IES BIM Faculty - BIM4Analysis Update

Editor's Notes

1. Good afternoon and thank you for joining our 11th Faculty session titles, BIM4Analysis – an update 12 months on.
2. My name is Sarah Graham, UK Division Head for IES
3. Introductions – myself, Doug, Jean Housekeeping – everyone muted, questions collated, responded to and circulated after the session so we won’t be answering questions live Our own BIM AP Douglas Bell will talk through the existing functionality, highlighting what has changed since this time last year. Doug will then go on to present some recent findings from working closely with customers. Finally Jean Carriere will present his BIM to energy modelling workflow, step by step to explain to practitioners how to effect exchange of information between analysis and BIM authoring software.
4. Put a bit of context around todays session, looking at what is happening with BIM globally. Some of the main policy, business and technology drivers for this ‘paradigm shift’ 1. In the UK we have a clear mandate – Level 2 BIM on all centrally funded public projects from April 2016 with the aim of measuring carbon, cost and value across the asset lifecycle. 2. Scotland planning to follow suit with a drive to apply Level 2 BIM on public projects from April 2017. David Philp who is one of the main prtagonists in the Cabinet office BIM Task Group and is heading up the drive in Scotland states that BIM is a key part of the future of the construction industry. Improvements in sharing and analysis of data, within a project. Improving data management and collaboration delivers greater efficiencies through design, construction and operation.’ 3. Echoed in Scandinavia, Swedish Health Service and Finnish and Norwegian state property agencies promote use of BIM.EU Commission funds new Europe-wide BIM alignment project, this week announced. The idea is to give clarity to the industry across Europe. We’re producing a handbook to the guiding principles of BIM, and if member countries to want to instate BIM at a procurement level, there’s a reference book on how to do it.– Adam Matthews, UK BIM Task Group 4. Difficult to get accurate picture of uptake around the world I’ve selected this image produced by Tekla in 2013 which gives an overview of useage and this barchart from a recent McGraw Hill Smart Martket Report looking at the business value of BIM from a Contractors perspective. UoTeesside are undertaking a review which is due for publication mid 2016.
5. 1. Besides policy, the drivers which perhaps motivate the private sector and other regions where there is no mandate are perceived business benefits of BIM adoption. This report, produced by dodge analytics offers an insight into what these are – visulaisation to understand the proposed design, integration of analysis to deliver a better design, coordination reducing errors and saving money, improvement to costs and schedules. 2. Clients in the know in the private sector are pursuing a BIM enabled approach to realise some of these benefits e.g. Crossrail, Kings Cross and Queen Elizabeth hospital in Glasgow. 3. These benefits are focussed on benefits in design and construction, largely as a result of the 3D modelling, coordinated design, clash detection. What about operation and information? Those are the bits we are most interested in and where the –carbon, cost and value – can best be addressed.
6. 1. Performance is less obvious when looking at drivers and success stories we read about. However this is a trend we see emerging. 2. We heard a lot and talked a lot about the performance gap last year, we see BIM as a vehicle to close the gap on the basis of continuity of information through design, construction and operation that a Bim approach facilitates (in theory). This presents a great opportunity. HTM07-02 is an example of a policy document that links BIM with energy efficiency. 3. Sot Landings framework, part of the BIM mandate, aimed at setting performance metrics at the outset of a project and measuring those once the building is operational. Metrics are client defined – what information do I need to run this building, what is important? Cost, carbon, comfort linked to productivity, availability of spaces (overheating). 4. Not much in the way of standards around this yet – LEED M&V, NABERS in Australia looking at POE, BREEAM In Use. 5. UKGBC have launched their Building Performance Task Group to gather industry perspective, not just from the UK, on performance, what does it mean to different stakeholders? How is it or could it be procured, whay is it important – again what are the business drivers? 6. September last year saw the publication of the Wellness Standard, sets out 100 performance metrics, strategies and policies that could be implanted by owners, designers, engineers, contractors, operators and occupier to determine, measure, improve on health and wellbeing of building users. Its suggerste that the standard complements environmental sustainabilityand is designed to work in harmony with LEED amongst other VERS.
