"In renovating our beach cottage in Warwick, RI we found the roof needed structural work. Building inspector required a structural engineered plan. Adam was easy to communicate with. He was timely with his plan and follow up inspection. He was also available by text and phone for questions during the project. He was great to work with!"

"They were excellent. They quickly made a draft that only needed 3 minor adjustments. The final product was exactly what I needed. They referred me to a structural engineer for review. The whole process took half of the time that they initially estimated. I would definitely use them again."

Structural Engineering questions, answered by experts

Absolutely, as it ensures designs are viable and won’t compromise 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.

It is not recommended to cut or drill into LVL (laminated veneer lumber) beams. As major structural components of a home, their composite structure can be compromised by alterations, which can weaken them and lead to cracking over time. If you must make modifications to an LVL beam, it is crucial to consult a structural engineer or general contractor first. A professional can advise on whether it's safe and provide specifics on the appropriate bit size, depth, and directionality for any necessary drilling.

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.

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.
