5 Stars! I highly recommend FJ Engineering. They served as the structural engineer of record (SEOR)…read morefor our major single-family home remodel and addition. 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.

She always said she would have the project done by the end of the day but ended up being maybe the end of the month or the following month. They don't communicate with each other in the office either because one of their people no longer works there and nobody in the office knew what was going on with my situation. It has been 8 months since hiring Pacific Sands and got 2 rejections from their lack of design. Still no communication from them. They are hard to get a hold of.

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.

They also diligently worked with the city, project manager, and other contractors to get the job done. Ellen and Julian also provided a very personal touch with guidance in hiring contractors, materials to use for the project, and design. They explained everything to us in detail and were always available to answer any questions and address our concerns. Overall, JZ Structural provided us with a great experience. Would highly recommend getting in touch with them if you need help with building and large renovation projects.

I looked through yelp and even left numerous msgs for various engineers. All of which were either uninterested or charged ridiculous fees. Arsen was recommended to me by a friend and he was perfect for the job. His expertise and knowledge helped us make the very important decision to not remove a structural wall. I recently just hired him again for another project which was in the works since October of last year. After being totally taken advantage of by another engineer, Arsen came by and offered more advise with patience, a detailed explanation regarding the integrity of our building and leveling of another homeowners floors and offered a great report to have on file. He is honest, sincere and above all has a great personality. I would recommend him over and over again!

We confirmed an appointment from 12:00 PM to 1:00 PM in the Temescal area of Corona. Despite his office being located in Corona, he stated he was unable to find the property, even after I provided clear directions. My elderly parents were present at the property to assist, and I had arranged to meet him during my lunch break from work. Upon arrival, I found no issues accessing the property there were no "large rocks" blocking the entrance as he claimed. Unfortunately, he had already left before the scheduled time without proper communication. Instead, he states that we send photos of the structure. This experience was a significant waste of time and demonstrated a lack of professionalism, reliability, and respect for our schedule. I would not recommend this service based on our experience.
