Site Planning & Preparation
Establish benchmarks as needed. Prepare plans/drawings reflecting the actual site, equipment positioning and layout during the activity and the detailed position of the equipment.
Site Management Plan & Access Routes
• Secure a copy of the necessary permits from the client.
• 3rd party certifications attesting the reliability of equipment and operators will be available prior to the start of work.
• Identify the location of the stock pile area.
• Identify access routes for the transport.
• Prepare the necessary traffic management plans for the activity reflecting the flow of traffic going to and from the respective areas. Indicate in the traffic management plan a safe pedestrian access where staff and employee can access the site/area to check the productivity. Drivers, operators, and all staff shall follow the traffic management plan strictly.
Work Methodology (Execution)
Handling Of Cables and Wires
• Upon the delivery of the cables and wires the condition of the drum should be inspect. If there is any evidence of drum damage, the damage must be repaired prior to storage to avoid over-tensioning of the cables.
• For loading and unloading of cable drums from vehicles, a boom truck should be used. For small sized cable drum a suitable ramp shall be used, provided no damage is likely to be caused to the cable or to the drum.
• When lifting the cable drum using a crane, a spreader bar must be used above the drum to prevent inward pressure in the top of the drum flanges.
• When the cable drums have to be moved over short distances, they should be rolled in the direction of the arrow marked on the drum.
• When the cable drums have to be moved over long distances, the drum should be transported in vehicles with rated capacity to handle the cable gross weight.
• Cables shall be properly secured using ropes while transporting.
Storage Of Cables and Wires
• Prior to storage of cables, field test shall be performed. Perform continuity test and insulation resistance test on each cable. Applied potential shall be 1000vdc for 600v rated cables. Test duration shall be one minute.
Note : Testing equipment should be calibarated.
• The cable drums shall be stored in a well drain, hard surface, so that the drums do not sink in the ground causing rot and damage to the cable drum.
• The drum shall always be stored on their flanges, and not on their flat sides.
• Both ends of the cables should be properly sealed to prevent ingress and absorbtion of moisture by the insulation during storage.
• The cables shall be installed in a place protected from rain and direct sunlight. There should also ventilation between cable drums.
• For long time storage of cables, periodical rolling of drums once every 3 months through 90 degrees shall be done. Rolling shall be done in the direction of the arrow marked on the drum.
• Damaged battens of drum should be replaced.
• Before transporting to the field, a physical inspection shall be carried out to ascertain whether there is any evidence of damage.
