When it comes to construction and infrastructure projects, structural engineers and civil engineers often work together, but their roles and specialisations differ significantly. Understanding these differences is essential for choosing the right professional for your project. We’ve broken down the key differences across areas of specialisation, the project focus of each specialty, and provided a guide on when to hire a structural engineer or a civil engineer.
A structural engineer focuses on designing and ensuring the safety of buildings, homes, and other structures, making sure they can withstand forces like wind and earthquakes. A civil engineer works on larger infrastructure projects, such as roads, water systems, and public utilities, ensuring they are efficient, safe, and sustainable.
At Vision Structures, we specialise in providing structural engineering guidance for clients looking to alter or add to their existing property, build completely new structures, and provide overall project management for building projects. We make sure that your project is built to last and can withstand an array of forces.
Who Should You Hire?
When to Hire a Structural Engineer
Structural engineers are the go-to professionals for any project involving the physical design and integrity of a structure. They ensure that a building or infrastructure can withstand all physical forces it may encounter during its lifespan.
Real-World Examples:
Retaining Walls: Vision Structures will guide you through the types of retaining walls available, recommend the best option for your situation, design and specify the footings and wall components to ensure the wall can withstand heavy earth pressures. We also confirm that the construction aligns with provided specifications.
New Houses: Vision Structures designs the foundations, floors, walls, roof, columns, and beams to ensure a house remains stable against the forces it will face throughout its lifecycle.
Strengthening Roof Framing for Solar Panels: Vision Structures can assess existing roof framing to determine if it can support the additional weight of solar panels. If the roof framing is not suitable, we provide specifications to strengthen it.
Key Tasks:
Designing load-bearing components (e.g., beams, columns, foundations)
Conducting structural analysis to test the building’s response to different forces (wind, earthquakes, snow)
Working closely with architects to make sure the design is both functional and safe.
When to Hire a Civil Engineer
Civil engineers handle public infrastructure projects, ensuring that the systems we rely on every day (e.g., roads, water systems) are efficient, safe, and sustainable. They focus on the overall systems that support urban and rural development.
Real-World Examples:
Road Networks: A civil engineer will design the layout of roads, highways, and intersections to optimise traffic flow while meeting safety and environmental standards.
Water Supply Systems: Civil engineers plan and maintain water treatment facilities, reservoirs, and pipelines to ensure a steady water supply to communities.
Key Tasks:
Designing and maintaining infrastructure systems (e.g., roads, drainage, water supply)
Ensuring public safety and environmental compliance in large-scale projects
Overseeing project management for urban planning, construction, and government projects
Case Study: When to Choose a Structural vs Civil Engineer
To better understand the differences, let’s look at a real-world example of when you might need either a structural engineer or a civil engineer:
Scenario: New Residential Development
Role of the Structural Engineer: The structural engineer would design and analyse the load-bearing aspects of each house, including foundations, roofs, and walls.
Role of the Civil Engineer: The civil engineer would oversee the planning and construction of the road system, stormwater management, and land grading to ensure proper drainage and water flow.
FAQs: Common Questions About Structural and Civil Engineering
Q: Can a structural engineer also work as a civil engineer?
A: Some structural engineers have a civil engineering background, but they typically specialise in structural design. Civil engineers, on the other hand, work on a broader range of projects, including transportation systems, water management, and urban planning.
Q: What types of projects need a structural engineer?
A: Structural engineers are needed for projects that involve the design and analysis of buildings, roofs, walls, pillars and columns, and other load-bearing structures.
Q: What kinds of projects need a civil engineer?
A: Civil engineers are needed for projects involving large-scale infrastructure like roads, highways, airports, bridges, water supply systems, sewage systems, and stormwater management. They focus on the overall functionality of these systems and ensure they are sustainable, safe, and efficient.
Q: If I’m building a house, do I need a structural engineer or a civil engineer?
A: A structural engineer is essential when building a new home. They’ll work closely with you and the architect to ensure your design can be safely constructed. The engineer will create detailed calculations and plans to support the project. If you're working with an architect, they'll typically handle communication with the structural engineer to keep things streamlined.
Q: I am interested in changing a wall in my current property, do I need a structural engineer or a civil engineer?
A: If you're making major changes to your home, such as removing walls for an open floor plan or adding an extension, you'll need a structural engineer.
