"DO NOT HIRE. If you're looking for a misogynist old man to tell you he did his job when he didn't hire Cowen Associates. The worst customer service I have ever experienced. Fred, the owner refused to give me measurements that he claims were written in his drawing and then called me to tell me it's not his job to give me the measurements. He charged me $200 per hour to then tell me I shouldn't be the general contractor on my own job and that I don't know anything."

"Mark Wheeler came out to estimate the necessary work. Josiah and Chris came out a few days later to do the actual surveying. Years ago, one corner had been surveyed and a rail road spike driven into the town road. Subsequently it was paved over and hidden. This point was re-surveyed, and Josiah went to drive in a new mag-nail. That mag-nail hit the top of the rail road spike. As a practicing engineer, I was delighted with their work. _________________________________________________________ [The address above is WRONG. David E.

Structural Engineering questions, answered by experts

Yes, an LVL beam is more affordable than the cost of a steel I-beam, totaling between $50 and $200 per linear foot as opposed to the $100 to $400 per linear foot you’d pay for a steel I-beam. Not only is the wood material more affordable than steel, but it’s also more similar to traditional wooden beams and doesn’t require as much retrofitting to connect joists.

If you’re building new construction or adding onto your existing home, hiring a structural engineer is not only worth it but it’s probably required by your local building department. Structural engineers will ensure you aren’t making your home unsafe in the building process, which is crucial from a safety perspective but also a legal one. It’s also worth hiring a structural engineer if you’re making changes to structural components, like removing a load-bearing wall.

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.

A structural inspection report will include a detailed description of the structural engineer’s findings, applicable photographs, and recommendations to correct the issue. The contents of the report may depend on the scope of the inspection but might also include a time and cost estimate for recommended work to correct any structural problems found during the inspection. 

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.
