"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."

"I searched the local area on Angies list for an architect. I found Three D Concepts and gave a call to Joe. He came to the house and spent about an hour looking at what would need to be done to take this wall out. Joe thoroughly explained what the job required as far as structural support in the basement and necessary dimensions of the beam to be installed in place of the wall. I decided to move forward with Joe, within approximately 2 weeks he had the drawings finished. He provided me with multiple copies which 1 would be submitted to the town and others to contractors for estimates.
I asked Joe to draw plans for the front entrance way as well. This drawing because it was the front doorway of the house required a few rough versions to be drawn to get an idea of how it would look. We discussed the drawings a few times and once we agreed which one looked best, he finished it and brought the final drafts to my house with the wall removal drawings. Both sets of drawing were professionally done on large 24'' x 36'' size paper with great detail and all of Joe's business and license information present.
I would recommend Joe to a friend and use him again for future work. Thank you!

"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."

"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

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.

Signs of structural damage include foundation cracks, roof leaks, bouncy floors, crumbling concrete, and cracked or leaning chimneys. Structural damage can make itself apparent in various ways, and sometimes, there may not be obvious signs. Inspect your foundation and roof annually to stay ahead of potentially serious structural problems. 

First, most contractors will have a structural engineer create a report and plan for your project to ensure it’s safe to cut into the load-bearing wall. The contractor will then excavate around the wall, if necessary, measure the opening—allowing for additional space to fit and level the door, and then cut the doorway out. They will likely install a steel lintel as a header over the door for support. Once the doorway is cut out, they’ll demolish the concrete using sledge hammers and masonry chisels, clean up the surrounding concrete, and seal around the door with masonry mortar. 

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation. 

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.
