3.10 Construction Loads 

Construction loads on a building include the wind load on a partially clad or braced roof or building. Depending on the method and sequence of construction, it can be greater than the load on a completed building.

Other forces contributing to construction load include:

  • The intensity of internal wind pressures due to a temporary absence of ceilings, walls and glazing.
  • Storage of roof cladding on the structure. Bundles of roof cladding should be placed so they do not cause overstress in purlins.
  • Any scaffolding above an existing roof must be designed to avoid damage to the roof structure or coatings.
