The Construction (Design and Management) Regulations 2015 are a set of regulations with the purpose of ensuring that health and safety issues are properly considered to reduce the risk of harm during the development of a building project.

The regulations were originally introduced in 1994, revised in 2007 and then there was a subsequent revision to them in 2015. One of the significant changes in the 2015 revision was the
replacement of the CDM Co-ordinator role with the new role of CDM Principal Designer.

What Role Does The Principal Designer Fulfill?

The CDM Principal Designer is effectively an organisation or an individual that needs to be appointed by the CLIENT to take control of the pre-construction phase of their project if it involves more than one contractor (or sub-contractor).

Principal designers have a very important role in influencing how potential risks to health and safety are managed throughout the duration of the project and, therefore, the appointment of the
CDM Principal Designer must be made BEFORE the construction phase of the project begins.

The role of the Principal Designer includes planning, managing, monitoring and coordinating health and safety in the pre-construction phase. This includes taking account of all the information
that may affect the design work on the project and ensuring that the information is communicated to all of the designers and contractors.

The role also includes liaison with the Principal Contractor on the project, keeping them informed of any risks that need to be controlled or mitigated during the construction phase in order to eliminate health and safety risks.


WHO is The Principal Designer?

It’s important to focus on the fact that a Principal Designer needs to be appointed on ALL construction projects where there is more than one contractor – this includes domestic construction projects too.

To reinforce the point, it is the duty of the CLIENT to appoint the Principal Designer. If you fail to appoint one then the regulations identify a default position upon who the responsibility falls;

* For domestic projects, where the client has not appointed a Principal Designer in writing, the designer in control of the pre-construction phase of the project is automatically identified as
the Principal Designer;

* For commercial projects, (businesses) where the client has not appointed the Principal Designer, they themselves automatically become the Principal Designer and assume the responsibilities required of the role.
