"I called five different companies from the Angi list before finding Colonna Consulting. When I called and I explained my situation to Nick (the owner), I immediately knew he was the one. Despite his tight schedule, he managed to fit me in on the same day. We hired Colonna and Nick to inspect our residential structural foundation. Nick responded promptly to my requests and explained everything clearly during the inspection. He completed the report within the same day. Working with him was a pleasure, and his professionalism made the process smooth and stress-free. Thank you very much Nick, for your fast response."

"They assessed project, did preliminary design, got helical pile subcontractor. We paid for soil and test drilling, and for topological survey as requested. The sub contractor hired to do scaffolding never did it, so we had to arrange that. So after 4 months of all the prep and 3 or 4 site visits by the engineer, we were ready to go. They never produced the design. After 2 months of emailing and calling we never got a single response. So we were out a couple grand engineering fee, and lost the entire build season. Had to start all over. (This was for a collapsing Livingroom on piers, so it was kind of urgent.) Trying to decide if it is worth going to small claims court to recover our feet. But the big problem is it just did not get done and the engineer just ghosted us, very unprofessional."

Structural Engineering questions, answered by experts

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation. 

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.

Structural engineers draw structural plans, which include detailed drawings of the structural components of a home only. Complete house plans will require additional work from an architect or draftsperson, whose drawings will take the structural drawings into account. They’ll also include more details about the finishing materials and layout of a home, including everything from roofing and flooring materials to the position of furniture, light fixtures, switches, and plumbing fixtures.

Because of their composite structure, cutting or drilling LVL beams can compromise their integrity. We strongly advise contacting a general contractor or structural engineer before making any alterations to LVL beams. Professionals can also answer questions about choosing between a pier and beam versus slab foundation when designing your project.

Trusses and rafters each have advantages and disadvantages, so one isn’t necessarily better than the other. For example, trusses are more affordable and often come in prefabricated kits, so they’re easier to build than rafters. However, rafters are available in a variety of designs, so it’s easier to find one that fits your style preferences. Plus, if you want to build an attic at some point down the line, it’s far easier to do that with rafters rather than trusses.
