Project Overview
Columbia Engineering Group provided structural engineering and steel design for Gateway Substation in Richland, Washington. The project included structural systems for a new electrical substation serving the City of Richland.
The project included modular tapered steel structures designed to support electrical equipment and transmission components. CEG developed A-frames, H-frames, and T-frames as part of the substation structural system.
Structural Design for Utility Infrastructure
Substation structures must resist several types of loading while supporting critical electrical equipment. Therefore, CEG performed structural analysis for wind, seismic, and equipment loads.
The project also required practical fabrication and installation details. As a result, the structural design accounted for connection detailing, base plates, galvanizing, and field installation.
Structural Engineering Scope of Work
CEG provided structural analysis, steel design, connection detailing, and fabrication support for the new electrical substation.
Modular Steel Structures
CEG designed modular tapered steel A-frames, H-frames, and T-frames for the new electrical substation.
Structural Load Analysis
CEG analyzed wind, seismic, and equipment loads in accordance with applicable NESC and ASCE standards.
Connection & Base Plate Design
The structural scope included connection detailing and base plate design for the modular steel support structures.
Fabrication & Installation Support
CEG coordinated the structural details to support efficient fabrication, galvanizing, and field installation.
Project Outcome
Gateway Substation received structural support systems designed for the long-term demands of electrical utility infrastructure serving the City of Richland.
CEG combined standards-based structural analysis with fabrication-ready detailing. As a result, the design supports constructability, efficient installation, durability, and long-term substation performance.
What Made This Project Stand Out
A-frames, H-frames, and T-frames support electrical equipment and transmission components throughout the substation.
CEG evaluated wind, seismic, and equipment loads using applicable utility and structural design standards.
Connection and base plate designs support efficient fabrication, galvanizing, and field installation.
The structural package was coordinated for constructability, durability, and long-term performance of the substation infrastructure.
