"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!

"The architect was prompt in responding to my questions and came to see the property after hours, at my convenience. They were full of creative ways to tackle the project. The only reason I did not hire the firm was that a buyer appeared who did not need the structural modification. I highly recommend this firm and will use them in the future."

"Cigano identified a number of important changes to my architectural drawings to strengthen my structure (a car port). The changes recommended and implemented to my plans ensured my Town would issue a building permit. The Town had rejected my initial drawings and required its review and approval by a structural engineer or architect. Cigano really came through and its owner was easy to work with and highly professional. I would highly recommend Cigano."

Structural Engineering questions, 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.

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.

In framing, studs are placed at 16-inch intervals to coincide with the typical spacing of wall materials such as drywall or plywood. This spacing is called "on-center" and is necessary for maintaining structural stability and efficient use of materials. The 16-inch spacing also helps to distribute the weight evenly across the building's structure. For those looking to cut material costs and improve energy efficiency, 24-inch stud spacing can be employed through a method called "advanced framing". This requires careful planning and adherence to local building codes to ensure structural integrity.

If your home's foundation was damaged due to shifting soil, the same problem will reoccur unless you stabilize the structure by adding posts in the bedrock.

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.
