TEK1’s Steel Detailing for Sydney Metro – Resolving Design Challenges – 6

In this blog, I’d like to share an issue we faced related to hanger locations.

In this job, the floor steel was supported from the slab soffit. Initially, we placed the hangers as per the design drawings. However, during coordination with the concrete model, we discovered a slab void exactly at one of the hanger locations — meaning there was no concrete support available for that hanger.

Fortunately, we identified the issue before fabrication and raised it with the respective manager for correction.

When detailing steel, especially hangers or supports connected to concrete, it’s crucial to check the concrete model. Focusing only on the steel scope can lead to such clashes. Always verify slab and concrete details at the steel connection points to avoid costly rework later.
