"My initial review was somewhat marginal, but now several years later I will say that the reinforcement has been perfect, and they did eventually provide the engineered drawings that were promised shortly after the project completion. Only hitch was with the length of the steel, which they did correct by welding on tabs to each end. Ultimately it was a good job and completed in one day. Would definitely use them again if I needed to reinforce a structure."

"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."

"They were excellent. They quickly made a draft that only needed 3 minor adjustments. The final product was exactly what I needed. They referred me to a structural engineer for review. The whole process took half of the time that they initially estimated. I would definitely use them again."

Customers say: Quick response

"Very Happy With Ryans' Work :) We are in the process of opening a Bakery and Ryan not only provided the designs but helped us figure out how to set things up properly. He consulted with other pros / team members, like his Mechanical Engineer, to confirm all details needed. He met with our team a few times, very professional always and provided us with the final designs. I must say, I was AMAZED! Just Beautiful Work! Thanks Ryan!!! Highly Recommended!!!"

Structural Engineering FAQs, answered by experts

Their expertise in identifying potential problems early and implementing durable solutions safeguards your home’s integrity.

Costs depend on furniture type, size, complexity, and whether additional modifications are needed.

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.

Whether you’re building a new home or building an extension on your existing property, you will likely need both a structural engineer and an architect. A structural engineer will determine what loads your foundation and framing can safely handle, and an architect will draw plans according to those structural calculations to simplify the building process. You can start by contacting a structural engineer near you, as many work alongside architects and can get all of the prep work done at once.

Accurate measurements, sturdy materials, and seamless integration with other structures.
