Frequently Asked Questions (FAQs)
A structural engineer can specialize in foundation work, but they are not limited to it. While a foundation engineer focuses specifically on the design and analysis of building foundations, a structural engineer handles a broader range of structural systems, including foundations, buildings, bridges, and other structures.
A civil engineer covers a wide range of engineering disciplines, including transportation, environmental, geotechnical, water resources, and construction. A structural engineer, however, specializes in the analysis and design of structures that support or resist loads, such as buildings and bridges, ensuring their safety and stability.
A structural engineer typically charges based on the project’s complexity, the engineer’s experience, and the services required. Fees can be hourly, a fixed lump sum, or a percentage of the project’s construction cost. It’s important to discuss the fee structure upfront with your structural engineer to understand the expected costs.
No, a structural engineer is not the same as an architect. While architects focus on the design, aesthetics, and functionality of a building, a structural engineer ensures the design is structurally sound, safe, and compliant with building codes.
You should contact a structural engineer when you need expert advice on the structural integrity of a building, are planning a renovation that involves altering the structure, need a structural inspection, or are constructing a new building. Structural engineers ensure the safety and durability of the construction.
From a structural engineer, you can expect professional services such as structural inspections, design of new structures, analysis of existing structures, recommendations for structural repairs or modifications, and oversight during construction to ensure compliance with the design.
If you are in Seattle and involved in a construction project or need an assessment of a property’s structural integrity, hiring a structural engineer is advisable. They will provide the expertise needed to ensure the structure is safe, functional, and compliant with local building codes.
A structural engineer analyzes, designs, plans, and researches structural components and systems to achieve design goals and ensure the safety and comfort of users or occupants. Their work includes calculating loads, stress, and the strength of different materials and components to design structurally sound and efficient buildings and structures.
