Topic Background   

When contractors encounter owner caused (excusable/compensable) delay, they are typically entitled under the contract to recover both the time resulting from the delay as well as delay damages. Idled equipment/labor and material escalation costs are easily calculated in such situations. Typically, contractors also seek to recover their delay costs (extended field office overhead, general conditions, or jobsite overhead costs) also.  Calculating this cost is more complex than dealing with delayed direct costs. There are, at least, eight methods of calculating extended field office overhead costs. None of the calculations arrive at the same daily delay cost. This webinar discusses all eight methods – offering commentary on the strong and weak points of each. The paper also offers recommendations on how project owners can resolve this dilemma in advance of delays, thus making the issue less contentious should a contractor encounter an owner caused delay.
