A principal designer oversees the pre-construction phase of a multi-team project. Appointed by the client directly, the role of the principal designer is varied. Aside from initially assessing the health and safety requirements of the task ahead, they act as the glue that holds the entire team together-working closely with other designers and contractors, they co-ordinate the work required and make sure everyone knows what they are supposed to be doing.
The work of a principal designer must also conform to the Construction (Design and Management) Regulations 2015, produced by HSE. The Construction (Design and Management) Regulations are the main set of regulations for managing health, safety and welfare of construction projects. CDM applies to all building and construction work and includes new build, demolition, refurbishment, extensions, conversions, repair and maintenance.
