The Australasian BIM Advisory Board (ABAB) last week held its Meeting in Canberra, commencing with a meeting with the Hon Paul Fletcher, Minister for Urban Infrastructure and Cities. Discussion focused on embedding Building Information Modelling (BIM) into the Federal Government’s Smart Cities agenda and the use of BIM as key to the Federal Government successfully securing a financial return for taxpayers from its unprecedented level of infrastructure across Australia. BIM is one of the components of the data infrastructure necessary to build a smart city. As with all infrastructure, it needs to be planned, built and managed.
The Chair of ABAB Dr Michael Green, who is the Executive Director, Employment, Investment and Trade Policy, Victorian Department of Economic Development, Jobs, Transport and Resources, stated that “the prize for BIM adoption in construction is large. Reports forecast that the wider adoption of BIM will unlock 15–25% savings to the global infrastructure market by 2025. And it is this technology-led change that will deliver the highest impact to the construction sector that has previously had modest productivity gains.
ABAB members who have implemented BIM all agree that it delivers projects faster, smarter, and with less risk.
“$7.5 billion in savings could be realised from the current Federal Government’s $75 billion 10 year infrastructure investment program if the wider adoption of BIM delivered a conservative 10% savings. That’s enough to pay for Sydney’s second airport or to complete the duplication of the Pacific Highway”, said Dr Green.
Population pressures mean Smart Cities have never been more important. As Australia’s population is projected to grow to 30 million by 2030, building more, building better, and building for less is critical.
In addition, the digital revolution in construction helps governments better engage citizens and communities in the transformation of their cities.
ABAB members representing government, industry and academia recognise the potential of BIM to enable governments to build more, build better, and build for less. As major clients in the building and construction industry, when adopting BIM, governments have the potential to improve asset quality and expedite the pipeline of capital works.
Since its inception in 2016, ABAB has made substantial progress against its objective to lead and coordinate the consistent adoption of BIM.
By June 2018, ABAB will provide guidance for clients, their agents and lead consultants on formulating and defining their information requirements for building and infrastructure projects. In addition, ABAB will have produced an Intellectual Property (IP) educational piece supporting all parties to a contract. The final body of work, also expected to be released in June 2018, is a BIM Process Consistency Guideline designed to share best practice in BIM processes and drive consistency across Australia and New Zealand.
At this meeting of the ABAB, government representatives detailed the direction of their government in respect to BIM maturity and strategic direction. “Understanding governments’ intentions underpins the work of the ABAB to drive a consistent approach” said Dr Green. This discussion supports ABAB’s next activity to develop a set of principles for governments’ strategic adoption of BIM.
Governments and the construction industry can benefit from adopting a BIM strategy to improve exports, create more jobs, further stimulate the economy, harness savings to finance future infrastructure assets, and help create a sustainable built environment.
The time has come for all Australian Governments to seize the opportunities offered by BIM. ABAB advocates that all governments should:

buildingSMART Australasia is pleased to announce the release of a new openBIM tool to help with standardising of BIM objects based on IFCs.
Thanks to NATSPEC, BIM object standardisation is now achievable with the release of their BIM Object Properties Generator. This new tool supports the standardisation of BIM Objects across the Australian construction industry. It is an upgraded online version of the current NATSPEC BIM Object/Element Matrix and is more powerful and easier to use. The tool establishes the property sets for individual BIM objects ( elements). The range of properties include ifc, COBIE and a few others. The facility allows users to decide what categories of the property set they want for a particular BIM end-use. As such the tool provides a standardisation template for industry to work with consistently named properties. In addition NATSPEC offers different classification options.
buildingSMART Australasia Chair, David Mitchell praised NATSPEC for the work they have done, adding that it will greatly benefit the industry.
“The Properties Generator addresses the major issues concerning information exchange of BIM objects between disciplines and projects.”
NATSPEC CEO Richard Choy adds, “openBIM is all about the free exchange of standardised information and this new tool will go a long way towards making that a reality, as well as helping to increase productivity across the industry.”
A global approach has been used by including objects based on buildingSMART’s Industry Foundation Classes (IFC), and classification data for major systems such as NATSPEC, UniClass, Omniclass, Masterformat and Uniformat.
Properties can be selected from various sources such as IFC4, IFC 2×3, BIMForum LOD Specification, COBie and NATSPEC. These properties are also categorised by their data type, such as cost, manufacturer and geometric. This allows users greater flexibility in generating the properties that are relevant to them, and to filter these properties to their specific project or object library needs.
Selected properties can then be exported as a PDF or Excel file, from which various file formats can be generated to enable them to be imported into BIM authoring and BIM-ready software applications.
The Properties Generator is suitable for a variety of users including content creators, manufacturers, project teams, and client organisations.
It is anticipated that the Properties Generator will be further developed and enhanced in future releases, including the possibility of adding additional properties as desired by major clients. Refer to the ‘Future Releases’ section on the Properties Generator website for items that could be considered for future additions and upgrades.

