BIM Doctor: Sarah Davidson, head of research and development, Gleeds

Sarah is a Director at Gleeds, heading up their Research & Development department and leading a number of programmes supporting information management and developing service delivery.

She has in excess of 20 years’ project experience in the UK working with a variety of clients on many different build projects in both quantity surveying and project management roles. Latterly her work has focussed on matters surrounding inflation, information modelling and value management both in the UK and overseas.

Sarah’s interest in BIM is primarily concerned with cultural change for BIM, the requirement for a robust BIM framework and the potential to improve efficiency and performance through software optimisation.

Her work leading BIM development within Gleeds has led to appointment by the UK’s Construction Industry Council to be the chair for the East Midlands Regional BIM Hub. Sarah works closely with the Government’s BIM Task Group, raising awareness, capacity and capability for BIM. She is also one of the first RICS Certified BIM Managers in the UK.

Live Q&A with our BIM Doctor - Wednesday June 11, 2014

1:00 - Sarah Davidson:
Welcome to ÐÇ¿Õ´«Ã½â€™s BIM Doctor surgery – my name is Sarah Davidson and I’m here to help. I work at Gleeds leading BIM within the business and am involved in a number of live projects. I also lead the East Midland’s BIM Hub for the CIC, I do a lot of work with the RICS and am an RICS Certified BIM Manager. Please let me have your queries, thoughts and observations about BIM – I’ll try and deal with the questions as they come but please be patient…

Appreciate the opportunity to join as I am in the very early stages of understanding BIM as a fixings supplier to the industry. Can you point me firstly to the best sources of info?

Reply from Sarah Davidson:
PAS 1192-2:2013 is great for establishing the principles of BIM. You should be able to find this through BSI free of charge. As a fixings supplier the thing to think about is what information about your product is important in the design, construction and operation of an asset. It may be that it's a case of presenting information about your fixings in a way that makes the information easy to transfer and use...

I've seen a lot of press about COBIE, but the requirements seem onerous. Do clients really require this? Thanks

Reply from Sarah Davidson:
COBie is a means of getting information from the project information model (that's all the information you to design, then construct and asset) into the asset information model (the information you need to operate and manage the asset). I guess it depends on who the client is but ultimately someone will need to operate and manage the asset whether your client is a developer, tenant etc. On this basis I would say that COBie is a flexible tool, that's freely available to support this. It should also provide for transfer of data into CAFM (computer aided FM) systems. I would expect that as technology and knowledge develops COBie will similarly develop as will other tools that seek to do the same thing

How would you like to see BIM , or its offspring, developing over the next 10 years, and what might prevent it happening

Reply from Sarah Davidson:
A great question! Personally I would like to get to the point where we understand how an asset is going to go together, what it's going to look like, how it's going to perform, when it's going to be ready and how much it's going to cost (to build and run) just like we can when we purchase a car. We should be able to get to this. What will prevent it happening? Possibly, fear of the unknown, cultural barriers, failure to communicate effectively...

Do you think BIM is becoming more widely accepted for refurbishment projects?

Reply from Sarah Davidson:
We are seeing increasing requirements to support refurbishment projects with BIM and I think it will become more widely accepted. It's important to understand how all information is going to be managed and to represent it in the right format that will allow its transition and re-use without generating risk. On this basis BIM can help all project types

Customers, especially in the public sector are pushing the social value agenda and often making it a contract requirement to use a local SME based supply chain. Is it realistic to expect these small firms to invest in understanding BIM when their rates continue to be squeezed? Most I speak to just aren't interested.

Reply from Sarah Davidson:
The investment in understanding and that required to deliver may be different. The starting point for SMEs (and customers!) is to understand the principles of BIM (PAS1192-2). They may find that they require a change in the way they work and provide there information as opposed to big investment in technology. Having said that the idea of technology is to make us better and more efficient in what we do. The benefits should look to outweigh the investment...

Hi Sarah thanks for presenting this helpful service. We too are embarking/evaluating BIM. We manufacture and supply lighting controls for building spaces.We are looking at overseas markets and would like your opinion on how BIM either adapts or standardises in other regions globally. Are there any 'potholes'to look out for ahead? thanks.

Reply from Sarah Davidson:
When you're looking at overseas markets look at their procurement models and things like copyright and intellectual property. Some of the UK principles should in theory adapt but might be scuppered by procurement. Also, if you're considering creating libraries for your product make sure you understand your IP

Hi Sarah, I read in ÐÇ¿Õ´«Ã½ recently that the government might be scrapping the BIM Task Group. I'm a bit worried about this. Do you think BIM is ready to stand alone?

Reply from Sarah Davidson:
Interesting! Many of the public sector frameworks require a degree of BIM capability/expertise plus a commitment to support training/development of project teams. To get on these then you have to be able to support BIM. I think BIM is now ready but a key thing for me is leadership for BIM. It's essential that clients understand how to drive BIM. It might happen without the client drive, but benefits might not be optimised

Hello there - with regard to Ofqual and their extraordinary plans to scrap engineering GSCE/A levels by 2017, how do you feel this would impact on the future study and development of BIM.. surely a grounding in the physical, the nuts and bolts, the actual 'doing' remains essential to the understanding of the subject, along with the ability to think, plan and develop?

Reply from Sarah Davidson:
It is the younger generation that can really bring the construction industry into the 21st century so I'm keen that the industry is effectively supported by education. It is essential that members of teams understand who does what, how construction fits together etc. also, really important that people can communicate effectively. I would like to see more in schools and colleges around the subjects that support construction, not less...

Also with regard to refurbishment - do you think the client is taking ownership of the model earlier and supplying this to consultants and contractors to update or is it still a tendency to expect the contractor and the consultant team to create and supply the model?

Reply from Sarah Davidson:
Might depend on what you mean by 'model' do you mean a model created from point cloud survey data of the existing building

1:39 - Comment From Guest
Customers, especially in the public sector, are pushing the social value agenda and the use of a local SME based supply chain. Can we realistically expect such small firms to invest in BIM when their rates are stile

Reply from Sarah Davidson:
If we remember that BIM is not just about the generation of object based models but also about the management of information then I think SMEs can be persuaded to support BIM. A lot of what BIM is about can be achieved without major investment. Any investment should ultimately offer a return to the SME...

Hi Sarah. What experience do you have of creating BIMs for existing buildings? What would you suggest is the best workflow for capturing the info in the first place.

Reply from Sarah Davidson:
I would suggest the starting point is to consider the life of the building, what the long term plans are for it and whether or not it sits within a portfolio. Once you know this you can determine how and what data you collect about its physical characteristics. If you want to create a digital object based model then a point cloud survey may be required but you'll need to ensure that the model generated from this captures more than just object geometry. You may need to supplement these surveys with further investigation to establish structural characteristics, which may impact on future works to the building.

Have you experience on the legal side, in particular, how is BIM compliance dealt with in an appointment as I don't think it is yet a statutory requirement i
