Structural Engineering questions, answered by experts

Structural engineers typically charge between $100 and $250 per hour, but many jobs won’t be based on a per-hour fee. Instead, the structural engineer will offer a flat rate for the inspection and structural calculations. The flat rate for a structural engineer costs an average of around $550, but you could see prices ranging from $300 to $800, depending on the complexity of your project and how easy it is to access certain parts of your home for the inspection.

Generally, you can tell if a home is bolted to the foundation by checking the foundation for plates. If you see that your foundational plates connect to wood or bolts protruding from them, this means that you have a bolted foundation. However, it's always wise to bring a home inspector in to confirm if your foundation is secure.

On average, 6 inches of concrete can hold around 150 pounds per square foot, but the exact weight that 6 inches of concrete can hold depends on factors such as the type of concrete, the reinforcement method, soil conditions below, and structural design. If you’re concerned about the longevity of your concrete patio, walkway, or driveway, hire a professional to help you choose an appropriate concrete thickness and reinforcement method for your needs.

Indications include cracks in walls, uneven floors, and sticking doors or windows that suggest foundation movements.

A structural inspection report will include a detailed description of the structural engineer’s findings, applicable photographs, and recommendations to correct the issue. The contents of the report may depend on the scope of the inspection but might also include a time and cost estimate for recommended work to correct any structural problems found during the inspection.
