Construction Delay Claims
CPM Scheduling Expert

Construction delay claims and construction defect claims comprise the majority of construction litigation, both of which are often complex and challenging to measure, particularly without expert insight.

VERTEX’s team of Critical Path Method (CPM) scheduling experts evaluate and construct delay claims and time extension requests for clients across the construction industry on all types of projects.

Our construction delay experts employ a range of industry-recognized forensic scheduling techniques. Selecting the right delay analysis method requires assessing individual claim characteristics and project specifics. Key criteria, such as the availability of contemporaneous schedule updates, requirements of the contract documents, and the quality and/or the reliability of available construction schedules can play a role in deciding which methodology is appropriate for your situation.
