How does building information modelling (BIM) affect the process of designing built assets? Casey Rutland, Associate Director at Arup Associates, explains in this excellent eight minute video.

“This isn’t about software or clients having to ask for something” says Casey. “It’s about digitising the whole industry …and it’s a massive task”. Over the course of his presentation, delivered at the London + South East BIM Region event in autumn 2015, Casey explains the impact BIM will have on the industry and in particular the process of built asset design. He focuses on six key areas:

1. Reduced Waste – BIM streamlines the process of design and delivery helping to reduce the high levels of waste found in conventional approaches. “It’s not just about eliminating waste in what we build, but how we build it; reducing time, money and carbon” says Casey.

2. Improved Visibility – the BIM process allows people to see things much earlier on in the project lifecycle. The 3D laser scan that was undertaken by Arup Associates at Broadgate Circus, enabled a full and highly accurate section to be quickly created at the outset of the project.

3. Greater Confidence – The three-dimensional nature of graphical information in a BIM environment (together with the well-structured attribute data linked to it) enables designers to become more confident around their proposals. They can display and communicate their designs with greater clarity, passing confidence on to their clients.

4. Better Communication – That same three-dimensional information enables better communication between project teams, their employers and the built assets end users. Casey points-out that: “there are very few people outside the industry who can take a 2D plan and consider it three dimensionally in their mind”.

5. Greater Understanding – BIM brings each discipline within the design process much closer together, enabling them to visualise and review things with increased speed and better alignment. Casey highlights how such an approach can streamline the process with the ‘Believe in Better Building’ recently procured by BskyB; the multi-award winning project went from client instruction to completion in less than 12 months.

6. Improved Efficiency – “From a fundamental level using a piece of software – not saying that’s BIM at all – you can have the same number of people doing more projects” explains Casey. “This is why I don’t believe it when people say the return on investment (ROI) isn’t there, because I can do more projects with the same number of people”.

Casey goes on to highlight the excellent collection of BIM standards available in the United Kingdom (UK) and how transferrable these are to other markets. They are the framework for clear appointments, structured workflows, validation and data exchange in a digital environment. The tools worked particularly well on the £600M Singapore National Stadium and Sports Hub project, completed by an Arup-led team in 2014.

He ends with a look at ‘Project Ove’; an Arup funded trial project that sought to demonstrate and test BIM capabilities both in-house and with a number of external project team parties: “It’s 13 times more expensive than the Harrods Perfume Hall and is completely unbuildable, but it’s an example of what you can do with the software” he adds.

Casey leaves us with one powerful point: “If you work in this industry and you think this doesn’t apply to you, you’re wrong. It affects every single person throughout the process of designing and delivering built infrastructure”.
