"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!"

"I am a contractor that has used ZS design for years now. Every job that I have done ZS has been available on a very level available. Their knowledge goes beyond just providing drawings. They are willing to work with you step by step as a question come about and any issues during the build occur. It’s nice to be able to make a quick call and they are immediate available. Highly recommend their services to builders/contractors and especially home owners who at times have trouble finding that necessary first step to begin their projects."

"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

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.

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.

On average, 6 inches of concrete can hold around 150 pounds per square foot, but the exact weight that 6 inches of concrete can hold depends on factors such as the type of concrete, the reinforcement method, soil conditions below, and structural design. If you’re concerned about the longevity of your concrete patio, walkway, or driveway, hire a professional to help you choose an appropriate concrete thickness and reinforcement method for your needs.

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.

The primary reason homes have crawl spaces is so the foundation can reach down below the frost line to avoid dangerous soil movement and structural damage when the ground freezes. They’re more popular in colder climates where the ground freezes down to a few feet, and slabs are most popular in warmer areas where there is no frost line. Crawl spaces also provide a space for utility lines to run where they’re at less of a risk of freezing.
