1. For the portal frame/roof system:

1. outline the construction method and sequence to construct the frame and roofing

• from the drawings the builder sets out the structure rom the controlling dimensions. This is achieved by tying string line from profile to profile and from where these lines intersect the builder places the center of cage.
• Surveyor then checks the setup and makes sure they are correctly placed. Even being only 5mm out can cause a massive and costly disruption.

1. what codes and/or Australian Standards are relevant to the compliance requirements for this type of structure?
2. prepare an Inspection & Test Plan for ensuring the compliance of the roof construction with project documentation.
