The Open Geospatial Consortium (OGC), an international standards body like buildingSMART, only for the spatial industry, has recently released the first draft version of a new proposed standard referred to as LandInfra. The draft is out for public review, but the due date for responses is coming up fast on 2 March 2016.
The stated goal of the standard is, “to establish and document a common set of concepts that spans land and civil engineering infrastructure applications. It does not attempt to redefine application-specific concepts, but merely presents a common set of concepts from and to which the application concepts can be understood and mapped. This includes information relevant to those concepts as well as relationships that exist between the concepts.”
A core concept that is defined in LandInfra is the alignment geometry of linear infrastructure. Significantly, this was developed in close cooperation with buildingSMART so is conceptually equivalent to the recent IFC extension for alignment. It represents a strong commitment by both industry-based standards organisations to cooperate on the development of consistent standards across the spatial and construction domains. This is critically important as BIM becomes increasingly adopted across the infrastructure domain.
Having said that, LandInfra addresses several infrastructure types, including roads, railways, survey data, land features and “wet” infrastructure (such as culverts, channels, dams, drainage, etc.). That means that OGC are starting to establish spatial standards for modelling these entities well ahead of the ability of buildingSMART to develop construction information standards for those entities. Arguably, the purpose of the two standards (IFC and LandInfra) is different, the former focussed specifically on design and construction, as well as asset management. It remains to be seen how this standard may affect the development of IFC extensions for infrastructure.
The draft LandInfra standard can be found here (here)

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…
That’s a wrap!
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.

The release of ACIF and APCC’s document ‘A Framework for the Adoption of Project Team Integration & BIM’ in early December last year gave us a solid background of the BIM landscape in Australia and New Zealand, pointing out the problems and challenges within industry, ie. government agenda versus supplier agenda. However what it lacked were solutions for whole of industry to progress BIM take up and a meaningful commitment to change the way we work on a large scale in Australia.
On the 26th June 2015, the ACIF and APCC jointly released their most recent companion document to the Framework, entitled “Building and Construction Procurement Guide: Project Team Integration and Building Information Modelling (BIM)”. The aim of the guide is to assist industry stakeholders in their adoption and implementation of PTI and BIM through comprehensive instructions and guiding principles for each procurement model, how to tender and select the right BIM team and how to manage the project using BIM at the outset.
The Procurement Guide addresses many of the standard questions that clients and project teams, with limited BIM knowledge, are looking for, via a step by step and encyclopaedia-like format.
The guide provides some considerations for project team collaboration and how BIM impacts this process across the different delivery models. What’s needed however, particularly in relation to scheduling of contributions is a change in the methodology, where construction can be rehearsed over and over i.e brief, act, debrief, brief, act, debrief etc. The current process undervalues this opportunity and briefing documents continue to involve maps, models and explaining the plan rather than opportunities to test virtually and revisit and re-brief prior to physical construction.
Leadership is also a key component that is missing in the BIM campaign to improve building projects in Australia.
Peter Barda, Executive Director for ACIF, who facilitated the accompanying webinar that launched the guide, highlighted the fact that governments have been slow to adopt BIM as a tool and the reluctance may stem from a need to see some completed BIM projects to demonstrate the benefits. Teresa Scott, Executive Director for APCC concurred that governments are reluctant to push BIM onto contractors and are looking for the industry to demonstrate its BIM readiness.
Peter Barda advised that ACIF will shortly be approaching all jurisdictions around Australia with a plan to phase in BIM as part of a longer term opportunity to mandate BIM for projects over a given value. ACIF is keen to work with University and the Vocational Education and Training sectors to “turn out” people who are appropriately skilled to use BIM and who understand how to use the integration process.
The guide doesn’t focus enough on the true benefits of BIM in terms of relationship management throughout a project. Peter Barda did however close the webinar by focusing on BIM success not being about 3D design but being very much about harnessing project team integration and around all consultants, trade contractors and project sponsors having a role in “deciding if BIM is useful or not and deciding how well the team is put together and managed.”
Until, as an industry, we get this depth of understanding across all jurisdictions and the training to support it we cannot achieve better team work through BIM. A project based industry must do things that benefit the project.
The guide alone will not make the impact on industry that is needed to push Australia towards a BIM ready environment. What is clear from this most recent guide release is that until companies can see the immediate personal benefit for committing to BIM as a technology resource – take up here will continue to be slow unless mandated. And this is the problem – the vicious cycle. Industry is busy, there is a lot of work going on, and approvals are at an all-time high.
Countries that are mandating BIM are upskilling their workforce at a significant rate – a workforce that is now eyeing up overseas opportunities. Competition in this space will become fierce and local Australian companies will not be ready or capable to react because of a lack of action today that leverages our high labour costs. Perhaps this is where the Government needs to take the lead to recognise that the industry is BIM ready and capable and to provide that stimulus for Australian companies to invest in the technology to sustain our local industry in 10, 20 and 30 years. This will at the very least put us on an equal footing with those shaping global construction.
We look forward to ACIF’s round of consultations with industry in late July and early August on the development of their Education & Training Skills Sets. This will be a good next step and welcome addition to BIM readiness in Australia.

