This level of BIM maturity is very much about better information management and establishes the methodology for managing the production, distribution and quality of construciton information. This includes information generated by CAD system, using disciplined process for collaboration and consistent naming policy. Building Information Modelling [BIM] Level 1 has been defined by the SFT BIM Delivery Group and the Home Nations Working Group as:
“BIM Level 1 maturity encompasses the management of digital, indexed construction information, including that generated by 2 or 3D CAD systems within a common data environment. Disciplined design and information management policies for collaboration and a specified naming policy shall be used. Appropriate and proportionate measures will be applied to manage the security risks that affect a built asset, asset data and information.”
BIM Level 1 maturity is illustrated in the Bew-Richards "BIM Wedge" below and its requirements for "file-based collaboration" using a Common Data Environment (CDE). 



The BIM Level 1 process is underpinned by a series of standards developed by BSI. The BIM Delivery Group for Scotland believes BIM Level 1 provides an invaluable platform to deliver change both in terms of implementing BIM and emphasising the value of information management.
Following consultation the BIM Delivery Group have elected that other than the BS 8541 series all the following standards will be required and optional on a BIM Level 1 project as determined through the SFT BIM Grading tool:

BIM Level 1 Required Standards

  • BS 1192:2007 + A2:2016 Collaborative production of architectural, engineering and construction information. Code of practice
  • BS 8536-1:2015 Briefing for design and construction. Code of practice for facilities management (Buildings infrastructure)
  • BS 8536-2:2016 Briefing for design and construction. Code of practice for asset management (Linear and geographical infrastructure)
  • PAS 1192-5:2015 Specification for security-minded building information modelling, digital built environments and smart asset management
  • BS 7000-4:2013 Design management systems. Guide to managing design in construction

BIM Level 1 Optional Standards

  • BS 1192-4:2015 Collaborative production of information Part 4: Fulfilling employer’s information exchange requirements using COBie – Code of practice
  • PAS 1192-6: 2018 Specification for collaborative sharing and use of structured Health and Safety information using BIM
At the heart of the BIM Level 1 process are the principles established in BS 1192:2007 for collaboration using standard methods and procedures such as a common data environment (CDE) approach, defined naming conventions and a data exchange plan. This standard is seen as mandatory in a BIM Level 1 environment.

Having an effective CDE system and approach is key to BIM Level 1. Whilst other standards such as BS 8536 and PAS 1192-5 assume the use of BIM Level 2 their principles can be equally applied to a BIM Level 1 environment and SFT have adopted this position.
The BIM level 1 standard is being adopted in various ways within exisiting projects. Procuring Authorities are recommended to familiarise themselves with the related standard BS 1192:2007 + A2:2016: Collaborative production of architectural, engineering and construction information code of practice. This will identified areas that may require further review to deliver BIM Level 1 compliant projects.
