"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!"

Customers say: Quality work

"Great experience, quick results. Great feedback from building inspector-Many times we do not fully recognize the value a design professional provides to our projects. In this case, I see the value far exceeding the cost in that it provides a clear scope to the depth of the project, allows for accurate materials and time analysis, and limits the probability of inspection failure due to unforeseen factors. It is a comprehensive plan that allows for ease of review and approval."

"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

Yes. Foundation walls are always load-bearing.

It's safe to assume that all exterior walls are load-bearing, or at least have load-bearing characteristics. Some older homes feature porches or bump-outs that don't rest on the home's foundation. However, they still must carry the weight of the roof section they support. Walls containing floor-to-ceiling glass or other non-structural elements must use post and beam configurations to meet load-bearing criteria.

According to the Earthquake Country Alliance—a public and private alliance in California that works to improve earthquake and tsunami readiness—reports that unreinforced masonry, such as stone, bricks, and hollow clay tiles, is more susceptible to earthquake damage. The mortar between bricks isn’t as stable as other building materials and methods.

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.

A construction manager is particularly useful in the case of a large-scale build with custom design elements, so it’s usually worth it to hire one. They can help manage your budget, maintain quality control, oversee timelines, and navigate unexpected hurdles. While construction managers are pricey, they can actually save money in the long run by identifying cost-saving opportunities and ensuring the project stays within budget.
