What is BIM? (Building Information Modeling)

Building Information Modeling (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 modeling. 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 Modeling 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 Modeling 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. 


BSI Building Information Modeling (BIM) Solutions

BSI BIM Verification PAS 1192-2


Verification Certificate

Design & Construction

Capital/Delivery

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.
