ARTIC AWARDED PROJECT OF THE YEAR!

ARTIC is Project of the Year

The Anaheim Regional Transportation Intermodal Center (ARTIC) project was selected as the Project of the Year (2014) by the Orange County Branch of the American Society of Civil Engineers (ASCE). 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. ARTIC is the first LEED Platinum Certified transit station in the world.

Group Delta

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.

I-405 IMPROVEMENT PROJECT UNDERWAY

I-405 Improvements

The Orange County Transportation Authority (OCTA) teamed up with The California Department of Transportation (Caltrans) for the San Diego Freeway (I-405). Currently, the San Diego Freeway (I-405) between State Route 73 (SR-73) and Interstate 605 (I-605) is in its initial stages of the widening process. This project will improve travel conditions for work, commerce, school, and recreation by improving traffic and interchange operations, increasing freeway capacity, and enhancing road safety to meet state and federal standards. The San Diego I-405 Improvement Project will be partially funded by Measure M (Orange County's half-cent sales tax) for this transportation improvements.

Group Delta consucted an aerially deposited lead (ADL) study in areas where near surface soil will be disturbed. Each bridge proposed to be reconstructed will be analyzed for the presence of asbestos containing material and lead based paint. Groundwater at the existing bridges located near potential recognized environmental concerns will be evaluated for any possible groundwater contamination.

In addition, Group Delta is providing preliminary geotechnical recommendations for foundation design, liquefaction potential, maximum credible seismic events and PBA, ARS curves, design level geotechnical investigations, and reports of subsurface conditions for this segment of the I-405 and its bridges.

In November 2014, the California Geologic Survey released the finalmap 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 we conducted at four sites where the fault was thought to exist.

The map defines a new earthquake hazard zone in Hollywood that requires 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.
