OpenBIM in Action: 480 Hay Street, Perth

BPi has revolutionised lean construction using a true Open BIM workflow and best of breed software in their newest development – 480 Hay Street, Perth. The development, a $500 million multi-storey office tower combined with the new 360 room 5 star Westin hotel, is being built in the middle of the Perth CBD and is a flagship project for Open BIM in Australia.



“For the past 50 years, the Australian construction industry has become less and less productive despite the technologies that are out there. We have seen the implementation of BIM in Scandinavia see a 1% productivity waste versus Australia at 29% waste,”  says Levi Naas, VDC Manager at BPi.

Open BIM is a universal approach to the collaborative design, construction and operation of buildings based on open standards and workflows.  It allows for the best of breed tools to come together using non-proprietary, and international standards such as Industry Foundation Classes (IFC) and BIM Collaboration Format (BCF) for data sharing between project participants such as architects, engineers and contractors.

“Open BIM is the only way forward for the AEC Industry in Australia,” Levi Naas says, “Normally interoperability between software platforms is highly challenging but with Open BIM and the IFC, software platforms like ArchiCAD and Revit can actually share building information.”

Along with their use of Open BIM, BPi have also used GRAPHISOFT®’s innovative mobile software solution BIMx docs, which allows its stakeholders to navigate through their project by moving between the 3D model and the 2D drawings on their tablets.  This ground breaking application is already saving time and money.

“All delivery for the project’s documentation to the site is through BIMx®. We are contracted to convert Revit and Tekla models and any other documentation that arrives in 3D or 2D into ArchiCAD and out to BIMx Docs on the iPad. This means that every person that goes on site, has an iPad ready to go with the 3D model and all documentation for the entire project,” says Colin Dibb, VDC Services Director at WEBBER Australia.

With Perth fast becoming a Mecca for technology and innovative techniques, it comes as no surprise that investors have come in and they’re pouring a lot of money into innovative technology.

Using an Open BIM Workflow, best of breed software and a lean construction approach, BPi is reducing waste on this project and targeting a minimum 5% reduction which will mean hundreds of thousands of dollars in savings.

The project is due for completion in 2017.



Project Overview

480 Hay Street, Perth is a $500 million mixed-use redevelopment offering a luxurious 5 star Westin hotel, office, retail and dining space options for locals and visitors alike. The project, managed by BPi, is the first of its kind in Australia to adopt a true Open BIM approach.


About BPi

BPI, is a joint venture between BGC Australia and POSCO E&C Australia, and was developed to take the genesis of an idea around convergent technologies and lean construction theory to demonstrate how it can save money and reduce waste within the Australian construction industry.

About OpenBIM

Building Information Modelling (BIM) is about modelling and improving information flow throughout the construction lifecycle.  Originally, the term applied to building construction projects, but it now encompasses infrastructure through to operations and maintenance.

OpenBIM is about recognising the need for vendor-neutral (non-proprietary) methods of exchanging information throughout a project.

About IFC

IFC (Industry Foundation Classes) is an open, neutral data format developed by BuildingSMART International to be a common data schema (IFC) making it possible to hold and exchange relevant data between different software applications.

IFC Tools

GeometryGym for Data Exchange
GeometryGym’s Jon Mirtschin is a very interesting 3rd party developer who, through his early adoption and experience of IFC4, has been recognised by buildingSMART International for his development of IFC exporters/importers for different tools.  GeometryGym has had experience with very complex geometry from Rhino/Grasshopper and enabled editable IFC families within Revit. He has also created intelligent Tekla importer/exporters using IFC format too.

His blog shares his latest work and development of a c# code libraryc# library as a means to generate and export the IFC files, but the scripting aspect of it is opensource on github. Mirtschin is currently working on a project for buildingSMART to generate sample IFC4 files.

iConstruct’s Smart IFC Exporter V2.0 for IFC Exporting
The second incarnation of iConstruct’s Smart IFC Exporter allows the user to map Navisworks selection and search sets to the IFC 2×3 schema. Significant performance improvements of up to 200x faster over the last release have been achieved through optimizations and using a new more advanced IFC engine. Also the output IFC file size has been reduced to less than half of the previous version.
