"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."

"He's fantastic--both a structural engineer and contractor! As many contractors as I have found, there are not many that are so intelligent as to pick up on everything you are saying, problem solve as you are talking, and communicate solutions immediately. He is also a teacher and was the only contractor that gave me a visual description of what has been going on under my house in my 20 years of living here."

"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!

Structural Engineering questions, answered by experts

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.

Stone, marble, and brick are common building materials of Neoclassical architecture, though you will also find wood flooring and a range of natural stone tiles. Since several home styles fall under Neoclassical architects' umbrella, a range of building materials—including traditional wood framing—will make an appearance.

You need to hire a structural engineer when building or modifying any component with a structural load in your home. Common situations where you would need a structural engineer include home inspections when buying or selling a home, investigating possible issues with your foundation, beams, load-bearing walls, or chimneys, breaking ground on a new home or structure on your property, and renovating an old part of your home that could threaten any structural integrity. Home additions and bump-outs also require an engineer.

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.

The average cost to hire a structural engineer is about $550, with prices generally ranging from $200 to $1,500. Structural engineers may charge a flat rate, by the project, by square footage, or an hourly rate, which is typically between $100 and $250. Many jobs, such as inspections and structural calculations, are billed at a flat rate, which often falls between $300 and $800. The final cost depends on several factors, including the project's type, scope, size, complexity, ease of access for inspection, and your geographic location.
