4D Imaging Project Receives Award from
American Society of Civil Engineers
 The American Society of Civil Engineers awarded the GOLDEN GATE BRIDGE SEISMIC RETROFIT PROJECT the Outstanding Civil Engineering Achievement Award for 2007. 4D Imaging founder and CEO, Dr. Glen Stevick and his longstanding colleague, Dr. Weili Cheng designed the seismic dampers for this historic project, determining the seismic energy for the majestic bridge's retrofit. Congratulations!

The War on Lead has been Won!
Billions of dollars have been wasted on a problem that simply does not exist. The Lead issue is a country wide success story and not a toxic threat. This has come to light in a thorough literature review. MORE

Marine Crude Oil Transfer Breakaway
Hawaii Single Point Mooring Terminal
 On May 19, 2006 at 23.20 hours, a Gall Thomson Marine Breakaway connector (GTC) in a floating hose released unexpectedly during the offloading of the ship Front Sundra at the Tesoro Hawaii single point mooring (SPM), causing an oil spill. The 4D Imaging team's analysis indicated a combination of three causes.

Portable Plastic Gasoline Container Explosions
And
Their Prevention
Glen Stevick, Ph.D., P.E., David Rondinone, Ph.D., P.E., Allan Sagle, Ph.D. of 4D Imaging, Inc. and Joseph Zicherman, Ph.D. of Fire Cause Analysis.
Abstract
The work described in this report was undertaken to determine probable causes of reports of portable plastic gasoline container explosions and to consider and demonstrate preventive technologies for such explosions. Dozens of explosions with this class of containers have been reported in newspapers, and are considered in legal briefs and as well as fire incidence and peer reviewed engineering literature. MORE
