Structural engineers are an integral part of any build. Whether you’re planning an extension, new build, conversion, or renovation, it’s imperative that you have a structural engineer to make sure that your project is structurally sound.

Below, the team at Cardiff Steels takes a closer look at structural engineers – answering all the important questions. Read on to familiarise yourself with what a structural engineer does, and how you can go about finding one.

The Role of a Structural Engineer

Essentially, a structural engineer is a design professional who has undergone the required training to provide advice and guidance or alterations to the structure of existing buildings, as well as designing structures for new developments, buildings, and extensions. In addition to this, a structural engineer can also oversee a structural inspection.

Inspections are carried out to help identify and find solutions for any structural defects present. Finally, a structural engineer will also make sure that your structural calculations adhere to all regulations – for example, Building Regulations. This is important as you are required to submit these calculations as part of your application to Building Control.

Difference between a Structural Engineer and Architect

Structural engineers collaborate with architects in the design of buildings. The prime focus of a structural engineer is to ensure that a building is constructed to be strong and durable, and the most suitable materials are used for overall structural stability. Whereas an architect is more concerned with the aesthetic design and functionality of a building for the end user. Typically, structural engineers and architects don’t come from the same business.

Scenarios that Require a Structural Engineer

A common question is: when do you need a structural engineer? The answer is that there are many situations where a structural engineer is needed to provide structural calculations and drawings. Structural engineers are a key part of any build, and they work closely with architects and construction professionals during the project. Situations that call for a structural engineer include:

  • Building an extension
  • Loft conversion
  • Removing a chimney breast
  • Knocking down internal walls such as load bearing walls
  • Solar panel fittings
  • Underpinning floors
  • Adding or modifying doors and windows
  • Constructing retaining walls in gardens

Furthermore, a structural engineer can be needed for the diagnosis of structural defects in an existing property. Situations where their services are needed here include signs of subsidence and structural movement, cracking, and a sagging ceiling or roof line. Lastly, a structural engineer might be used by a chartered surveyor for the building survey that takes place when the property is bought. A structural engineer can provide insight and investigate any suspected structural issues.

The Cost of a Structural Engineer

How much a structural engineer costs depends on several factors – none bigger than the size of the project. On average, a structural engineer’s fees will be around £300-£250 for a basic project – for instance, knocking down an internal wall. However, the cost can reach about £5,000 for a large-scale, comprehensive residential project. Structural inspections usually cost around £250 according to average estimates.

How to Find a Structural Engineer

Once you’ve decided you need a structural engineer, it’s time to find out how you can locate one. Finding a structural engineer is usually simple; often, you’ll be able to find one through word of mouth – speaking to your architect or build team and learning who they work with. If you want to find your own engineer though, you can always use a service like Local Surveyors Direct. This is an online directory of local structural engineers in your area.
