What is BIM? (Building Information Modelling)

Building Information Modelling (BIM) is the management of information through the whole life cycle of a built asset, from initial design all the way through to construction, maintaining and finally de-commissioning, through the use of digital Modelling. BIM is all about collaboration - between engineers, owners, architects and contractors in a three dimensional virtual construction environment (common data environment), and it shares information across these disciplines. 

Building Information Modelling allows design and construction teams to communicate about design and coordinate information across different levels that has been unseen before. This information remains with the project, from before beginning construction, right throughout its lifetime. It also helps to analyze any potential impacts.

Since April 2016, the UK government has required construction suppliers tendering for centrally-procured government projects, including buildings and infrastructure, to be working at BIM Level 2. BSI is supporting the industry with a range of solutions to address the BIM level 2 requirements.

What are the benefits?

Through the use of Building Information Modelling and BIM certification, the following key benefits can be gained:

  • Faster and efficient processes
  • Increased productivity and speeds up delivery
  • Reduced uncertainty
  • Controlled whole-life costs and environmental data
  • Avoidance of rework costs
  • Improved safety
  • Opportunity to secure Government contracts and meet BIM Level 2
  • Reduced on-site waste
  • Prevention of errors

The value of BIM

Learn the benefits that Balfour Beatty, Bechtel and VolkerFitzpatrick gained from achieving verification certification for PAS 1192-2:2013 (Design & Construction Phase). Understand why BIM is critically important to the construction industry and how it helps to underpin commercial opportunities for public and private projects. 

What is the BSI Kitemark for Building Information Modelling (BIM)?

The BSI Kitemark for BIM (Building Information Modelling) is now available.

Achieving the BSI Kitemark for BIM will help organizations in the construction industry demonstrate they are able to deliver BIM projects at the Design & Construction phase (PAS 1192-2). This builds on the BSI verification scheme which gives organizations the evidence they need to prove their BIM capability In a competitive marketplace, with governments around the world starting to make BIM a condition of contact, the BSI Kitemark for BIM gives organizations delivering BIM projects the opportunity to differentiate themselves and prove their credentials in relation to PAS 1192-2. Developed with both Tier 1 and non-Tier 1 organizations in mind, the BSI Kitemark for BIM will provide the most robust measurement of a company’s delivery of BIM projects, certifying their diligence in design and construction, supply chain management, and delivery of customer service excellence. To achieve and maintain the BSI Kitemark, organizations will be routinely assessed by BSI, providing their clients with complete confidence in their delivery to industry standards.

BSI BIM Verification PAS 1192-2

Verification Certificate

Design & Construction


BIM PAS 1192-2

Developed for any contractor involved in using BIM to deliver new buildings or infrastructure projects. It will help you to demonstrate your capability to meet the requirements of one of the BIM standards, known as PAS 1192-2 through meeting independent and impartial third party verification.

The BSI Verification service for BIM has been developed for;

Tier 1 Main Contractor

(These are contractors and/or lead designers with a direct commercial relationship with the client.)

Verification will require evidence of the main contractor’s capability to adopt processes identified in PAS 1192-2.

Tier 2 Sub-contractors and suppliers

(These will typically have a direct contract with the Tier 1 main contractor.)

Verification for Tier 2 sub-contractors and suppliers offers evidence of the sub contractor’s capability to work adopting processes identified in PAS 1192-2, in order to be eligible to supply the main contractor services as part of the supply chain for Level 2 BIM mandated projects.

Tier 3 or 4 Sub-contractors and suppliers

(This group includes specialist contractors, sub-contractors and suppliers working for sub contractors.) Verification offers evidence of the Tier 3 sub contractor’s capability to work adopting processes identified in PAS 1192-2, in order to be eligible to supply Tier 2 services as part of the supply chain for Level 2 BIM certification mandated projects.
