Siphonic Scope: Provide main and overflow systems to all box gutters, 6 systems in total.

Key Points: Being a University laboratory, the mechanical plant room had many more services than your typical office building. With that in mind the co-ordination and routing of the siphonic system was extremely complex and time consuming. It was essential that the designs were spot on in order to facilitate a smooth installation for hydraulic contractor.

Siphonic Scope: Design and install main and overflow systems for the main roof area and the existing sports hall roof.
