/C ducts

Fixing of Suspension Grid/Frame

Before starting the Gypsum Board fixing services of false ceiling clearance will be obtained by the contractor, consultant, and M.E.P sub-contractor, services of M.E.P above the false ceiling to be completed and approved as well as inspection of the suspension frame of false ceilings should be carried out by the consultant and should be rectified to comments if given by them:

  • Extra support should be provided around the access panel.

Finishing of Gypsum Board

  • Apply joint filler in all the joints to fill the gaps
