"I would (and almost certainly will) work with AGGO again! We are buying a house and something came up where we needed a structural engineer to inspect something on very short notice. I reached out though Angi's to any company that might possibly employ structural engineers and Linda, a Structural Engineer with AGGO got back to me right away, first thing in the morning and was able to squeeze us in that very night. Linda was thoughtful and thorough. She careful looked over everything and even brought a large, bright light since it was after dark. She took her time, answered all of our questions, and gave us advice on other concerns and things to watch out for as well as reassuring us about things we didn't need to worry about in this situation. Even though she was probably working past her normal work hours to squeeze us in, nothing felt rushed or hasty. "

Structural Engineering questions, answered by experts

By careful planning and reinforcement to maintain structural integrity.

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.

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.

First, most contractors will have a structural engineer create a report and plan for your project to ensure it’s safe to cut into the load-bearing wall. The contractor will then excavate around the wall, if necessary, measure the opening—allowing for additional space to fit and level the door, and then cut the doorway out. They will likely install a steel lintel as a header over the door for support. Once the doorway is cut out, they’ll demolish the concrete using sledge hammers and masonry chisels, clean up the surrounding concrete, and seal around the door with masonry mortar. 

Yes. Foundation walls are always load-bearing.
