About Us

A Diverse Team with Construction Claims and Project Management Expertise

Our team of over 50 professionals have extensive domestic and international experience.

We are committed to:

  • Solving complex construction project problems and disputes
  • Paying rigorous attention to details
  • Providing high-quality work products for our clients

Our personnel are experienced with large, complex, grassroots, revitalization, and reconstruction projects incorporating conventional-phased, fast-track, EPCM or EPC turnkey concepts. Prior to establishing their claims consulting careers, our personnel have many years of engineering, construction project management, contract administration, and project controls experience.

We are also experts in retrospective delay analyses on complex engineering and construction projects.  We have evaluated the application of numerous delay analysis methodologies, including those discussed in the North American Society of Construction Law Delay and Disruption Protocol and the AACE® International’s Recommended Practice No. 29R-03 for Forensic Schedule Analysis, and can apply any of the acceptable analytical techniques that would be appropriate for the complexities involving a project.
