"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"

"Pantec Engineering helped us with the planning, engineering, and management of an exterior facade project our condo needed to remedy multiple leaks we were having.

Structural Engineering questions, answered by experts

Most structural engineers offer free quotes, regardless of the size of the job. For simple inspections when buying or selling a home, engineers typically charge a flat fee that may be based solely on your home’s foundation type and square footage. For larger projects, like new construction and major home renovations, an engineer will either perform an analysis of your project and site and provide you with a formal estimate, or they will do a more in-depth assessment and in-person site inspection before coming up with a per-hour or per-project cost estimate. In most cases, the estimate is free.

Yes, ceiling joists are typically load-bearing. However, their primary function is to support the weight of the ceiling and loads applied to it, like lighting fixtures and ceiling fans. They can also help support the roof, especially if they’re part of truss systems. Remember, the load-bearing capacity of ceiling joists depends on the material, size, and space between them. 

Failure to compact the soil during construction is the most common cause of leaning retaining walls. In addition, poor drainage can lead to excessive water pressure behind a retaining wall, pushing against it until it begins to move forward away from the soil it is holding back.

Most lenders and homeowner’s insurance companies don’t mandate a structural engineer’s inspection, so in most cases, it’s not required. However, it’s a good idea to have one done anyway to ensure you know what you’re buying. You can use the report to carry out repairs after closing or even to negotiate the sale price before closing.

Yes, water damage can affect your walls' structural integrity. If the water or moisture sits on the walls for an extended period, it can weaken the drywall, plaster, wood framing, and other materials supporting the wall. That's why it's critical to dry out the area as soon as you notice it.
