Issues included high rainfall experienced in the tropical climate, soil compaction, and resulting delays and impacts. He conducted a critical path method (CPM) schedule analysis, developed an as-built schedule, and evaluated contractor lost labor productivity damages using measured mile methodology. Mark testified as an expert witness concerning the lost labor productivity analysis claims and alternate measured mile in the U.S. Court of Federal Claims.

U.S. Coast Guard Deepwater Program – Assisted the contracting, legal, and program teams for the U.S. Coast Guard in evaluating a request for equitable adjustments (REA) and program areas of concern. For the national security cutter project, he reviewed the contractor’s $300 million REA for technical entitlement and quantum, and he established a document database for tracking key program and issue documents. For the 123-foot patrol boat project, he participated in the collection, analysis, and evaluation of government and subpoenaed documents along with electronically sourced information (ESI) records.
