INNOVATION IN STRUCTURAL ENGINEERING
The 112-story Lotte Super Tower proposed for Seoul, South Korea, is a
550-meter-tall, mixed-use building with a steel diagrid structural system. The
exterior structural diagrid has 68 unique (432 total) joints at which six major
members come together at a single point. Morphing from a square base to a
circular top, the building geometry posed a technical challenge for the structural
engineering team.
The team developed custom tools to manage the diagrid connection geometry,
enabling it to create accurate physical and analytical 3D models of the
structure. MicroStation and Bentley structural software provided the main
interface to the custom application used to parametrically describe and manage
the node connections. The 3D model supported creation of 2D and 3D drawings
and the provision of accurate digital information to the steel supplier/fabricator.

Cougar Dam and Reservoir Adult Fish Collection Facility
Blue River, Oregon, United States
Located on the South Fork of the McKenzie River near Blue River, Ore., the
Cougar Adult Fish Collection Facility will assist in a collecting, sorting, and
transporting program to connect fish populations located upstream and
downstream of Cougar Dam. The $14.7 million facility includes a fish ladder,
pre-sort pool, sorting facility, and two pump structures for water supply.
MicroStation, Project Wise, and S TAAD enabled a shared model approach that
allowed for structural, mechanical, electrical, hydraulic, civil, and geotechnical
engineers to effectively integrate the design. Challenges were addressed by
fostering collaboration among the design team members to maximize product
reviews and ensure effective communication.
