A concrete foundation for a new building is usually designed by the project’s design professionals, such as an engineer, architect or building designer, based on the structure, its loads and the site conditions. The concrete contractor then builds the foundation according to those approved plans and the codes that apply.
Many property owners assume the person pouring the concrete decides how the foundation should be built. On most projects, several people play a part, and each has a different job.
The Roles Involved in Foundation Design
Who is involved depends on the size and type of the project. A simple project may rely on standard plans, while a larger or more complex building may need a custom design. People who may be involved include:
- an architect or building designer who plans the structure,
- a structural engineer who designs how loads reach the ground,
- a geotechnical engineer who studies the soil when needed, and
- the local building department, which reviews plans and inspects work where required.
The concrete contractor’s job is to turn the plans into a finished foundation, with the layout, forms, reinforcement and concrete placed as specified.
Why Foundations Aren’t One-Size-Fits-All
A foundation has to carry the weight of the building and everything in it, then spread that weight into the ground. A small garage, a two-story house and a commercial building put very different demands on the soil.
Site conditions matter too. Soil type, groundwater, slopes and drainage can all change what kind of foundation makes sense. That’s why the design is tied to the specific building and lot, not copied from one project to the next.
When an Engineer May Be Needed
Not every small project requires a custom engineered foundation, but many do. An engineer may be brought in for larger buildings, unusual soil or water conditions, steep sites, heavy loads or designs that go beyond standard plans. The local building department can explain what is required for your project.
If you’re unsure, asking early is wiser than finding out after plans are drawn. Changes are much easier on paper than after concrete is placed.
What Property Owners Can Do
You don’t need to design the foundation yourself, but you can help the process. Share what you plan to build, how it will be used and anything you know about the site, like wet areas or past fill. In the Burlington area, it’s also helpful to point out spots where water collects after heavy rain.
Ask your design team and contractor how they will coordinate. Clear communication between the people who design and the people who build helps keep the project on track.