By digitizing processes and making organizational changes, governments can enhance services, save money, and improve citizens’ quality of life:
A group of international users want to define a standardised way for setting up a multi-disciplinary project model using IFC format data.
Often a collaborative model project has work commenced without definition of shared model setup
The result is that when commencing design coordination, clash detection etc the discipline models are not in the same location and/or have different storey names & settings
To summarise, we want to define a standardised way for setting the origin of a project model that:
New Survey tools such as Listech Neo are developing IFC support that allows direct integration of traditional survey data. BIM users should be able to access Land and related planning etc data directly from the respective Government agencies.
This project would review and implement a standard way of accessing and incorporating Cadastral data as starting point.
The aim is to ensure the same method is implemented by all BIM Vendors.
Project setup must include the following:
Project setup includes the following:
• defining storeys and/or zoning
• creating IFC high level entity structure (ifcProject, ifcSite, ifcBuilding, ifcStorey, ifcSpace) & GUIDs for collaboration synchronisation
• checking IFC se[ngs in authoring tools
• export & tes]ng a project Master Template
• crea]ng the discipline model in each team member
• coordina]on IFC En]ty mapping table with project partners • performing itera]ons and comple]on of team model
Want to be involved?
Contribute to more efficient open BIM model collaboration.
It’s desirable we have representative from as many authoring tool users as possible, so pass the message on to your clients, consultants, contractors, suppliers etc…

BRIDGING THE GAP WITH 3D BIM TECHNOLOGY
FEATURING SYDNEY HARBOUR FORESHORE AUTHORITY
WAYNE SAHLMAN, SENIOR FACILITIES SUPERVISOR
buildingSMART Australasia together with ZUUSE and PDC would like to take a moment to thank you for your support of the 2015 Seminar Series: BIM in Asset Management.
The feedback has been overwhelmingly positive and I am sure you agree that the Pyrmont Bridge project is a fantastic reflection on true BIM and innovation in asset management.
We all know that BIM is fast becoming the Holy Grail in facilities and asset management. But how is BIM being applied in the real world today? Is it working? What results are being achieved?
This Seminar Series addressed these questions and more with a case study presentation from the Sydney Harbour Foreshore Authority (SHFA) on the century old heritage-listed Pyrmont Bridge, a major Sydney landmark that attracts more than five million pedestrians each year.
Wayne Sahlman, Senior Facilities Supervisor at SHFA, presented a case study on the 3D BIM solution that has been implemented for the Pyrmont Bridge.

