What is BIM?


Building Information Modelling (BIM) is the process of generating & managing building data during its life cycle. BIM uses real time, dynamic modelling software to increase productivity in building design, construction and management.

BIM Levels & Maturity

Level 0

In its simplest form, level 0 effectively means no collaboration. 2D CAD drafting only is utilised, mainly for Production Information (RIBA Plan of Work 2013 stage 4).


Output and distribution is via paper or electronic prints, or a mixture of both. Most of the industry is already well ahead of this now (source: NBS National BIM Report 2014).

Level 1

This typically comprises a mixture of 3D CAD for concept work, and 2D for drafting of statutory approval documentation and Production Information. CAD standards are managed to BS 1192:2007, and electronic sharing of data is carried out from a common data environment (CDE), often managed by the contractor. This is the level at which many organisations are currently operating, although there is no collaboration between different disciplines – each publishes and maintains its own data.

Level 2

This is distinguished by collaborative working – 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 used 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). This is the method of working that has been set as a minimum target by the UK government for all work on public-sector work, by 2016.


Level 3

Currently seen as the holy grail, this represents full collaboration between all disciplines by means of using a single, shared project model which is held in a centralized repository. All parties can access and modify that same model, and the benefit is that it removes the final layer of risk for conflicting information. This is known as ‘Open BIM’. Current nervousness in the industry around issues such as copyright and liability are intended to be resolved – the former by means of robust appointment documents and software originator/read/write permissions, and the latter by shared-risk procurement routes such as partnering. The CIC BIM Protocol makes provision for these.

BIMTek Services

3d Models

BIMTek primarily uses Autodesk REVIT for 3d modelling however we also have capability in Autodesk Inventor when highly detailed components are required. Over the years we have built up an extensive BIM library allowing us to accurately and efficiently develop 3d models. From a master 3d model, drawings of key areas can be produced incredibly quickly. They will also update automatically if the design changes or progresses.


Use your mouse to control the 3D Model to the left.


Using Enscape™ we can produce high quality animations and interactive walkthrough models. We can also use this in conjunction with our Oculus Rift Virtual reality headset. This technology is an engaging and effective tool particularly for stakeholder review workshops or operator reviews especially when compared to traditional 2d drawing review methods.

Asset Identification & Tagging

We can create a system-based register that includes fields to populate:

  • Details of the assets

  • Their location

  • Associated manufacturer’s information

  • Spares and warranty schedules

  • Maintenance regime

  • *customer specific fields*
