FAQ's
What does a structural engineer do?
A structural engineer is responsible for the design of a building or structure, providing the calculations and drawings relevant to assure structural integrity throughout construction and life cycle. This ensures buildings and structures are safely built and comply with Part A of the Building Regulations.
Do I need a structural engineer for my home project?
If construction work is proposed in a project, involving altering the existing structure, adding significant loads or building a new structure, then you will need a structural engineer. If you are unsure whether the alterations are structural (such as whether a wall is load bearing or if removing a chimney has structural implications) then you will also need advice from a structural engineer.
Why do I need structural calculations for my project?
If construction work is proposed in a project, involving altering the existing structure, adding significant loads or building a new structure, then you will need structural calculations. These calculations and drawings will need to be produced by a qualified structural engineer in order to comply with building regulations and other statutory regulations. Not all projects require calculations, but it is recommended that you speak to an engineer to seek advice.
When would I need a Structural Engineer?
It is recommended to engage with a structural engineer as well as an architect at building control design stage, well ahead of construction. In other cases, particularly for new builds or basement conversions, a structural engineer might be required to carry out a feasibility study before submitting a planning application. The architect can also advise the client on when a structural engineer is required.
Do you produce safe designs, accurate drawings and calculations?
Yes, each design is tailored to meet your project’s requirements, following a site inspection. We take into account relevant design codes, building regulations and CDM regulations.
