Dayworks
A method of valuing work by recording actual labour, plant and materials at agreed rates, used when work cannot be sensibly measured or priced from the bill of quantities — typically small, awkward or unforeseeable variations.
Dayworks are valued on inputs rather than outputs, which is exactly why employers resist them: there is no incentive to be efficient, and the cost is whatever the time sheets say it is.
Which makes the daywork sheet the entire control. It has to be signed at the time, by someone with authority, recording who was there and for how long — because an unsigned daywork sheet submitted at the end of the month is an assertion, and it will be treated as one. The evidence must be created contemporaneously or the entitlement, however real, is unrecoverable.
