"Mark Brand asked all of the right questions and worked tirelessly with the city permit department to make sure everything we wanted to do would be approved. Beyond being amazing on the phone with the city, his design fit with our mid-century home and anyone who has seen it is amazed at the transformation of our small back yard. We started this project with Mark in 2019, long before COVID-19, and completed the major construction in October of 2020. The actual construction began in May 2020 with demo, to completion in October 2020. Mark and his staff were with us through the entire process, communicating with our Contractor and Pool installer and keeping everyone in the loop and on track. I had never worked with an architect before, and feel grateful that my first experience was with Mark Brand and his team. Fees are explained up front, and although the fees were a healthy part of our budget, I know I got what I paid for! Communication with email and phone calls, as well as site visits were always timely, with any issues explained and problems worked through and resolved to avoid delays."

Customers say: True professional

"I would highly recommend Christopher for his drafting skills.,his 3d software is especially useful for relaying the building concepts. In todays world it is rare to get a person on the phone when needed but Christopher was always there for me to answer questions and was quick to return requests. Be sure to give him all the necessary design criteria in the beginning to smooth out the design process for him which will ultimately save you money."

"They were excellent. They quickly made a draft that only needed 3 minor adjustments. The final product was exactly what I needed. They referred me to a structural engineer for review. The whole process took half of the time that they initially estimated. I would definitely use them again."

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 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.

Yes, a one-story house can have a load-bearing wall. The load-bearing walls in a single-story home are usually the exterior walls. If the house has a basement with exposed walls, the arrangement of the beams can help indicate what walls are load-bearing.

On average, 6 inches of concrete can hold around 150 pounds per square foot, but the exact weight that 6 inches of concrete can hold depends on factors such as the type of concrete, the reinforcement method, soil conditions below, and structural design. If you’re concerned about the longevity of your concrete patio, walkway, or driveway, hire a professional to help you choose an appropriate concrete thickness and reinforcement method for your needs.

The average cost to hire a structural engineer is about $550, with prices generally ranging from $200 to $1,500. Structural engineers may charge a flat rate, by the project, by square footage, or an hourly rate, which is typically between $100 and $250. Many jobs, such as inspections and structural calculations, are billed at a flat rate, which often falls between $300 and $800. The final cost depends on several factors, including the project's type, scope, size, complexity, ease of access for inspection, and your geographic location.
