"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."
