About the project

The Northumberland project is comprised of a 13-level office building and a five-level companion building, located in Collingwood, Melbourne. The site contains a lettable area of over 15,000m² and incorporates an existing telephone exchange building into its design.

The Task

Our drafting services included the mechanical services and hydraulics drafting.

The Challenge


Due to the project incorporating the existing telephone exchange building into the design, the space available within the companion building riser, is quite limited. As such, this provided a challenge in order to fit the required mechanical services within the riser.


The size of the project meant the structure needed to be supported and strengthened  by significant structural steel. Together with tight time constraints and limited ceiling space, the hydraulic riser roll over was not code compliant and also not able to be built.

The Solution


Drafting Solutions was able to use modelling and construction expertise to produce a solution that not only allowed all the required services to fit into the riser, but also allowed for the ductwork to be installed smoothly.


Drafting Solutions led a complex process of not only redesigning the hydraulic system so it was code compliant, and able to be built, but also assisted with reducing the impact on architecture and other trades, while meeting the time constraints.
