I also want to mention that my project took less time than originally thought. As a result I was invoiced for three hundred dollars less to reflect the actual time spent. This is definitely the firm to use if you want great customer service, plans that meet LADBS requirements and charges that reflect the actual time spent on your project.

A few hiccups along the way with the final permit but Sam acknowledged the mistake on his end and said he would sign off the edits in the revision phase of construction. I will give an updated review once that time comes. Quality: quality of work was good. Efficient in communication and dealing with a difficult city in a permitting process. Took about 6 months for the permits and the city kicked back for corrections 2x which is pretty standard. Value: felt his pricing was fair and reasonable Customer service: always responds to phone calls. Even after our final payment when we had questions or needed assistance. So not a "take your money" and we are done type of guy Overall impression: would use him in the future for any architectural or structural engineering jobs

The geologist himself is a nice enough guy and I'm sure he knows his craft. It was because of him…read morethe rating is a 3 star. Otherwise it would be a 1. The company itself, internal staff, are very difficult to work with. As an example: they rarely return phone calls or emails in a timely manner. When they do respond to an email, the tone is less than friendly. The only calls returned was from geologist himself. Another example is they charge you for every mile that they drive... there and back. If you live in the Santa Clarita area, this might not be a big deal however being 45 minutes away in Los Angeles it became a fiscal burden that my limited project money was stressed over. Other companies I have worked with, this is included, regardless of distance. Then there is invoice / charge creep. Add surprise mileage charge and the surprise fees for every visit and your bills will grow rapidly beyond the quote. The company treats the project like there is infinite money. Of course there can be problems that require additional service, but that is part of the project. Nor was I told there may be additional costs as the project goes along. Never have I ever charge mileage for my clients, regardless of frequency. I assumed his quote was a complete picture, after all they are professional and this is not their first project. I had to, unexpectedly, take money out of my retirement to pay the bill. What I expected was a fix fee with all visits included. Not an open checkbook policy. My final disappointment was payment availability. They have no modern payment methods other than Zelle, which is a risky service. No online quickbooks payment, no Venmo, PayPal or any other modern instant service . A credit card they require you to give them your number and have it on file, where anyone can see it. If you choose to use this group, expect to pay more than what they initially quote. In the future I will go the local and hire teams experienced for my neighborhood.

Had them do a full soil report before the construction of a pool in my backyard. Not only were they…read moredifficult to work with and schedule (it was extremely hard to even get them to respond to emails and messages), they completely missed the estimate of where bedrock began by more than 10 feet. The error cost us $18k (13 extra trucks of concrete) and the worst part of the error happened exactly where they dug for the sample. I know demand is high and supply is low for these kinds of services but I was treated like they were doing me a favor by taking my money and then they absolutely botched the job.

I scheduled a consultation with Eugene from STEN Engineering to discuss two very different…read morestructural issues at my house, and I was extremely impressed. The first was figuring out how to realign a very complicated roofline so that rainwater would channel properly. The house has been built and added onto in stages over roughly 100 years, so every addition and alteration made the roofline more complicated and less cohesive. I had literally spent hours sitting on the roof trying to figure out a workable solution. Eugene looked at the situation, thought it through for about 10 minutes, and sketched out an option that simply would never have occurred to me. It was practical, elegant, and made immediate sense. The consultation was some of the best $400 I've spent. The second issue was understanding how well the house is braced for earthquakes and how the existing foundation works structurally. Again, Eugene combined a strong engineering mind with real-world practical experience and explained everything in a way that I could actually understand. I almost never take the time to write reviews, but I was impressed enough that here I am writing one. Eugene is smart, thoughtful, practical, and very good at explaining complicated structural issues in plain English. I would absolutely call him again.

It's easy to be successful when a project is easy and straightforward, but true talent and…read moreprofessionalism shines when circumstances are far from ideal and creative solutions are required. I had the pleasure of working with Dozie and his colleagues at SteelRock Engineering on a somewhat tricky project involving a retaining wall and ADU build at my home in Los Angeles, and I was incredibly impressed with their depth of knowledge, skills, their ability to pivot when necessary and make themselves available as the project required. It wasn't a quick, easy, or straightforward process, but dealing with Dozie and the SteelRock crew WAS the easy part - they were accommodating, creative in their approach when it was necessary and incredibly helpful - I don't think our project would have been successful without their involvement and I'm super grateful to have been referred to them when I was. Highly, highly recommend.

Covid really screwed up the permitting process. What used to take a day to a week, took about 3 months for a simple load bearing wall removal permit! Dozie hounded the city, immediately responded to the plan checkers requests, and kept me updated along the way. He took the initiative to keep me informed without me having to call him, and I LOVE that! It was a crappy process dealing with the city, but Dozie always made sure I knew where we stood and what we were waiting on. He had very fair pricing especially considering the extra work he had to put in dealing with the Covid delays. I can't recommend him enough! I hope im done with engineers, but if I ever need one again, he's definitely my first call!
