"Fennell Engineering did the structural engineering, design and P.E. stamped drawing package for two new structural column and beam systems to remove/open up existing walls on the first level of a three level condo. They were prompt, professional and detailed oriented. The final stamped drawing set that we received was very good."

"The contractors quickly responded to our inquiry. And the leading engineer is very experienced. She walked through the house with us listened carefully of our concerns. She came up with repair solutions right at the spot and discussed with us all the options for each solution. And later she gave us a price well within our budget. All works were done within three weeks from the first walk through. The lead engineer kept us updated about the working progress almost daily.  She replied to our questions even during the weekends. So overall, it is job well done!"

Structural Engineering questions, answered by experts

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.

The process involves initial consultation, concept development, detailed planning, regulatory approvals, and integration of contractor work for project execution.

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.

Through proper drainage solutions and compacting the foundation soil.

It's safe to assume that all exterior walls are load-bearing, or at least have load-bearing characteristics. Some older homes feature porches or bump-outs that don't rest on the home's foundation. However, they still must carry the weight of the roof section they support. Walls containing floor-to-ceiling glass or other non-structural elements must use post and beam configurations to meet load-bearing criteria.
