Structural Engineering questions, answered by experts

Whether you’re building a new home or building an extension on your existing property, you will likely need both a structural engineer and an architect. A structural engineer will determine what loads your foundation and framing can safely handle, and an architect will draw plans according to those structural calculations to simplify the building process. You can start by contacting a structural engineer near you, as many work alongside architects and can get all of the prep work done at once.

Failure to compact the soil during construction is the most common cause of leaning retaining walls. In addition, poor drainage can lead to excessive water pressure behind a retaining wall, pushing against it until it begins to move forward away from the soil it is holding back.

While concrete walls do not need to "breathe" in the traditional sense of the word, they do require waterproofing and dehumidifying methods, particularly in basements below the water table. Concrete both contains moisture from its initial installation and can absorb water when exposed. Ensuring proper basement ventilation , installing a vapor barrier, and controlling water exposure are all important tasks.

Through detailed analysis of load paths, materials, and existing damages.

Hiring a structural engineer costs about $550 on average. However, prices range from as low as $200 up to $1,500. Structural engineers may charge by project, hourly, or by the square footage, making it important to understand how your chosen engineer structures their estimates. Additional cost factors include project type, the scope of work, the size of the project, and your geographic location.
