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.

Apartment Tower Renovations – Engaged on behalf of cabinet supplier on a $65M 11-story apartment project. The supplier was seeking payment after the construction manager asserted delays and acceleration backcharges and refused to pay.
