Skip to 0 minutes and 0 secondsBIM is important quite simply because the way that the construction industry has worked for certainly the last 50 years, before that it was slightly different but for the last 50 years, has been in a way that collaboration doesn’t happen, doesn’t take place. People tend to work in pockets of isolation and share information, often begrudgingly. So, the whole idea of BIM is that it is a collaborative process where people share information and where people collaborate at the right time, so it is important because it’s actually taking the industry forward. Why is Level 2 important?

Skip to 0 minutes and 0 secondsWell Level 2 is a target basically when we started to work with Level 2 and implement it through the Government programs in 2011, it was prompted by a series of documents or guidelines, which became the Pas 1192 Suite which many of the people listening will be familiar with, but these are purely guidelines of how to implement, what is a wider business process. But it is important to have the guideline because without a guideline, you don’t know, you can’t measure progress, you can’t metricise it in any way, shape, or form. So, the whole idea of Level 2 was to set what we believed were achievable standards for the industry to reach in a reasonable period of time.

Skip to 0 minutes and 0 secondsI think it’s important to have the target, I think there are many inefficiencies within construction that have been there for a long, long time, construction doesn’t like to change. First of all, we need that target there, the target gives us something to work towards, if there was no target, I doubt it would change anything.

Skip to 0 minutes and 0 secondsThe BIM Level 2 is important because we need the likes of the Government to mandate it across their public-funded projects, Galliford Try that’s quite a big proportion of our work and obviously in terms of the inefficiencies, there are so many incidences of bad information management, design just grinding to a halt for various issues, we have poor workmanship at times which is going to cost us money and time, it obviously has an impact then on the client, so all in all, it’s a target really, to improve that information, it gives a better product, it should give a better product, but importantly as well, it gives a thought process to the end user in terms of not just what it’s going to cost them up front, what it is going to cost them to run that building throughout it’s life, throughout it’s journey.

Why is Level 2 the Target for BIM?

In this video you are introduced to David Jellings, a BIM specialist and managing director of BIMobject, and Andy Ashlet a BIM manager with Galliford Try.

David discusses the lack of collaboration within the industry and how BIM could be central to changing this. He also discusses the importance of Level 2 and what prompted its adoption.

Andy highlights the importance of Level 2 as a target for the industry that can be used to drive change within the industry.

BIM Level 2 is ‘distinguished by collaborative working’ (Mcpartland 2018) where all parties use their own 3D CAD models, but not necessarily working on a single, shared model. The collaboration comes in the form of how the information is exchanged between different parties – and is the crucial aspect of this level.

Design information is shared through a common file format, which enables any organisation to be able to combine that data with their own, in order to make a federated BIM model, and to carry out interrogative checks on it.

Hence any CAD software that each party uses must be capable of exporting to one of the common file formats such as IFC (Industry Foundation Class) or COBie (Construction Operations Building Information Exchange)” (McPartland 2018)

Your task

Read section 1.2 of the white paper ‘Autodesk and the UK BIM Level 2 Mandate’ (Autodesk 2016)

Discuss how feasible it is to achieve BIM Level 2 in practice.

If you have experience on projects yourself you might want to share whether implementing BIM Level 2 was feasible on these and whether they would have progressed better if it had been adopted.
