Index

Scope - Reference documents – Definitions – Responsibilities – Safety – Method – Equipment - Attachment

Scope

The purpose of this method statement is to define the sequence of activities for the site preparation works related to the Company Petrochemical project. The extent of these activities are defined upon the attached site plan (Not included with this statement). Refer to indicative google photos.

Reference documents

Specifications for:

Site preparation,Excavation & backfill for underground installations,Fill, Grading and Paving,Testing Laboratory,Geotechnical Investigation

Definitions

GE Geotechnical Engineer

PSM Project Site Manager

SE Site Engineer

SOSafety Officer

QM/QEQuaity Manager/Quality Engineer

IS Infrastructure Superintendent

ST Survey Team

PPE Personal Protective Equipment

Responsibilities

It is an overall responsibility of the PSM to ensure that the site preparation activities are conducted according to the project specifications. PSM shall arrange all required resources.

The IS shall ensure that the site preparation activities are conducted according to this method statement as well complying with all specifications.

The GE shall ensure that the activities are conducted according to the project specifications and this method statement.

Safety

Prior to the commencement of any activities, the workforce shall receive a toolbox talk on the project site as well as on general safety requirements. SO shall ensure that the persons being inducted on site are well aware of the safety procedure to be implemented on site for the activity concerned.All persons upon the site shall wear PPE issued to them. Where possible hazards may arise from excavation activities, the necessary safety measures shall be taken to prevent accident or injury at all times. This may include provision of signage, barriers, watchman and lighting.Where work upon existing services is required, the necessary authority, permits and safety equipment shall be attained prior to the activity commencing. Scanning of existing services shall be conducted by suitable methods.

Method

The survey team shall locate and mark all services that are present upon the site (This includes above ground services as well as buried services). These services, (Electric, telephone, gas, oil, chemical, water etc), shall be clearly marked using stakes and warning tapes, reflected upon a site drawing and the issues raised with the client.

The survey team shall also mark upon the site plan all obstructions, structures and developments. Any obstruction encountered during excavation activities shall be plotted and recorded.

Where hazardous material is encountered, it shall be identified and isolatedin compliance with the safety procedures under SO supervision. The client shall be informed & hazardous material be collected and removed to a licensed tipping place. The details of the material and tipping arrangements shall be documented for review by the client as appropriate. Refer to Method statement Removal of hazardous materials.

Existing structures, fences and developments shall be demolished in a safe manner as site-stripping activities proceed. The necessary permits, approvals and permission shall be obtained from the concerned authorities prior to the commencement of the activity. The method of removal of these existing elements shall usually be conducted by dozer or breaker. Where necessary otherwise, discussions on site shall be made concerning alternate methods of removal when the full extent of these structures are exposed.

The removal of the topsoil shall include all vegetation and rubbish material from the work site.

Prior to the start of topsoil removal, the surveyor shall peg out the haul roads to be used by the construction equipment to execute all the site preparation activities. These roads shall be constructed by leveling of the existing terrain. Grade pegs shall be set to an agreed grid to indicate existing grade and reduced grade. Dependant upon the quality of the existing soil where the roads is to be built, suitable compactable fill may be imported or re-located from other parts of the site. The material shall be approved by the GE & QM/QE jointly.

These roads shall be maintained as the work proceeds.

Where required, water shall be spayed for dust control.

For general removal of the topsoil activities using appropriate equipment, the areas concerned shall be excavated and graded to levels that ensure adequate surface water drainage. The GE/QM/QE shall monitor the activity to ensure that the topsoil material is removed. Sampling and testing of the resultant material shall be conducted for specification compliance & proper compaction.

Upon completion of the topsoil removal activities where appropriate, the exposed surface shall be scarified, moistened and compacted to achieve the required density criteria. The areas shall be divided into manageable sections that be defined upon sketches. The GE shall monitor and test all sections. The results of the tests shall be recorded upon the relevant QC format. The number of tests conducted shall reflect the specification requirement.

In excavation areas, the GE shall review the material to be excavated to ascertain its suitability for re-use as fill material. This excavated material shall be transported to areas that require filling. The material shall be deposited onto the areas to receive filling, leveled, moisture conditioned and compacted. If necessary, stockpiling may be required.

The excavated areas shall be divided into manageable sections, which be defined upon sketches. The excavated areas shall be monitored by the GE to ensure that any unsuitable material does not appear. Where unsuitable material appears, it shall be removed. The excavated formation surface shall be treated by scarification, moistened and compacted according to the specification criteria. All areas shall be tested and the results recorded.

Where areas are to receive fill, the material that has been excavated shall be transported to the fill area, tipped, leveled, moisture conditioned and compacted. The material shall be spread and leveled in 200mm layers. The areas to be filled shall be divided into manageable sections that be defined upon a sketch. The fill layer shall be moistened and compacted to achieve the required specification criteria. No further fill activity shall be conducted upon an area that has not been approved and released by the GE. Attention shall be observed at edges and slopes, to ensure that compaction criteria are achieved. Additional layers of fill material shall be placed similarly as described above until the desired elevation has been achieved.

Production procedure.

Verification exercise for fill activity had been conducted to establish the economical and effective method for the fill activity.

Import and place fill to controlled areas of approximately 25m wide by 100 - 150m long.

Spread and level the imported fill.

Add water to the fill layer by passing the water tanker over the fill layer. The water tanker should pass over the layer twice.

A time gap of approximately two hours is allowed for the water to soak into the fill material.

The layer is now mixed with the grader until a uniform blend of moist material is achieved.

Additional water is added by passing the water tanker over the layer in a uniform sequence. A time period of approximately one-hour is allowed for this water to soak into the fill layer.

The fill layer is mixed again with the grader leaving the fill level to the correct grade.

Vibrating rollers shall now compact the fill layer in a logical sequence that compacts the fill layer uniformly.

Testing of the layer shall be conducted according to specification requirements.

Equipment

Dozers & Graders, Vibrating drum rollers, Dumper trucks, Excavators & Loaders, Water tankers

Attachment

None.Refer to indicative google photos as incuded as a facility. Assume there was nothing prior to construction & whole site was filled for preparationworks.
