More and less work and cost control

The cost control of a plan does not stop with a good tendering of the design to a contractor. In many cases, discussions about additional and less work follow after the agreement has been concluded. Depending on the tender form, additional and fewer works may occur during the design phase or implementation phase.

Assessing extra and less work

In both cases, IGG has experts in assessing extra and less work. In all cases, the following steps must be made transparent in a very transparent manner:

  1. What is actually contractually agreed;
  2. What extra (or less) is required;
  3. What is a realistic price for these extra and less works;
  4. What is actually achieved extra?

The first three points are clearly mapped with the help of open budgets. By comparing the additional and / or less work with the contract documents and the registration budget, it can be determined whether there is actually settlement. IGG approaches suppliers with which the budget is based on real market prices. These documents ultimately form the basis for the discussion with the implementing party with which a well-founded discussion can be held about the extra and less work.

One of the most important points in this assessment is the definition of the principles that were used when making the budget. By comparing the additional and / or reduced work submitted with the specifications and the registration budget, it is possible to determine whether settlement has actually taken place. We take into account agreements made in the contract phase about how the surcharges are settled. 

The IGG experts have extensive experience in assessing more and fewer works. They conduct a discussion for you with the contractors, with which a correct balance is achieved between the costs and the extra work that the contractor carries out for this.
