5. Methodology 5.1

Clearing and Grubbing

The process of clearing and grubbing is the removal of all trees, bushes, vegetation, rubbish and any other relevant obstruction within the line of work. 1. Establish the survey markers to indicate the working area for the site clearance. 2. Produce a record of conditions that includes a photographic survey to be agreed by the Engineer, Landowners and any relevant authorities prior to commencement. 3. Takeout a topographic survey on land that may be affected by ROW operations and serve as a basis for final reinstatement. 4. Inspect Measure and Agree with the Engineer and the Forest Authority (Regional Directorate of Forest Affairs) where trees require to be felled. 5. Identify and Mark clearly all the trees to be felled prior to commencement of the operation. 6. Remove all the marked trees, bushes, vegetation, stumps and roots to their full depth, while ensuring that the following precautions are implanted: 

Minimizing the felling of trees and loss of topsoil.



Agree with the Engineer for any individual trees which have to be retained within the ROW.



Avoid unnecessary damage to the trees, crops, trunks and canopy by machines or other disturbances.



Do not totally remove the vegetation over the slop, to avoid the potential risk of soil erosion on the slope.

7. Construct temporary roads when needed, to provide better access to vehicles and equipment. 8. Remove unusable and hazardous materials accordingly to the following: 

Test any hazardous waste or material discovered and report to the Engineer before undertaking any action.



Remove or Dispose off-site all materials which are not considered of value by the Engineer.



Remove any loose boarders or materials located outside the ROW that may impose danger to the constructions.



Separate and Load all materials to locations shown on drawings or approved by the Engineer.



Obtain the written arrangement for the disposal locations outside the ROW from the owner or governmental authorities.

9. Backfill and Compact the cavities of the surrounding ground. 10. Maintain the surface in a clean, tidy and stable condition allowing it to fall water and to prevent ponding.

5.2

Removal of Existing Structures

The procedure involves the safe removal of all existing structures such as walls, fences, drainage, water pipes and cables while ensuring that alternatives are found to resume their existing functions. 1. Inspect Measure and Report to the Engineer for major structures, underground structures, manholes, wells and similar items to be removed. No action will be taken until the Engineer provides his instruction for disposal. 2. Backfill and Compact voids lift after removal with suitable material and compacted density similar to that in the surrounding ground. Fill with aggregate or sand in case of compaction is impractical, unless another treatment is shown on the drawings or instructed by the Engineer. Backfilling procedure is carried out in the Backfilling Method Statement. 3. Avoid unnecessary damage to fences, walls, hedges and property on or adjacent to the ROW. The places where a section of an existing fence is removed shall be supported to maintain the tension in the fence wire. 4. Flume existing drainage ditches and small watercourses across the running track to provide access to construction at crossed area and prevent water flow interruption. The temporary drainage management plan will be submitted separately considering the following precautions: 

Complete the diversion before the original drain is cut minimizing the interruptions to its operation.



Ensure that the free flow of water through the flume pipes is maintained throughout the project and that discharging location is suitable and agreed by the Engineer.



Make sure that fill material used to make up the grade level of the flume pipe does not spill into the watercourse and blocks the channel.

5. Ensure the following steps are undertaken where cables and underground services are detected:



Use cable detector and/or hand excavation (Trial Holes) where the presence of a cable is suspected.



Inform the Engineer immediately of the presence of any telephone or electricity cables that require moving and contact the relevant authority to arrange the work accordingly.



Mark clearly any underground services indicating the service details and depth.



Do not precede with site clearance operations at electric pole or below overhead cable until the cables and poles have been abandoned.

Topsoil

1. Establish survey markers to identify the working area in which the removal of topsoil is required. 2. Strip the topsoil to subsoil level or as instructed by the Engineer. 3. Use tracked equipment such as bulldozer. 4. Dispose and Stockpile the topsoil separately from subsoil or other excavated material for subsequent re-use in covering the required areas. Ensure that sufficient material for this purpose is preserved. 5. Place the topsoil in piles at locations shown on drawings or approved by the Engineer. Storing of topsoil shall be prohibited in the following areas: 

Under overhead electrical cables.



Areas where structures are to be erected or materials are to be stored.



Within 5 meters of a watercourse or ditch.



Within flood plains, unless gaps in possible water pounding areas are left in the stockpile to allow water to pass through.

6. Spread the topsoil over the required areas in a uniform pattern, followed by compaction and leave it with a neat and tidy appearance. 7. Grade sufficient portions of the ROW that are necessary to assist with subsequent construction operations after completion of clearing works and topsoil striping.

6. Risk Assessment Works shall be carried out in line with the issued Health and Safety, Control, Monitoring and Inspection Plan. Risk Assessment sheet of each activity shall be prepared by our specialist before commencing any activity.
