4.1. Site Clearance
• It has been done before the commencement of any excavation or placing of fill material.
4.2. Mobilization
• Prior to entering the working area, all equipment and machinery will be inspected by safety personnel. Safety
personnel shall be responsible for preparing and providing relevant documents.
• All machineries, equipment and material shall be entering using the designated entrance gate.
4.3 Equipment Setting-up
• All material, machineries and equipment shall be located at designated area.
• Setting-up of equipment will be done by Supervisor by adhering to all safety measurement and requirement
outline.
• Upon completion of set-up, joint inspection will be carried out to satisfy all parties and ensure all relevant
equipment/machineries shall be complied with safety rules and regulation.
4.4 Survey
• Prior to the work commencement, construction drawing will be reviewed to check of its latest issuance for
construction and all essential details are given. It will be checked that the intermediate dimension agreed with the
overall dimension.
• The setting-out will be made at the beginning stage of the work by referring to the construction drawing and all

reference points will be made necessary for the entire work. This will be acquired and develop method of
checking and cross-checking on all setting-out operations. When principal lines and levels haste be set-out, it
would be advised to be the relevant persons.
4.5 Layout and Marking

•

For foundation excavation, leave the bottom layer of minimum 50mm undisturbed while mechanical
excavation and subsequently remove this layer manually when the blinding concrete is about to be placed.
This prevents softening or deterioration of the excavated surface. If hard strata appear then jack hammer and
breaker can be used.

4.6.3 Excavation Concrete foundations, Manholes and Miscellaneous Structures
