TEN50
TEN50 preserves a current-site project example for a square excavation with tiebacks, utility coordination, corner bracing, and monitoring near an existing brick building.
Project context
Project profile for TEN50, preserving current site content about shoring for the Downtown Los Angeles retail and residential tower.
TEN50, also known as 1050 S. Grand, is a 22-story retail and residential tower in Downtown Los Angeles with three below-grade levels.
The square excavation used two and three rows of tiebacks, allowing shoring installation and excavation to progress quickly. Wet and dry utilities were deep, including a communications vault immediately adjacent to the shoring bulkhead, where corner bracing could be used.
Extensive monitoring during pile installation was used along an existing brick building to help prevent cracking in the older structure.
