Their expertise literally saved our build from a very poor framing contractor. The contractor caused massive delays due to non-existent planning, mismanaged materials, and repeatedly misinterpretation of the structural stamped drawings, including framing ceiling joists improperly and installation detail errors. Fortunately, the owner, Francisco Garcia, stepped in with efficient practical solutions for every single error while maintaining code compliance and structural integrity. Francisco was incredibly patient, performing comprehensive hold point inspections, clearly explaining details to help contractor's rework and omissions. He accommodated last minute inspection requests time and time again. Now that framing is officially signed off by the city, we have absolute peace of mind. Francisco and his team are the communicative, professional experts you want in your corner, whether for a remodel or new construction. FJ Engineering will contribute to the success of your project through the value they bring from initial development of structural plan drawings and his diligent oversight through final sign-off.

I felt it was important to share our experience with JZ structural as I ultimately went with them…read moregiven their high Yelp reviews. However, my experience was negative to say the least. Ellen was responsive initially, but this was only until they received payment. After this, trying to get a response was like getting blood from a stone: close to impossible. My architect had asked Julian, the engineer, if he could draw a rough mock up before he put together a full set of plans (to which he agreed). We never got this, despite checking in multiple times, and instead, it was only right upon the 'deadline' we had provided for the project that we received a full final set of plans. This was disappointing. The plans themselves were riddled with errors: it seemed like a lot of copy / paste work rather than careful attention to detail. The wrong county was listed, and certain structural details were copy pasted from the wrong city, which my architect had to point out. We had around 30 local contractors look at the plans, as well as two peer reviews of the plans from other licensed structural engineers, and the feedback was that it had been over-designed (consistent with one of the other yelp reviews). After multiple emails attempting to get Julian (the engineer) on a call, he was incredibly defensive, and rude. It was at this point, I was appalled that he would speak to a client like this, so decided to cut ties with this company and use another structural engineer instead. If you are in absolutely no rush, and have no concerns about over-design: perhaps this company will work for you. But for our residential project, this was one of the worst experiences I have had with a "professional" service, and I want to warn others.

I scheduled a consultation with Eugene from STEN Engineering to discuss two very different…read morestructural issues at my house, and I was extremely impressed. The first was figuring out how to realign a very complicated roofline so that rainwater would channel properly. The house has been built and added onto in stages over roughly 100 years, so every addition and alteration made the roofline more complicated and less cohesive. I had literally spent hours sitting on the roof trying to figure out a workable solution. Eugene looked at the situation, thought it through for about 10 minutes, and sketched out an option that simply would never have occurred to me. It was practical, elegant, and made immediate sense. The consultation was some of the best $400 I've spent. The second issue was understanding how well the house is braced for earthquakes and how the existing foundation works structurally. Again, Eugene combined a strong engineering mind with real-world practical experience and explained everything in a way that I could actually understand. I almost never take the time to write reviews, but I was impressed enough that here I am writing one. Eugene is smart, thoughtful, practical, and very good at explaining complicated structural issues in plain English. I would absolutely call him again.
