"Evolution design worked with me on designing and addition for a 100 and 5 year old house. We worked on the dimensions of the addition Plus the materials. Evolution understood the local zoning which was amazing that they knew that. We have not started construction. And evolution can help pull the permits and I'm considering them for that as well. All in all it was a long project but it was done efficiently, working with several of the staff an the departments."

"We highly recommend Berper Construction LLC. We listed our project on Angi and literally 5 minutes later we received a call from Gerardo to set up an appointment to look at and give us an estimate. He came over that same day and sent us a bid the very next day. We accepted him and his team to do the work and just over a week later once we got our funds together, they began working on our project and were finished in 2 days! He was very thorough explaining what needed to be done and sent us pictures from Home Depot of different items we needed for the job and let us pick out exactly what we wanted. Always on time, very kind, and honest which is much appreciated. Gerardo made sure that he did the job exactly how we wanted and never did anything without getting our approval first. We love our 9x9 pergola over our hot tub, thank you Gerardo, Edwin, and the rest of your team! We will definitely call again for other projects in the future! :)"

Structural Engineering FAQs, answered by experts

The easiest way to tell if a wall is load bearing is to check if it’s an exterior wall or if it runs perpendicular to the joists above and below it (or parallel to beams). Exterior walls are almost always load-bearing, and walls that run under beams or parallel to them are also usually load-bearing. There are exceptions to these rules, and walls that don’t fit into these categories can still be load-bearing. If you’re unsure, hire a structural engineer to look at your home to assess whether or not the wall is structural.

No, a structural engineer is not the same as a builder. A structural engineer is an expert in all things related to the structural integrity of a building. The structural engineer is responsible for calculating the correct materials in terms of load-bearing capacity and overall structural safety. Structural engineers do not perform the actual building of the house or other structures. Rather, the builder executes the plans and designs specified by the structural engineer.

Yes, ceiling joists are typically load-bearing. However, their primary function is to support the weight of the ceiling and loads applied to it, like lighting fixtures and ceiling fans. They can also help support the roof, especially if they’re part of truss systems. Remember, the load-bearing capacity of ceiling joists depends on the material, size, and space between them. 

All foundations have footers, including monolithic slabs. In some cases, the foundation itself acts as the footer, as in the case of a floating slab and a monolithic slab. With a monolithic slab, the footers—which are just the bottom-most portion of the foundation that distributes loads down to stable soil—are a part of the main slab and are constructed with a single pour.

Most structural engineers offer free quotes, regardless of the size of the job. For simple inspections when buying or selling a home, engineers typically charge a flat fee that may be based solely on your home’s foundation type and square footage. For larger projects, like new construction and major home renovations, an engineer will either perform an analysis of your project and site and provide you with a formal estimate, or they will do a more in-depth assessment and in-person site inspection before coming up with a per-hour or per-project cost estimate. In most cases, the estimate is free.
