Structural Engineering questions, answered by experts

All foundations have footers, including monolithic slabs. In some cases, the foundation itself acts as the footer, as in the case of a floating slab and a monolithic slab. With a monolithic slab, the footers—which are just the bottom-most portion of the foundation that distributes loads down to stable soil—are a part of the main slab and are constructed with a single pour.

Yes, an LVL beam is more affordable than the cost of a steel I-beam, totaling between $50 and $200 per linear foot as opposed to the $100 to $400 per linear foot you’d pay for a steel I-beam. Not only is the wood material more affordable than steel, but it’s also more similar to traditional wooden beams and doesn’t require as much retrofitting to connect joists.

The process of hiring a structural engineer starts by finding reliable professionals in your area and comparing quotes from at least three of them. From there, you can narrow down your selection by asking some leading questions:

  • Do you have experience working in my specific area?

  • Do you have professional indemnity insurance?

  • What will your structural report cover?

  • Do you charge a flat fee for a structural report or by the hour?

  • How long have you been in business?

  • Do you have a list of customer references?

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

The easiest way to tell if a wall is load bearing is to check if it’s an exterior wall or if it runs perpendicular to the joists above and below it (or parallel to beams). Exterior walls are almost always load-bearing, and walls that run under beams or parallel to them are also usually load-bearing. There are exceptions to these rules, and walls that don’t fit into these categories can still be load-bearing. If you’re unsure, hire a structural engineer to look at your home to assess whether or not the wall is structural.
