Structural Risk Assessment & Method Statement

This Method of Statement is concerned to Planning, Preparation, Conduct and Method for the safe Excavation, Concrete Footings & Structural Work to the boundary walls of the property/building/facility.

will provide guidance to prevent injury to workforce involved in the excavation, concrete footings and structural works. It also provides a safe system of work (SSOW) to prevent any destruction to adjacent facilities/buildings. 

Unfortunately, underground construction work will always – genetically and unavoidably – cause some movement in the nearby & surrounding ground. A project that is poorly designed and/or constructed would bear to cause greater ground movement and, hence, have greater potential for damaging adjacent structures and or facilities. This compared with a well-designed and well-executed scheme for which ground movements have been minimized and controlled.

  • The collapse of temporary Structure.
  • Manual handling.
  • Contact with pigeons/ droppings.
  • Contact with Mobile Plant.
  • Use of Power Tools.
  • Lack of awareness of risk by staff.
  • Verbal abuse or assault.
  • Extremes of weather.

Who might be Harmed and How?

  • Roof operation & workforce, public, visitors struck by falling materials or flying objects. 
  • Agronomical disorders due to Manual handling e.g., back pain injuries if the staff try to lift objects that are heavy/awkward to handle. Improper and Incorrect lifting techniques may cause muscular injuries.
  • Due to water splashes, ingested water etc., staff is possible at risk of infection and illness. 
  • Roof operatives and other technical staff struck by moving vehicles.

Drywall Work Installation Method Statement

 Scope

The scope of the written Method of Statement for Drywall Work. Works are executed following the Contract Specification and safety requirements, related hazards and concerns are analyzed and safety precautions are implemented throughout the progress of the work.

Objective

  • Strict adherence to this method statement is critical to the health and safety of all manpower engaged in the work.
  • Any deviation must first be authorized by the site supervisor.
  • Work safely throughout the entire process.

Submission Documents 

Technical data, test certificates, installation instructions and valid Certificates for fire-rated assemblies for approval before commencement of work will be provided by the manufacturer.

Delivery, Storage and Handling

  • Coordinate deliveries to comply with the Construction Schedule and arrange for off-the-ground storage. Do not load any area beyond the safe design and recommended load limits.
  • Do not store product outside. Always try to stack gypsum/calcium silicate boards flat on a smooth, even and dry surface.

Site Conditions 

  • Install work only in areas closed and protected against the weather.  Provide appropriate Ventilation & Dehumidification (VD) to eradicate extreme moisture in the areas of work to ensure appropriate drying, curing of the compounds.
  • Try to never install such type of work in any area unless convinced that the work accomplished has dried out and that no more installation of damp materials is proposed.

Products

  • Gypsum Board of a selected thickness (12.5 millimetres, 15 millimetres, 16 millimetres or 19 millimetres) to be used.
  • Stud of selected width (49 millimetres, 62 millimetres, 72 millimetres or 92 millimetres) to be used which is determined by the architect in the specification.
  • Jointing Compound
  • Paper Tape

Installation Guide

  • Always Install metal wall framing as per the manufacturer’s instructions.
  • Complete and mark the wall position and make allotment for openings. 
  • Fix track channel appropriately and securely along the centre line of floor and ceiling at 600 millimetres centres with reasonable fixings.
  • Then cut the stud to an exact fit into the height of the needed and or desired wall height. Locate the first stud into the track channel, twist into position and fix to the abutting wall at 600 millimetres centres. Locate the next stud at 600mm centres to a friction fit within the track channel sections.
  • In grafting and or splicing the studs due to height recommendations, 2- stud members are boxed with minimum overlapping of 600 millimetres. For the designed partition, height more than the plasterboard length, an extra track channel adjusted horizontally to strengthen and support an infill panel is recommended and required.
  • Drywall partition above ceiling shall allow for cut out opening service such as ducts, trunk and cable trays.
  • The main contractor shall confirm and coordinate with all sub-contractors on the correct location and size of the openings. Any gaps around any pipe ducts through the partition shall be appropriately sealed with a proprietary Fire Smoke Stop System (FSSS).
  • If the full height partition had to be terminated below the ventilation duct route parallel to the partitions, the stud of the partition shall be secured to the support frame of the duct. In such installation services, space between the duct and reinforced concrete soffit and or rim required not to be sealed up.

Jointing

Support all internal and external corners/angles and Panel Joints (PJ’s) for wall surface with paper tape installed in and accomplished with Jointing Compound (JC).

First Coat

  • Using a trowel, apply compound to the plasterboard recessed joint formed by the recessed edge of the board. The compound should be applied 3 millimetres -5 millimetres thick to strengthen with tape bonding.
  • Centre the paper tape along the joint
  • Leave sufficient compound under the tape to achieve a good bond.
  • Immediately apply a thin coat of compound over the tape. This minimizes the probability of the tape edge curling or wrinkling which could cause cracking of the wall or installation.
  • Cover all fastener heads and allow the first coat to set/dry. Leave all joint and fastener
  • Heads with a smooth finish and feathered edges.

Second Coat

  • When the first coat has set/dried scrape back any build-up of the compound. Affix or apply a second coat of compound by utilizing a trowel. The second coat should be accomplished as flush as viable to the Board Face (BF).
  • Using a trowel, cover fastener heads with a second coat approximately 25 millimetres wider than the first coat.
  • Allow setting/dry.

Third Coat

  • When the second coat has set/dried, scrape back any build-up of compound along the joint, to give a smooth and level surface.
  • Apply a finishing coat with a trowel to a width of approximately 275 millimetres. A wet sponge (applicator) may be utilized on the joint edges to help gain a smooth finish.
  • Apply a finishing coat to fastener heads approximately 25mm wider than the second coat.
  • Allow setting/dry completely.

Incident/Accident Calculations-(TRIR, TIR, LTIR, LTISR)

Counting Accident Incidence Rates and Severity (AIRS) can help evaluate and rectify conditions that cause accidents.

Most of the Employers like to count monthly and or Quarterly Incident Rates (QIR) as well, and this can conveniently be done by utilizing incident/accident and hours-worked figures for mere the specially month or quarter.

A Severity Rate (SR) can be determined by substituting the number of lost workdays for the number of Recordable Injuries (RI).

Recordable Injures (RI) are those which result in fatal death, Loss of Consciousness (LC), drawbacks on the activity or motions the employees can execute, convert to other work, or Medical Treatment (MT) beyond First Aid (FA).
