Prior to commencement of work contained herein, contractor shall obtain the relevant work permits from associated authorities.
Toolbox shall be conducted by the Supervisor.
Use of necessary PPE shall be checked and enforced by the safety officer. (Safety Glass, Safety Shoe, Helmet, Coverall, etc.)
Site Preparation and Mobilization Procedure
Earth Filling Procedures
Soil Test, Material Approval & Ground Preparation
Soil sample will be taken from the existing ground by Geotechnical Consultant and tested for Maximum Dry Density and Optimum Moisture Content as well as other relevant tests complying with procedures captured in Geotechnical Investigation Method Statement.
Contractor shall undertake the responsibility for clearing of site in order to remove any existing vegetation; steel, concrete, unused structure/elements identified for demolition, piping debris, loose windblown sand and other foreign materials as applicable.
Ensure all existing structures, foundations, etc. as captured above shall be entirely demolished, removed, transported and disposed off, to a debris yard or spoil heap designated by client or local authorities. All soft spots left shall be filled with suitable material and compacted as per specification.
Contractor shall take material approval for the fill material from client prior to transportation of materials. Rock fragments in excess of 100 mm, which may exist in fill materials, shall be removed by screening at site or by other appropriate method in compliance with the gradation limits indicated in standard specifications.
Suitable Earth Filling material prescribed by Geotechnical Consultant and approved by client for filling to makeup level shall be transported to site, stacked in heaps and placed in fill areas within work limits.
Mixing Spreading & Compaction
Water from approved source is to be added and mixed thoroughly such that the moisture content of the filling material is within ±3% of the Optimum Moisture Content if required as per Geotechnical investigation Results.
The mixed filling material shall then be spread in layers on the fill area by means of shovels and grader.
The first layer shall be in maximum of 200 mm thickness of loose materials and the subsequent layers shall be of 250 mm compacted thickness.
Spread fill material is compacted by roller with adequate number of passes to achieve the required compaction.
The compacted area shall then be tested for required Field Dry Density. Prescribed and approved fill material shall be compacted to a maximum density equal to 95% of Maximum Dry Density at OMC as determined by BS 1377 part 13 or to the density of the adjoining undisturbed material whichever the greater, in compacted layers not exceeding 550 mm.
Contractor shall take particular care in placing and compacting fill around protective membrane, pipes, cables as well as other exposed and underground structures as applicable to prevent any damage.
Grading & Cleaning
Earth filled areas not within routes shall be well graded and finished to specification.
Newly graded areas shall be protected against traffic and erosion.
All surplus soil and waste materials shall be removed and-disposed of, to designated locations as required.
Placing & Positioning of Prefabricated Site Office and Utilities;
The following outlines the procedures for construction of foundation base & steps
lifting, positioning & installation of Portacabin units as well as temporary services tie-ins as per approved Site Plan/Layout for Site Office, Security Office and Toilet spaces.
Erection of Site Office and Utilities shall commence only upon completion of the following;
Obtain necessary permit and approval to carry out works.
Prior to lifting operation, Safety Engineer shall thoroughly brief all work personnel involved with the lift as to their duties and responsibilities.
HSE department would ensure adequate safety provisions available.
Construction of Foundation Base and Steps
Required foundations shall be set out as per the approved Site Plan.
