What is Structural Engineering and Why Does It Matter?
Structural engineering is essential for ensuring that buildings, extensions, and renovations remain safe, stable, and compliant with regulations. It focuses on designing structures that can withstand various forces, from everyday use to extreme weather conditions. Without proper structural calculations, buildings may develop weaknesses, leading to costly repairs or even structural failure.
Structural engineers apply physics and mathematics to assess load-bearing capacity, stability, and durability. Their expertise helps prevent issues like subsidence, cracks, or collapse, ensuring that homes and extensions meet building control requirements. Whether it’s a loft conversion, a single-story extension, or a full renovation, structural engineering plays a vital role in keeping the project safe and long-lasting.
