Need some help evaluating whether my project is a repair, addition, or alteration, a combination of the three.
1. We are renovating an existing pre-engineered metal building to add a new elevator shaft (either steel framing or CMU). Would this be considered as an "addition" or an "alteration"?
I am tracking it as an addition, since we are increasing the floor area. However, other engineers in my group worry that by adding the shaft, we are changing the as-built structure, and of course the structure is seeing more loads, including wind, as well. They feel it should be classified as an "alteration".
What do you think?
2. All exterior wall and roof panels will be replaced. The wall panels will be replaced 1:1. The roof panels will also be replaced, but with a panel + insulation that slightly increases the dead load (I am tracking it increases it more than 5%).
The existing panels have some corrosion. There is some water intrusion, and wear and tear. I am tracking this effort as a repair per the IEBC definition.
Agree or disagree?
3. So lets say I am correct, and #2 is a repair and #1 is an addition. Are the requirements for repairs, additions, and alterations to be treated separately? For example, treat the panel replacement as a repair, and that scope is subject to repair requirements, and the elevator shaft is an addition subjected to "addition" requirements?
Or, since the elevator shaft is an addition and those requirements govern, the whole project must now be subjected to the requirements of "addition"?
4. Can someone help me understand the requirements for additions? Obviously the elevator shaft can be designed for the latest and greatest IBC criteria, but what about for the existing structure? How far do I have to follow the loads to ensure the existing structure is okay? Do I use the latest and greatest codes for the elevator shaft and the original as-built code for the existing structure evaluation, or does the new building code criteria govern for both?
