Project Highlights

Las Vegas Raiders Stadium, Nevada – Reviewed schedule updates during construction of a new 10-floor $1.8B design-build stadium. Analyzed delays, added costs, and lost productivity to steel fabrication and erection. After the mill order, 14 Tekla model revisions and hundreds of ASIs and RFIs were issued. Analyzed schedule impacts to CPM schedule that failed to set a shop capacity limit for the steel fabricator. Calculated lost productivity to over 28,000 tons of steel fabrication due to utilization of over 20 subfabricators to meet accelerated schedule. Assessed critical path impact of subsequent erection delays to over 20 different critical paths of work. Prepared expert reports on delays and lost productivity.

LAX/Crenshaw Transit Project, California – Analyzed delays during design of a $2.1B metropolitan rail transit system. Completion of design was delayed by over two years due to various issues including misaligned tracks, the addition of a new transit station, a second realignment of tracks to accommodate a new transit station, below grade ventilation and life safety enhancements, various communications design changes, at-grade curb radii and streetscape changes, utility conflicts, and extended design review periods. Prepared a CPM schedule analysis and assisted in preparation of REAs for the delay and damages incurred.

Ghent Station Ash Pipe Conveyor, Kentucky – 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, misfabrication 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 misfabricated truck loading station steel. Prepared a CPM schedule analysis. Assisted in preparation of an expert report. Assisted in preparation of an arbitration presentation which resulted in a full award being granted.

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