I contacted the engineering group at MKM and was put in contact with Nick Stuart. Nick came out and did a site visit and then worked with a designer to work on a voluntary repair plan to better support my foundation and wall. The experience while working with him was great. He was very responsive, kept to a schedule and came in at the budgeted amount forecasted for the work. He even did above and beyond items, dropping copy of plans off to me while I was at the permit office! I would absolutely recommend them in the future and plan to work with them again on a second unit in the upcoming months. They are extremely professional, have a great work ethic and do a great job!

Working with Irvin at Prostruct Engineering was a breath of fresh air. After purchasing a new home…read moreand enduring my first winter, I was incredibly nervous to find significant water in my crawl space and cracks along the raised foundation. I initially signed a contract with Prostruct, but after Irvin reviewed my photos, he demonstrated a level of integrity that is rare to find. Instead of taking the job, he honestly informed me that my specific issues fell outside their scope. He took the time to explain what I was seeing, referred me to a geotechnical engineer who could actually solve the problem, and issued me a full refund. I greatly appreciated his transparency and professional guidance. I highly recommend Prostruct Engineering to anyone looking for an honest assessment--they clearly prioritize the customer's needs over their own bottom line.

Their team is very professional, responsive, and easy to work with. The plans were well-prepared and detailed, and the city approved them with minimal corrections, which really speaks about their quality and attention to detail. One of the projects was on a hillside property, where the foundation requirements were quite intense, but their team handled it seamlessly with well-thought-out and detailed designs. See pics. They always delivered on time and maintained excellent communication throughout the process, keeping me informed at every step. I highly recommend ProStruct Engineering to anyone looking for reliable and efficient structural design services! A special mention to Lokesh, who I worked with directly -- he was very responsive, understood my needs clearly, and made sure everything was addressed on time.

I hired A1F1 for a small project first (removing two columns in the front of my house to make a…read morenice sit-down patio). 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.
