Project Highlights

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.

LAX/Crenshaw Transit Project, California – Analyzed delays during design of a $1.27B 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.

Medicine Specialty Clinics, Pennsylvania – Analyzed delays, loss of productivity, outstanding contract modification requests, outstanding RFIs, and a termination for default on a $4.8M hospital renovation. When the termination for default was issued, the project was over 800 days behind schedule. The Government alleged subcontractor non-payment resulted in a lack of manpower on site. The contractor alleged the delay was caused by contract modifications, owner phased moving delays, unanswered RFIs, and a loss of productivity due to restricted hours. As a result of the alleged issues, the contractor suspended work and submitted claims totaling $1.4M. Prepared a CPM schedule analysis and presented findings to counsel. Assisted counsel with development of deposition questions. Ultimately the contractor withdrew its complaint in its entirety.

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.
