A curved and leaning wall
Along Gridline RA, the west wall of the east classroom wing curved continuously while leaning inward at an increasing angle. This required precise three-dimensional definition of the changing framing geometry.

Project overview
Structural steel detailing for one of Washington's largest high schools.
Eisenhower High School in Yakima, Washington, is a large educational facility comprising approximately 333,000 square feet across nine principal building areas.
The school includes two major classroom wings, a performing arts theater with an overhead catwalk, a full gymnasium and two elevated pedestrian bridges connecting the wings.
Working for Allied Steel, Anatomic provided detailing for approximately 2,100 tons of structural steel. The scope combined complex architectural geometry, specialized seismic bracing and extensive coordination throughout a continually evolving design.

SCOPE OF WORK
A theater, gymnasium, classroom wings and connecting bridges.
The steel detailing package covered nine principal building areas, including:
- A performing arts theater with an overhead catwalk.
- A full gymnasium and associated long-span framing.
- Two large classroom wings extending south from the main building.
- A Level 2 north pedestrian bridge connecting the wings.
- A multilevel south pedestrian bridge.
- Extensive seismic framing, including heavy Yield Line braces.
The different structural systems required coordinated detailing across the building’s interconnected areas.
Model to field
From coordinated geometry to the project on site.
Detailed Model
Built StructureTECHNICAL COMPLEXITY
An evolving design generating hundreds of RFIs.
Specialized seismic framing
A high concentration of heavy Yield Line seismic braces introduced complex connection and coordination conditions throughout the structure.
Incomplete and evolving design
Unresolved design conditions, conflicts and missing information generated hundreds of RFIs, while frequent revision bulletins required continuous updates to the detailing model.
Model-based information control
Tekla User-Defined Attributes linked RFIs, extra-work claims, held steel and submittal status to affected steel components, helping the team manage changes across the project.
OUR APPROACH
One model connecting geometry, revisions and project decisions.
Model-based coordination and tracking
Anatomic used Tekla Structures to coordinate with other trades and manage project information directly within the steel model. User-Defined Attributes helped track outstanding RFIs, held material, extra work and drawing submittals against the affected components.
Connection macros and custom components
Tekla connection macros and custom components reduced repetitive modeling work and supported consistency as connection conditions evolved.
Weekly live model reviews
Anatomic hosted weekly online RFI and model-review meetings with the general contractor, design team and fabricator. Reviewing the live Tekla model allowed participants to examine design conflicts in 3D, clarify difficult conditions and work toward timely resolutions.
