What is a false ceiling?
A false ceiling or alternatively called drop ceiling is a fixed framework made of either aluminum, metal or wooden batten covered with either material like Plaster of Paris, gypsum board, plywood, PVC sheets, wood, metal ceiling tiles, glass, mineral fiber, etc. hung below the main ceiling.
What are the Benefits of the false or drop ceiling?
- Lighting efficiency
- Conceal wiring for overhead fixtures, plumbing, air-conditioners, and sprinkler system
- Energy efficiency
- Thermal insulation
- Sound insulation
- Aesthetics Purpose
As part of QA documentation in the construction project, here is a sample of method statement that can be formatted and use for the submission.

2. The site engineer is responsible to execute the installation work as per the approved MS. QA/QC engineer of the subcontractor is responsible to ensure that work has been done as per specification and inspections are done as per the approved ITP. Safety officer of the subcontractor is responsible to ensure that all personnel on site are to abide by the project safety requirements.
6. EQUIPMENTS & TOOLS / MANPOWER / MATERIALS
6.1. Plant & Equipment Requirement
Following tools will be used for installation of suspended false ceiling works.
1. Drills with bits for concrete and metal
2. Screw gun – Power tool that drives all types of gypsum board screws through gypsum board and into framing or substrate
3. Powder-actuated tool ( E.g. Hilti Gun fastener)
4. Chalk line
5. Sprit level
6. Metal cutting scissors
7. Measuring tape – A steel retractable measuring tape, usually 25 feet in length.
8. Gypsum board T-square –Square edge for measuring and cutting gypsum board to length and for cutting out holes for square outlet boxes and other openings.
9. Utility knife – the Standard cutting tool with replaceable/reversible blades for scoring and cutting gypsum board.
10. Hammer – Drives nails through gypsum board into wood framing.
11. Keyhole saw – Small triangular saw for cutting out holes for outlet boxes, pipes, and other penetrations.
12. Assorted trowels and taping knives – Bladed tools for applying and smoothing tape and joint compound over joints and fastener heads.
13. Tray / Box to contain joint compound while finishing joints and fastener heads.
6.2. Manpower Requirement
1. False ceiling technician
3. Supervisor/ Foreman
4. Site Engineer
6.3. Material Requirements
Following materials will be used for installation of suspended false ceiling works.
1. 12.5mm thick regular gypsum boards
2. 600x600x6mm thick calcium silicate tiles
3. 0.55mm thick suspension of framing elements
4. T-24 exposed GI suspension
5. 0.5 mm thick 600mm x 600mm Aluminum tile
6. Main Runners and Furring Channels of 0.55mm thick
7. PROCEDURE / METHOD TO BE EMPLOYED
7.1. Site survey
1. The receipt of the shop drawings approved the consultants the site will be surveyed and any discrepancy found will be notified to the main contractor for clarification.
7.2. Setting Out
1. Setting out and marking will be done as per approved shop drawing ceiling height of various areas shall be marked based on the benchmark provided by main contractor level will be transferred on all the corners and chalk lines will be marked.
7.3. Fixing Of Wall Angles
1. The wall angles will be fixed along the marked ceiling line depending on the substrate at 600mm to center spacing. Before fixing the wall angle the substrate has to receive necessary finishes as per the finish schedule.
7.4. Fixing Of Hangers
1. Fixing of hangers will be done as per the approved shop drawing layout details and using hanger anchorage devices of the soffit as per approved material submittal. The position of the hangers will be marked on the soffit of the slab, which has to be reviewed by main contractor site engineer upon receipt of MEP clearance hangers shall be fixed at a spacing of 1200mm centres on both the directions where MEP services are clashing with fixing hangers, additional supplies shall be provided by agreeing with main contractor on site.
7.5. Frame Work
1. The framework will be done according to the approved shop drawings and with approved materials. Framing members such as Main Runners and Furring Channels of 0.55mm thick shall be placed as a spacing of 1200mm and entries respectively. Heavy recessed fixtures should be independent of the ceiling framing stems.
7.6. FrameWork Inspection and MEP Clearance
1. Upon completion of framework, respective areas shall be offered for main contractor and consultant inspection. Inspection request will be raised on prescribed formats for first and second fix of ceiling. Written clearance for MEP and associated works to be different stages for the uninterrupted flow of our works. Upon receiving the approval and MEP clearance. Void closures shall be started by gypsum board installation. Gypsum boards of specified type (Regular) shall be applied to the framing using gypsum screws at 200mm. For tile ceiling, the void closure will be done by placing calcium silicate tiles on the complete grid work.
7.7. Taping and Jointing For Gypsum Board Ceilings
The following coat will be applied over the joints.
1. First Coat / Jointing Coat
2. Second Coat
3. Third Coat
1. First coat is initial jointing process where the fiber tape is fixed over the thin joining compound applied over the joints. Another layer of jointing compound application would be done over the tape. This would be approximately 75mm wide. Screw heads also will be covered by the application of the joint compound. The second and third coat will be applied successively after having dried the previous coats. Each successive coat to be feathered 40mm beyond the previous layer sides of the joint. This would be sanded smooth after drying and leave for receiving decoration by following trades.
7.8. Final Check-Up
On completion of taping, jointing and sanding subcontractor supervisor will check the level and make sure that is in true level and the work is within the tolerance limits.
7.9. Cleaning and Handover to the Main Contractor
1. When all our activities are completed, the area will be clean thoroughly. Once the cleaning is done and approved subcontractor’s site in-charge a “Request for inspection” could be raised by him to main contractor for their acceptance to issue the substantial completion of works certificate. The area then would be handed to the main contractor or the succeeding contractor for further finishes/decoration.
8. HEALTH AND SAFETY HAZARDS:
Specific safety measures have to be followed as applicable, and all the safety measures are covered separately in the Project Safety Plan.
