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.

From the very beginning, we were impressed with Senthil, Ryan and other members of Zenith team's level of professionalism, prompt response, architectural knowledge and effective communication.This level of service was seamless through our entire engagement with Zenith Engineers Inc., from obtaining the building permit to successfully passing all necessary inspections by the SF Building Department. No one questions their architectural work because they are so good at what they do. We had some initial concerns after reading negative reviews, but as the project progressed, it became clear that those comments were based on personal grievances, rather than valid concerns. The team at Zenith Engineers Inc. has a high level of professional ethics and integrity. Zenith's management team had explained to us early on in the project, the strict adherence to code and compliance was paramount throughout the project. If Zenith compromises to satisfy unsatisfied clients, the building will end up being non-compliant and more importantly unsafe. We truly appreciate Zenith's commitment to quality and integrity, even if it means earning a few negative reviews along the way, which seem rather unfair to them as they are simply doing their job. I am extremely satisfied with the professional and excellent work the team at Zenith Engineers Inc. provided us and will hire them in a heartbeat for all our future structural and/or seismic engineering needs. Thank you Senthil, Ryan and the Zenith engineering team for your professionalism and support. It was our best decision to work with you and experience such high standard of professionalism, work ethic, and integrity.

After having used Zenith for multiple projects in the last few years, looks like it's finally time…read moreto look for someone else for the next one. We started using Zenith because of its responsiveness and effectiveness when it came to structural design. With them as part of our team, we were able to keep up with the City submittal and response timelines we had set. Fast forward to today, and we can't get a hold of anyone. When we do, it's always an excuse for why they didn't respond, without a resolution. We sent them the last City comments 30 days ago and have yet to get anything viable to re-submit back to the city. Given that this is a 30-unit hotel project, going with a different firm now will mean a complete re-design of the project; an absolutely painful exercise that will set us back months. Zenith knows that. So it's absolutely shameful for them to act in a way that would even suggest that our only choice is to get the entire project re-designed by another firm just to have it keep moving forward. So much for "we respond to emails within 30 minutes and always answer phone calls" as outlined on one of their online profile. Knowing how we were treated on this round of City comments and the fact that the entire company seems complacent about what they try to embody in their rhetoric, I would stay away for any future project.

Scheduling with Clair was incredibly fast--it only took about 2 minutes to set up a general inspection. Julia, my inspector, was fantastic. She was professional, knowledgeable, and very patient with all my questions. After a thorough walkthrough of both the inside and outside of my home, she explained that the foundation itself is fine--the cracks were just poorly mixed surface cement that needs repatching. She even caught two other issues during the walkthrough that I wouldn't have noticed otherwise. I really appreciate the honesty and the extra effort. Great experience!

She jumped out her car and pointed out my gutters and told me I need to clean them. that is my problem, very unprofessional as she danced around my house with a camera snapping photos. And my barge rafters need to be painted. My windows aren't installed right upon entering my basement to show her the wall of concern and my coming out of the wall of the corner of the damage wall she did not address my concerns of my Watermain and pointed out. I had a lot of water stain around my home. They me $695 for a report of everything that I already knew very disappointed in this company. Afterwards, the next day, the owner calls me and it says that his inspector is certified engineer for 10 years with the company and that I got what I asked for and I did not want a visual report at all. I already knew what was wrong with my Home. I told him I was looking for a solution to my problem and my safety concerns addressed. But instead, I was giving a visual report telling me everything. I told him when I talk to them on the phone. Why would I pay you $695 and tell me something I already knew don't make no sense. And then the owner asked me what exactly I wanted from them and I told him I needed of my main concern my wall. He said he would add the report. For me the next day I got the report and all I got was sample picture of random wall that had nothing to do with my consumer beware they are good a scam to get my money that's about it. And they were paid cash and I never did receive a receipt for that. Disappointment.

Part one of a two part foundation project Recently we had…read moreour house foundation repaired by Groundworks out of Fairfield. One bedroom had sunk by almost 5 inches as that part of the house had been built on fill. In order to restore the house to it's proper level numerous foundation jacks and floor leveling screw jacks were required. In addition some landscaping bushes and pvc sprinkler pipes had to temporarily removed. Groundworks had informed me prior to starting work what would be required to successfully complete this project and had my full approval. The house is now level, the doors no longer swing on their own and the interior cracks between the walls and ceiling joints no longer exist. Prior to the crew leaving the yard was cleaned up and the pvc pipes replaced. Best of all Groundworks will come back annually to the next 5 years and make any necessary adjustments. The Groundworks crew that made this happen was Andrew, the site supervisor, Charlie and Allen. Their performance and daily communication was superior on all levels. This is part 2. The Groundworks Poly crew of Anthony & Brian were very fast and efficient in completing their part of the foundation repair contract which was to level our family room slab floor. Fast, yes, but Anthony did take the time to not only explain what they were going to do but also walked me through the process as they were working.
