"They started off great, fast and professional. We had them create blue print plans from my design. I had to pay their full bill before they released final plans which was fine of course. However, my contractor and I ran into a problem on part of their design and engineering and that's when the service went to crap. The contractor and I have been trying to resolve the issue for more than two weeks little success, in fact just the runaround. The Engineer tells us he needs to talk to the architect; the architect says he'll talk to the engineer and nothing happens. That's gone on for two whole weeks. My project is a dead standstill for two weeks which is not acceptable. That's also screwed up the schedules of the contractor and their sub-contractors Therefore what would a bit of five star rating for these guys turned into a 1 to 2. I was very happy with the beginning of the process but once you pay them you can forget about any additional service if you have questions. On the plus side, they seem like nice people to work with, the plans were put together well, and their prices seemed reasonable. As noted above, their follow up service is completely lacking. I would gladly paid another designer more to get complete service that didn't leave me hanging for weeks on end. Today starts week 3 with no resolution."

"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

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, 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.

You should pick steel for your new support beam for a few reasons. While steel is more expensive than other materials, such as laminated veneer lumber or glulam, it offers the following benefits:

  • Fire-resistant

  • Unaffected by pests

  • Longer-lasting

  • Stronger against water damage (when galvanized against rust)

By careful planning and reinforcement to maintain structural integrity.

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.
