TEN50 (1050 S. GRAND)
Design Architect HansonLA and Executive Architect Adamson put the first drone landing pad on this building in Downtown. The 22 story retail and residential Ten50 tower has 3 below grade levels. The square pit was simple for Cefali to shore. With 2 and 3 rows of tiebacks, the shoring installation and excavation progressed quickly. Wet and dry utilities were deep, especially a communications vault immediately adjacent to the shoring bulkhead. Luckily, corner-bracing could be used here. Extensive monitoring during pile installation was used along an existing brick building to aid the contractor in preventing cracking in the old structure.
