• Protection of flooring

Before starting of the first fix services of false ceiling clearance will be obtained from the contractor, consultant and MEP sub contractor as the first fix services of M.E.P above the false ceiling to be completed and approved. 

An area for mock up will be prepared for inspection and approval before proceeding with the overall installation. 

QAQC procedures shall be followed, WIR shall be raised, 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 angles 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 c/c and 300mm near the walls with 6mm dia concrete plugs or rivets and extra supports should be provided near the A/C duct if required Horizontal channels will then be fixed to vertical channels with self taping screw 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 screw from fisher supporting up to a weight of 50 kg per fix. Suspension system of the gypsum board ceiling should not be in direct contact with M.E.P. service especially A/C ducts.

Fixing of Gypsum Board:

Pavers Make sure that available interlocking tiles are as per the approval from client. Also ensure that color and thickness of the tiles are in accordance with the drawings and specifications. Prepare sub grade by leveling and compacting the graded surface to attain the required degree of compaction of the maximum dry density. Install the kerbstones to the target level and plumb, as shown in the drawings. Provide proper Hunching with mass concrete for the Kerbstones as per the finishing details. Upt-completion of necessary curing period, do the back filling by the sides of the kerbs. Take necessary care to avoid any disturbance in the alignment of kerbs during compaction. Make sure that sub base is of approved material and minimum 150 mm thick compacted to 95% of MDD (or as specified). It shall be spread evenly, watered, shaped and graded to the required grade and cross section Provide laying course with coarse sand (0-5 mm) to a minimum thickness of 50 mm. Do the laying work evenly and compact to the desirable compaction level. Lay the paving interlocking blocks or bricks in Herringbone pattern unless otherwise shown on the drawings. Ensure that the joints between interlocking bricks / blocks shall not exceed 3 mm. Compact the block paving using plate compactor, after each 20 square meter of lying. Brush fine sand over the paving stones, half filling the joints, fill the top half of the joints with betonies or any approved material and use plate vibrator for further compaction. Once the compaction is complete, remove all the surplus material and debris from the working area to make it clean and tidy. xO  win a Nissan Z 2021 2021 7 alumni alr
