Selected Project Experience
  • Claim analysis for adverse geological conditions during the construction of river diversion tunnels in a $4.2 billion World Bank financed multipurpose dam construction project.

  • Delay analysis on TBM tunneling in a $1.5 billion World Bank financed international water diversion project.

  • Project management and dispute resolution to complete a $50 million power generation facility in Virginia.

  • Project scheduling in a $30 million public facility project.

  • Project scheduling and delay analysis for differing site conditions on a power generation construction project in Japan.

  • Damage repair cost estimating due to construction defects and water intrusion on multi-story hotels.

  • CPM delay analysis and measured mile study to rebut a $18 million claim in a light rail project.

  • CPM delay analysis in a $80 million wastewater treatment plant upgrade project.

  • Analysis on loss of productivity in several commercial building construction projects using the measured mile method.

  • Engineering productivity impact analysis for a $300 million chemical process plant project in the Middle East as the result of numerous owner changes and directives to the design build contractor’s design that resulted in cumulative impact to contractor’s engineering productivity and schedule.

  • Cost analysis and schedule analysis to help the client reach a settlement through mediation on a claim of about $200 million associated with a delay of about a year in a $1.1 billion rail construction project.

  • Forensic engineering analysis and expert testimony for a slope failure during the construction of a commercial facility.
