Simplengi Engineering - Berkeley, California

I've worked with David Yadegar and his team on several complex projects. For a builder, working with his team is a pleasure. They keep the builder in mind when designing projects and are always readily available to answer questions and make site visits. I would highly recommend them any project.

As a general contractor working on residential remodels, we frequently work with and have good relationships with a number of structural engineers. When it came to working on my own home, I chose to work with David. He's knowledgeable, quick to respond to questions and changes and very easy to work with. I couldn't recommend him more highly.

I have hired Simplengi on multiple projects over the past several years. I have used them on many seismic upgrade projects as well as foundation projects for multi family units. They have evaluated large commercial properties and they have provided solutions for tenant improvement work. They are experienced, efficient and professional. They work well with contractors and they are quick to adapt to onsite challenges and changes. Their team is a joy to work with and I highly recommend them.

David helped clarify a lot of the differing and ambiguous information that is out there for Berkeley home owners looking to do seismic upgrades as part of the transfer tax rebate. After connecting over email David made a personal house call to determine scope and scale of any necessary work. He actually found that my foundation was fairly recently upgraded, and suggested not doing a costly upgrade as any costs would likely outweigh the benefits. I found David to be extremely knowledgable, approachable, and honest. Highly recommend.

I am an architectural designer who has worked with numerous structural engineers over the years. That being said, David is by far the best I've ever come across.

First off, David is approachable and empathetic. David is not only interested in giving you good drawings and calculations, he is interested in the quality of his relationship with others. As a designer, I feel open to asking him any question because he doesn't give me a look like, "What, you don't know that?!" Instead, he is huge on establishing rapport, speaking in simple, easy to understand terms, and making things go smoother for everyone, including the client, contractors, and designers.

He also doesn't oversize beams just to make things easier for him as some of my past engineers have done. As one who truly cares for the well being of his clients and the planet, he does the calculations to know exactly what size is needed without wasting unnecessary money or material.

As a contractor recently said to me after the three of us met on a job site, "That dude's awesome! I've never met an engineer like that." What more can I say?

We consulted with David before we recently purchased a house. Because the house was a "contractor flip", we wanted to feel confident about the quality of the work that was done. On very short notice, David made time for us so that we could schedule his visit in tandem with the regular home inspector that was scheduled to come.

David was fantastic! Knowledgable, easy to talk to, and thorough, he not only gave us his assessment of the place, but also collaborated with the home inspector to make sure nothing was missed. We were so happy he was there.

We cannot recommend him highly enough. If you need some structural engineering contracting done, definitely call David.

I have know David for a long time. He is a pleasure to work with and provides excellent and creative service.

As an architect it was a no brainer to reach out to Simplengi when the time came to remodel my own home.
