Abstract

The Los Angeles Metro Rail Subway project is initially planned for 30 km (18 mi) of twin, 6-m (20-ft) diameter bored tunnels under city streets and a total of 16 stations. This paper describes briefly the history of the project, the geologic setting, and the challenges encountered during design or anticipated during construction. It also introduces, as part of contract documentation, an interpretive geotechnical baseline report which establishes the basis for identification and recognition of site condition "baselines". In so doing, this report (known as a "GDSR") has proven to be an effective tool for ameliorating contractual problems and facilitating conflict resolution.

Use of Geotechnical Design Summary Report as a Management Tool for Resolving Disputes on Underground Construction Projects

St. Louis, Missouri

The Los Angeles Metro Rail Subway project is initially planned for 30 km (18 mi) of twin, 6-m (20-ft) diameter bored tunnels under city streets and a total of 16 stations.
