As the first fully automated container terminal in the United States, LBCT sets an example of how shipping facilities can increase terminal efficiency while utilizing zero emissions technology. The BXB utilizes LBCT’s Battery Exchange System to provide automated battery charging and exchanges of Automated Guided Vehicle batteries. This project is a key component of the automatic characteristics and zero emissions goals of MHT by reducing air pollution emissions from cargo movement for the residents of San Pedro Bay.
PACE Advanced Water Engineering served as the engineer-of-record and part of the PERC Water Team under the Kiewit Design-Build-Operate Team to design the AWTF, a contribution to the City of Santa Monica’s Sustainable Water Infrastructure Project (SWIP). The new 1.0 MGD AWTF treats a mixture of raw wastewater from the City’s sewer collection system, as well as stormwater harvested from the City’s stormwater drainage system for groundwater augmentation via direct injection. This alternative source of water diversifies and increases the resiliency of the City’s water supply portfolio by reducing its dependency on imported water.
Walter P Moore for the YouTube Theater project. The YouTube Theater is an intricate element of Hollywood Park, a 300-acre mixed-use development in Inglewood, CA, being developed by Los Angeles Rams Owner/Chairman E. Stanley Kroenke. In its inaugural year, the venue hosted nearly 100 events and over 300,000 fans with acts such as Alicia Keys, Eddie Vedder and the Earthlings, Sebastián Yatra, Aespa, and Jon Pardi. YouTube Theater is one of three venues—including American Airlines Plaza and SoFi Stadium—under a single ETFE roof canopy. During the construction of YouTube Theater, the project team overcame a myriad of challenges, including building the venue near a fault line and directly below the two primary flight approach paths to Los Angeles International Airport, just three miles away. The venue is not only underneath the same ETFE roof canopy as SoFi Stadium, but it is also integrated with 11 roof canopy columns. This integration was made possible by creative engineering experimentation and non-linear time-history analysis of the integrated structure. In addition to exemplary structural engineering solutions, the venue features advanced technology, as well as patron and artist premium amenities that make it a destination venue.
San Francisco Region Honor Award Projects:
Biggs Cardosa Associates, Inc. for the Warm Springs BART Pedestrian West Access Bridge & Entry Plaza. Biggs Cardosa was contracted by the City of Fremont as the prime consultant to provide engineering design for this project, which extends above rail lines to connect the new Warm Springs BART station to the city’s Innovation District, a major new employment center and residential area. The bridge navigates a highly constrained site and consists of two sections, a truss span and a cable-stayed bridge, in order to offer the iconic look of a cable-stayed bridge while avoiding high voltage power lines directly overhead. Biggs Cardosa solved multiple seismic stability challenges posed by the two-section bridge and developed a highly detailed construction staging plan that allowed for partial fabrication of the bridges in the shop and assembly of the truss bridge in the field, enabling contractors to lift the truss from the assembly location over rail tracks and raise the truss to the right elevation, all while maintaining a safe clearance to the high voltage lines just overhead and the BART station immediately adjacent..
BKF Engineers for the Bayfront Expressway Pedestrian & Bicycle Overcrossing in Menlo Park.
