Definition

A structured document that describes and quantifies work items so contractors can price the same measured scope.

Why it matters

A consistent BOQ makes tender returns easier to compare, but it still needs a clear measurement basis and specification.

Example in practice

A tender BOQ lists 42 m² of external wall insulation and provides a rate and total column for each tenderer.

Use the term carefully

State the scope, amount, adjustment method or contract meaning whenever this term could change who carries cost or risk.
