diagrid steel shell of the new ARTIC terminal building

The grand opening for the Anaheim Regional Transportation Intermodal Center (ARTIC) was held on Saturday December 13, 2014. The 67,000 square foot iconic transportation hub increases mobility options for residents, local businesses, commuters, and visitors to Anaheim, Orange County, and the entire Southern California region. The building reaching 117-feet high is housed in a a diagrid steel shell structure (pictured above) and features the largest ETFE (Ethylene Tetra Fluoro Ethylene) roof expanse in North America.

Group Delta
provided construction materials testing and inspection services during the construction of ARTIC. Some of the testing and inspections we provided included: rebar, concrete, forms, fireproofing, shop steel inspection, steel ultra-sonic testing, welding/bolting/field inspections, building inspection/MEP/HVAC.

In January 2014, the California Geologic Survey released an updated preliminary review map of earthquake fault zones in the Hollywood Quadrangle. The map shows estimated traces of the Hollywood Fault running through downtown Hollywood. In the video below, Group Delta CEO Michael Reader discusses the trench investigations conducted at four sites where the fault was thought to exist.

The map, when finalized, will define a new earthquake hazard zone in Hollywood and would require most new construction projects within this zone to conduct a fault rupture investigation prior to construction permits being issued. Group Delta has a team of expert geologists and paleoseismologists who have decades of experience in locating faults within Alquist-Priolo Zones. See our page on fault investigations for more details.
