The drawing calls for copper piping while the signed scope lists PEX, and neither document establishes priority. What should happen before installation?
- ABuild both versions for free
- BChoose the cheapest interpretation silently
- Obtain written contract clarification
- DDestroy the conflicting document
Why C is correct
The best answer is: Obtain written contract clarification. Early written clarification assigns design intent, cost, and time and preserves a record. Silent assumptions can cause nonconforming work and disputes over changes. The new fact pattern changes the setting, not the governing rule or management control. The other choices either skip a required step, apply a different rule, or fail to address the stated risk.
