Method Statement for Gypsum Board Installation to Ceiling

Gypsum Board Installation to Ceiling

1. Purpose of the Method of Statement

The purpose of this Method Statement is to highlight the main points in gypsum board installation to the ceiling as per the approved shop drawings, ensuring health and safety, perfection and durability. In which, there two types of the board to be installed, the Water Moist Resistant for T&B ceiling installation and the ordinary gypsum board as the interior ceiling board up.

2. Description of Work

The work methodology of installation covers various tasks e.g., ceiling, bulkhead, opening and other design described and mentioned in the work activity plan to cover the ceiling with the required & recommended dimension, elevations and levelness all following the shop drawings.

Standard and calibrated accessories, equipment and devices required in gypsum ceiling include the advised and required steel furring, C-channels, and the carrying rod that will fasten to the concrete slab.

3. Delivery, Storage and Handling

  1. To minimize the risk of deterioration, plasterboard should be transported to the site just before installation.
  2. During handling and storage, gypsum sheets should be transported in an ‘upright’ or vertical position with particular care taken to protect the edges.
  3. Gypsum/Plasterboard should be kept in tidy, balanced stacks off the ground/floor in a dry covered area. This will prevent sliding and minimize possibility of damage to board edges and surfaces

4. Installation

  • Before installing plasterboard, a building or facility should be completely examined, inspected and checked to ensure that the framing is plumb, level and square other trades have finished their ‘rough-ins’.
  • When the installation of gypsum/plasterboards is accomplished, recommended level of finish should be maintained.
  • Prior proceedings to install the plasterboard, a facility should be completely inspected/examined to make sure that the framing is plumb, level and square other trades have finished their ‘rough-ins’ appropriately and as per the required standards
  • The spacing of studs, joists or battens takes into account the spacing recommended by the linings given as per the plan schedule/methodology. When the installation is accomplished, the gypsum/plasterboard will comply with the required standard of finish.
  • Prior proceedings to install the plasterboard to steel framing, completely inspect/examine that the framing has been assembled and erected as per the manufacturer’s instructions. All contact surfaces of the steel frame are dry, tidy and free from external materials contaminants such as oil, grease and dirt.
  • Steel Furring Channels (SFC) are installed at correct recommended angles to the underside of joists using clips or other sources such as fasteners.
  • Anchor clips are utilized to adjust/install steel furring to a slab ceiling properly as per the design. 
  • Furring Channels (FC) should be spaced as per the sheet thickness provided in the Frame Spacing.
  • Installation of the celling must be done carefully as per the plan. 
  • Gypsum sheets should be set out to make sure the best coverage and to minimize butt joints and or waste from the installation material or ceiling.

Proper and essential Provision of control joints in walls and ceilings:

  1. at maximum 12 meters intervals in both directions
  2. at every change of material 
  3. over control joints in the substrate
  4. at every change of substrate material. 

Plasterboard should be adjusted/installed to the substrate using one of the below highlighted systems: 

  • Combination adhesive and fastener. 
  • Screw fixed only. Nail fixed only.
  • A variety of clips and or trims available for finishing corners, edges and joints of plasterboard appropriately to make neat sharp lines, reduces cracking and to offer a higher level of impact resistance. 
  • Trims may be installed /adjusted with nails, or with cornice adhesive and then stopped and finished with the normal 3-coat system.

5. Supervision

Installation is accomplished by the competent, skilled and experienced technical technicians (installer) who has expertise in board installation finishing. They are accompanied by unskilled general workforce. And all installation work is supervised by experienced supervisor. Site Engineer/Architects will be available for better and continuous communication & co-ordination with main-contractor, sub-contractors, and also look into the technical aspects.

6. Fixing Materials Used

  • Steel Framing.
  • Wall angles.
  • C-Channel.
  • Carrying Rod.
  •  Connecting Clip.
  • Black Screw (BS) to connect Gypsum Board (GB) and Steel Framing (SF).
  • Shadow Line by (Manufacturer Name), as the termination between wall and ceiling.
  • Gypsum Putty (GP) and Wire Mesh Tape (WMT) for the control joint in every board laid. 
  • Gypsum Board for the Installation.

7. Machinery and Tools to be Used

  • Screw Gun. (Makita or any other similar brand)
  • Iron Scissor Cutter for furring
  • Toolbox with spirit level, measuring tape, water level, right angle, plump, and other items.

8. Safety Procedures

  • All Health, Safety & Environment (HSE) rules & regulations will be adhered to strictly.
  • All the workforce will wear overalls, safety boots, safety goggles, heavy duty hand gloves and Hard helmets. 
  • Adequate lighting and ventilation will be ensured during the installation.
  • It will be made sure that the machinery, equipment, devices and or tools used are safe to use, and good condition is maintained before and after each work. 
  • Proper markings will be applied on the wall by setting plumb to determine the exact locations

9. General

The Sub-Contractor reserves the right to make any amendment to the method from time to time in consultation with the Main Contractor, depending upon the particular worksite conditions.
