In this video, we explore the essential documentation needed to demonstrate that a façade is safe and well-designed, with a focus on current UK practices following the Building Safety Act. Discover how the new regulatory landscape impacts higher-risk buildings and what documentation we believe is expected to be submitted to the Building Safety Regulator.

In this video, we attempt to help industry professionals navigate through the Gateway 2 process while adhering to the best practices.

Key Topics Covered:

Overview of the Building Safety Act and its implications for façade design.
The Gateway 2 submission process and its impact on project timelines.
The importance of appointing façade specialists early in the design phase.
Key documentation required for façade safety and better performance

⁉️ Gateway 2: What Design Documents Do You Need First? ⁉️

Over the coming months, IAST will release samples of design documentation critical at the pre-construction stage and essential for Gateway 2 submissions.

🧑‍💻👩‍💻 Our Façade Intelligence platform already hosts case studies with annotated drawings, compartmentation plans, and documentation for various façade types. Today, we’re excited to release the Outline Programme for Pre-construction Façade Design in both PDF and XLS formats, available now to IAST members on the Façade Intelligence platform (link below).

We value your input:
👉 Let us know in the comments which documents you’d like us to focus on next.
👉 Share examples of the documents you need.
👉 Tag colleagues who might find this useful and share this video with them!
