Absolutely top-tier service I worked with this company on a house project in Hollywood and I can't…read morerecommend them enough. from the very first consultation they were professional, knowledgeable, and incredibly responsive. What stood out the most was how house solution oriented they were. they didn't just follow the typical playbook, they took the time to understand the specifics of the property and proposed smarter more efficient options that ended up saving me a significant amount of money without cutting any corners on quality or safety. Every step of the way the communication was clear, the timelines were realistic, and the work was done with precision. It's rare to find a team that combines technical expertise with this level of integrity and client care. if you're doing any type of structural work especially in LA, I highly recommend giving them a call. Good total pros

Ilya Engineering responds to emails within minutes and answers their phones. Surprisingly, once an…read moreengineer is assigned to your project you can contact him/her directly. 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

I felt it was important to share our experience with JZ structural as I ultimately went with them…read moregiven their high Yelp reviews. However, my experience was negative to say the least. Ellen was responsive initially, but this was only until they received payment. After this, trying to get a response was like getting blood from a stone: close to impossible. My architect had asked Julian, the engineer, if he could draw a rough mock up before he put together a full set of plans (to which he agreed). We never got this, despite checking in multiple times, and instead, it was only right upon the 'deadline' we had provided for the project that we received a full final set of plans. This was disappointing. The plans themselves were riddled with errors: it seemed like a lot of copy / paste work rather than careful attention to detail. The wrong county was listed, and certain structural details were copy pasted from the wrong city, which my architect had to point out. We had around 30 local contractors look at the plans, as well as two peer reviews of the plans from other licensed structural engineers, and the feedback was that it had been over-designed (consistent with one of the other yelp reviews). After multiple emails attempting to get Julian (the engineer) on a call, he was incredibly defensive, and rude. It was at this point, I was appalled that he would speak to a client like this, so decided to cut ties with this company and use another structural engineer instead. If you are in absolutely no rush, and have no concerns about over-design: perhaps this company will work for you. But for our residential project, this was one of the worst experiences I have had with a "professional" service, and I want to warn others.

Working with Ellen, Julian, and others from JZ Structural was great. They were extremely…read moreresponsive. They also diligently worked with the city, project manager, and other contractors to get the job done. Ellen and Julian also provided a very personal touch with guidance in hiring contractors, materials to use for the project, and design. They explained everything to us in detail and were always available to answer any questions and address our concerns. Overall, JZ Structural provided us with a great experience. Would highly recommend getting in touch with them if you need help with building and large renovation projects.

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.

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!

Their team assisted in resolving b-permit issues, plan checks, zoning administrator filings and more. Their knowledge and experience was critical to solving the many problems this project had being a broken development in the city of Los Angeles. Our permit expediter said we wouldn't have gotten building permits without Bryan Lopez's knowledgeable and firm handling of the LA plan checker on our last set of permits. Since the scope of the project was difficult to define, we mostly worked on a T&M basis. The billings were always reasonable based on the work being done. Also, the team was always responsive to our needs and deadlines. These guys are trustworthy professionals and can handle the most challenging projects.
