AT-PAC SCALING NEW DIMENSIONS: THE ART OF DESIGNING A COMPLEX SCAFFOLD FOR A CONE-SHAPED SILO

May 18, 2023

The AT-PAC design team recently took part in an exciting scaffolding engineer design project for the Omaha Public Power District (OPPD) in Omaha, Nebraska. This project involved a complex scaffolding design requirement in order for our client to perform the necessary inspection, repair, and coating of the internal shell of a power silo.


A defining aspect of our approach was our dedication to streamlining the professional engineer analysis and stamping process, thereby minimizing the time involved. Drawing upon the invaluable field experience of our former scaffold foremen, who have transitioned into design professionals, alongside their extensive engineer and design training, we effectively accelerated the process while upholding the highest standards of safety and quality.


Undertaking the design of a scaffold for this project presented us with a particularly intricate challenge. The unique cone shape of the silo demanded a highly specialized solution. With an overall dimension of 66 feet wide and 108 feet tall, our scaffold design provided a spacious and efficient workspace for the necessary tasks. To ensure both safety and functionality, we strategically placed work platforms every 6 feet and 6 inches, following the slope and curvature of the silo.


One hurdle we encountered was the 60-degree slope of the silo's base for the first 60 feet. However, our team provided a secure solution utilizing swivel screw jacks and bracing. This approach ensured the stability and safety of the scaffold throughout the entire project.


"I've tackled some challenging designs, but the cone shaped structure for the power plant was unlike anything I've ever designed before. Ensuring its safety and efficiency was a complex puzzle with so many moving pieces that had to fit together perfectly and there was hardly any room for error. It's always rewarding to see a design come to life, but this one was particularly special. We're all proud of the countless hours and dedication that went into its creation and execution. I know our client was happy and that's what matters most." - Miguel Flores, Lead Designer

In terms of design elements, we predominantly utilized system scaffolding (Ringlock) while minimizing the use of tube and clamp components. This intentional choice not only enhanced overall efficiency, but also provided convenient access to the scaffold through the incorporation of a thoughtfully designed staircase.


The construction of this project took place during the first week of May at the Omaha Public Power District site in Omaha, Nebraska. We are thrilled to report that our team successfully delivered on the work scope, which encompassed washing, inspecting, repairing, and coating the internal shell of the power silo.


This engineered scaffold design project stands as a testament to our commitment to providing safe, innovative, and practical solutions tailored to the specific needs of our esteemed clients. By leveraging our team's unique field expertise and harnessing cutting-edge design techniques, we ensured the utmost safety, efficiency, and successful completion of this critical infrastructure maintenance endeavor.
