Light gauge steel design and detailing for single-family home in Sacramento

This project entails a two-story residential house, composed of two wings with a joining hall between them.

ORIGIN was enlisted to develop structural construction drawings and to conduct a structural analysis of the LGS framing and the building’s foundation.

Given the builder’s possession of a Framecad rollformer, CNC files for LGS panel production were also a requirement.

Input: Architectural drawing set.

Project deliverables:

• Structural drawing set;
• Structural analysis report;
• LGS shop drawings;
• Framecad CNC files for LGS panel production.

The process begins with a careful examination of architectural drawings, from which we conceptualize a structural scheme. Any discrepancies or issues that arise are promptly communicated to the architect for modifications. Following this, we translate the PDF architectural drawing set into a detailed Revit model, which encompasses the foundation, floors, roofs, and walls — the latter acting as the foundation for the impending LGS framing.

Post the completion of the Revit model, we embark on the creation of LGS framing using Strucsoft MWF Advanced Metal software. This Revit add-on furnishes an array of tools tailored for the automated creation of LGS framing. Once completed, we turn our attention to modeling the foundation.

After preliminary structural modeling, a comprehensive structural analysis ensues. Calculations for LGS framing are conducted via SCIA Engineer software, while masonry walls and foundation calculations are performed using Excel and Mathcad spreadsheets. Our computations are aligned with various international codes, the details of which can be found at the end of this page.

Following plan approval, LGS panel production commences. Initially, individual members of LGS panels are produced. This is facilitated by exporting a CNC file from the Revit model, compatible with the Framecad rollformer. Once these profiles are run through the machine, the second step involves the assembly of LGS panels from these members. We offer detailed shop drawings for each panel, showcasing labeled and dimensioned members.
