I received quotes from a couple of companies, and while these guys weren't the cheapest, they were definitely the most knowledgeable and took the time to clearly explain how the repairs would be done. They completed the job in just two days and repaired two addional piers, and everything went smoothly. I do have a slight squeeze in one area of the floor in my raised home, and I'm currently waiting for them to come back and take a look at it. I know pier repair is not much complicated but their crew was professional and their price was reasonable. I would highly recommend these folks.

They took care of all the gov docs and got me scheduled for work three weeks after we decided to move forward. Had four quotes and Foundation Works came out in the middle and glad I went with them.

I worked with Prostruct Engineering on a residential interior wall removal project. I was very…read morepleased with their professionalism and services. The project manager, Nithin and project success associate, Joshua were always in the loop of communication. In the process, Nithin was very responsive to answer questions and make necessary drawing changes according to the requests. The project was done in a timely manner with reasonable cost. Overall I was impressed with their performance, quality, schedule and cost!

They were gracious enough to fully refund our payment. They were very understanding, and we will work with them in the future if the need arises.

I would recommend Arthur to anyone as good business deserves more business!…read more We are new to our condo and were easily intimidated by our HOA board cause we wanted to open up our kitchen by 5 feet! They required an approval of a licensed Structural Engineer before we could begin any work. I called around but liked speaking to Arthur who was very knowledgeable on the phone and was willing to work with my schedule to inspect the property asap. He was very punctual and courteous all in all Arthur is AWSOME, his knowledge & demeanor is very professional and patient. He takes the time to fully understand the issues and pain points that as a new homeowner helps quite a bit. He has approved our plans and will send the desired letter in order to continue our renovation.

I found Sam through Yelp. At first, we were both not sure whether we will work together because he…read morelives more than 20 miles away from where I live, and I'm the type of person who is always skeptical about what I read on the internet. But now I'm very happy that Sam decided to take on the job and develop the structural calculations and drawings for removing a load bearing and shear wall at my Condo. The Project started in September 2025 with initial submittal of permit application package to the City. It went into construction about four (4) weeks ago and was successfully completed today (5/8). During the process, we developed trust for each other. I contacted Sam numerous times for questions, problems and consultations and he was always responsive. He and my architect friend worked together to develop the initial design but had to modify it to overcome a major obstacle that came up during the construction. He came over for construction observations and gave instructions to the contractor how to strap the beams together for maintaining structural integrity of loading and shearing. His fees were much lower than another builder whom I also got a bid from, and his approach to things was much simpler and yet conservative to that from the other firm. I told Sam, whether it is good or bad, I don't usually do reviews for others. But for him, I will do one. I'm thankful to have a great team of Sam (the engineer), my architect friend, and excellent construction crew to help me complete this project.

Sam is awesome. I had significant concerns about the house I had just bought because the floors…read morewere uneven and there were cracks in the walls. Sammy came and addressed each concern that I had and assessed the crawlspace. He gave me so much helpful information and explained everything carefully, even drew diagrams! You can tell that he cares about his clients and their safety. He is also very personable and makes light jokes! In total, my experience was very positive and while there is work to be done on my house, I have more peace of mind now.

Outstanding responsiveness and professionalism. I reached out to Marshall GeoScience through Yelp…read more Marshall (the principal engineer) replied quickly--even continuing the conversation well after business hours and offering to jump on a call. I wasn't exactly sure what I needed at first, and he was incredibly patient while I tried to explain the situation. Rather than guessing, he took the time to understand my goals, clarified that a firm estimate would require a defined scope of work, and laid out what that scope should look like so I could move forward confidently. What stood out most was his clear communication, transparency, and willingness to help without any pressure. I'd contacted a few other firms before him and had mixed results. Marshall was by far the most responsive and helpful. If you need a geotechnical engineer who is prompt, thoughtful, and genuinely focused on setting you up for success, I highly recommend Marshall GeoScience.

Live in Santa Monica and our city planning department had a very unusual request for a soil…read moreengineering report that is not your typical report. I contacted a substantial number of other soil engineers who: -Didn't understand the request. -Said it was too small for them. -Were too busy. -Never responded. -Insisted on doing a massive (EXPENSIVE) report. One firm - Marshall - responded immediately, took the time to review the plans in detail, called the city, and got specific needs. He immediately came out, did the site inspection and within a week had a full report. And at a very reasonable cost. I cannot recommend Marshall GeoScience more highly -- exceptionally professional and willing to go the extra mile!

The transition is always smooth. When Evgeny tells you he will get the plans done by a certain date he meets that deadline.

I would recommend STEN Engineering!

He came and inspected our roof, as we were planning to install solar panels with Tesla. However, Tesla refused to provide a 100% offset and only offered 66%, claiming that there were issues with our roof.

We 100% recommend him!

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.

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
