"I hired Mr. Csak as a consultant to advise me on structural improvements for my home. He did an excellent job. He had a very organized approach. We walked the exterior of the property first and along the way he pointed out all the key issues. Then we did the same with the interior. Louis didn’t just focus on the site of the proposed improvements but he evaluated the entire property, so that he could give me reasoned, detailed advice about my project. He understood the big picture, but he also got down on his hands and knees to take very precise measurements, when necessary. He was very focused on my safety in the home and made sure to test for radon, even though that was outside the scope of the engagement. Since Louis is a professional, licensed engineer you are getting someone with deep technical expertise who also has years of practical applications. Louis is very honest and forthright. He is a true pleasure to work with and I would use him again. I recommend him most highly."

"I am having a full master bath and kitchen remodel done with new layouts in both rooms and knocking out a wall. Evolution worked with me to quickly get a drawing done of the new layouts so that the contractor could get started on the project. They made sure to include me in the process so that the design would be done exactly as my wife and I envisioned. They communicated effectively throughout the process and were always courteous and professional. I recommend them to anyone with drafting needs."

"Gary was highly recommended to us by friends who had used his services. He worked with us about a possible addition to our home. He spent much time with us, was extremely clear about each stage of his consultation and specs for the proposed project, paid very close attention to both our needs and our concerns. His architectual blueprints were increasingly detailed and promptly delivered, including every possible feature our addition might contain or require, and suggested a number of contractors to consult and get cost figures for the project. We were in constant communication with Gary as to details, costs, and possible complications, and he suggested changes in the project as these complications arose and multiplied. When we decided not to go ahead with the construction, it was not due to anything wanting in our consulations with Gary, but after discussions with our financial managers and accountants, we had to conclude that what we had had in mind was not financially feasible for a number of reasons. Throughout, Gary was very gracious in responding to our concerns, and to our conclusion not to go ahead."

Structural Engineering FAQs, answered by experts

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?

You should avoid drilling or cutting into load-bearing beams because removing material will weaken it and increase the risk of structural damage or even collapse. If you do need to drill into a load-bearing beam, speak with a structural engineer first to discuss where it’s safest to drill and the width and depth of the bit that’s safe to use.

In many areas, advice from a structural engineer or an architect will be required by your building department before you can remove a wall, but even if it’s not necessary, it’s a good idea. Accidentally removing a load-bearing wall—even if a general contractor advises that it’s safe—can cause major structural damage, putting you and your family at risk and potentially costing thousands or tens of thousands of dollars in property damage.

Many horizontal cracks in home foundations result from water and soil pressure from outside of the building or from a footing that is shifting. Under those circumstances, horizontal cracks are a structural problem that requires repair before they become worse and more difficult to fix. However, in very specific cases, thin horizontal cracks may simply be a cosmetic blemish due to concrete shrinkage.

The standard thickness for an LVL beam is between 1.75 inches and 7 inches. However, you can order LVL beams in non-standard sizes as well. When you work with a contractor, they can source beams that are the appropriate size for your project for you after assessing your blueprints.
