SoFi Stadium and Entertainment District-Hollywood Park
This session will earn 1.5 PDHs
Abstract: SoFi Stadium is an unprecedented and unparalleled sports and entertainment destination being built in Inglewood, CA. The first indoor-outdoor stadium to be constructed, SoFi Stadium will be the home of the Los Angeles Chargers and Los Angeles Rams when it opens in summer 2020. The state-of-the-art stadium will host a variety of events year round including Super Bowl LVI in 2022, the College Football Championship Game in 2023, and the Opening and Closing Ceremonies of the Olympic Games in 2028. Located on the site of the former Hollywood Park racetrack, the stadium is the centerpiece of a 300-acre mixed-use development featuring retail, commercial office space, a hotel, a performance venue, 2500 residential units, and outdoor park spaces. This $5 Billion project is the largest active development in California.
- The stadium field sits 100 feet below adjoining grade requiring a 100-foot high MSE surrounding the stadium and a complex system of retaining walls for the tunnels and ramps to the field.
- The translucent stadium canopy has a massive system of foundations extending outwardly from the stadium, in some locations extending under the adjacent public roads.
- Utility design included complex 3-D modeling with extensive coordination with the architectural/structural team.
- The project incorporates a lake amenity that doubles as a water quality and stormwater detention facility.
- The complex nature of this project, together with its fast track schedule, multiple prime contractors, designers, and agencies, as well as its sheer size has presented many challenges to the team of engineers and surveyors.
- Innovative structural design of the retaining walls and stadium canopy foundations including the seismic design considerations. The canopy struts extended outwardly from the stadium underneath public streets, thus creating challenging re-rerouting of existing and proposed utilities. Sophisticated 3-D modeling was used to resolve utility and strut conflicts.
- Project workflow techniques that accommodated owner-initiated revisions while maintaining the aggressive project schedule.
- Hydrologic modeling and drainage design that adapted an existing man-made lake to a combination water quality / stormwater detention / project amenity. This helped the project comply with stringent agency standards for stormwater quality and quantity.
