Collaborative Specification: How Working with the Right Supplier Mitigates Gateway Delays

As the Building Safety Act continues to reshape the construction landscape, architects face growing pressure to ensure every element of their design is compliant, documented, and defensible, especially at Gateway Two.

For many, the frustration isn’t the legislation itself but the added complexity and delays it brings when specification, procurement and compliance teams aren’t aligned early enough. But one key change can improve that: collaborative specification with the right supplier from day one.

What Is Gateway Two – and Why Is It a Bottleneck?

Gateway Two is the critical design stage approval point where duty holders must demonstrate how their design meets functional requirements under building regulations. If product specification is vague or incomplete, or if substitutions are made late in the game, the process stalls.

Delays at this stage aren’t just costly, they’re reputational. That’s why design teams are under pressure to get it right, and from the start.

How the Right Supplier Partnership Speeds Things Up

Working with a supplier like Benx, with extensive technical knowledge, a full building envelope offering, and a proven track record of Gateway-compliant systems, can significantly reduce risk and streamline approvals.

Here’s how:

  1. Early Design Involvement Reduces Late-Stage Changes

We work with architects during RIBA stages 2–4 to ensure that the products you specify are not only aesthetically and performance aligned, but also certifiably compliant. That means less rework, and no nasty surprises later.

  1. Certified Systems Remove Ambiguity

From rainscreens to through-wall solutions, we offer certified systems that come with the technical data, fire testing, and performance documentation required to satisfy regulators at Gateway Two. We help create a clear, auditable trail from intent to specification.

  1. Support with Detail Drawings and Specifications

We provide CAD details, BIM objects, and tailored specification support to make your design process smoother. Our team collaborates to resolve interface challenges between products – especially in multi-material façades.

  1. Product Transparency and Substitution Protection

We proactively provide all the data you need to justify your choices. By working closely with your project team, we also help protect the specification from contractor-led substitutions that can cause delays or non-compliance issues.

Why Collaboration Matters Now More Than Ever

Sam Spencer, Benx Specification Manager says “In an era where every material decision must now withstand greater scrutiny, choosing the right partners is no longer a preference, it’s a necessity. The best suppliers don’t just sell products; they enable compliant, creative, and constructible designs. At Benx, we’ve supported architects and design teams across the UK through successful Gateway Two submissions by ensuring our systems deliver on all fronts – performance, aesthetics, and compliance.”