New Zealand has taken another major step forward following the release of the New Zealand BIM Handbook in July 2014, supporting the Handbook and outlining the productivity benefits of BIM in the ‘BIM in Action – Case studies’ (linked below). Providing a platform to develop further BIM protocols and tools to support the industry in working in a more collaborative and efficient way.
The NZ BIM Acceleration Committee has continued with its cascade strategy that targets New Zealand key clients by promoting the adoption of BIM use and by raising awareness of the benefits that BIM can offer. The Committee’s primary project aim is to have Government as a BIM client by creating and supporting the demand for BIM use in central Government construction clients.
In the last quarter the Committee has identified, and is in the final stages of securing, a resource to identify potential major government construction clients who could benefit from the use of BIM, to identify the potential barriers to their using BIM and addressing as many of these barriers as possible. There is a real opportunity for synergies between the Committees objectives and those of Government Procurement from this type of arrangement.
Training has been identified by successive market research as a core item to overcome the biggest road block to a wider BIM use.
A ‘Best-Practice BIM in New Zealand’ two-day workshop is planned for early August across Auckland, Wellington and Christchurch with the intention to provide attendees with a robust fundamental knowledge of BIM in New Zealand.
Also, a two-day ‘BIM training for practitioners’ course is currently under development which has already confirmed interest from 130 participants. The course will be run by the Building Research Establishment (BRE), and will be tailored for NZ and aligned with the NZ BIM handbook.

Special mention to the videographer, Alex Chomicz, and the Musical composer, Gavri.
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.
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.
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.
GRAPHISOFT® ignited the BIM revolution in 1984 with ArchiCAD®, the industry first BIM software for architects. GRAPHISOFT continues to lead the industry with innovative solutions such as its revolutionary BIMcloud®, the world’s first real-time BIM collaboration environment, EcoDesigner™, the world’s first fully BIM-integrated “GREEN” design solution and BIMx®, the world’s leading mobile app for BIM visualization.

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.
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.
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.

For many years now prefabrication has been seen as integral to greater efficiency in building construction. Earlier manual 2D CAD systems relied on a product of specified fixed characteristics, mass produced to reduce unit cost; however, this approach never satisfied design flexibility or innovation of product and led, in its worse outcomes of the post-war housing boom, to using concrete panels of small range and adaptability. An ugly truth.
Meanwhile, in advanced manufacturing sectors such as automotive and aerospace, techniques for mass production and robotic procedures have had a revolutionary impact, and now, with the advent of BIM, that revolution is extending into building and construction.
The advent of BIM has produced a reliable method to prototype in 3D objects and its adoption is on the increase, particularly in HVAC system disciplines and supply chains with the work carried out by BIM-MEP AUS. Its advantages are a relaxation of constrained product design, leading to better performing buildings enabled by optimised products with significant off-site industrialised pre-assembly and prefabrication systems. There’s no doubt prefab is on the move.
Examples of the successes of this new approach are the new Royal Adelaide Hospital and the Sunshine Hospital Development on Queensland’s Gold Coast where BIM and prefabrication combine to improve design solutions, bring greater consistency in building and manufacturing processes, reduce on-site errors, enhance a smarter and quicker facility development process, employ a more skilled workforce and add to increased safety.
So what are the key technical challenges to further advancing this integration and continuing the prefabrication revolution?
It’s buildingSMART’s central vision to have an Australasian building and construction industry that collaboratively shares and maintains information about facilities and infrastructure in a manner that optimises the quality and economy of regulatory approval, design, construction and operation of the built environment.
We encourage greater industry collaboration, communication and coordination to properly secure openBIM standards endorsed by government agencies – like transport, health and schools – as well as private sector owners to ensure universal acceptance and applicability.
NATSPEC, with support from groups like buildingSMART Australasia, AMCA (Air Conditioning and Mechanical Contractors’ Association of Australia), Construction Information Limited New Zealand, APCC (Australian Procurement and Construction Council Inc.) and
ACIF (Australian Construction Industry Forum), are preparing proposals to address this issue including the development of a National – Australasian – BIM Object library. Excitingly, we had a real breakthrough on the 2nd December, 2014 for ‘whole industry’ collaboration when a national response resource was allocated to realise the adoption of a new Project Team Integration (PTI) and BIM framework across the Australian building and construction industry with “The Framework for the Adoption of Project Team Integration and Building Information Modelling”, a national first. The hope is this is but the first step in achieving the cooperation required to further advance the building and construction industries in Australasia.
The extension of BIM into the full suite of networks and infrastructure adds to this task, as well as providing new resources and the possibility to set up a truly Australasian process of implementation.
