This level of BIM maturity is very much about better information management and establishes the methodology for managing the production, distribution and quality of construction information. This include information generated by CAD systems, using a disciplined process for collaboration and a specified/consistent naming policy.

BIM Level 1 maturity is illustrated in the Bew-Richards “BIM Wedge” below and its requirement for "file based collaboration"

The key BIM related standard for BIM Level 1 maturity is BS 1192:2007 + A2:2016: Collaborative production of architectural, engineering and construction information. Code of practice.

Many projects currently adopt the principles and ways of working required for BIM Level 1. To achieve the BIM Level 1 standard, the following elements should be in place:

  • Roles and responsibilities should be agreed upon.
  • Naming conventions should be adopted.
  • Arrangements should be put in place to create and maintain the project specific codes and project spatial co-ordination.
  • A "Common Data Environment" (CDE) for example a project extranet or electronic document management system (EDMS) should be adopted, to allow information to be shared between all members of the project team,
  • A suitable information hierarchy should be agreed which supports the concepts of the CDE and the document repository.

The establishment and effective management of the CDE is key to this standard.

The employer should also set out a requirement for BS 7000-4:2013 Design management systems. Part 4. Guide to managing design in construction. Key features of this standard include:

  1. A framework for design management: This includes the formation and management of the design team, responsibilities, establishing the brief, project planning, process planning, programming, classification, project communications and costs to the client/employer.
  2. Design resource management: This includes staff resource, innovation and value management (VM), technical information, manual, CAD and BIM production, records management, and technical equipment, procuring design, surveying and other related services, extracting data requirements, intellectual property and copyright.
  3. Design process management: This includes re-commission review, design brief, design stages, progress validation, design data control, design during construction, monitoring during construction, testing, completion, post occupancy and design management appraisal.
  4. BS 8541-2:2011 Library objects for architecture, engineering and construction. Recommended 2D symbols of building elements for use in building information modelling is another supporting standard however these are generally aimed at design organisations as opposed to an explicit employer requirement.

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. For further information in how to deliver BIM Level 1 compliant projects, please refer to the BIM Level 1 guidance.
