"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!"

He was incredibly thorough in evaluating my home's foundation and took the time to walk me through his findings, answer all of my questions, and educate me on important aspects of my home's structure.

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."

"Doug & Zach were very helpful in coming up with a creative and Architecturally pleasing design for my house renovation. Being a builder myself I truly appreciated the expertise & ideas used in the design.

"Doug came right out to the house and was very impressed with his ability to freehand the perfect layout to transform the low ceiling attic into 2 new beds and a full bath. The final drafts came a week later and are very thorough and on point. Great experience!"

"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 FAQs, answered by experts

You need to hire a structural engineer when building or modifying any component with a structural load in your home. Common situations where you would need a structural engineer include home inspections when buying or selling a home, investigating possible issues with your foundation, beams, load-bearing walls, or chimneys, breaking ground on a new home or structure on your property, and renovating an old part of your home that could threaten any structural integrity. Home additions and bump-outs also require an engineer.

A structural engineer's report provides a professional assessment of a property's structural condition. It typically includes an evaluation of the foundation, key structural elements like roof trusses, floor joists, studs, beams, and rafters. The report will also contain a detailed description of the engineer's findings, often supported by photographs, and provide recommendations to correct any identified issues. Depending on the scope of the inspection, it might also include an assessment of property drainage, potential issues from environmental conditions like extreme weather or tree placement, and an estimated time and cost for any recommended repairs.

No, a structural engineer is not the same as a builder. A structural engineer is an expert in all things related to the structural integrity of a building. The structural engineer is responsible for calculating the correct materials in terms of load-bearing capacity and overall structural safety. Structural engineers do not perform the actual building of the house or other structures. Rather, the builder executes the plans and designs specified by the structural engineer.

Signs of structural damage include foundation cracks, roof leaks, bouncy floors, crumbling concrete, and cracked or leaning chimneys. Structural damage can make itself apparent in various ways, and sometimes, there may not be obvious signs. Inspect your foundation and roof annually to stay ahead of potentially serious structural problems. 

First, most contractors will have a structural engineer create a report and plan for your project to ensure it’s safe to cut into the load-bearing wall. The contractor will then excavate around the wall, if necessary, measure the opening—allowing for additional space to fit and level the door, and then cut the doorway out. They will likely install a steel lintel as a header over the door for support. Once the doorway is cut out, they’ll demolish the concrete using sledge hammers and masonry chisels, clean up the surrounding concrete, and seal around the door with masonry mortar.
