  • product testing

    As part of the development process, all Chadwick Technology’s new products are extensively tested prior to manufacture and application. Testing facilities used by Chadwick Technology include:
    Testing can be for a variety of performance requirements which may include:
        Structural Efficiency
        Pressure Resistance
        Acoustic Performance (sound absorption and sound transmission loss)
        Impact Resistance (e.g. hail etc)
      All testing is undertaken under the supervision of Chadwick Engineering Staff, together with our Engineering and/or Acoustic Consultants.

  • Engineering Design

    Chadwick Technology has been awarded Excellence in Engineering Awards by the Institution of Engineers NSW Australia and International Gold Circle Awards for Roofing Innovation from the N.R.C.A. of the USA. The design checklist for Chadwick Composite Systems is extensive and includes considerations of items such as:
        Structural Requirements
        Deflection Limitations
        Dead Load Considerations
        Fire Resistance
        Material Compatibility
        Sound Absorption
        Sound Transmission Loss
        Speed of Erection
        Construction Safety Considerations
        Product Availability
        Hydraulics etc.
    We also prepare Budgets and Cost Feasability Reviews. Advanced Engineering Technology is evidenced by the range of unique light gauge rollformed structural products that have been developed and our knowledge of composite action of many of our designed systems.

  • Manufacturing

    Manufacturing Philosophy Chadwick Technology has developed skills and techniques for on site product production. Particularly for large projects, projects in remote areas, or where transportation of large fabricated components is not an option, our preference is for product production adjacent to the work face. This philosophy has been successfully employed on the following projects:
        Jin Mao Building, Shanghai, China
        Hong Kong International Air Terminal, Hong Kong
          Second Bangkok International Air Terminal, Thailand
            Kuala Lumpur International Air Terminal, Malaysia
              Singapore Expo Railway Station, Singapore
                Kranji Racecourse, Singapore
                  Dover Railway Station, Singapore
  • Case Studies

      The Chadwick Factory for this project had a covered floor area of approximately 2,500m2 and housed sophisticated roll forming equipment capable of the production of stainless steel roofing profiles and caps and also had the facility for “tapered rollforming”. This factory produced 150,000 lineal metres of rollformed product for the roof and nearly 600,000 lineal metres of ceiling panelling.


  • Case Studies

    Second Bankok International Air Terminal

      For this project we constructed an on site factory with a covered floor area in excess of 10,000m2.

      Within this factory we undertook manufacturing and assembly of:

        Light Gauge Structural Sections (including painting)
        Skylight Manufacture, including glazing
        Rollforming of roofing profile
        Construction of composite roofing components
        Fabrication and cladding of sun louvres
      This factory employed approximately 300 people for 12 months
      and ultimately was demolished on completion of the work.
  • quality Assurance

    Chadwick Technology is not certified with any specific Quality Assurance Programme.
      We regard this as an advantage. Because of the variety of projects, the various geographic locations, the locations of the project design offices, we believe it is more appropriate to construct a specific Quality Assurance Package for each individual project.

      Our Quality Assurance Programme is normally developed around ISO 9000 and is developed to have an appropriate interface with our Client’s Quality Assurance Programmes with all of the appropriate requirements for “traceability�? and product review included.

      Our Quality Assurance Plans cover all stages of each project including Design and Engineering, Material Procurement, Product Manufacturing, Project Staffing, Systems Review, Testing and our Staff is trained in the application in all of the appropriate paperwork associated with these systems.

      Our Quality Assurance Programmes have been “Third Party�? reviewed by our Clients, external Consultants, Government Departments and Major Contractors and we have been congratulated on the appropriateness of the format we use.
