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.

My wife and I have been in search for a home to purchase in Oakland CA…read more We had our eye on a beautiful home that was built in 1923. Sadly the disclosures said nothing about the foundation. My agent strongly advised me to hire a structural engineer to assist with the overall inspection. That's when I came across Kais with Oaktown engineers. Kais was very easy to get ahold of, a great value based on other engineers in the area, prompt with response, & available on short notice, a huge plus given the short window to place home offers. During the walk around process my agent and I could quickly tell Kais was not only familiar with houses in Oakland, but was knowledgeable about how the beams, foundation and structure should be settling on a home after one hundred years. I was very pleased with the information provided by Kais in aiding my wife and I's decision on the home. Sadly the home itself needed a whole new foundation, new retaining wall on both the side and front of the home and much more. I felt very reassured in my decision based on the report Kai's provided. If you're looking for a structural engineer, I would absolutely recommend them. They're also a small family business, something we need more of in Oakland. Great job all around Oaktown engineers!

SF Bay sent over one of their engineers whom I found to be extremely knowledgeable and presented us with options on how best to deal with the situation. We were so impressed that we hired them when it was time to do a large addition and remodel to the house. Marcus, the business owner, is an experienced engineer who really knows his trade. During the design process he worked hard to accommodate my "wish lists" that I kept adding to (yikes!). At the same time, he advised me on things I should consider in order to keep costs down. I always felt he had my interests at heart, while at the same time he was doing what was necessary to meet codes, so we could avoid problems during construction and inspections. While engineers and architects seem to be really busy these days, SF Bay's turnaround time is reasonable, and when you need something in a hurry, they try their best to accommodate. This is a top notch engineering company that charges modest and fair pricing for doing excellent work. If you are lucky enough to come across them, don't hesitate, just hire them and you will be glad you did.

They provided a quote ($600) in no time, offered to send out a sample report and asked for the address of the house. When I probed them with what the evaluation involved (such as mapping floor levelness) and whether they were independent without financial ties to contractors, I learned they don't map floor levelness. They didn't answer the bulk of my questions, and they ended stating they don't have the bandwidth to take on my project.

The door casing also went out of square with seasonal changes which prevented the door from closing all the way. It was one of those situations that made me wonder whether the crack was cosmetic or symptomatic of a potential structural issue. I was really impressed with A&J Engineering's professionalism and responsiveness to my inquiry. They replied to my inquiry quickly, requested additional information before quoting a price, reviewed the information I provided before scheduling a site visit, and got a site visit on the calendar fast. Manny and the team that he assembled for the site visit were knowledgable, friendly, and respectful. They explained what they observed during the visit and produced a clear and concise report with photos shortly afterwards. I highly recommend A&J Engineering if you want a professional evaluation of potential structural issues and clear documentation of findings based on a physical site assessment. If your goal is an end-to-end path from assessment to coordination of a structural repair plan (if merited), I'd suggest communicating that expectation at the outset to ensure the scope and deliverables align with what you're ultimately trying to accomplish.
