Abstract
The following case history presents innovative geotechnical solutions which allowed the simultaneous construction of two overlapping projects, by two different contractors, sponsored by different governmental agencies under tight project schedules. A settlement sensitive Light Rail Transit (LRT) line was to cohabitate the same alignment as a new freeway with embankment heights of 27 feet; both of which are on compressible and weak subgrade soils. Construction activities could not impinge on one or anothers project. The geotechnical concepts used allowed the two projects to proceed simultaneously and minimized the impacts of embankment induced settlement on the two LRT tracks. Field monitoring confirmed the expected soil movements were not greater than the tolerable limits for either project.

Geotechnology Allows Construction of Two Cohabirating Projects
St. Louis, Missouri
The following case history presents innovative geotechnical solutions which allowed the simultaneous construction of two overlapping projects, by two different contractors, sponsored by different governmental agencies under tight project schedules. A settlement sensitive Light Rail Transit (LRT) line was to cohabitate the same alignment as a new freeway with embankment heights of 27 feet; both of which are on compressible and weak subgrade soils. Construction activities could not impinge on one or anothers project. The geotechnical concepts used allowed the two projects to proceed simultaneously and minimized the impacts of embankment induced settlement on the two LRT tracks. Field monitoring confirmed the expected soil movements were not greater than the tolerable limits for either project.
