"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!"

"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

The 10 10 rule describes the formula most contractors use to determine how much to charge for a job. Allowing for 10% overhead above the total projected cost to do the work and 10% profit sets a contractor up for success, even if there are delays or other problems on the project. This formula isn’t a hard-and-fast rule, but it is a ballpark figure to begin with when estimating your expenses on a job.

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.

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. 

The standard thickness for an LVL beam is between 1.75 inches and 7 inches. However, you can order LVL beams in non-standard sizes as well. When you work with a contractor, they can source beams that are the appropriate size for your project for you after assessing your blueprints.

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.
