Damages detached from the analysis
What supports the period and resource assumptions used in the cost analysis?
General contractors, subcontractors and construction managers

Expert witness
Delay-related cost analysis examines claimed time-related costs and their relationship to construction events and conditions. Sources, assumptions and the scope of the inquiry vary with the project record.
Delay-related cost questions may involve time-related resources, overhead, escalation, acceleration and other categories. Analysts may examine recorded costs, contributing conditions, administrative records and assumptions; schedule and cost work may proceed together or in stages.
Damages analysis may examine attribution, periods, cost categories, assumptions and whether delays were concurrent on the critical path. How concurrent delay is treated depends on the contract and applicable law, which are for counsel and the tribunal. The scope and available information affect which questions can be evaluated.

Possible assignment considerations
Identify the events or periods assumed in the cost analysis and explain their support. Alternative scenarios can be evaluated while time effects remain disputed.
Separate resources incurred because of duration from the cost of performing the work itself.
Set out the basis and assumptions behind any home office overhead element rather than embedding them in a calculation.
Account for costs that would have arisen anyway, that reasonable steps would have avoided, or that the claiming party caused.
Considerations and limitations
What supports the period and resource assumptions used in the cost analysis?
Presenting a formula result without exposing the assumptions underneath it.
Leaving contribution and mitigation to be raised by the other side, which damages the credibility of the whole.
