BMO Stadium

OVERVIEW
Langan provided multidiscipline engineering services in support of the design and construction of a new stadium for the Major League Soccer's Los Angeles Football Club. The 22,000-seat stadium and ancillary structure are being built on a 75-acre site adjacent to the landmark Los Angeles Memorial Coliseum and Exposition Park. During planning and entitlements, Langan performed a hydrology study, developed a preliminary grading plan, provided a utility supply assessment in support of an Environmental Impact Report Addendum, and completed a preliminary geotechnical investigation. During the design phase, we performed a supplemental geotechnical investigation and provided Deputy Grading observation through construction.

Los Angeles Chargers Training Facility

OVERVIEW
Langan provided multi-discipline engineering services in support of the new Los Angeles Chargers NFL training facility and team headquarters in Costa Mesa, California. The project site is a 5-acre redevelopment parcel that required tenant and parking improvements and the construction of new practice fields. As part of the design phase, Langan provided grading and utilities design, land surveying, Storm Water Pollution Prevention Plan (SWPPP), and SWPPP monitoring/inspection. Geotechnical services included materials testing, observation and testing earthwork, subgrades for shallow foundations and concrete flatwork, and foundations for fence light standards at the practice fields.

UCLA Center for Health Sciences

OVERVIEW
Langan developed site-specific response spectra and time histories for the University of California, Los Angeles Center (UCLA) for Health Sciences. We performed probabilistic seismic hazard analysis (PSHA) and deterministic analysis to develop smooth, site-specific horizontal spectra for two levels of shaking corresponding to the Design Basis Earthquake (DBE) and Maximum Considered Earthquake (MCE).
