"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."

"Aaron was timely in response and was quick to schedule an inspection. Willing to travel and very reasonable in price even with the travel expense added in. I would recommend Aaron for verifying the structural soundness of a foundation and will definitely keep his name in my list of preferred business professionals to work with."

"I was really under the gun due to a prior Architectural firm not performing their duties per building plan codes. Not only were the plans incomplete but the City Plan Reviewer states(The Worst plans he’s ever seen) they will not make adjustments unless there is an additional charge for Thousands. Evaluation’s saved my clients and drew our project per code, along with Engineering in less time then they quoted. I highly recommended them, Especially Kirsten. You went above and beyond trying to coordinate this project. The staff was very professional and I will use them on all my projects. Sincerely, Frank B BCM Builders"

"He is a brilliant architect. I live in an old home which is always tricky. He designed our master bedroom in a 90 year old house in a way that didn't need any major structural changes. It looked as though the house was originally made for that design! The design he came up with also included everything down to the last detail. He does quality work and the guys he works with clean up after themselves. In the beginning of each project he extrapolates what it is that you are looking for. He doesn't try to push his latest design on you. His focus is solely on what each customer wants and he is very open minded to the taste of each client. He is incredibly efficient and I have never seen anybody work the way he does. Trent is very good at avoiding mistakes and his communications skills are excellent. He is very knowledgeable in his field, and because of that he completes projects very quickly and delivers high quality results. It is fun working with Trent because he makes it easy!"

Structural Engineering questions, answered by experts

You need to hire a structural engineer when building or modifying any component with a structural load in your home. Common situations where you would need a structural engineer include home inspections when buying or selling a home, investigating possible issues with your foundation, beams, load-bearing walls, or chimneys, breaking ground on a new home or structure on your property, and renovating an old part of your home that could threaten any structural integrity. Home additions and bump-outs also require an engineer.

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.

Yes, walls on the top floor can be load-bearing if stacked on the floor’s foundation.
