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.

Would highly recommend getting in touch with them if you need help with building and large renovation projects.

We wanted three walls removed and our 8ft ceilings vaulted to 11ft. He spent about 4 hours on site and covered every square foot of our home to make sure he had all the necessary dimensions, pictures and details in order to make an assessment. He presented three options to me for vaulting, discussed pros and cons of each and left me with a digital packet of all of the notes and pictures he took. The turn around time for drawings was one week and required one re-submission to the city with a minor note correction. Overall we are thrilled with the vaulted ceilings which would not have been possible without FJ engineering.
