Firstly, I think that 3d model works in regards to clarification of information, it gives the client, contractor, fitter a better understanding of the way the components are assembled. Being able to slice through a .DWF file online can be very helpful, in regards to a sectional view of a particular area of the construction / elements.
Secondly, having very complex arrangements display in three dimension, for example a multi faceted roof. Being able to display this in 3d really helps the manufactory of the roof understand the finished product/ building should look like, and the best pathway to achieve this.
Thirdly, being able to easily show changes to the model, for example if you wanted to change a hip roof to a gable roof this would take a matter of minutes, then updating the data drop to show the changes.
Fourthly, one of the biggest selling points of BIM is clash detection, this is simply combining the civil, architectural, structural, mechanical electrical model into one. Would be great to hear your thoughts on want works in your experience…
Have came across a concern that was raised on site the other day, Which maybe could have detected before the plumber started his pipe work, but only if the detail of the model includes elements / families such as the WC, mounting brackets, soil stack, bore holes setting out and full mechanical and electrical detail design had been completed in a 3D modeller.
Part of the piece to the puzzle that are missing is that the manufacture of the WC doesn’t have 3D families yet, also the mounting brackets need to be fixed to the precast floor for strength and durability this is not a very complex architectural detail but it has caused many problems onsite. But it does required three consultants mechanical /electrical which in this case is one in the same, the architect and structural engineer to be working on the same design / model at the same time. Which would require collaboration on the part of all the consultants want is the best way of achieving this? Data drops? 3D modelling on a cloud based application?
Some may say this has been done for years using an xref/ external reference in AutoCAD or similar design software, then why do these “defects/ reworking” still occur? Maybe part of the problem is the process? Do design/ build need a lean hard hat on for a while during the re learning of the processes?
Here are some of the qualities that come to mind
- The person must understand the design process; what elements are required at a given time.
- Scope of the project, this requires in depth knowledge of the build elements.
- Managing the information required in the build environment.
- Understanding the build programme and how & when the technical input is required.
- A good understanding of commercial / budgets and what information is required in a tender package.
- Overall good document management, revisions, document processes, collaboration.
- How to work with statutory bodies, highways, local authorities etc…
Thinking about BIM and its future, I wonder if we have already been using a primitive type of collaboration tool, as for many years I have been using notepad to strip text formatting from many different sources such as word, excel and web sources. So many instead us are focusing on want maybe the ultimate format, we could start with maybe want we have been using for years. And maybe start using this in a different way? Sketch up, for example, has been widely adopted as a concept modeller but it lacks the scheduling capabilities, say Revit has, maybe there is another way to look at solving this problem, maybe use an open-source modeller, and have the schedules attached or linked to the model via an export? Such as a dwf format, where it could be published on a website and all could view and use the model attributes as they required…
Where is building information management going in regards to the build environment?
As I see it at this point in time architects and designers are still producing line drawings and schedules in Revit or other 3d modellers, issuing the drawings in a electronic formats such as pdf or similar to the main contractor. Then the Cost consultant is reformatting the scheduled information into cost categories for pricing and budgets…
Shouldn’t we be beyond this stage? Your thoughts…

A number of Design and Decision tools have been developed over the last three years with support from the Technology Strategy Board. They include tools for life cycle analysis, operational carbon reporting, embodied carbon reporting, easy early carbon calculations. Ten tools will be showcased at this event, which will

Yesterday I saw my first small tomato in the garden, and my 4 year old said ” it was huge” this makes me think of the some of the projects and businesses I have been involved in the last say, 15 years or so that I have tried to streamline the design or construction processes. It started in 1999 where I first learned AutoCAD and Architectural Desktop where you built a 3d models in model space and you could extract information from the model such as door and window schedules, equipment schedules and so on, basically anything that you could “tag”.
The UK construction industry wants to become a world leader in building information modeling (BIM) after a Department of Trade and Industry (DTI) report in 2008 found that the adoption of the technology is estimated to have already saved UK construction companies and their clients £2bn per annum.

Tuesday the 18th of June, I attended the BIM for Beginners at the London BIM hub. It was a great environment for learning about Building Information Modelling and its processes. A question was asked want are some of the barriers in implementing BIM in your organisation? I would like to turn the question on it head, and ask what can enable BIM? One of the solutions could be to adapt lean principles to a BIM process? Any thoughts?
