Project Name: Mission Utilities
Location: San Francisco, California
Owner: Mission Bay Development Group
Contractor: Alta Engineering
Completed: January 2013
GMI was contracted to re-level 200+/- feet of a settled 48” RCP storm drain line along with re-leveling of two manholes using compaction grouting methods. What made this project complicated was the fact that the pipeline was constructed in Bay Mud and that special care had to be taken in order to preserve all other active utilities along with the active roadway. The pipeline was successfully lifted back to its original grade and the line passed a vacuum test performed by the City of San Francisco. GMI was the only contractor to originally provide a lump sum cost on this project.
