After speaking with several engineers, Engin stood out as the most thorough, knowledgeable, and solution-oriented. He quickly understood the situation, provided a clear path forward, and worked effectively with the City of Oakland Planning and Building Departments to address the issues. Throughout the process, he was professional, communicative, and helped reduce a tremendous amount of stress and uncertainty. His expertise and guidance were invaluable, and I would highly recommend him to anyone needing structural engineering services. Thanks to Engin, a situation that felt overwhelming became manageable.

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. Kardon + Co., Structural Engineers, in a heartbeat to anyone considering seismic strengthening or any other projects requiring the services of an experienced, thorough, detail-oriented, and friendly structural engineer.

We have been working on a 2nd floor addition to a 100 yr old house. As one can imagine, there are…read moremany significant structural issues that may arise unexpectedly when opening up walls and seeing how people build things 100 yrs ago. David and Ray have been incredible since the beginning of the process, helping us navigate through all the structural concerns and always trying to find a value engineering approach - whether it was optimizing depth of foundation work, or finding ways to reinforce old windows, coming up with ways to get headers into locations where there isn't the space, and/or proposing alternative shear wall options when there isn't room to fit things. Ray, our project engineer, has been the best communicating and responding to all our questions and worries. He carefully reviews the problem at hand that arise and often will provide 2 or 3 possible options that our builder can work on. With our current project, Ray is always super prompt to resolve any issues via call or email, or video conference and if necessary an onsite visit to inspect the construction phase. He was just crawling in our crawlspace the other day and notified our builder if some items that needed to be addressed to maintain a positive continuous connection from 2nd floor down to 1st floor and to crawlspace foundation. We are now adding the 2nd floor framing and almost done the most stressful part of the project. We have done 3 major remodels in the past with other firms where it was difficult to get in touch with anybody. With Ray and David at Simplengi Engineering, it has been a very refreshing experience to have experts that promptly responds to all our concerns. Value engineering, great timely communication, attention to detail, common sense, simple and smart engineering. We highly recommend Ray and David and Simplengi Engineering for any structural work. Simply great engineering. We don't plan to do another remodel for 100+ years but if we did, we would hire Simplengi 100% for sure.

To do this, portions of the stuccoed facade of our house and the deck railing had to be removed to make room for new flashing all around. After we came to an agreement with Dan Betyordekom of I Construction to do the work, we braced ourselves for the disruptions and turmoil such a project typically inflicts on an active household (this was not our first such rodeo), dreading the inevitable delays that seem to be part of any construction work. Today, merely 10 days after we signed the contract, we look out on our splendid new deck, which, even according to the building inspector, reflects excellent work. Don's tireless crew showed up on time every day, worked meticulously and professionally, took no shortcuts, cleaned up thoroughly at the end of each day, and went beyond our expectations in every aspect. When they replaced the portions of the stucco and deck railing they had removed, they didn't just paint the replaced portions-they painted the whole house wall and railing... Throughout the work, Dan was in constant contact with us to ensure that our normal routines were not affected by the work, and even made sure that the deck would be finished and usable for a baby shower we had scheduled for our son and his expecting wife.
