Washington SR520 Bridge Replacement and HOV Draft EIS ch2m hiLL
The Portage Bay and Evergreen Point bridges on SR 520 in
Seattle are at the end of their useful lives and must be replaced.
The Federal highway Administration, Washington State Department of Transportation, and Sound Transit — in cooperation
with 15 resource agencies and local jurisdictions — plan to
replace the existing facilities to provide structures capable
of withstanding wind storms and earthquakes and improve
mobility and access.
As a high-profile project, it was critical to visually simulate the
project accurately. The rendering techniques and visualization
tools provided by MicroStation allowed the visualization of
project components as they were designed without the need
for conversion or repair. With the variety of rendering techniques and visualization tools, the teams could render the
3D models to either make them look photorealistic or
Daniel-Johnson Boulevard Revitalization cima, engineering consultants
The Daniel-Johnson Boulevard is an $8 million revitalization
project that consists of converting the existing eight-lane
divided boulevard into a four-lane divided boulevard including
a bicycle path and dedicated parking. Located in Laval,
Quebec, this project complies with the urban guidelines of
the city to develop the new main downtown area.
The major challenge that Cima faced was quickly producing
3D animations using MicroStation, InRoads, and StormCAD
with a team of experienced AutoCAD users. With the integrated capabilities of MicroStation, the learning curve was
short, communications improved, and Cima was able to deliver
not only the design, but also the 3D animation as scheduled.
Cima’s infrastructure team is now versed on both platforms
and, therefore, is capable of addressing a much broader market.
