Information Management Matters Now More Than Ever

This role is often confused with the Principal Designer under the CDM Regulations, but the two roles are very different. While the CDM Principal Designer focuses primarily on managing health and safety risks during the design process, the Principal Designer under Building Regulations maintains a far broader and more demanding responsibility.

In simple terms, the PDBR must ensure that, if constructed as designed, the building will comply with all relevant building regulations. Despite the simple role description, those in this position bear considerable influence.

Unlike some aspects of the Building Safety Act, the PDBR role applies to all building projects, not just higher-risk buildings. This remains a common misunderstanding across the sector. The intention behind the PDBR is to establish defined accountability for design compliance, and to ensure that someone takes ownership of verifying that regulatory requirements have been properly considered and coordinated across the entire design. However, this clarity of responsibility brings new problems to light, particularly in modern procure-ment environments.

In traditional design-and-build procurement, design responsibility is often fragmented. While the lead designer may show a particular system or material at the planning stage, detailed decisions are frequently made later by specialist subcontractors during construction. Cladding systems, fire stopping solutions, service penetrations, and façade components are often finalised after contracts are awarded.

Historically, these evolving design decisions have not always been fully coordinated or visible to the wider project team. Under the new regulatory framework, a lack of transparency is no longer acceptable. The PDBR must be confident not only that a regulatory design exists, but also that any changes made during procurement and construc-tion also remain compliant. This is fundamentally an information management matter, as much as it is a design one.

This is where digital information management and the role of BIM technologies have become increasingly critical. A coordinated digital model provides something the industry has rarely seen before: a single environment where architecture, structure, building services and specialist design elements can be viewed together. This enables the PDBR to consider a building as an integrated system rather than as isolated drawings produced by different disciplines.

Visibility is essential. Compliance cannot be assured if design information is fragmented, inconsistent, or hidden within disconnected documentation. Digital workflows also underpin the Golden Thread of information, ensuring that decisions made during the design process can be tracked through construction and into the building’s operational life. As regulatory expectations increase, the ability to demonstrate compliance through structured, trace-able information is becoming just as integral as the design itself.

One area where this new approach is imperative is in the coordination of builders’ work openings and fire stopping. Historically, this has been one of the most poorly managed aspects of building design and construction. Openings for services have often been created on site in an extemporaneous manner, with little coordination between designers and contractors. Responsibility for specifying and installing fire-stopping solutions has frequently been obscure, with decisions sometimes driven by cost rather than performance.

The result has too often been incomplete or incorrectly installed fire protection, posing perilous risks to life and safety. Under the Building Safety Act, the PDBR must now have confidence that these elements are properly designed, coordinated, and tested for compliancy. This requires a level of clarity and traceability that traditional processes cannot provide.
