FAQs about MRc1.1 :

What building elements get included in this calculation and what can be excluded?

Should I base my calculations on plan or elevation?

How do you calculate the existing building structure reuse?

How do exterior elements, such as a covered dock, get counted? Would that be considered a slab or exterior hardscape and not part of the building?

NC-2009 MRc1.1:Building Reuse—Maintain Existing Walls, Floors and Roof

Steel Joists

We have reused and relocated some steel roof joints in an existing building (between additional existing joists to reduce the spans in an area). We are not pursuing MRc3 as we do not foresee having 5% of the material costs. As we are relocating but still within the existing building, can this contribute to MRc1.1 if we require? Otherwise, my understanding is that we can use them to contribute to MRc2. Thank you.

MT, this would contribute to MRc2, but not MRc1.

For clarification, why would this not contribute to MRc1.1? As per MRc3 Bird's Eye View, MRc1: Building Reuse can involve preserving part of a building or a material onsite and reusing it for its original purpose, or leaving it in its original location. The preserved portion of the building, or the material, only counts toward MRc1: Building Reuse (but not toward MRc3: Material Reuse or MRc2: Construction Waste Management). The joists are being 'reused for its original purpose'. There are other walls, floors, etc. that are in their original location that are being reused and can contribute to this credit. Thank you for the clarification.

I think that is OK, actually. We know that MRc3 materials must be given a new purpose but reusing joists as joists meets the intent of MRc1, in my mind. And when you consider the documentation that would be submitted for this credit, we provide a spreadsheet of building components that are reused so the fact that they are moved first would not be relevant. Does that make sense?
