"John came out and looked at several issues, determined them to be cosmetic not structural and wrote a certified letter to that effect. We got great peace of mind from his visit."

"Mr. McCann came out to assess the water and carpenter ant damage to a wall and foundation sill plate of our home. He was able to quickly evaluate the problem area and provide the structural engineering report and repair task list we needed to get contractor bids on the reconstruction project. Highly recommended."

"We hired Char to help us design an addition to our home in Burien, WA. Our addition adds a 300 sq. ft master suite to our 1100 sq. ft house. Char built our trust quickly. She listened carefully to our concerns, and used her own creativity to make huge improvements to our original plans. Our project wouldn’t have looked the same without her input. Char incorporated very specific requests from us concerning noise reduction, and went above and beyond to research many solutions for us to choose from. Char communicated her schedule clearly, we always knew exactly what she was working on, her deliverables, and what we would discuss in our next meeting. We never had a meeting that wasn’t useful. Char helped us navigate the Burien permit process, making sure the drawing package was complete enough to pass the first time. She reached out to specific city officials ahead of time to anticipate any issues before permit submittal. Char created very detailed drawings and has exceptional drafting skills. She added more detail than required at every stage of the design to help us make critical decisions earlier in the process. Our hired GC complimented Char’s drawing package when we put it out for bid, saying it was better than many that he’s seen. We also hired Char to meet with contractors and review estimates. She was able to help us navigate what was a reasonable price and weed out any weird or misleading estimates. In summary, Char has been a fantastic resource for us and has helped make our first major home improvement project much less daunting."

"Ward Engineering began working with Jared of Cornerstone Home Designs approximately 3 years ago to perform residential design work using Chief Architect design software. I find Jared to be the most capable Chief Architect designer I have ever worked with. Jared is very efficient and thorough at developing the residential Chief Architect models. In addition to being competent, Jared makes himself available to provide personal 1-on-1 training over the internet, which has been a huge blessing to our company and clients."

"I am having a full master bath and kitchen remodel done with new layouts in both rooms and knocking out a wall. Evolution worked with me to quickly get a drawing done of the new layouts so that the contractor could get started on the project. They made sure to include me in the process so that the design would be done exactly as my wife and I envisioned. They communicated effectively throughout the process and were always courteous and professional. I recommend them to anyone with drafting needs."

Structural Engineering questions, answered by experts

Structural engineers are necessary for projects involving alterations to load-bearing structures, foundation work, and compliance with safety standards. This includes home expansions, retaining walls, and significant repairs that impact a property's integrity.

The early stages of building a house are harder than the later stages; laying the foundation and framing the house are two of the most challenging steps. However, it varies for everyone. Some people have difficulty installing HVAC, plumbing, and electricity, while others find it harder to plan the house and secure the necessary permits. 

The depth of any foundation style depends on your climate and how deep the frost line is, as building code requires that the footers of a foundation—which are built into a monolithic slab—sit at least a foot below the frost line. At the southern tip of Florida, for example, a monolithic slab foundation would only need to sit 12 inches under the soil at the widest parts. On some parts of the Canadian border, the frost line is 100 inches, which would mean a minimum of 112 inches, which is prohibitively deep for a monolithic slab.

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.

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.
