Which BIM roles are relevant to your business?

Stroma Certification's BIM Certification scheme offers an independent assessment of an organisation's level of BIM maturity in order to deliver a project in compliance with BIM Level 2 and PAS 1192-2. This assessment looks at a business and determines which of the following BIM roles are being fulfilled.

Lead Supplier

A Lead Supplier is an individual or organisation who is appointed by an Employer (see below). Lead Suppliers are responsible for the coordinated delivery of all design or construction project information. They might also appoint members of a Task Team (multi-disciplinary) as part of their supply chain.

BIM Roles

Lead Suppliers in BIM would typically be a Lead Designer or Lead Contractor. This can include client side consultants, project managers, architects, cost consultants, planners, construction managers and main contractors.

These roles should be part of your consideration, occupying Tier 1 of the supply chain, when deciding if you would be a Lead Supplier.

Task Team

A Task Team is an individual or organisation responsible for the production of a specific design or construction task, which results in a defined output.

Members of the Task Team on a BIM project would be other members of the project’s supply chain who feed information to the Lead Supplier. These subcontractors within the supply chain may be surveyors, other specialist designers, building regulation/other framework compliance services, other consultants, mechanical electrical plumbing (MEP) designers/installers, CDM/health & safety, security consultants and installers (such as communications consultants/installers, structural consultants/fabricators/installers, civils designers/installers and highways consultants/installers). This is by no means an exhaustive list.

When deciding if you make up part of the Task Team, consider whether you are a Tier 2, 3 or 4 supplier and are feeding information back up the supply chain.


Employers are outside of our scope of certification. In PAS 1192-2 the Employer could be the client or the Lead Supplier. Thus if you are the client, you do not need certification, however you may want to become familiar with certification requirements, thus you can understand what your supply chain should be delivering. If you are a Lead Supplier you should be supporting your client as part of the procurement processes and would be classed as an Employer to your supply chain.

Certification to BIM Level 2

When an individual or organisation applies for BIM Certification with Stroma Certification, our expert team will audit your business to determine which of the BIM roles are being carried out. An assessment takes place at one or more locations to ascertain whether your business possesses the required competencies to prove compliance to BIM Level 2 (in line with PAS 1192-2:2013).

By undergoing BIM Certification, your business will also be able to demonstrate compliance with PAS 91:2013 (Section 4.2, Table 8). This means that during a tender or bid process, where BIM Level 2 is a requirement, the necessity for your business to carry out a BIM capability assessment is removed.
