Our services include: Structural design for load-bearing wall removals, remodels, additions, decks, retaining walls, and foundations. Civil/site plans for grading, drainage, right-of-way permits, stormwater design (WWHM 2012, SWPPP), and utility coordination. Land development services including subdivisions, short plats, and lot line adjustments. Permit support and coordination with local cities and counties.

Our experience was absolutely first-rate: we received crucially valuable information and inventive ideas, fully and clearly expressed.The engineer met with our contractor, regarding a garage rdemodel--raising the floor more than two feet and reconfiguring a space of 625 sq. ft. Brilliant, cost-effective and comprehensive solutions!

Mr. Ebrahimi responded promptly following my initial inquiry on Thumbtack. We had an in depth discussion regarding my project over the phone after providing some rudimentary pictures and information. He seemed to go out of his way to help me remotely and find time to accommodate my schedule within a week. His on-site review and discussion of the project was thorough and straightforward. Would recommend his services to anyone seeking structural and whole-view expertise.

The engineer explained everything clearly. He let us know what steps to take to fix our drainage problem and how to fix the hole under our backyard art studio. His recommendation was more reasonably priced than the other guys solution. And he showed us why the less expensive route would work better for our situation. We trust him and would hire him again for any engineering we may need in the future. He was pleasant to work with as well.

I had such a great experience working with Morteza! He came by to inspect the structural aspect of a wall and he was super professional, on time, and easy to talk to. He explained everything really clearly and made sure I understood what was possible structurally before moving forward. What I really appreciated was how helpful and down-to-earth he was — he didn’t just do the inspection and leave; he offered advice for a few other projects I have going on in my home and even pointed me in the right direction with inspectors, electricians, etc. It’s so nice to work with someone who genuinely cares about helping you get things done the right way. I’ll definitely be calling him again for future projects. Highly recommend if you’re looking for someone knowledgeable, reliable, and just overall great to work with!
