BIM Level 2

So what’s this BIM Level 2 thing all about then!

BIM Level 2 is the mandatory level of project collaboration required for public sector works in the UK from April 4th 2016 and is also a steadily growing deliverable target within the private sector.

In the UK [and accepted generally in Europe] the objective BIM process is laid out in a suite of 8 interlinked documents, standards & protocols [often referred to as the ‘8 Pillars of BIM’] – known as UK BIM Level 2 – which are in turn built on a foundation standard for collaborative working:

Foundation Standard

  • BS 1192:2007+A2:2016 – Collaborative production of architectural, engineering and construction information. Code of practice

    • This standard establishes a common, collaborative approach for production, naming and management of construction information.
    • This is the foundation standard upon which BIM Level 2 is developed. Cementing the principles of BS 1192:2007+A1:2015 into your internal working practices is the platform from which cross-discipline collaboration and BIM workflows grow.

BIM Level 2 ‘Pillars’

  • PAS 1192-2:2013 – Specification for information management for the capital/delivery phase of construction projects using building information modelling

    • This standard establishes a common, collaborative approach for co-ordinating & managing design & construction information during the capital (CAPEX) phase of a built asset. PAS 1192-2 describes how information is developed, managed and delivered between project stakeholders and project team personnel during design and construction of the asset.
  • PAS 1192-3:2014 – Specification for information management for the operational phase of assets using building information modelling

    • This standard establishes a common, collaborative approach for Management of Asset Information during the operational (OPEX) phase of a built asset. Whilst this standard covers management of the asset and information post-construction, this standard also acts as a precursor to design and construction activities under PAS 1192-2 ensuring that the information the client needs to operate the asset is requested and delivered during the design and construction phases.
  • BS 1192-4:2014 – Collaborative production of information. Fulfilling employer’s information exchange requirements using COBie. Code of practice

    • This standard establishes a common structure for Construction Operations Building information exchange [COBie]. COBie is a structured set of data about the built asset in a non-graphical format which is essential for Facilities Management. COBie is often delivered along with an IFC model which is an open graphical exchange format – COBie is essentially a non-graphical descriptive sub-set of modelled data. COBie is an open exchange format independent of any proprietary software and is commonly accessed as a spreadsheet.
  • PAS 1192-5:2015 – Specification for security-minded building information modelling, digital built environments and smart asset management

    • This standard establishes principles for the integrity and secure access, development, management and storage of built asset information. It also describes how information pertaining to projects involving sensitive data should be managed.
  • BIM Protocol

    • This is a supplementary and addendum protocol to standard construction contracts which forms a legal agreement between parties on projects using BIM. Effectively, this protocol adds an obligation to the main contract for each party to supply information which allows for the production of Building Information Models and sets in place BIM deliverable requirements and dates.
  • Government Soft Landings [GSL]

    • Government Soft Landings is a framework which ensures value is achieved in the operational phase of a built asset after construction. Soft Landings puts in place a smooth transition process from construction phase to use of a built asset to ensure the building performs to the standard it was designed and intended. This is particularly important process for handover and fine-tuning of MEP equipment and plant to ensure optimal performance of the building services. Essentially, Soft Landings facilitates an enhanced ‘after-sales service’ alongside traditional defects liability and warranty periods. Check out this article on NBS for a succinct overview of Government Soft Landings.
  • Classification

    • Classification is a standardised system allowing construction information to be indexed & structured in a common format across sectors and disciplines within the industry. Standardised classification of items within built assets facilitates quick, consistent & accurate searching, referencing and auditing of information for activities such as costing, CAD layering and specifications.
  • BIM Toolkit [Digital Plan of Works]

    • The NBS BIM Toolkit is a free resource which functions as a Digital Plan of Works management platform for public and private sector projects using BIM. It provides step-by-step help to define, manage and validate responsibility for information development and delivery at each stage of the asset lifecycle.

BIM Enablers

Alongside the UK BIM Level 2 standards, there are also a plethora of BIM guidance tools and enablers available which help to understand and implement BIM into working practices. Some of our favourites include:

BIM Level 2 Websites

  • From 4th April 2016, a BIM Level 2 website will be available at providing guidance and documentation to support the industry.
  • The BIM Task Group and BIM Regions websites are also invaluable resources for BIM advice and guidance along with our own community forum here at

BIM Delivery Cube

The BIM Delivery cube is an innovative communication matrix that links Work Stages, Stakeholders and Delivery Components together to offer BIM guidance and understanding to project stakeholders throughout the various stages of a project.

CPIx Protocol

The CPIx Protocol is a suite of assessment forms along with a template BIM Execution Plan. The assessment forms are an invaluable basis for assessing BIM capabilities across the supply-chain when forming a team to tender for the supply of Building Information Modelling. The BIM Execution Plan describes how the chosen team intends to deliver Building Information Modelling as part of the tender documentation to the client.

CIC Best-Practice Guides

The Construction Industry Council have published a number of useful guides and reports to help assist implementation of BIM within the industry including:

  • Best Practice Guide for Professional Indemnity Insurance when using BIM
  • Outline Scope of Services for the role of Information Management
