In the past few years, advanced-technology tools, such as simulations, have increasingly been used to address logistical barriers, schedule constraints, environmental factors, and risk in support of the design and engineering in many projects. Tools that specialize in modeling physical environments and conditions are particularly useful for many complex projects (e.g., plants and infrastructure)

The model showed that CFD results for the loads on the caissons agreed very well with experiment-scale model data from tests carried out at HR Wallingford in the United Kingdom. Using CFD modeling, the designers of the bridge caissons were able to assess risk and gain confidence in design margin, particularly for the "untested" west pier.

State-of-the-art multiphase modeling techniques were used to prove out the basic design for fluidics mixing in the various process vessels. These models include the transient effects of solid-liquid mixing, such as accumulation, non-Newtonian yielding, air sparging, and heat transfer (Figure 2)

The layer of contaminated topsoil will be removed before construction begins to minimize radiation exposure to workers and schedule risk. For rapid prototyping, the project team used state-of-the-art computer 3-D animation and virtual reality (VR)

ACKNOWLEDGMENTS I would like to acknowledge the outstanding work of the engineers responsible for the projects discussed in this paper, including Brigette Rosendall, Kristian Debus, Carl Johnson, Chris Barringer, Martin Melin, and Feng Wen. They, along with their peers in the Advanced Simulation and Analysis Group at Bechtel, continuously strive to achieve success on challenging, schedule-driven assignments.
