"I called five different companies from the Angi list before finding Colonna Consulting. When I called and I explained my situation to Nick (the owner), I immediately knew he was the one. Despite his tight schedule, he managed to fit me in on the same day. We hired Colonna and Nick to inspect our residential structural foundation. Nick responded promptly to my requests and explained everything clearly during the inspection. He completed the report within the same day. Working with him was a pleasure, and his professionalism made the process smooth and stress-free. Thank you very much Nick, for your fast response."

"I was long over due on doing a addition/ remodeling project on my house. I had Victor come out and I went over what my plans were and what I had envisioned. He was quick to offer solutions that met the cities guidelines, which meant part of my addition would be 2 stories, to allow room for my master suite. They prepared the plans worked out all the details with me. The scope of our project was; adding a master suite, enlarging the family room, kitchen remodel, powder room remodel, and some other misc. work. I was pleased with every aspect of there work, from customer service to the quality of the work preformed. One thing I was really impressed by is the attention to details. Victor would spend so much time talking to me about little design elements, how to position the lights, where to put switches, all things which I thought were pointless at the time. But now I realize all those little things really do add up to make a great finished product. All around it was a pleasure working with Build Now NYC"

Structural Engineering questions, answered by experts

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.

The National Association of Home Builders requires repair of any foundation crack of more than one quarter of an inch, although local regulations may vary. In general, any visible crack that is growing in size, allowing water through, or that you have just noticed, is a good reason to call a structural engineer. Cracks can be a sign of a sinking foundation, so an inspection is a good idea for your peace of mind.

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. 

Costs depend on unit complexity, labor, wall mounting needs, and additional accessories like floating shelves.

Yes, an LVL beam is more affordable than the cost of a steel I-beam, totaling between $50 and $200 per linear foot as opposed to the $100 to $400 per linear foot you’d pay for a steel I-beam. Not only is the wood material more affordable than steel, but it’s also more similar to traditional wooden beams and doesn’t require as much retrofitting to connect joists.
