Drivers Behind BIM Part 1

This article is the first of two parts, the focus will be on the drivers behind BIM, why are many companies adopting this new or not so new (depending who you talk to!) way of working. BIM has many believers and just as many critics! But one thing is for sure as it stands, the UK government believes it’s here to stay as well as many of the early adopters who are making whole sale changes to the infrastructure of their project set-ups.

Over the last few years the UK Government has made significant moves outlining where they expect the construction industry to be over the coming years in regards to BIM. The UK Government has mandated that all public building projects will have to be using BIM design processes at level 2, fully collaborative 3D BIM, or higher by 2016.  Francis Maude, Minister for the Cabinet Office has recently stated in 2012 that, “The Governments four-year strategy for BIM implementation will change the dynamics and behaviours of the construction supply chain, unlocking new, more efficient and collaborative ways of working. This whole sector adoption of BIM will put us at the vanguard of a new digital construction era and position the UK to become the world leaders in BIM”.

Now….within this particular article I’m not going to get too caught up in the whole debate of how much of this ‘new’ BIM methodology already existed in certain people’s workflows and how much is a ‘new’ way of thinking. Yes certain collaborative working processes did exist previously, what I feel BIM has brought and is bringing to the table is a repackaging of the best aspects of collaborative working processes and protocols along with new ones as well as establishing further integration of existing 3D CAD technologies and the newer BIM technologies that are sprouting up on what seems like a daily basis!

The Cabinet Office states in the Government Construction Strategy (2011) “there is a detailed programme of measures Government will take that will reduce costs by up to 20% by the end of this parliament”; it is believed by many that BIM will be one of the key factors in achieving this target. I still feel that even with all the good work that the BIM task groupBIM Regional hubs, OpenBIM network and the BIM academic forum are doing more work will be needed to move onto the next phase. We’re at the point now where all the believers are fully on board and committed to BIM ethos. What phase 2 needs to do now is move beyond the tight-knit and familiar group of people who accept and believe in BIM and begin to convince some of the remaining doubters on board. I say some because I feel you will always get some people who don’t like change an d wish to stick with what they know and are comfortable with.

As well as the Government drives i also feel that education has a big part to play in BIM adoption. As discussed in the BIS BIM strategy Report carried out by the BIM Industry Working Group (2011, p6) “key to any successful change programme is communication of the change and adequate support during the process”, part of the responsibility to provide that support will fall on Academic Institutions. The BIS BIM strategy Report (2011, p6) goes on to state that in regards to how training is provided the “recommended solution is a strongly led hybrid provider drawing on the educational and research expertise of universities, the robust experience of accrediting bodies and the engagement of credible industry led best practice, as well as vocational training delivered by CPD or the training supply chain.” From this information it’s clear to me that the incentive or at least the outwardly perceived incentive is that education is seen as a major supporting act. In my opinion however I feel much more has to be done at undergraduate level (UK at least). In respect of this point I also feel further guidance and support needs to be established and clearly set out and put forward to higher education institutes as to what their role is.

Barison and Santos (2009) found the application of BIM in HE to be focussed predominantly on single course integration rather inter-disciplinary. However as we all know by now the application of BIM in the industry is an integrated practice! The aim for education has to be for effective collaboration between different professionals.  This is why I feel that BIM should not only be taught in theory and technical lectures but imperatively all of the knowledge should be brought together in multidisciplinary collaborative projects.

So as you can see there are many factors at stake when we talk about the drivers behind BIM, whether it be Government, Industry or Education they all have a big part to play in the future of the construction sector. What are your thoughts on BIM, do you believe enough is being done touch forward with BIM? Also do you feel it’s he to stay, or is it just another buzzword or fad that will pass? Catch up here next week for part 2 of this article.

What does openBIM, IFC’s and COBie actually mean for BIM?

This weeks article looks at giving a brief explanation of OpenBIM, COBie and IFC’s whilst also asking a few questions on what all this means for the future of software vendors. What does openBIM, IFC’s and COBie actually mean for BIM?. With Autodesk holding a 63% (NBS National BIM Survey) share of the CAD drawing market what affect will this have on open BIM for the future? What does open BIM actually mean and what are these COBie files that we keep hearing about? With these points in mind this week’s article will focus on open and closed BIM and the interoperability of BIM software as well as asking one or two questions about what all this means for the future of an open BIM collaborative working environment.

Closed BIM generally refers to when BIM processes are carried out on a single platform whereas open BIM refers to when the BIM environment crosses multiple platforms regardless of the software vendor, in essence an ‘open’ shareable design environment using open standard data.

