"We loved working with Dwight! We have had the opportunity to work with him on both residential (our home) and commercial projects and couldn't be happier with the results. At home, he helped us to make our dream a reality. His designs were creative and well thought-out and his consultations before and during the construction were VERY helpful. We hope to work with him again soon!"

"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"

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.

The 10 10 rule describes the formula most contractors use to determine how much to charge for a job. Allowing for 10% overhead above the total projected cost to do the work and 10% profit sets a contractor up for success, even if there are delays or other problems on the project. This formula isn’t a hard-and-fast rule, but it is a ballpark figure to begin with when estimating your expenses on a job.

Yes, you can put a doorway in a structural wall; in fact, most exterior doors are set into structural walls. The project is a little more challenging than installing a door in a non-load-bearing wall because you need a structural engineer to assess the wall and make sure it’s safe to create a wall opening. Your engineer’s report will include instructions for your contractor on how and where to install additional supports, like steel headers above the door, to distribute the weight above to the wall on either side of the door.

Yes, you can build over a stump if the roots are no longer alive. Living roots will continue to grow and may damage your new construction over time. Similarly, you should also remove rotting stumps because they may continue to attract pests and even cause new structures (especially those made from wood) to decompose as well.

In framing, studs are placed at 16-inch intervals to coincide with the typical spacing of wall materials such as drywall or plywood. This spacing is called "on-center" and is necessary for maintaining structural stability and efficient use of materials. The 16-inch spacing also helps to distribute the weight evenly across the building's structure. For those looking to cut material costs and improve energy efficiency, 24-inch stud spacing can be employed through a method called "advanced framing". This requires careful planning and adherence to local building codes to ensure structural integrity.
