Building Information Modelling (BIM) for Lean Construction.
with Mr. Ralph Montague
Wednesday 27th of July 2016, 15:00 – 16:00 GMT
Ralph Montague, Architect, BArch MRIAI, is managing partner of ArcDox, a specialist BIM consultancy practice based in Dublin, Ireland, providing professionally managed advice, production, support, and training services to the construction industry. A registered architect with over 20 years’ experience in managing large projects, Ralph endorses BIM as a more cost effective and highly efficient way of producing and managing design and construction documentation. And improving the building process.
As chairman of the Royal Institute of Architects of Ireland (RIAI) practice sub-committee for BIM, and coordinator of the Construction IT Alliance (CITA) BIM Group, Ralph has been instrumental in leading the development and adoption of BIM in Ireland since 2009. Ralph is a part-time lecturer at Trinity College Dublin School of Engineering Post-Graduate Diploma in Project Management, and more recently has been representing the RIAI on the Architects Council of Europe (ACE) BIM Working Group. He has also previously represented the National Standards Authority of Ireland (NSAI) on the European Committee for Standardization (CEN) BIM technical working Group, and is a board member of the recently formed national BIM Council.
BIM for Lean Construction
What is BIM? Why is it important?
BIM is the Lean Production, Management & Exchange of Information about Buildings.
Lean depends on good quality, accurate, timely, digital information.
BIM & Lean go hand-in-hand.
There were some questions that we could not answer during the webinar, so Ralph Montague has kindly agreed to answer them offline, and we have provided the answers here:
Other countries in Europe have other more integrated standards that focus on information rather than process – Are they not relevant?
As noted in the presentation, BIM is both a process and a deliverable. Information standards support the “deliverable”, and there are already international open standards for the information (ISO 16739 (IFC), ISO 12006 (IFD), and ISO 29481 (IDM), on which most of the other European & US standards are built. BS1192 & PAS1192-3 (which will become ISO19650) focus on the “process”. It is not that the UK standards are competing with European standards, they are just dealing with the process aspect, while the ISO standards deal with the information aspects. They work together.
Intellectual Property seems to be a source of Pseudo BIM across projects in Ireland. What can be done to change this/is it being changed?
The implementation of a contractual agreement, which clearly sets out the rights, responsibilities, liabilities, exclusions etc., including IP and copyright, will resolve these issues. The CIC BIM Protocol is a standard addendum to all appointments and contracts, which deals with these issues. This needs to be implemented by the legal/commercial team.
Do you think the processes which are described in PAS 1192 are sufficiently detailed or would one or two more levels of detail be useful (and still generic)?
The specification in PAS1192-2 sets out what needs to be done, but the project specific detail will be considered/determined when you are preparing EIR’s, BEP’s, MIDP’s etc (as set out in PAS1192-2). PAS1192-2, is generic enough, to be able to deal with any project type, but also specific enough, to set our exactly what needs to happen, in terms of defining the detail in other documents.
Where should an enterprise start? Implementing Lean or BIM?
I would suggest that you start by engaging with organisations like Lean Construction Ireland and CITA (Construction IT Alliance) – these are driving Lean & BIM in Ireland. Also there is a lot of information online (Google, YouTube etc.). The transition to Lean & BIM is a journey – like any journey, you need to know where you are starting, and where you want to go, and then plan the steps to get there. Get started, even if with something small, move step-by-step closer to your destination (continuous improvement, rather than dramatic change).
Is Ralph seeing an increase in the volume of owners specifying BIM level2? Or specifying BIM at all?
Yes, there is an increase in owners asking for BIM, in both private and public sector. Also, client are becoming more informed (i.e. it is becoming more & more difficult to “pull the wool over their eyes”). At this stage most people have heard about Lean & BIM, but are not doing it, on the excuse that no one has asked for it. But clients are simply beginning to expect it, and will award the projects to those who offer it.
If lean is about chasing waste out of your processes using simple tools & techniques then how do you convince owners to invest in an expensive piece of software when they may not have seen results yet?
Owners don’t have to invest in expensive software (other than what they are using already for facilities management), unless they have outdated systems that need to be upgraded. Suppliers (Designers and Contractors etc.), who are using outdated drafting and information production processes, may have to invest in hardware, software, training, to achieve a more efficient way of working, but that is not a “project cost” – it is a cost of doing business and being able to provide better, and more efficient services. (You can try to pass this cost onto the owner if you wish, but an informed client is just looking for the end cost of your service – they are not interested in what skills/tools you need to deliver that).
There are plenty of case studies to support the return on investment (for all parties).
If owners ask for Lean & BIM at the right time (before people have already completed a lot of work that may have to be redone), and ask for it in the right way (i.e. following standards), then there should be very little additional cost, as the information still has to be produced anyway, as part of the normal service.
