"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

No, beams are the primary load-bearers for flooring or roofing systems, and they distribute the weight of the structure to your foundational supports, while joists bear far less weight and distribute their loads to the beams. Beams are usually thicker and longer, and they have support posts or foundation walls beneath them for support.

The essential difference between an architect and an engineer is that architects typically focus more on the aesthetic design of buildings, although not without consideration for the structural integrity of the building. Engineers focus more on the structural, technical, and practical aspects of whether and how an architectural design can be built as drawn. You may need to hire both types of professionals if you’re designing and building a new home.

Structural engineers typically conduct inspections during a home sale or renovation, looking for signs of structural damage in various structures throughout the building, such as load-bearing walls, joists, beams, roofing trusses, foundations, and chimneys. Some of the warning signs that structural engineers check for include:

  • Dry rot

  • Infestation

  • Shifting or cracking foundations

  • Erosion

  • Water damage

  • Sagging, shifting, or damaged walls, ceilings, or roofing support

Yes, they offer plans for repairs or reinforcements to address issues.

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.