To achieve an open BIM project environment information needs to be shared/exported to a non-proprietary format, such as IFC’s. Currently there are strong opinions and voices behind the drive towards open BIM with the Government specifying in the BIS-BIM-strategy-Reports that Maturity Level 4 BIM should achieve “Fully open process and data integration enabled by IFC/IFD.” Many individual BIM experts are also pushing for the drive towards an open standard BIM future.

To briefly explain what IFC data formats are, they are in essence an ‘open’ and neutral data format which set a data standard which if utilised can assist in the ‘interoperability’ between software packages. As stated by BuildingSMART  “Industry Foundation Classes (IFC) are the open and neutral data format for openBIM.” The data standard which has been developed by Building SMART international, if adhered to enables for the exchange of models and information between multiple software types, in essence achieving interoperability.

Interoperability is a significant word which if involved in BIM already you will be more than familiar with, if not it’s something that you will begin to understand the significance as you progress further into the world of BIM. For files and models to be shared and merged amongst multiple analysis tools and offices they need to be ‘interoperable’. If software packages have the ability to be interoperable then it means that time can be saved through not having to continually redevelop new building geometry for each tool that you wish to utilise to carry out your various analysis.  The importance of this interoperability of files and models across all the teams involved within a BIM project is a pressing concern within BIM which is continually being intensely developed.  Interoperability is a key factor that needs to be drummed home when considering BIM and is seen as being a key component in the future success of BIM projects and needs to be carefully considered at every step.

If the work produced by varying teams is carried out and outputted in an interoperable manner then it allows for multiple teams to work collaboratively on a project without necessarily holding the same software skills and licences. When reading and encountering BIM these are key words that you will soon become familiar with; interoperability, collaborative working, shareable data, data integration, IFC’s, data sharing protocols to name a few….all of these words and terms hope to lead the construction industry to one place, a ‘fully open process’ and working environment.

COBie is another tool that is also vastly becoming synonymous with BIM. COBie is a tool which allows for a multitude of non-graphical data and information to be stored in an organised manner, in essence a spreadsheet. All of this data can then be handed over to the client/facilities management department allowing for easy access to a multitude of details post-completion without having the unenviable task of sifting through a mass of fragmented documentation looking for specific details such as the manufacturer’s contact details of a door handle! With COBie the intention is that all of this information can be kept in an up-datable database which can be easily accessed and kept up to date throughout the whole life cycle of a building, from concept through to demolition. Interesting further reading on COBie can be found at NBS by Stephen Hamil.

It is argued that this topic of interoperability of file formats and software packages will be a major factor in determining BIM’s success and whether it’s a smooth transition from isolated design practices to a truly collaborative BIM environment. Software programmes such as REVIT can sometimes be referred to as closed BIM, but I feel this is not a clear defined point as REVIT does have the capability to export file types in the ‘open’ BIM IFC format which allows for interoperability between designs and models. For instance REVIT can export all of the information and modal data from REVIT in the IFC data format which can then be imported into various other software packages, beyond the Autodesk circle of software.  So with this in mind you have to be careful when considering what is truly open BIM and what is closed BIM as the boundaries are not always clear.

The voices behind ‘open’ BIM are actively encouraging BIM practitioners to utilise the IFC data formats and open BIM standards, with part of the hope that no one software vendor will have a monopoly on the market. According to the recent NBS NationalBIM Survey 2013, within the scope of their research pool Autodesk currently hold a 63% share of the CAD drawing market so clearly they have a large proportional share of the market. What will be interesting over the years to come will be to see how this large market share affects the progression and evolution of BIM in the coming years. Will Autodesk’s share open up or close down the interoperability of BIM? Are Autodesk going to be happy to push forward with open BIM or is it in their interest to actually tie practitioners into their product package? This is something that will be interesting to see how it pans out and how far down the open BIM road BIM can progress with Autodesk and the other software contenders a clear defining factor in how ‘open’ BIM becomes.

 

To collaborate efficiently with a goal at reducing cost, time and carbon central to the ethos of BIM then in my opinion surely we need to push forward with an open approach to BIM sharing standards. I feel that with the research being continually progressed by the likes of BuildingSMART, NBS and the OPEN BIM Network as well as many others a collaborative open BIM future is possible and with the likes of the big guns within the software industry supposedly on board than surely it’s just a case of how do we get there rather than should we head in that direction?

 

Do you feel an open BIM future is or should be the only way forward for BIM or do you think one software vendor will end up ruling the roost and lock down the market? Please feel free to add to the discussion further.
