"I am glad angi had a listing for a structural engineer which is hard to find at a reasonable price. scope of the project involved replacing/ repairing a old load bearing wooden post which was giving away due to the age. Mr Joe performed a site visit to my house and connected me with a general contractor to perform the work per his recommendations. The contractor worked closely with him and followed his instructions. Mr Joe was honest, very reasonably priced and stated upon visit that this was a simple problem and I don't have to worry about it. I would definitely consult for future issues."

"We did a full remodel of our place, full new kitchen, and expanded our place into the backyard for a new master suite. Pac Sands did a really great job with our designs. Great tools that made the communication easy with the plans and changes we needed. And they handled the engineering and permitting too, which was great. Highly recommend."

"I had the pleasure of working with Aws on a recent project and was thoroughly impressed by his professionalism and efficiency. He delivered a clean, straightforward structural design that met all the necessary requirements without unnecessary complexity. Aws was fast, reliable, and highly communicative throughout the process, making coordination smooth and strass-free. On top of that, the pricing was very reasonable. I highly recommend Aws and his firm for any structural engineering needs. They offer a great combination of expertise, responsiveness, and value."
