For any major construction or renovation project, hiring an experienced structural engineer is essential to ensure the integrity of the building. When searching for a local structural engineer on hipages, here’s what you can expect in terms of services and costs.

What does a structural engineer do?

Structural engineers are a type of building consultant and are an important part of the building or renovating process. As they are responsible for the structural integrity of a building, these engineers design and specify the structural components like walls, foundations, footings, posts, beams and more.

Structural engineers typically perform the following tasks:

• Design the framework of buildings and other structures to ensure strength and rigidity.
• Study the development of new building materials and building methods.
• Consult with other engineers, architects, landscape architects and environmental scientists.
• Operate and program computers to assist with calculations.
• Research, develop and test solutions to specific structural problems.
• Supervise construction of buildings and make recommendations for corrections if there are any problems or if the building doesn’t meet standards.
• Take into account the effect of natural forces on the building’s design (e.g. strong winds and storms).
• Review existing structural designs to identify savings or to match the building closer to the builder’s expertise.
• Pre-purchase inspection reports.
• Identify the feasibility of removing or moving load-bearing walls or other structures.
• Provide advice on how to safely change the layout of an existing home (if required).
• Organise delivery of the materials and equipment needed to complete the project and supervise the labour.

What are the most common types of tools used by structural engineers?

Structural engineers use various tools to ensure buildings are safe, durable and meet the prescribed design requirements. Here are some of the more common tools used by structural engineers in Australia:

Computer-aided design (CAD) software

Structural engineers use CAD software to create detailed 3D models of buildings. This type of specialised software allows them to visualise and analyse the behaviour of structures under different loading conditions.

Structural analysis software

Structural analysis software can be used to determine the strength and stability of different structures. Engineers will use it to simulate different types of loads, such as wind and earthquake, and predict how the structures will react under these conditions.

Finite element analysis (FEA) software

FEA software is used to model complex structures and simulate their behaviour under different conditions. It allows engineers to analyse the stresses and strains in any given structure, and determine whether it can actually withstand the loads it will be subjected to.

Drawing tools

Many structural engineers – particularly those who have been in the profession for decades – will still use common drawing tools, such as pencils, pens, rulers and compasses, to create sketches, diagrams and plans for their projects. These tools are essential for communicating design ideas and details to architects, builders and other key stakeholders.

Testing equipment

From load cells to strain gauges to accelerometers and more, structural engineers will use different testing equipment to measure the performance of structures under different conditions. This equipment is used to help ensure the structure is safe and will meet specific performance criteria.

What type of projects can you hire a structural engineer for?

Structural engineers are typically hired for projects that involve designing, analysing and constructing buildings that support or resist loads. Some common projects that require the services of a structural engineer include:

• Building design: Structural engineers are often involved in the design of buildings, including commercial, residential and industrial structures. They ensure that buildings are safe, durable and able to withstand the loads they will be subjected to.
• Retaining walls and foundations: Structural engineers design retaining walls and foundations for buildings, roads and other types of structures. They ensure these things are able to support the weight of the building or road, as well as resist external loads like soil pressure.
• Structural repairs: Often structural engineers are hired for projects that involve repairing or strengthening existing structures, particularly those that have been damaged by natural disasters or years-long deterioration.
• Bridge design: Some structural engineers are also involved in the design of bridges. They ensure that bridges are safe, structurally sound and able to withstand heavy traffic loads and turbulent weather conditions.

How much does a structural engineer cost?

The cost of hiring a structural engineer in Australia can vary depending on several factors such as the complexity of the project, the level of experience of the engineer and where the project is taking place. According to Effective Building and Consultancy, the hourly rate for hiring a structural engineer is around $60 to $100 per hour, with a typical inspection taking anywhere from one to three hours.

For a forensic structural engineering report, ANZ Engineers suggests that the hourly rate starts at $150 but can increase to $450 per hour. You can expect to pay around $990 for a preliminary report with no research, up to $2,390 or more for a full forensic report.

For a complete residential or commercial construction project, you should speak to your preferred engineer and get a quote for the full job upfront, as this will give you an idea of total costs as well as any hidden fees.

In addition to the hourly rate, structural engineers may also charge additional fees for services such as site visits, reports and project management. It's important to request a detailed quote from the engineer before hiring them to ensure you are aware of all the costs associated with your project.

What to ask when hiring a local structural engineer

When hiring a local structural engineer, it's important to ask a few key questions to get a sense of their experience levels and aptitude for the job. You might want to ask them:

• What qualifications do you have and how long have you worked as a structural engineer?
• What are some of the recent projects you’ve worked on?
• What’s your approach to structural analysis and design?
• Are you familiar with the local building codes and regulations?
• Are you registered with the relevant licensing authority?
• How much will this project cost in full?
• Can you provide references from past projects?
