Structural Engineering questions, answered by experts

Building codes for spiral staircases will vary by your location. Most local codes will specify minimum tread width, riser height, handrail requirements, and headroom. These standards help ensure safety and accessibility for all users. Always check local codes before you begin the installation to ensure compliance and avoid costly modifications or fines.

Because of their composite structure, cutting or drilling LVL beams can compromise their integrity. We strongly advise contacting a general contractor or structural engineer before making any alterations to LVL beams. Professionals can also answer questions about choosing between a pier and beam versus slab foundation when designing your project.

A freestanding brick wall that's only one brick thick can usually stand six to eight feet high. If you need a higher wall, it should be at least two bricks thick for adequate stability, and it might require a footing to support the added weight. Additionally, some areas have regulations and codes dictating how high a brick wall can be, so check with local code enforcers to ensure your proposed wall complies with any regulations.

Structural engineers specialize in all aspects of a building’s structural integrity, including the foundation. Foundation engineering is a critical part of structural engineering, so structural engineers are experts in foundation design. Many foundation repair companies either have a structural engineer on staff or one they work closely with, so be sure you look for that when deciding who to hire for foundation repair.

Trusses and rafters each have advantages and disadvantages, so one isn’t necessarily better than the other. For example, trusses are more affordable and often come in prefabricated kits, so they’re easier to build than rafters. However, rafters are available in a variety of designs, so it’s easier to find one that fits your style preferences. Plus, if you want to build an attic at some point down the line, it’s far easier to do that with rafters rather than trusses.
