Construction Estimating, Including Groundworks and Civils

A good estimate shows how every rate was built, so you can check it, defend it and use it again once you win the work. Decode QS prepares estimates that your team can follow line by line.

Who this service is for

  • Main contractors who need a package priced or a second estimator during a tender.
  • Groundworks and civils contractors pricing drainage, earthworks, concrete and external works. Typical work types include groundworks, drainage, roads and external works.
  • Specialist subcontractors who need a clear take-off and a rate build-up behind their quote.
  • Developers who want a check estimate against a contractor’s price.

What we deliver

  • Bills of quantities from our offshore High Value Centre, prepared to a high standard at lower than UK average cost (see Bills of Quantities)
  • Quantity take-off from drawings and models, measured to the method you require
  • First-principles rates for labour, plant, materials and subcontract, drawn from our proprietary database of current market rates
  • Allowances for preliminaries, temporary works, risk and overheads, all clearly shown
  • A list of assumptions, exclusions and clarifications for your tender submission
  • An editable estimate file and a short summary for sign-off

Groundworks and civils estimating

Groundworks and civils prices depend on outputs, plant choice, ground conditions and how muck and water are handled. We set out the method behind each rate – for example the excavator size, the output per day and the haulage assumption – so you can test it against how you would really build the job.

How it works
