About this Seminar:
Unabsorbed Head Office Overheads can be one of the easiest heads of claims to quantify, but it is also the most difficult to prove. Proving an Unabsorbed Head Office Overheads claim requires the demonstration of a loss. Unlike many other heads of claims associated with delay, it is a loss to the Contractor’s business as a whole, not just a specific project. As a result, the irony is that smaller Contractors are more likely to be able to demonstrate a loss, whereas larger Contractor’s may struggle. This seminar looks at the nature of Unabsorbed Head Office Overheads, the relationship to Loss of Profit Claims, what is required to prove the loss and how to quantify the loss and how this may be done. The various formulaic approaches are looked at and compared along with several variations to the usual list of formulae. Issues with the individual formulae will be examined and discussed.
