"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."

Structural Engineering questions, answered by experts

A construction manager is particularly useful in the case of a large-scale build with custom design elements, so it’s usually worth it to hire one. They can help manage your budget, maintain quality control, oversee timelines, and navigate unexpected hurdles. While construction managers are pricey, they can actually save money in the long run by identifying cost-saving opportunities and ensuring the project stays within budget.

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. 

No, it’s not legal for unlicensed individuals to conduct structural calculations for buildings or building repairs. Not only do licensing requirements prevent DIYers from tackling this project, but mistakes can also be extremely dangerous and put your property and anyone inside or near it at risk of severe injury or even death. You should always hire a licensed and certified local structural engineer to make structural calculations.

A structural engineer evaluates any structural components, like floors, foundations, walls, and roofs, to ensure they can support the structure. They also consider the soil quality in your area, potentially extreme weather conditions, and proximity to bodies of water and groundwater to ensure your building can withstand any stresses placed on it by the surrounding environment. Structural engineers work on both new and existing buildings.

Dormers must be able to bear the load of their own construction and the added window. The style of the dormer, however, will determine where the weight loads onto your home's structure. A gable dormer bears the weight on the side walls whereas a shed dormer bears it on the front walls.
