FIDIC / Legal Reference: FIDIC Red Book Clause 13.6
A method of valuing Variation work based on the actual time spent by the contractor’s labour and plant, plus materials used, at rates set out in a Daywork Schedule. Daywork applies where the nature of the work makes it impossible or impracticable to value the Variation using BOQ rates or agreed lump sums.
What it means in practice
Under Clause 13.6, the Engineer may instruct that Variation work is to be carried out on a Daywork basis if the work cannot be properly measured and valued by other means. The contractor must submit daily Daywork sheets showing the resources used, signed by the Engineer’s representative on site, within seven days of the work being done.
Daywork rates are typically pre-agreed in the Daywork Schedule annexed to the contract. They normally include all-in labour rates (including overheads and profit), plant hire rates, and a percentage uplift on material costs.
Where disputes arise
Unsigned Daywork sheets are one of the most common final account disputes in UAE construction. The Engineer’s representative may be reluctant to sign sheets without head office approval. Contractors should pursue signatures promptly and treat unsigned sheets as a notice event under Clause 20.
UAE Context
In UAE projects, labour productivity rates and plant hire costs vary significantly. Daywork Schedules should reflect UAE market rates at the time of tender to avoid later disputes over quantum.
