Abstract

Managing 1 Million tons of soil using 3D time-enabled GIS
Track: Architecture, Engineering, and Construction
Authors: Cris Perez, Richard Quateman

The Massachusetts Bay Transportation Authority has brought light rail service to the cities of Somerville and Medford. More than 1 million tons of soil will be excavated. Soil needs to be tracked throughout the construction, for which a 3D model with about 4,000 soil units was built. We used model builder and MS Access to classify the soil units from the original soil boring data. We enabled time to represent excavation schedules, and shared data amongst team via arcgis online.
