Digital Monitoring of a Distressed Building
During the 1994 winter months, portions of a large warehouse roof in eastern Pennsylvania experienced a series of collapses while loaded with snow. Although no occupants were injured, the building was evacuated due to safety concerns. Structural investigations by various parties revealed defective roof member components throughout the facility. After the roof snow load had dissipated, the Contractor for the original warehouse construction rebuilt collapsed roof areas and made certain repairs to strengthen roof members throughout the facility. A disagreement arose between the Owner and Contractor during the repair work pertaining to the scope of roof member component repairs that were necessary to satisfy building code strength requirements. The Contractor completed the strengthening repair work they considered necessary, and the Owner reoccupied the facility. The Owner's structural engineering consultant judged that the partially repaired roof structure was capable of supporting roof snow loads, but with safety factors that are less than those dictated by the building code. Confronted with the onset of the 1995 winter season, the Owner elected to install a computer controlled roof structure monitoring system. The system allows the roof snow loads on the thirty acre roof to be constantly monitored by the building staff and remotely by the Owner's corporate management and consultants. The roof monitoring system has allowed the owner to maintain occupancy of the building in all seasons without having to incur the substantial cost of a roof repair in advance of concluding the dispute.
