How are the use of building components (pre-fabrictated wall panels, floor panels and roof trusses) incorporated into MR2? Clearly the best way to mitigate onsite construction waste is to prevent it from being delivered to the jobsite at all.

Studies have shown the use of building components (wood or steel) can reduce waste by 650% or more. In our case, steel components are even more efficient due to custom length roll formed materials. Steel recycling is also a very mature (and easy to accomplish) activity. Point is all these factors achieve the intent of the credit.

What is the best way to document the 'waste management' strategy of using components?