buildingSMART Australasia is currently in collaboration with SIBA – The Spatial Industry Business Association – to prepare a White Paper for the Commonwealth Department of Communication.
The key focus of this White Paper is on a data policy for the integration of spatial and construction information modelling technologies. This will lay the groundwork for digital prototyping of the built environment at a scale that encompasses buildings, civil infrastructure and urban space into one model, with links to urban contextual data using existing spatial technologies. The ideals reflected in this White Paper is in line with international initiatives and, if supported by Government, will could position the Australian construction industry at the forefront of developments in that area!
The Paper is due for release in mid-July and we will be available through the buildingSMART Australasia Web site.

This VDC documentary was produced in collaboration with GRAPHISOFT and BPi. The article is as published on February 11, 2015 by GRAPHISOFT® with permissions from LCi and BPi.
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.

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.

Some of the biggest buildings of the new-look Christchurch are being put together virtual piece by virtual piece, thanks to remarkable 3D technology.
More than a decade after Building Information Modelling (BIM) made its debut in the construction industry, the concept has been pushed to the point where many of the centrepieces in the rebuilding of Christchurch are being assembled in detail on a computer well before workers set foot on the site.
It comes as the Government starts a BIM acceleration committee, as part of a productivity partnership with the goal of 20 per cent more efficiency in the construction industry by 2020.
BIM expert Jason Howden, who has worked on huge projects ranging from Royal Manchester Children’s Hospital to a 1.5km terminal expansion at Jakarta Airport, has returned to his hometown to assist with Christchurch’s $40 billion rebirth.
His team at architectural firm Warren and Mahoney is now using the technology to tackle several large-scale operations, including three buildings of 40,000sq m, covering a city block.
Because contractors, designers, architects and engineers all worked from a single three-dimensional design, all of the components of a building – from steel girders down to interior fittings – could be designed and positioned into the digital model in a single process.
Once the design was complete, builders on site could use a tablet computer to view the BIM plan as a digital overlay on top of what they were physically seeing.
“A laser grid that is accurate down to the millimetre is projected on the area being worked on – and the tablet computer is able to pick it up and use it to show a render of the BIM, overlaid on a live picture feed so workers can see exactly what the project is supposed to look like and work precisely to plan.”
Mr Howden said this approach allowed construction teams to spot hurdles, make work sites safer, slashed cost and potentially halved construction time.
While New Zealand had lagged behind in its take-up, BIM designing was expected to become more widespread here, and especially in Auckland, said John Walsh of the New Zealand Institute of Architects.
Rolf has more than 20 years’ experience in the New Zealand Construction and Housing Industry and is passionate about seeing its efficiency and performance lifted. As Chief Executive of Masterspec, an industry-owned company providing specification systems and data online to over 1,200 New Zealand design practices, Rolf is a strong advocate for greater industry adoption of the buildingSMART frameworks and resources. Rolf is also a buildingSMART Australasia work group member for BIM Object Libraries and a Board Member of the International Construction Information Society.
Rolf’s BIM Vision: Based on international frameworks, for BIM to become the enabler for greater industry collaboration and efficiency gains throughout the different construction life cycle stages.

