There is no ‘one size fits all’ formula to addressing project management. We simply understand and appreciate that every project is unique and should be approached as such. We know that every project requires an independent analysis of potential contributing factors, and some ‘out of the box’ thinking to help clients move forward with confidence.

The 30 Forensic Engineering Construction Claims Group has two main service areas: Construction Claims/Dispute Resolution and Project Advisory

Construction Claims / Dispute Resolution

When disputes or challenges arise on a project, our clients rely on us for independent, forensic analysis of the technical, schedule and cost factors affecting the efficient and effective construction, our knowledge of industry standards of practice, and litigation support services. Our work focuses on identifying the root causes, the allocation of responsibility for changes, delay, acceleration, disruption, extension of time, etc., demonstrating entitlement and quantifying the damages. Our involvement enhances and facilitates our clients’ decision making with regards to dispute resolution options, the negotiation and settlement process, and their financial risk  and exposure.
