What Our Clients Say

  • "HZS Engineering and Construction was the go-to Engineering company for my Soft story retrofit. They delivered the plans earlier than promised, with no headache. I would recommend working with this company if you're looking for efficient, easy, and reliable service. They also do construction and were very competitive with other contractor bids. I ended up working with HZS for the construction process as well."

  • "I just finished the design stage of my apartment building soft-story retrofit. The job consisted of planning/design on a two car carport area located in the City of LA. Hamid has been very easy to work with and communicated well with me. I even had them bid the construction phase and due to their price and service, I went with them. Please do yourself a favor and get a quote. For the planning, they were market rate and for the construction were well under other contractors."
