Project Highlights
NFL Stadium – Reviewed schedule updates during the construction of a new 10-floor $1.8B design-build stadium. Analyzed delays, added costs, and lost productivity to steel fabrication and erection. Project included over 28,000 tons of steel fabrication.

Subway Expansion Project – Prepared schedule updates during the construction of a $208 million transit station. Analyzed delays, inefficiencies, and constructive acceleration encountered throughout construction. Two years into the project, the owner revised over 650 contract drawings without providing a time extension. Analyzed the impact of $45M in change orders which included switchgear and permanent power revisions, elevated slab electrical grid revisions while concrete pours were in progress, axial fan variable frequency drive changes and re-procurement during acceptance testing, additional cooling at communication rooms, and escalator power revisions. Prepared a CPM delay analysis to each of the 19 project milestones, all of which were subject to liquidated damages.

Luxury High Rise Condominium Complex – Analyzed delays, inefficiencies, and constructive acceleration during the construction of a $100 million housing complex. Evaluated the impact of design revisions during construction to concrete superstructure, curtainwall, MEP piping and equipment, and individual unit/condo customizations. Prepared a CPM analysis for overall building completion as well as the completion of each individual unit/condo. Calculated labor productivity losses due to inefficiencies and constructive acceleration. Prepared mediation presentation. Attended mediation. Prepared expert report.

Coal Combustion Residue Waste Conveying System – Analyzed delays and added costs during fabrication and construction of a one-and-a-half mile long pipe conveyor that carried ash to a truck loading station. Evaluated the impacts of the late issuance of design and shop drawings, late truck loading station steel deliveries, mis-fabrication of all truck loading station steel and its return to the manufacturer for repairs, redelivery of truck loading station steel, and the subsequent on-site repairs of the redelivered steel. Compared truck loading station construction delays to delays in construction of the pipe conveyor to determine compensable and concurrent delays. Evaluated contractor’s work orders and cost report to determine added costs resulting from the mis-fabricated truck loading station steel. Prepared a CPM schedule analysis. Assisted in preparation of an expert report. Assisted in the preparation of an arbitration presentation which resulted in a full award being granted.

Children’s Hospital – Analyzed $10 million in claims by the Mechanical & Plumbing contractor on a five-story 250,000 square foot hospital. The contractor alleged added scope due to BIM coordination, loss of productivity, and various unpaid change orders. Evaluated the validity of loss of productivity and air handling unit redesign costs. Assisted in the preparation of an expert report and a mediation presentation.