7. 1. We may see variability in the uptake of BIM globally, variability in the understanding of what it means and in peoples early experiences. However technology, within the construction industry and within out lives generally is marching ahead regardless. The challenges we face now in trying to get our design technologies to talk to one another will disappear as the demand for better, smarter, safer construction techniques and SMART buildings grows. 2. Digital Built Britain, looks forward to a time (within the next decade) when building information modelling will encompass the IoT, advanced data analytics and the digital economy with the aim of planning new buildings and infrastructure more effectively, build at lower cost and operate and maintain more efficiently. Enabling citizens to make better use of the built environment. 3. We already see a move towards, more modular building techniques and the use of AR to convey information to tradespeople on site. 4. We see our customers changing business processes to streamline information creation and management, moving towards a digital engineering and construction age. These companies rely on current technology but will be best placed to exploit new tech as it comes online.
8. 1. IES invests over ¼ of our turnover every year in R&D, most folks know us for New design/retrofit I,e the suite of design tools that some of you will already be using. But that is only part of what we are about. Our aim is to move people round the virtuous circle…as the drivers mentioned come into play more and more. So from your building model, we can start to link in real data from the building in operation to compare predicted with actual performance – all aspects. Scale that technology up from individual buildings to the district or city level and masterplanning is the link between largescale and new design. our goal is to optimise design and operational performance for any building, district, city anywhere in the world.
9. The VE asw we know it offers a single platform for performance/analysis/compliance through design, commissioning and operation. Maintain the continuity of information by creating, capturing, analysing and exchanging at each stage of the asset lifecycle.
10. Earsly stage design, before a model is available – we can analyse climate and look at availability of natural resources. We can carry out optioneering to optimise the layout of the building within the local environment and subject to its useage. We can evaluate compliance with building codes/standard/regulations with LEED, BREEAM, Greenstar, Estidama, GSAS at different stages – pre-assessment, intermediate and as-built. Carry out systems design, costing – capital and lifecycle. At the commissioning and handover stage use the data to ensure the ‘starting point’ of the building is correct. Once handed over – throughout the operational life provide an ongoing feedback loop for any aspect of performance.
11. Process is key, this is a useful protol to follow. There is a wealth of information available on the UK mandate for anyone who is interested in finding out more.
12. R&D Title
13. Hi DB BIM LEAD for IES I work in Consultancy & Development at IES delivery projects on a daily basis.
14. BIM – not going into full detail – just want to paint a picture – Its not a software – software's are tools to achieve this along side standards methods and procedures and people This is the information delivery cycle taken from PAS 1192 -2 This is the key to making the process work Considering energy and carbon from the outset of the project and managing /reusing this data to inform design as Sarah has mentioned. All the teams throughout the design & operation cycle have to be involved When it comes to energy and carbon this is vital
15. Geometry setup is still one of the stumbling blocks, Jean will touch in more detail on basic modelling, but I would recommend reading through our white paper. The key is having a full bound building enevelop – no air gaps in your model with spaces/rooms placed throughout your model including stairs/risers/ceiling voids if used IES worked with a client - they had set up the model really well, but still had some issue One of these was the import settings as had been one of their final issues Enhancements – Navigator to help users Improvements to plugin – Bring ABC functionality into the plugin further improvements to algorithims
16. The next thing the client wanted to do was import construction tags/information. So there is a way to do this. So I’ll go through the process and then run a live demo
17. So if you go through this process you can tag multiple constructions Even if you don’t want the thermal properties – you can now easily locate them once in the VE and update them or use them.
18. So what other data and information can we bring across? As Sarah mentioned - gbXML 6 we will be able to do more.
