The drywall lead verifies a control-joint layout: a cheaper product differs from the specified basis and has not been approved. What should happen before purchase?
Correct Answer
C) Submit it through the substitution procedure and wait for approval
Submit it through the substitution procedure and wait for approval is the contract-appropriate response: the distractors either bypass required review, conceal a defect, or create a payment or quality dispute in scenario item 396.
Why This Is the Correct Answer
Submit it through the substitution procedure and wait for approval is the contract-appropriate response
Why the Other Options Are Wrong
Option A: The contractor should install first; without required owner or contract approval
The trap in A is Install first; without required owner or contract approval. That selection is wrong because it leaves the work at an informal or incomplete stage, while Substitution requires.
Option B: Base the substitution response on mark it as an RFI only
Choice B gives Mark it as an RFI only. Its specific error: the option delays or omits the controlling step.
Option D: Close contract execution first and resolve the substitution record later
In procurement and contracting, Delete the product is the wrong selection for Substitution: it removes the controlling Substitution requirement instead of meeting it.
Memory Technique
Remember substitution by its jobsite consequence: the correct move points to Submit it through the substitution procedure and wait for approval.
