TEK1’s Steel Detailing for Sydney Metro – Resolving Design Challenges – 8

In this blog, we share a proposal we made to the builder to make installation easier on-site.

In the OTE platform steel, we provided a PSD beam (OTB5) to support the platform screen doors below. These beams will later need to coordinate with the door manufacturer’s system.

However, in practice, structural steel is rarely placed in the exact designed level due to factors like concrete alignment, mill tolerances, and site conditions. If the beam is installed as per the design without adjustment options, it may not match the required level for the doors.

To solve this, we proposed adding packer plates so the PSD beam level can be adjusted during installation.

The client accepted our proposal, and this solution will make the erection and alignment process much easier on site.
