Interarch Certified Builder Correct Procedures of Managing & Handling Material at Site

Material Loading /Unloading & In transit

  • Materials to be handled at site
    • Structure Components
    • Sheeting Material
    • Hardware
    • Accessories
    • Other misc. components
  • Space for unloading must be identified & should be marked in client's Plant Layout drawing to avoid re-shifting and damages.
  • Upon receiving the material at site arrange the Crane & Sling / Clamping jaws.
  • Match the physical material in trailer with packing list.
  • While loading and offloading, care should be taken to avoid throwing of the material as it would result in deformation and damage.
  • Client receiving (in shippers list, GR, Invoice) must be taken for each and every lot. Lot wise Material Verification Report should be prepared and any variations must be reported immediately.

Material Stacking

  • Material stacking must be planned in grid wise basis with proper barricading as handling of material can be difficult at large sites.
  • Procedure
    • Lift the first member in proper manner by crane & place it over wooden planks (at regular interval but not more than 2 meter) at leveled ground.
    • After placing first member, lift second member & place over first member. Planks on each member should be placed in one line.
    • Stack the total material in such a way that they should be easily traceable & moveable to erection area at the time of erection.
  • For Sheeting - do not stack more than five bundles on top of each other.
  • Sheeting bundles should be stacked in a slope to avoid water logging

Material Storage

  • Hardware & other small accessories must be stored in a covered area.
  • There should a separate store for all inflammable items like Thinner, Paint & Diesel etc.
  • Wooden pallets should be stacked at a location which is away from inflammable material storage area.
  • Wire mesh rolls should be stored in an upright position and not flat on the floor as due to its own weight while stacking, it is liable to get pressed and loose its roundness. This would result in deformed mesh when it is opened for laying.
  • The rolls should be stored indoors and under cover where there is no possibility of contact with rain water or moisture as it can cause damage.
  • The rolls should also be stored away from any acidic fumes as it is liable to corrode if it comes in their contact.
  • GP coils must be stored over wooden planks vertically and covered with HDPE cloth or canvas.

Handling and Storage of Fiberglass wool at Site

  • The insulation should be inspected upon arrival at the job site to ensure that it is exactly as ordered. If there is anything wrong with the insulation, it should not be installed and the supplier should be contacted immediately.
  • Always follow Insulation manufacturer storage Recommendations
  • Insulation should be stored in a dry, covered area.
  • All packages should be elevated above the ground, preferably on a flat surface, to prevent contact with surface water accumulation.
  • If the weather permits packages can be left uncovered during the day, but should be protected at night with HDPE cloth or canvas.
  • Whenever possible, the insulation should be used as soon as possible after it arrives at the job site. The sooner the insulation is installed, the less likely it is to get damaged in storage.
  • The facing should be protected from tears and punctures to maintain continuity of the vapour retarder.

Things to remember while Loading & Unloading of material at site:

  • Crane & Sling/ Clamping Jaws/ Nylon strap etc should be of sufficient capacity to lift the required load/material
  • Match the material in trailer with the packing list before unloading
  • Size specification should not be removed from crates / packet and bundles
  • Nylon Strap to be used for unloading the sheeting material / crates etc.
  • Structure material should be unloaded by using sling with rubber packing on the edges
  • Long length items more than 8 meters in length should be unloaded with the help of spreader beam
  • Tag/Guy rope to be used at the end of both members for avoiding free movement
  • Ground should be leveled and compact for storage
  • Wooden Pallets should be placed at equal distance to avoid distortion of material
  • After lifting the first member/ bundle in proper manner, lift second bundle and place it over the first pallet member/bundle.All wooden pallets should be in one line and equidistant i.e1.5 to 2.0 meters.
  • All galvanized material, hardware and critical bought out items such as insulation, weld mesh, hardware etc. should be stored in covered area or with water proof tarpaulin.
  • All Bundles items i.e. Purlins, Rack/ Eave Angle, Sheets etc should be kept at height and slope of 5.
  • Do not stack more than four sheeting bundles on top of each other.
  • Stack the total material in such a way that it should be easily traceable & moveable to erection area at the time of erection.
