I was lucky to have the experience of working with Lokesh and ProStruct Engineering. Lokesh…read more(project manager) always answered quickly to all communications in a clear and responsive way. Additionally the output from the structural engineers was efficiently shown in a virtual meeting describing exactly what changes are required and they worked with the contractor to find the most cost-efficient design. All questions were answered clearly as well as follow-on questions that came up after the design review. After the plans were released and payment was made Lokesh remained very responsive to requests as they come up. I would definitely use Prostruct again if I have another structural engineering project.

After dealing with a basement flood and running a fan and dehumidifier extensively I noticed…read moreseveral cracks in a support beam. It's possible that they'd been there for a long time, but I uploaded the photos to Claude and it strongly recommended getting a structural engineer to assess the damage. I put out several inquiries and ProStruct responded very quickly. I had a free phone consultation with Irvin Chua of ProStruct and he said that he could have an engineer assess the cracked beam and to look for any other sources of damage. Note, that one will need to pay upfront ($875 is their standard fee), which gave me some pause but moved forward as there didn't look to be many structural engineers with a Yelp presence. Irvin arranged for their engineer, Francis, to make a site visit. Francis was professional and confirmed that the foundation and support beams all were in good shape aside from the crack. He went over his recommended repairs and noted that a handyman could handle it and we didn't need a contractor, which saved us money. The report provided was clear and detailed and the handyman had no problems following the recommendations. Repairs are now complete and we have peace of mind that our housing support is solid again.

The county retained Bowman & Williams (B&W) to do preliminary damage evaluations in the disaster area. We were required to obtain 3 quotes to qualify for state and federal disaster relief. B&W offered the required survey and construction design services and always came in with a competitive price. As work actually got underway an alphabet soup of regulatory agencies, FEMA, CA OES, WRCB, F&W, made various demands that impacted the design and B&W always responded quickly to keep the projects on schedule. With all the regulatory hurdles, permits, construction bids and county construction requirements it took until FY 2024-2025 to complete the last project and Bowman & Williams stuck with us thru the last bit of paving and the last guardrail.

Avalon Structural is a truly professional organization across the board - front office, inspectors,…read moreengineers, and on-site repair staff. If you have a foundation crack, save yourself the time and trouble and call Avalon Structural first. I got multiple estimates for my fairly extensive ~23' horizontal crack. I found there are three types of companies. The first type will do the minimum to chip out the rusted rebar, throw some fresh rebar in there, patch it up with a "band-aid", and charge you handsomely for a quick in-and-out job. The second will glance at your foundation and immediately tell you it has to be replaced, for an even more handsome price, of course. And then there is Avalon Structural. They will perform a comprehensive and highly structurally sound repair, removing all compromised material, charge a fair price, and stand behind their work with a strong warranty. If you visit their website, read the articles, and watch the videos explaining the right and wrong ways to perform foundation repairs, you will be well-equipped to choose the right company for your foundation job. Or, you can save the time and just call them. We couldn't be happier with our repair. The foundation looks great and feathers in perfectly with the undamaged foundation sections. The repair team was amazing and extremely respectful of our property. The city inspector signed off with zero issues, which speaks volumes about the quality of their work. A big thank you to Roger, MJ, and the entire Avalon Structural team!

Shrey was the project manager and Marcus was the lead engineer. They worked closely with our architect to complete the initial structural engineering and were very responsive throughout the entire process. After we submitted the plans to the city, there were several questions and comments from the city, and the team responded quickly and worked with our architect to address them. Whenever additional discussion was needed, Shrey and Marcus were readily available for video calls with us and our architect to review the issues and resolve any outstanding items. Their communication and follow-up were excellent. Their pricing was also very reasonable, and overall we were very pleased with the quality of their work, responsiveness, and professionalism. I would definitely recommend SF Bay Engineering to anyone looking for a reliable and responsive structural engineering team.

I hired SF Bay Engineering for seismic retrofit plans under the Earthquake Brace and Bolt program…read more I was told architectural drawings were required before they could proceed, so I hired and paid an architect to prepare them. After multiple back and forth and with SF Bay Engineering admitting they aren't familiar with the requirements, they terminated the contract. They refunded their engineering fee, but the architectural cost remained my responsibility. I brought the matter to small claims court, and the court ruled that because I retained the plans, reimbursement was not warranted. I recommend future clients clarify in writing how architectural costs will be handled if SF Bay Engineering terminates the contract. Happy to provide additional details upon request

Humza and his team do a great job.

He doesn't appear to be phased by not doing what he says or fulfilling anything pertinent to the relatively small part he may have had for this project. The underlying theme of his inconsistent communications and mixed messaging, is akin to throwing out a bunch of fishing lines hoping to snag something with one or more them. So he arrives for an introductory visit to see the job. Then he repeatedly grouses at end of brief visit and for weeks later because he claims to usually charge for an intro appointment. But that's not what we agreed to from the onset. All he seems interested in, way late and after burning this bridge for weeks and not responding timely or at all on topic, is to recoup money for an intro appointment he agreed was no charge, then send vacuous emails off topic and complain that he's not been paid for them either. He punctuates that carnival like behavior by fixating on soliciting a large retainer ahead of some unknown level of service to follow on an hourly basis. Such an unprofessional, predatory manner of stringing along well intentioned potential property owner and some contractors. Not a good or trustworthy or professional look or experience by any measure. If I was to ever revisit this with him, which is highly unlikely, I'd be sure to charge him a retainer up front.
