Engineering Design

Chadwick Technology has been awarded Excellence in Engineering Awards by the Institution of Engineers Australia and Gold Circle Awards for Roofing Innovation from the National Roofing Contractors Association – USA. The design checklist for Chadwick Composite Systems is extensive and includes considerations of items such as:

  • Structural requirements
  • Deflection limitations
  • Dead load considerations
  • Wind load considerations
  • Thermal requirements
  • Condensation considerations
  • Hydraulic requirements
  • Fire resistance
  • Material compatibility
  • Sound absorption
  • Sound transmission loss
  • Installation efficiency
  • Buildability
  • Health and safety considerations
  • Material procurement


Much of the subcontract work we do involves on site manufacturing. Particularly for large projects, projects in remote areas, or where transportation of large fabricated components is not an option. On site manufacturing includes roll forming of structural decks and roof sheets, fabrication and painting of secondary steelwork, and glazed skylight prefabrication.  These techniques have been successfully employed on the following projects:

  • Abu Dhabi International Airport
    • Roll forming roof sheets
  • Dubai Metro
    • Roll forming roof sheets
    • Roll forming structural decks
    • Prefabricate skylights
  • Dubai International Airport
    • Roll forming roof sheets
    • Roll forming structural decks
    • Prefabricate skylights
  • Second Bangkok International Airport
    • Fabricate and paint secondary steelwork
    • Roll forming roof sheets
    • Prefabricate skylights
    • Prefabricate louvres
  • Singapore Expo Station
    • Roll forming roof sheets
    • Roll forming structural decks
    • Prefabricate skylights
  • Kuala Lumpur International Airport
    • Roll forming roof sheets
    • Roll form ceiling strips
  • Sydney Aquatic Centre
    • Prefabricate skylights
