A method of valuing work using agreed labour time, materials and plant records when the work cannot be priced reliably in advance.
Why it matters
Daywork needs prompt, signed records; otherwise the time and resources used can become difficult to agree.
Example in practice
The site team records two operatives, four hours and the materials used for an instructed opening-up item.
Use the term carefully
State the scope, amount, adjustment method or contract meaning whenever this term could change who carries cost or risk.
