What does a structural engineer do?

Whatever your construction project might be, it’s extremely likely that at some point you will need to think about hiring a structural engineer. All building renovations, refurbishments and extensions usually involve some sort of work that could put you, your family or your contractors at risk at one point or another.

Structural engineers are fully trained to ensure the safety of any property and have highly proficient maths and physics skills that enable them to carefully calculate how sturdy and secure such buildings are. They are even available to organise the safe and secure running of a property demolition.

Why do I need to hire a structural engineer?

  • For new builds – structural engineers work on all kinds of residential and commercial projects including designing bridges, tunnels, stadiums, offices, homes and skyscrapers. So whatever kind of property you’re planning to build, make sure you consult with a structural engineer throughout.
  • For refurbishments and extensions – to make your refurbishment safe it’s advisable to hire a structural engineer, especially if the work involves removing fundamental parts of structures such as walls, columns, knocking through doorways or constructing new areas such asbasements.
  • To assess how safe a structure is – you can hire a structural engineer to produce a report of how safe a property is. This is particularly useful if you are buying a new property and could even enable you to negotiate on asking price. On the other hand, if you are selling your property providing a structural report is useful for potential buyers.
  • When demolishing a building – a structural engineer can advise on how to safely demolish whole properties, or specific parts of buildings.

When this is the case, they are called Chartered Engineers.

It is generally considered a good practice to hire a Chartered Engineer, however there are also several Engineers with considerable experience who are not chartered.
