tools and related work practices.



Procedures:



6.1 General Requirements for false ceiling & PARTITIONS Installation.





 All joints shall be filled and tape properly after using joint mesh.

 Partitions lay out should be inspected by Main contractor before starting truck fixation.

 Partition type should be identified before starting the work in each area.

 Partition works should be coordinated properly with M.E.P subcontractor specially after fixing our

structural framing and just before closing the second layer of board.

 Gypsum Board should be fixed staggering in same horizontal level.

 All joints tape shall be even and shall not exceed the level of board by removing paper from the

edge which doesn’t have sloped edges but not for chamfered edge which already to receive filling

materials.

 Where applicable, provide bulkhead as indicated on the approved shop drawing.

 Where applicable, provide curtain box/ divider box as indicated on the approved shop drawing.

 The tiles cut piece shall be carried out as per the approved shop drawing and shall not be less

than 30 cm (not less than half tile).

 The tiles cutting and formulation of cut piece shall be formed by using suitable cutting machine to

avoid any irregular edges for the cut pieces.

 All necessary coordination with the mechanical and electrical works shall be carried out in three

stages:

 Before starting suspended GI Furring ceiling system.

 Before fixing Gypsum board.

 After fixing Gypsum board.

 Coordinate the finish Ceiling level with the adjacent levels, and adjacent window.

 The installation of the tiles and the Gypsum Board shall be subjected to the construction drawing,

the approved shop drawing, and mock-up to be done.

 Bulkhead edges and corners shall be provided with proprietary coved mesh accessories with nice

finish tapped.

 All coordination process should be supported by formal clearance letter from M.E.P. subcontractor

in all stages, main contractor and final approval from the consultant.

 Any temporary opening required by M.E.P. should be by marking on gypsum board before

finishing stages.(Joint Treatment)

condition after M.E.P. service had been installed.

 Any materials at slab concrete soffit base incompatible with the support shall be removed by main

contractor.

 All block works, plaster, at least primer paint, to be completed till the slab soffit.

 Fire sealant to be applied wherever applicable.





6.2.2 Fixation Suspension System (70 % of job):





 Fixing the wall angle by (Hilty Gun steel nail) to the wall matching the level which had been

marked before starting the fixation.

 Submit first WIR-1 for approval.

 Fix the Main channel supported from sofit of lab using Hilti Material fixation (X-CC DNI 27 P8) as

approved in our submittal from engineer.

 Horizontal main channel fixing to dropped supported from top by using ½” white screw DD 02

(Hilti)

 Furring channel fixing to horizontal main channel perpendicularly by ½” white screw DD 02 (Hilti)

 Approval for suspended system ceiling should be obtained from the engineer after inspected from

Q/C engineer, and the consultant.

 All MEP Access panels required to be marked on the slab soffit for the engineer’s approvals.

 Acceptance latter from M.E.P. subcontractor to satisfy that all support should not object any

M.E.P. services in future.

 Submit second WIR-2 for approval.





6.2.3 Fixation of Gypsum Board (30 % of job).

 Fixing with the cross tee angle perpendicularly with main tee.

 Acceptance latter from M.E.P. subcontractor to satisfy that all support should not object any

M.E.P. services.

 Submit second WIR-2 for approval.

 Approval for Suspended System Ceiling should be obtained from the engineer





6.3.3 Fixation Gypsum Tile (40 % of the job):



 Lay the Gypsum tile.

 Mark all M.E.P. services which have to be cut before fixing the tiles.

 Cutting tiles opening accordingly to M.E.P. subcontractors and hold in store until permission to fix.

 Fixing and cutting in proper way of tiles as per approved shop drawings.

 Before announcing the final inspection, all tiles should be installed.

 False Ceiling tiles will be ready for engineer inspection.

 Submit second WIR-3 for approval.



6.4 Gypsum Partitions:



6.4.1 Preparation prior to installation.



 Survey by our engineer to assure the work is ready to start accordingly.

 Partitions Lay out should be marked on the floor by our engineering team.

 Any materials at slab concrete incompatible with the support truck should removed by main

contractor.

 Cleared approved shop drawings for partitions type’s & partitions lay out should be available with

our construction manager and project engineer at site.





6.4.2 Fixation Suspension System (70 % of job):





 Submit first WIR-1 for Lay out approval.

 Fixing the truck by (Hilty Gun steel nail) to the floor matching the approved lay out on the floor

which had been marked before starting the fixation.

 Fix the first and last vertical stud only for each expected wall partition and in same time fix the top

truck also for check alignment and verticality assurance.

 Continue fixing stud channel 400 mm c/c fixing to top and bottom truck supported by using

½” white screw DD 02 (Hilti) and paralleled to basic stud which will be ad bench mark for it.

 Horizontal truck channel fixing as support for stud each 1200 mm as standard for two purposes,

structural and to get raw cool insulation.

 Around openings doors and windows should be taken in considerations for extra support channels,

as horizontal truck and vertical stud in position to receive flat faces, and to provide white wood

fillet 50 mm as required to receive support screws.

 Approval for structure framing partition system should be obtained from the engineer after

inspected from Q/C engineer, and the consultant WIR-2.

 Our site engineering team will give enough time and coordination for M.EP Subcontractor to start

his work in this critical time to fix his pipes and conduits.

 All MEP Access panels which it might be required to be marked on the structural framing to give

us chance for sufficient support in this stage.

opening.

 Submit fourth WIR-4 for approval, Got formal approval for fix second layer gypsum board from

engineer before closing the partition.

 After cutting only, we can start joint treatment and assuring that the joint level should

not exceed the board level.

 If required in joint area, paper should be removed and hanging the board before treatment with the

joint compound.

 In same time of filling joint compound (Boral), Joint mesh (Boral), should be fixed and matching

same level of Gypsum Board Ceiling.

 Gypsum ceiling ready for engineer inspection.

 Submit fifth WIR-5 for approval.

 In case of double layers board, we can hold the second layer fixing up to final stage of works to

Page 8

avoid any damages it might be happens.

 So same procedures of finishing board we can go throw and to do WIR as well.





6.5 Protection of finished works



 After the final inspection for Gypsum Board Ceiling, and Gypsum Partition walls just to care that

nothing to spoil the surfaces as much as possible especially from M.E.P. subcontractor.

 We recommend not starting final finish touch unless we assure that M.E.P subcontractor had been

successfully finished his works.

 For double layers gypsum partitions we recommend that to hold the second layer of board fixing

up to final stage.
