About

Construction schedule and cost expert with over 20 years of experience analyzing complex construction projects. I specialize in CPM scheduling, delay and disruption analysis, cost impacts, and construction claims, providing clear, defensible opinions for owners, contractors, and attorneys. My work focuses on bringing clarity to disputed schedules, costs, and responsibility.

I am a construction schedule and cost expert with more than 20 years of experience in construction management, scheduling, cost estimating, and project controls across a wide range of commercial, infrastructure, and specialty construction projects. I hold a Bachelor of Science in Mechanical Engineering and am a licensed Professional Engineer (Civil). My professional background includes hands-on experience with how construction projects are planned, sequenced, executed, and managed in the field, as well as how they are documented, scheduled, and cost-tracked at the project controls level. This combination allows me to evaluate disputed schedules and costs in a practical, real-world context grounded in industry standards and actual construction practice. I regularly provide expert analysis and litigation support on matters involving schedule delays, disruption, cost growth, change orders, and construction defects. My work includes CPM schedule analysis, as-planned versus as-built evaluations, delay and impact assessments, cost impact analysis, and responsibility allocation. I support attorneys through expert report preparation, rebuttal analysis, and deposition and trial preparation, delivering clear, well-supported opinions that can be understood by both technical and non-technical audiences.

Methodology & Approach

My approach to expert witness work is methodical, independent, and grounded in contemporaneous project records. I begin by developing a clear understanding of the project scope, contract requirements, and project timeline, followed by a detailed review of schedules, cost records, correspondence, and supporting documentation. Schedule analyses are performed using CPM-based methods appropriate to the available data and the specific issues in dispute, including as-planned versus as-built comparisons, windowed analyses, and time impact evaluations where applicable. Cost analyses focus on identifying and quantifying cost growth, productivity impacts, and change-related costs, with careful attention to causation and responsibility. Throughout my work, I focus on transparency, repeatability, and defensibility. My goal is to provide opinions that are technically sound, clearly explained, and capable of withstanding scrutiny in deposition, arbitration, or trial.
