The introduction of the Building Safety Act (BSA) has redefined the responsibilities of the Principal Designer, increased the level of accountability and added complexity to their primary role, particularly in the construction of facades.
The role of the Principal Designer has always been central to risk management during the pre-construction phase of projects. However, the BSA has catapulted the role to greater prominence, broadening responsibility with an increased focus on compliance, structural integrity, and fire safety. This heightened scrutiny means that Principal Designers are more reliant than ever on manufacturers to provide tested, transparent data and collaborative technical support, ensuring that compliance is embedded into all projects.
It’s essential that this support begins at the specification stage. At Reynaers, for example, this typically involves the technical team working closely with the Principal Designer at the start of a project to ensure the systems specified are tailored to meet employer requirements, project-specific performance requirements, and regulatory obligations. This technical expertise enables manufacturers to fully support Principal Designers, evaluating products and designs before construction begins to ensure regulatory compliance is built into the fabric of the building, even at the preliminary design stages.
BESPOKE TESTING TO PROVE COMPLIANCE
Where there is not an existing test to cover a particular structural or performance requirement, Reynaers will carry out bespoke testing to ensure full transparency and compliance. We also collaborate with contractors to make sure that compliance, specification and finish are delivered without compromise. This gives Principal Designers the confidence that they are backed by detailed, project-specific technical information.
The BSA makes performance evidence non-negotiable. The Reynaers Technology Centre in Belgium is a purpose-built testing facility that offers a rigorous, robust testing programme involving water tightness, thermal insulation, noise reduction, and air permeability to fully verify product and system performance claims.
This tested data is then made digitally available to customers and stakeholders to share via Reynaers’ proprietary DigiTrace system, a kind of digital product passport designed to hold product and project-specific information and relevant data. This gives all users immediate access to all the shared product data and evidence of compliance, which gives all stakeholders everything they need at each stage and throughout the full lifecycle of the building by scanning a QR code attached to the window, door or curtain wall product.
GOING DIGITAL
Digital tools are set to play an increasingly central role in enabling Principal Designers to meet their BSA obligations. Beyond BIM modelling, Reynaers offers a virtual reality platform called Avalon VR, which creates an immersive 3D environment where building designs can be explored in detail before construction. Using advanced visualisation, specifiers can walk through projects, test design choices, and identify potential risks or clashes early on in a project.
It also facilitates real-time collaboration, performance simulation, and alignment on specification, ensuring the Principal Designer and project team can make informed, compliant decisions while bringing the architectural vision to life. Through Avalon Reynaers can also provide proactive digital support; testing designs virtually, reducing risk and, crucially, costs, which support informed and compliant choices.
The role of the Principal Designer has never carried greater weight but also sees them better positioned to drive up standards across the built environment. However, this cannot be done in isolation. As a responsible manufacturer, Reynaers is setting a benchmark for how the supply chain must step up: delivering tested and transparent data, engineering bespoke technical solutions, embedding digital tools to safeguard the golden thread, and collaborating openly with designers, contractors, and fabricators. www.reynaers.co.uk
