Rock excavation is paid by unit price, and field quantities exceed the bid quantity. Which record best supports the payment adjustment?
Correct Answer
A) Jointly documented field measurements tied to the unit-price item
Unit-price adjustments depend on measured quantities of the defined work, so documented field measurement supports the payment change. Other choices lack the quantity basis or ignore measured overrun.
Why This Is the Correct Answer
Unit-price adjustments depend on measured quantities of the defined work, so documented field measurement supports the payment change. Other choices lack the quantity basis or ignore measured overrun.
Why the Other Options Are Wrong
Option B: Classify the condition as a lump-sum guess from the superintendent
Choice B gives A lump-sum guess from the superintendent. Its specific error: it answers the Unit-price documentation prompt with the wrong practical move.
Option C: Base the unit-price documentation response on the original bid quantity
Choice C (The original bid quantity only) is rejected because the option delays or omits the controlling step.
Option D: Classify the condition as a photo with no measured quantity
In procurement and contracting, A photo with no measured quantity is the wrong selection for Unit-price documentation: the choice would not get the project to Jointly documented field measurements tied to the unit-price item, which is the Unit-price documentation result verified by the source.
Memory Technique
Pair unit-price documentation with the real field trigger, then choose the response that produces Jointly documented field measurements tied to the unit-price item.
Reference Hint
Open Construction Project Management, 5th Ed. (2022); use the index entry or section for "Unit-price measurement documentation" to confirm that Unit-price adjustments depend on measured quantities of the defined work, so documented field measurement supports the payment change.
