Common questions
Is a replacement unit always treated like-for-like?
No. New equipment can change footprint, weight, anchorage, dunnage geometry, and service-clearance assumptions enough to affect the structural package.
Can changed support points affect the filing scope?
Yes. Once the receiving structure or support concept changes, the structural and filing burden often increases.
What should be checked early?
Existing drawings, roof support conditions, old versus new unit data, and whether screens, catwalks, or access details also change.
