BIM and The Government Estate - Summary



The seminar was opened by John Lorimer, the Capital Programme Director for Manchester City council. John set the agenda, and gave an overview of Building Information Modelling and Management. Management seemed to be the ‘buzz’ word in the government strategy seminar; everyone is looking at BIM, but the government are also interested in the 6D side of BIM – Facilities / Lifecycle Management.

Just to clarify the different ‘dimensions’ of BIM are:

2D - Something with 2 dimensions (flat)
3D - Something seen in 3 dimensions e.g. width, length and height.
4D - Adding the aspect of Time to a project (phasing/sequencing)
5D - Adding the aspect of Cost to a project (cost estimating)
6D - The aspect of Life Cycle / Facilities Management (owner/FM)

John also made a point that The Centre for Construction Innovation had hosted BIM seminars as far back as 2008.

The view of the Government was next on the agenda, Terry Boniface, the Programme Manager at the Department for Business, Innovation and Skills gave details of the government’s strategy.

Terry referred to the government construction strategy, a document I forwarded on a week or so ago. (this was published by the cabinet office in May 2011) Some of the key statements in that strategy are:

“Government will require fully collaborative 3D BIM as a minimum by 2016”

“A staged plan will be published with mandated milestones”

“This will be a phased process, working closely with industry groups”

“Allow time for industry to prepare for the development of new standards, and for training”

The government are looking to make a 20% saving on future construction projects, and see BIM as part of that process – more efficient tendering, improved coordination, reduced RFI’s, reduced abortive works, etc. The government want “Improvement in cost, value and carbon performance.”

A chart was presented that showed the recommendation made to the government; it consisted of Levels 0 to 3. Level 0 being 2D CAD, Level 3 being fully integrated BIM. The interesting thing is that by 2016 the government are only aiming for Level 2, which is collaboration. I would have thought that to achieve collaboration, you require integration? We integrate the Architecture and Services models into our Structural model as part of the collaboration process….

The next steps involve the publication of a mobilisation plan, which is expected to be published towards the end of July, and the government will be putting together some work packages which the requirements for BIM can be trialled.

The information provided at the seminar was based on a document in the post below titled; Building Information Modelling (BIM) Working Party Strategy Paper, March 2011.

This 107 page document is a recommendation from the Department for Business, Innovation and Skills (BIS) and it is expected that the government strategy will be close to this recommendation.

Laing O’Rourke were next to take the stage, as a contractor, they really have embraced BIM. They employ BIM Engineers who are responsible for linking all the different models together in Navisworks, producing 4D Construction sequences – adding the element of time to the model, so it can sit side by side with the construction programme and at any given moment you can physically see where the project is compared to where it should be.

They are also responsible for 5D scheduling – costing up the project using BIM, and add things like tower cranes into the model so they can see how it will affect surrounding buildings for example.

They also presented a case study along with Ryder Architecture, of Manchester Central Library. Laing O’Rourke used a 3D model for site set out, to liaise with police and local authorities – show them any hazards, etc. and liaise with local businesses, so they could see in 3D what would be happening in the area. A 3D model was also used for a site safety induction video.

BIM was not used on this project until after Laing O’Rourke won the bid, they had the ability to influence the design team to work in a BIM environment, and assisted in up-skilling team members and the client.

Ryder Architecture used 3D Laser Scanning / Point Clouds to build a model of the existing library building, and from there used BIM for collaboration, clash detection, people movement and 4D (Timeline) construction sequencing (using Navisworks.)

This project is still on site, but the feeling is everything is going well to date.

Manchester City Council are looking to “own” this model, so it can be used for Facilities Management (6D.)

The seminar was attended by 83 people from 57 companies ranging from Engineers, Architects and Contractors through to Local Authorities, CAD Resellers and Universities.
