With the UK government insisting on the use of Building Information Modelling (BIM) for all their projects starting from 2016, the use of the BIM process will become inescapable. Although BIM has been available for many years this decision has prompted a surge of BIM requests within the construction industry. This has filtered through to the lighting industry and many companies are establishing BIM teams to deal with this influx. This paper takes a look at what BIM is, the benefits it can bring in an ideal world and some of the issues to getting started. It will look at the queries that are being raised from different users within the lighting industry and what resources are available to deal with these queries. Talk by Kelly Smith, Zumtobel Group

Editor's Notes
- The Danish physicist Neils Bohr once said – If quantuum mechanics hasn’t profoundly shocked you, you haven’t understood it yet.
- The concept has been around since the 1970’s First mention of ‘Building Information Model’ used in a paper in 1992. Initially pushed by architects because of the good rendering and the way a building could be easily chopped up and sectioned. Changes could be made easily and quicker.
- it isn’t AutoDESK Revit MEP or Graphisoft ArchiCAD or Tekla Structures or Bentley Hevacomp Mechanical Designer. BIM is a process.
- Data comes first. Think of the model as a skeleton – and the data is the muscles, tendons, blood network etc you need to need to make the body work. To make BIM work – you need the data.
- Paper drawings etc can be classed as level 0 BIM and indeed the paper drawings are still a legal requirement. 2-D and 3-D cad are Level 1 BIM Level 2 which is a collaborative data enriched model. So when some-one asks for a project to be done in BIM – they usually mean Level 2 BIM. Note the wedge shape
- Clash detection is just one of the benefits of using the BIM process. If you have a recessed light fitting and someone wants to also put pipework behind the ceiling it may be that there is not enough room and this feature will tell you. There are some companies who offer clash detection software and will do it for you.
- Temporary structures with clash detection 9, 10 & 11D – too far.
- With clash detection, temporary structures allowed for, costing's and ease of facilities management – BIM must produce some cost savings. Figures are from NBS - construction industry is traditionally a wasteful process. Generally insurance premiums are lower for BIM projects.
- Green building studio is part of AutoDESK We are all tasked with saving energy – dimming & controls are becoming second nature for lighting designers and we all have to deal with the dreaded recycling bins. Although some councils are so fussy about what goes in there that you wonder why they bother. Information like circuit watts, power factor and apparent load can be added to electrical equipment and these packages can do an analysis. Useful if you are trying to match the requirements for Part L or get your BREEAM points.
- As I have mentioned a few times – it is the information behind all the models that is important. But one of the other useful things about these models is that geometry is parametric. If you have luminaires and pipework you can lock those to the ceiling – then if you decide to lower the ceiling – they will all move with it. And if you have set your model up correctly., you can schedule out how much more piping you might need. You can lock load bearing structures into place and you can use AutoCAD drawings – both 2-d and 3-d – as templates. So instead of drawing out the lines, circles & arc etc you want you import a drawings and pick the stuff you want.
- Length is parametric, the width is parametric and the suspension height is parametric. Louvres are locked to the sides – when the width expands so do they and they are arrayed along the length with the quantity set up depending on the length. Only one model to do the lot.
- Different types of parameters. Louvre quantity Photometry type & orientation Different datasets with different manufacturers – COBie & CIBSE
- Graph illustrates a great example of the benefits of BIM adoption. This case study is also on the NBS web site. Who owns the savings? Initial costs may mean running at a loss for smaller companies
- Expensive and you need to keep staff trained in the lasted revisions and what’s happening in the BIM world in general. If you are creating families – these have to be updated with new information or revised if necessary. Its best to have dedicated personnel – if you can.
- Some software can’t be save to a lower release like you can with programs like AutoCAD. So you do need to be careful when working on a project that you are working in the right revision. Models are rarely updated once project starts. If lighting put in a building and then 2 years later project is completed – some-one needs to check lighting has not changed or been made obsolete.
- The confusion is getting better – more standards are coming out and more experience is being gained as projects are completed. The problems with intellectual rights and responsibilities are being solved but it is a slow process and there are still problems with things like when to do handovers or data drops
- Mostly family creation Watermarks can be stripped out and the data behind the model can be changed. Just try to make it as difficult and time consuming as you can.
- COBie was initially used by the American military and in essence it is a big spreadsheet BS1195-4 should be released about the beginning of October and this will have COBie in it and the good part is that it will be free to download, data drops etc which includes costs and carbon. IFC – industry foundation classes. The IFC data model is intended to describe building and construction industry data – its platform neutral, open file format specification not controlled by a single vendor. The IFC specification is now run by buildingSMART.
- Soft Landings are about adopting a mind-set and a process to align design & construction with operational asset management and purpose. Essentially it means that throughout the entire process the needs of the end users should be considered by whoever is involved in that process. The CIC is the construction industry council and the idea of the regional hubs was to raise awareness of BIM and facilitate early adoption of the process and working methods.
- RIBA is part of NBS. You can download the digital plan of work but even that still calls for industry input
- In the CIBSE journal Only one company – One Point Design – was actually the Revit user Remember BIM is meant to be a process from design conception right through construction and handover, continuing through facilities and asset management and even into decommissioning.
- Well we have level 3 BIM – which is integrated BIM.
- PAS 1192 parts 2,and 3 which are available at the minute and there was lots of discussion on asset management and data drops. There are also a long list of definitions and if you like 3 and 4 letter acronyms – you will love these standards
- At because this is such a fast changing process, some definitions are changing. What is currently written in the PAS as requirements for level 2 BIM, might not be what you though was.
- This was from Nigel Davis of Evolve consultancy. They asked on some of their projects what they though was the level of BIM they were working to and incredibly 22% said Level 3. Then they did an independent audit and the numbers changed somewhat.
- This was from Rene Schumann – from ViCon. An entire city has been modelled. And this was mainly for infrastructure – rail, highways and tunnels. Other countries are also using BIM for infrastructure – America, Canada and also in Brazil & China. Brazil was 3rd in number of academic paper published around BIM behind USA & Sweden.
- Check the BRE website
- The rest of world will soon follow.
- One of the more interesting talks was about cyber security and protection of assets and of designs.
- We started with a quote from Neils Bohr so it feels only proper to let him have the last word – he is once quoted as saying – Every great and deep difficulty bears in itself its own solution. If forces us to change our thinking in order to find it’ To find a solution to get the best from BIM – we WILL have to change our way of thinking.
