• Measuring tapes
• Tamper
• Spanners
• Torch

The capacity/size of the above tools and equipment shall be judged in accordance with site conditions, requirements, and availability at the time of execution.

SAFETY & HEALTH

Safety of the personnel and properties is to be given prime importance and all the works are to be carried out without causing any accidents or property damages.

Formworks involve the following activities:

• Storage
• Transportation
• Fabricating and fixing
• Lifting of formwork at the Site
• Removing of Formwork

Adequate access and egress should be provided to the site for work. All the personnel should wear basic personnel protective equipment.

All the equipment, tools, and tackles being used for the work should be in good working condition and maintained. All the personnel will be provided with a toolbox talk on the procedures to execute the work safely.

Formwork Procedure

• All material delivered to the 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 formwork 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.
• Upon request Design calculation for the slab system shall be performed and submitted to the consultant for approval.
• Well-trained manpower shall be deployed for all types of formwork erection.
• 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.
• Concrete forms must be cleaned and any foreign material removed before concreting.
• Ensure that sleeves and openings for all the MEP services are provided as per approved shop drawings
• Formwork shall be checked for alignment, verticality, and leveling prior to proceeding with concrete pouring
• The inspection shall be raised for the CONSULTANT inspection and approvals before proceeding to concrete pouring.
• Striking of formwork shall be in accordance with the specification section of cast-in-place concrete.

Formwork Removal:

• Obtain approval from the consultant before striking formwork for concrete work.
• Make sure the concrete has reached minimum sufficient strength before removing the formwork.
• While removing the formwork, ensure adequate safety measures are taken.
• Formworks shall be cleaned as soon as they have been struck.
• A good storage system is important to ensure that the formwork can be reused.
• Code numbers can be used to identify them easily when they are needed.

Removal of shuttering / deshuttering time period should be as detailed below:
