"We recently completed a project with Lallygone to remove 3 columns from my basement. The entire experience from scheduling a consultation with the engineer to completion of the job was seamless. The team is knowledgeable, courteous and very professional. I strongly recommend them for replacing lally columns or any structural improvements in existing or new homes. George thanks for your honest recommendations, Chris for your in-depth inspection and detailed explanation & Lena for managing it end to end.. thanks for the wonderful experience."

"Joe and team at Three D Concepts did a phenomenal job. Very professional and very knowledgeable in his field. Joe provided insight and ideas that I didn't even think of when starting the project. He was also very familiar with my township and the surrounding areas, which is important whenever doing a home extension. Knowing how to navigate the various zoning laws is so important with something like this. I searched around quite a bit for a qualified architect who is trust worthy. Many wanted to charge a percentage of the construction job. In my opinion, the cost of tile that I choose, shouldn't dictate my architectural costs. Joe provided a flat fee quote upfront. This was a breathe of fresh air and took a lot of uncertainty out of the process. Finally, the quality of work was top notch. We absolutely love the plans that he put together for us. Our dream home will now finally become a reality thanks to Joe and Three D Concepts."

"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."

"Julian delivered exceptional engineering analysis and design work for my residential gut rehab. He was consistently available, willing to help, and brought strong technical expertise to every discussion. His vision for an open‑wall layout led to the installation of a structural beam that completely transformed the home’s flow and created a true open‑concept space we never thought possible. He worked efficiently, communicated clearly, and carried himself with total professionalism. I highly recommend him to anyone looking to upgrade or reimagine their living space."

Structural Engineering questions, answered by experts

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)

Most lenders and homeowner’s insurance companies don’t mandate a structural engineer’s inspection, so in most cases, it’s not required. However, it’s a good idea to have one done anyway to ensure you know what you’re buying. You can use the report to carry out repairs after closing or even to negotiate the sale price before closing.

Yes, all states require structural engineers to carry the proper license, with specifics determined by each state. You can use Angi’s state licensing tool to confirm that the structural engineer you’re considering holds the required licensing to tackle your job. Hiring an unlicensed structural engineer will not only cause issues with permits but it could also lead to an unsafe building. The cost of a professional, licensed, and experienced engineer is well worth the investment.

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.

A 4-inch-thick concrete slab can support around 4,000 pounds per square foot if a contractor reinforces the slab with rebar, while that same slab without reinforcements will support closer to 1,000 pounds. For the purposes of a patio, 4 inches in thickness without reinforcement should suffice unless you’re installing heavy kitchen equipment or a hot tub on it. In those cases, reinforcing your slab and sticking with 4 inches of thickness should provide plenty of strength.
