Local CDM Context

Pre-construction safety planning in St John's Wood NW8

Appointing a Principal Designer for works to a St John's Wood building is a legal duty where more than one contractor is involved or reasonably foreseeable. In practice, coordinated design-risk and buildability decisions aim to reduce avoidable surprises, variations and stoppages.

Pre-construction information is the role's backbone: surveys, asbestos registers, structural records and service routes for the St John's Wood building assembled so contractors price the real project rather than discovering it.

We coordinate, the designers design: the Principal Designer role manages the process and the information flow, and where structural or specialist design input is needed on a St John's Wood project we confirm scope and competence and bring the right discipline in.
