Adequate access and egress should be provided to the site for work. All the personnel should wear basic personnel protective equipments. All the equipments, tools and tackles being used for the work should be in good working condition and maintained. All the personnel will be provided with toolbox talk on the procedures to execute the work safely.
Necessary risk assessment of the activities is reflected in the enclosed risk assessment.
Formwork Procedure
- All material delivered to site shall be visually inspected for straightness, finish and defects prior to use.
- Setting out shall be done by the surveyor prior to proceeding with formworks.
- Each type of form work for the raft, column, beam and slab shall be erected as per approved shop drawings.
- Prior to use formwork and supporting timber shall be checked for damage, surface condition and warping.
- Material shall be protected as necessary from the elements during transportation and storage.
- Design calculation for slab system shall be performed and submitted to consultant for approval.
- Certified and well trained manpower shall be deployed for all types of formwork erection.
- Inspection shall be done by the supplier / third party prior to proceeding.
- Care shall be taken to ensure that any formwork system is installed and supported correctly when applied on site conditions may vary. Visual inspection shall be carried out by the construction manager use for each element to ensure support provided is adequate for actual site condition. Every leg of scaffolding should be checked for tightness, rigidity and proper bracing both ways.
- Ensure that erected formwork is watertight to avoid any slurry leakage.
