Steps
Identify the structure's function: a temporary elevated platform supporting employees or materials is a scaffold under Subpart L; a structure supporting freshly placed or curing concrete formwork is shoring/formwork under Subpart Q
Check whether the crew erecting it is functioning as scaffold erectors or as concrete-formwork/shoring erectors, since OSHA has treated these as distinct trades with distinct standards applying
Confirm which competent-person designation and inspection regime applies, the Subpart L scaffold competent person versus Subpart Q formwork/shoring requirements
Where a structure serves a dual purpose, such as shoring later reused as a working platform, apply the standard matching its actual current use, not its original purpose
When in doubt, consult OSHA standard interpretation letters addressing the specific configuration, since this boundary has been the subject of formal OSHA guidance
Known gotchas
The same physical components, such as frames, jacks, or tube-and-coupler hardware, can be either scaffolding or shoring depending on function — the applicable standard follows the use, not the hardware
Shoring/formwork erectors are not automatically covered by scaffold-specific requirements such as the 1926.451 competent-person inspection rules — don't assume Subpart L applies just because scaffold-like components are involved
