Detailed Case Study

Scope of Works and Services:

The services provided by Modern Glazing Group Pty Ltd were comprehensive, covering the full supply and installation of all aluminum windows and doors for the project, including related components and finishes. The total subcontract sum for these works was $492,948.00 (excluding GST).

Key deliverables included:

• Design and Fabrication: The subcontractor was responsible for the design of a complete window and door system that complied with project requirements, Australian Standards, and the NCC/BCA (National Construction Code/Building Code of Australia). This included preparing and submitting all workshop drawings for approval. The design had to meet specific acoustic report requirements, as well as NATHERS 7 Star PCA (Property Council of Australia) and BASIX requirements.

  
  

• Materials: The contract specified materials such as Capral 400 and 425 Narrowline profiles or approved equivalents. It also required specific powder coat finishes and the use of toughened/laminated safety-grade glass in accordance with Australian Standards.

  
  

• Window and Door Systems: The scope included supplying and installing various window and door types, such as windows W01A to W16 and doors D04A to D36. All windows were to be key lockable with additional ventilating lock points at 50mm and 100mm from the closed position, and awning windows were to be restricted to a 100mm opening to comply with fall prevention tests (AS5203).

  
  

• Associated Hardware and Screens: The scope encompassed all necessary hardware, fly screens for all windows and sliding doors, and security screens for ground-floor sliding doors and accessible windows. Fly screens were required to have a permanent safety warning label.

  
  

• Installation and Finishing: The subcontractor was responsible for on-site installation, including the provision of all fasteners, secondary support structures, and flashing. They were also required to perform a trade clean, water-test the works, and rectify any damage until the main contract's practical completion.

  
  

• Compliance and Documentation: Modern Glazing was required to submit and obtain all necessary notices, permits, licenses, and approvals. A Quality Assurance Plan and a project-specific Safe Work Method Statement (SWMS) for all high-risk activities were mandatory submissions before commencing work. The company also had to provide a 10-year warranty for framing, glazing, and powder coating, a 5-year warranty for window security and hardware, and a 2-year warranty for sealants. All project documentation, including as-built drawings and operation and maintenance manuals, had to be provided upon completion.
