"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."

"I?m Edison Matteo from Sunshine Estimation, based in Erie, PA. We worked with NextEdge Builders Corp for our architectural project, and I personally managed the entire process from start to finish. Initially, I had them prepare detailed CAD drawings for our project, and the quality and accuracy of these drawings impressed me immediately. Once the drawings were completed, I requested a cost estimate based directly on them. The estimate provided was extremely precise, with an accuracy of around 98?99%, which gave me great confidence in planning our budget and moving forward. What sets NextEdge Builders Corp apart is that everything is handled under one roof. From drafting to estimation, the process is seamless, reducing the need for constant revisions or coordinating multiple service providers. Their communication, professionalism, and attention to detail truly stand out. I highly recommend NextEdge Builders Corp for anyone looking for reliable and accurate drafting and estimation se"

Structural Engineering questions, answered by experts

The costs depend on the type of wood, labor, roofing material, permits, and whether additional storage or enclosed walls are included.

While concrete walls do not need to "breathe" in the traditional sense of the word, they do require waterproofing and dehumidifying methods, particularly in basements below the water table. Concrete both contains moisture from its initial installation and can absorb water when exposed. Ensuring proper basement ventilation , installing a vapor barrier, and controlling water exposure are all important tasks.

Whether you’re building a new home or building an extension on your existing property, you will likely need both a structural engineer and an architect. A structural engineer will determine what loads your foundation and framing can safely handle, and an architect will draw plans according to those structural calculations to simplify the building process. You can start by contacting a structural engineer near you, as many work alongside architects and can get all of the prep work done at once.

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.

No, squeaky floors do not always mean there is structural damage. The noise is often caused by friction from issues like loose floorboards, gaps between the subfloor and joists, or loose subflooring. While many squeaks are harmless, persistent or worsening noise could indicate a more severe problem. If you notice other signs of structural damage—such as soft or sagging floors, cracks running from the wall to the ceiling, or horizontal cracks in your foundation—it's best to have a professional inspect your floor to determine the root cause.
