I contacted the engineering group at MKM and was put in contact with Nick Stuart. Nick came out and did a site visit and then worked with a designer to work on a voluntary repair plan to better support my foundation and wall. The experience while working with him was great. He was very responsive, kept to a schedule and came in at the budgeted amount forecasted for the work. He even did above and beyond items, dropping copy of plans off to me while I was at the permit office! I would absolutely recommend them in the future and plan to work with them again on a second unit in the upcoming months. They are extremely professional, have a great work ethic and do a great job!

I initially signed a contract with Prostruct, but after Irvin reviewed my photos, he demonstrated a level of integrity that is rare to find. Instead of taking the job, he honestly informed me that my specific issues fell outside their scope. He took the time to explain what I was seeing, referred me to a geotechnical engineer who could actually solve the problem, and issued me a full refund. I greatly appreciated his transparency and professional guidance. I highly recommend Prostruct Engineering to anyone looking for an honest assessment--they clearly prioritize the customer's needs over their own bottom line.

Their team is very professional, responsive, and easy to work with. The plans were well-prepared and detailed, and the city approved them with minimal corrections, which really speaks about their quality and attention to detail. One of the projects was on a hillside property, where the foundation requirements were quite intense, but their team handled it seamlessly with well-thought-out and detailed designs. See pics. They always delivered on time and maintained excellent communication throughout the process, keeping me informed at every step. I highly recommend ProStruct Engineering to anyone looking for reliable and efficient structural design services! A special mention to Lokesh, who I worked with directly -- he was very responsive, understood my needs clearly, and made sure everything was addressed on time.

Fast, efficient, quality work that flew with high flying colors through the City Permits Department in one pass. I was impressed by them in all the ways our project worked out and hired them again for a very consequential project. Their thoroughness impressed me and my contractor ("These guys sure are covering all the bases brilliantly", he said of them). We wanted to lift up the ceiling of our kitchen and family room. Because the previous framing work was lacking and because we recently replaced our roof and installed a solar system with increased wind exposure, A1F1 explained we needed to install a big beam with a pier in concrete under the house. They provided all the drawings and calculations documentation needed for the City to approve again at first pass. Work is now under progress, and I have been at awe on how everything is working totally like clockwork. Highly recommended!

Anthony, from A1F1, took time out of his busy schedule to come out and look for almost no cost. He was on time, professional, and extremely knowledgeable. He actually advised me about another wall bordering my kitchen, and told me I could remove that wall since it wasn't load bearing. So now, I will remove 2 walls, and have a totally open floor plan. Can't say enough about the guy. If you are looking for a structural engineer, believe me, u won't get a better value.

The business practice used on my elderly mother during covid was so unscrupulous, we considered filing suit for elder abuse, as they attempted to grossly over charge her for their mistakes and miscommunications, Eric was especially unscrupulous and totally inept at his simple job. They had the nerve to charge us for miscommunications on their end and then had their lawyer threaten us and then back down and go silent when they realized they didn't have a leg to stand on. Don't walk. Run. I laughed when I saw their 101 billboard advertising themselves as first responders. They are first responders like a vulture is a first responder to road kill. In other words, I am saying they engage in predatory business practices. If anybody else has been threatened with legal action for exposing these people please contact me and I can put you in touch with the best anti slapp attorney in northern California that already knows about these people. I am also happy to be a witness in any other legal action against this company. I have documents and emails that back up my claims here.

I contacted Joshua B. Kardon, PhD, SE, F.ASCE, on the advice of a friend who is an architect after…read morewe won the bidding war (for $869K) on a 1924 Craftsman home in San Leandro in 2019. It had several issues, especially a problematic (cracked) original foundation. When Joshua Kardon informed us that we might have to spend a considerable portion of the above purchase price to properly fix up the house, make it earthquake-safe, and bring it up to current codes, we decided to pass on this lovely house. (He told us that replacing the cracked original foundation and raising the basement ceiling from 75 inches height to 96 inches on the 1400-square-foot home - all by itself - might cost $200-$300,000 and take many months. The home had other issues, too.) We later purchased a smaller 1954 ranch-style home in almost-as-built condition and called Joshua Kardon again for a consultation about seismic strengthening. He designed the almost-finished project that spans the front of our home and protects it against earthquakes. Joshua Kardon selected a "SkinnyBrace" by Thor Matteson, SE, of Quake Bracing LLC as the most cost-effective way to anchor our garage and the front of the house using attic collectors and garage shear walls. Nieto Valle Construction of Hayward has executed his designs and will soon finish the garage drywall and attic insulation. Joshua B. Kardon, SE, has always insisted on designing and implementing the best possible seismic strengthening solution for us and his solution is now in place. His attention to detail and insistence on doing things "the right way" are highly reassuring and have produced great results. Josh is also very personable, patient in educating us as to why certain design strategies work better, and has a great sense of humor. I would recommend Joshua B.
