Structural Engineer Design and Calculations 

What is structural engineer design and calculations?

Structural drawings for the structural engineer are a set of designs and calculations that will present how the loft conversion, home extension or new build will be constructed. 

The design would be detailed as per what type of timbers to use, thickness of the steels, type of concrete to be used, is a slab or block and beam floor, what type of steel connections to be used and more..

Our structural engineers would attend your property and survey the property in order to produce structural design and calculation for your project.

Why do I need structural engineer?

These drawings are used for builder costings, party wall agreements, building control approvals, building control inspectors and by your insurance company.
