Work or responsibility needed for the project that is absent, unclear or inconsistent across the available documents and prices.
Why it matters
Unresolved scope gaps can become variations, disputes or direct margin loss after a fixed price is accepted.
Example in practice
The drawings show a rooflight, but no tender package includes supply, structure or weathering details.
Use the term carefully
State the scope, amount, adjustment method or contract meaning whenever this term could change who carries cost or risk.
