08USC COLISEUM
Legacy project record
USC COLISEUM USC was set out to overhaul the 1923 Los Angeles Memorial Coliseum with a new structure that would include suites, a concourse and a press box. Hathaway Dinwiddie began construction the day after the last Rams game in 2017. The existing stadium seating rested on grade with tunnels that led from the exterior to the field. The extents of the demolition and excavation would be as limited as possible to protect the seating not included in the new structure region. The existing tunnels and past retrofitting would be exposed in the excavation. Historical and retrofit drawings were extensively reviewed and coordinated in the shoring documents. The historical entrance stairs had to be hung off of the shoring, cantilevering out over the excavation. Calex Engineering installed the shoring system and helped to coordinate all the unexpected filed conditions not shown on the as-built drawings.
09WESTFIELD CENTURY CITY
Legacy project record
WESTFIELD CENTURY CITY The Westfield Century City Mall construction team had an approach to the excavation like we had not encountered before. An existing low-rise office building already occupied the site. It already had a 4 level basement. The contractor determined that, while the foundation system for the new mall extension and the below grade parking decks would be completely different than that of the existing building's, it would be cheaper to leave the basement walls in place for reuse. This eliminated the need for conventional steel soldier piles and lagging. A bracing scheme was developed that held back the walls with a tieback on a strongback supporting the wall at the existing decks but out of the way of the proposed decks. The strength of the existing wall was key to the brace layout. Deep utilities and a bridge pier plagued the tieback coordination. On sides where adjacent structures already existed to matching depths, a cantilever pile was used to hold the wall upright while the decks were replaced.
