Why are structural drawings and calculations required

The architectural designer will come up with the design of your floor plans and elevations; the structural engineer will design a structure and calculate the structure meaning the size and thickness of your RSJ steels or the size of timbers and grade to support upper levels. Sometimes we refer to these as the 'what' and the 'how' when explaining the relationship between the two processes to our clients. The designs are what you want to achieve from your project; the structural drawings are how they will be achieved. 

Stage One

The Structural Engineer will attend to your property and assess the existing property. Please note that in some cases, the engineers will require parts of walls and ceilings to be removed or ground excavated to determine the structure for accuracy in liaison with building control.

Stage Two

After the assessment, the engineer will take all the measurements and other data gathered from the property. They will then input this information into their systems to develop the design and calculations for the appropriate structure to support your new extension or loft conversion. This usually takes around two weeks to complete.

Stage Three

Structural drawings and calculations are completed and ready to be released. These drawings are essential components for building control, party wall matters, and tendering. Therefore, the contractors will need to see what is explicitly involved in the structure before accurately presenting their costs.
