Project Highlights

PennDOT, Highway Widening and Reconstruction, Malvern, Pennsylvania – Mark assisted the contractor in preparing a time extension request due to unforeseen subsurface obstructions. The project, which entailed removal and replacement of bridges and abutments, required significant additional compaction grouting due to subsurface limestone voids. Mark helped justify the request by evaluating the planned production vis-à-vis the actual production and inserting a fragnet into the schedule update.

CityStars Development, Cairo, Egypt – On behalf of a developer, Mark analyzed a $170 million delay and disruption claim in Egypt. The project comprised 29 building blocks, including a commercial podium structure, hotels, office buildings, and high-rise apartments. Mark researched the issues, reviewed  schedule updates, and evaluated delay claims for multiple building blocks. He critiqued the contractor’s methodology using the Society of Construction Law Delay and Disruption Protocol and assisted in developing the expert report of findings, which was submitted in international arbitration.

Christiana Hospital, Wilmington, Delaware – This project included a nine-story 286,000-square-foot addition valued at approximately $155 million. Unforeseen rock obstructions during utility installation delayed the project nearly 10 months. Mark assisted the construction manager in negotiating and closing out 10 different delay change orders with a total value over $3 million. He also assisted the construction manager in negotiating a $3.5 million disruption claim brought by the electrical subcontractor.
