Why Are Structural Drawings and Calculations Required?

While the architectural designer focuses on creating the floor plans and elevations, it is the role of the structural engineer to determine how the structure will be built. They design the framework—calculating elements such as the size and thickness of steels or the grade and size of timbers required to support upper levels. In simple terms, the architectural designs represent what you want to achieve, while the structural drawings explain how it will be achieved.

Structural drawings and calculations are crucial because they ensure your project is not only aesthetically pleasing but also safe, compliant, and structurally sound. These detailed plans are essential for building control approval and allow contractors to price the project accurately.

Our Three-Step Structural Process

Stage One: Property Assessment
A structural engineer will visit the property to assess its current condition. In some cases, parts of walls or ceilings may need to be removed or the ground excavated for an accurate evaluation. This step is essential to gather precise information in coordination with building control.

Stage Two: Structural Design and Calculations
Using the data gathered, the structural engineer will develop calculations and designs for your new extension or loft conversion. Ensuring that the structure can safely support the new alterations.

Stage Three: Finalized Drawings and Calculations
Once completed, the structural drawings and calculations are provided. These documents are vital for building control approval, resolving party wall matters, and for contractors to assess costs accurately. They give a clear picture of the structural elements required for your project, ensuring everything is built to the highest standards.
