AY Engineering & Construction

Update: I emailed Adel the comments that were made about our retrofit job (completed 2 years prior) and he sent his foreman by today to take a look and take care of any issues or concerns we had. The foreman installed 40+ Simpson Hurricane ties and added some additional nailing at no cost. We definitely appreciate the response and extra effort by Adel and his foreman, who was very nice and cleaned up any mess that was created.

Go with someone else! Dishonest, overpriced, and does not adequately supervise work. He hires cheap labor that will not hesitate to cut corners.

I recently purchased an old house with a lot of deferred maintenance, including known foundation issues. Adel was the structural engineer who performed the foundation inspection during my escrow period and was able to lay-​out for me exactly what I was getting myself into. Once I closed on the house I got work estimates from several other companies but the bid from AY was the most comprehensive in terms of scope of work (it included full foundation replacement and drainage work) and the most competitively priced.
At the outset of the project I was told to expect a duration of 4 – 6 weeks to completely remove and replace the old foundation and perform the drainage work. Adel’s crew worked their tails off and finished 4 weeks to the day that they began. Despite the fact that additional issues were found in the midst of the work (requiring a change in the plans/​additional work to complete the project appropriately), I was not charged for this, which I appreciated, and this did not delay completion of the project.
Foundation replacement is stressful no matter what, and Adel and his crew did an excellent job of making it as painless a process as possible for us. The crew were courteous, diligent and did excellent work. At all points in our interaction, from initial inspection through completion, Adel has been an absolute pleasure to work with. He is communicative, he is always willing to explain what’s going on and he responds to his client’s needs.

Adel and his crew worked efficiently and consistently to finish a large drainage project around my house. When they hit bedrock, they adjusted the strategy but not my quote, which is very professional. Adel had good communication and clarity regarding any roadblocks and limitations, and although the job took longer than originally anticipated we were very happy.
They also performed some foundation retrofit, anchor bolts, and crawl space drainage as quoted without issue. Along the way they did a few extras on our deck and kept the price fair.
Their crew was respectful and did their best to fulfill minor requests.
We will be calling him again for structural engineering work.

We recently purchased a 1905 Craftsman in N. Oakland and determined that the foundations of both the house and the garage needed full renovation/​replacement. Adel Yassim, a qualified engineer and his crew, are clearly highly experienced in this activity. The process included jacking up each structure clear of the old foundation, cracking out the old, perished concrete, digging out the floor, setting a new frame of solid re-​bar, building the form for and pouring concrete for the new floor and perimeter foundation, and then setting each building down on the new foundation. An extraordinary process finished to specification. Additionally we had perforated piping installed at the rain drop from the pitched roof, in order to drain rain water away from the house to the rear of the garden as required by EB-​MUD.
The entire team of AY E&C were effective and efficient. The resulting work has gone exactly to plan and we are impressed that the foundation cage installed to protect the «pit» of the stand-​up basement in the below-​house area appears to have stabilised the house itself.
Adel provides planning and constant supervision of his work crew at the highest level. I was pleased to have him working on my home and will not hesitate to call on him if ever structural work is required again.

I am currently doing a major remodel of a 1920 Spanish Style home in Kensington, CA near Berkeley. AY Engineering was originally hired to completely redo the foundation of the house which several inspectors told me was needed. Adel and his crew jacked up the house, chiseled out the old foundation, installed a new steel reinforced foundation and mud sill and did it all on time and on budget. I got multiple quotes and AY’s was slightly lower than other quotes. The house also had major dry rot damage due to water getting under the stucco exterior. I was so happy with the foundation work I hired AY to also do the stucco removal, framing repair, and installing new doors. They have done a great job on all of these tasks as well as constructing new retaining walls around the property, installing french drains, and repairing concrete. The project still has a ways to go, but so far I am very happy with their work. Adel Yassim is a certified professional engineer and created all of the engineering drawings and obtained all of the necessary permits from the city and scheduled all inspections for the project. He also worked well with my other contractors (stucco — Giordano Plastering, tile — Gilbert tile). I wouldn’t hesitate to hire Adel again.
… Just an update, the project has now completed and I am just as happy with the interior remodeling, plumbing, and electrical work performed.
