Quantum Analysis, Quantity Surveying Issues & Quantum Expert Reports

Proper and accurate evaluation and costing of construction works causes frequent arguments and disputes amongst quantity surveyors, lawyers and project managers in the construction industry. There are numerous variances within the details of the valuation of variations, prolongation claims, disruption claims, works carried out in changed circumstances and conditions, and changed quantities of work, as well as many other items. For example:

  • whether site and head office overheads should be included and if so at what level;
  • whether contract rates should be used or whether new reasonable rates should be calculated;
  • whether the work was executed under similar conditions to those anticipated at the time of tender and if not, how this affects the payment to be made;
  • the cost elements to be included in prolongation claims;
  • whether prolongation claims should be priced at contract rates or at cost;
  • whether disruption has been incurred and if so, how should it be priced;
  • whether there is any basis for a global claim, etc..

In addition to these examples, numerous other quantum issues arise on a regular basis.

There is a substantial amount of case law and legal precedent that must be followed to ensure the correct basis for valuation is used in each case, and which must accord with prevailing circumstances and the particular form of contract.

Our clients and their legal advisors find our opinions on valuation of claims, variations and other matters to be very beneficial in establishing the real value of the dispute, as well as strengths and weaknesses in the quantum of the case. This can be fundamental in determining strategy and deciding whether to settle or pursue the case.
