A document or set of notes that defines required materials, products, workmanship, standards and performance.
Why it matters
Drawings show where work goes; specifications often define the quality and performance that must be priced.
Example in practice
The specification requires a particular acoustic rating that affects the partition build-up and cost.
Use the term carefully
State the scope, amount, adjustment method or contract meaning whenever this term could change who carries cost or risk.