When Richard Petrie joined buildingSMART as chief executive officer in 2013, he took on the goal of driving the standards-writing organization’s growth — in order to drive change across the entire architecture, engineering and construction industry.
Having worked in construction as both contractor and client, Petrie has seen firsthand the frustrations of a slow-to-evolve architecture, engineering and construction industry. From within buildingSMART — a not-for-profit organization that has been working to standardize the language and processes of BIM users since 1995 — Petrie has observed an increasing emphasis from several European governments on improving construction efficiency.
“All of those governments have very serious social needs that they have to fulfill with increasingly limited budgets,” Petrie says. “Completing these projects in the best way possible is very important, and you can’t do that if you don’t have accurate and clear data.”
buildingSMART is setting out to provide that data by leading the entire building industry into the digital economy.
There are two key challenges in architecture, engineering and construction industry that buildingSMART is seeking to address.
First is the fragmentation of the supply chain. As designers, builders and owners expand their focus to the entire life cycle, it becomes increasingly important to understand how each component and system impacts others. While savvy suppliers are integrating vertically, providing inter-related products, services and knowledge, many designers are finding the information they need through sharable information made possible by BIM.
Second, Petrie finds, construction clients are rarely well informed about the construction, building management and asset ownership process, which means they are also fragmented. For example, the efficiency to which buildings are designed isn’t always met in operation. This is in part because product data isn’t easily transferred from designers and builders to owners and facility managers.
“Altogether, this disjointed relationship with clients and the fragmentation of the supply chain is a great drag on the transformation of the industry,” Petrie says.
Creating a Universal Approach to Construction
buildingSMART describes openBIM as a “universal approach” to the collaborative design, realization and operation of buildings based on open standards, such as its IFC family of standards. This approach allows all project members to participate in modeling, regardless of the software tools they use; it creates a common language for widely referenced processes; and it provides one system for housing asset data over its entire life-cycle.
Petrie sees openBIM as a solution to the industry’s fragmentation challenges and buildingSMART as a path to the significant opportunities for improvement in building and infrastructure cost, value and environmental performance.
“I believe those opportunities are only truly available with open international standards and, in order to create those open international standards, a neutral entity for the development and promulgation of those standards is needed,” Petrie explains. “That is the role buildingSMART International is taking on.”
With its newly defined vision, the volunteer-driven organization has made major headway in the past year. From creating new standards to defining data to the harmonization of processes across the supply chain, the group has demonstrated real progress and results.
The Push for Interoperability
The group’s push for progress aligns with demand from several governments. As a case in point: Petrie indicates the UK government’s push for interoperability as an example of where openBIM is heading.
While the UK has had requirements for open data since 2012, in 2016 the government will formally launch a program in which procurements must use BIM Level 2 documents.
This set of methodologies is designed to introduce the construction supply chain to trading and operating in a data environment, allowing the government to focus on the strongest leaders and drive value for its spending programs.
It’s a demand driven not by technology, Petrie says, but a cultural shift resulting from seeing real change in how each construction dollar is spent. “That is the reality that will provide the real driver to ensure that this program moves forward the way we hope it will,” he says.
Petrie adds that thus far the group is achieving its predicted targets in the UK, and work is underway for a Level 3 program slated for 2020-2025.
The Smart Future of Building
To expand the organization’s work, Petrie is seeking to build a community of experts to ensure that future standards accurately reflect the needs of real-world users. Volunteers work at both the international and chapter level, in an integrated process for developing new standards and deploying them into user communities.
Membership in buildingSMART International (and buildingSMART Australasia) is open to companies, government bodies and institutions from around the world. Dassault Systèmes joins buildingSMART as an International Member, with full voting membership rights on the new Standards Committee and membership rights with buildingSMART chapters.
The company joins other leading proponents of openBIM that recognize the benefits from openBIM can achieve the greatest impact and momentum by working together in a common community.
Members benefit from the collective activities of other members locally and internationally, and play an active role not only in identifying issues, but also in the development of solutions.
“The nature of buildingSMART is that it is a voluntary organization where solutions are developed on a mutually supportive co-developed basis, and so we need members to be active in our community,” Petrie explains.
Petrie acknowledges that it will take time to develop and communicate the organization’s mission, but, he adds, “The changes that we are hoping will be available as a result of these new standards will not only affect the technical communities, but will have implications for the way in which companies function.
On 26/2/2015, Rt Hon Dr Vince Cable at a site visit in London announced the launch of Digital Built Britain, the UK Level 3 Building Information Modelling program.
The works will build a digital economy for the construction industry in support of dramatically improving delivery, operations and services provided to citizens.
The programme will build on the standards and savings delivered by the BIM level 2 initiative which has been central to the £840M savings achieved on central public spend in 2013/14.
