COMMUNICATING THROUGH VISUALIZATION
Visualizing what future development will look like is a key use of 3D models
of the built environment. The city of Sydney, Australia, retained AAMHatch
to develop an accurate 3D model of the city to support analysis of proposed
development projects within the context of their surroundings. Encompassing
20,000 buildings, the sheer scope and complexity of the task called for
nonstandard tools that would simplify data capture.
AAMHatch developed specialized applications to achieve this using
MicroStation MDL. The resulting AAMHatch toolkit simplified the placement
of complex roof structures and construction of nonstandard buildings in the
finished product. The MDL tools accelerated 3D model production by a factor
of 60, and structures that would have taken 15 minutes to build can now be
constructed in 15 seconds.

I- 94 Modified Arch Bridge
Taylor, Michigan, United States
The I- 94 Tied Arch Bridge was an initiative of the Detroit Regional Gateway
Advisory Council to revitalize Detroit’s economy and enhance the I- 94 corridor.
Completed in time for Super Bowl XL, the $14 million bridge is a gateway to the
city from the Detroit, Mich., metro airport. The 72-foot wide structure will allow
a future fourth lane to be constructed with minimal impact to traffic.
Design of the modified arch was achieved using MicroStation’s native 3D and
rendering capabilities to visualize a variety of options. As the idea of oval-shaped braces resembling footballs emerged, the concept of an aerial view
resembling a football with laces also took shape. Constant communications
between the aesthetics team and technical engineers was critical to
overcoming various obstacles and proving the efficacy of the design.
