It's been a pleasure working with David & Gayane at Biayna Engineering. They performed a Soft Story Retrofit for a 1960s multifamily building. Much like all construction, there are always issues that arise. They took care of all the issues, and the installation was quick and professional. Not to mention their price was good and communication was spot on. The only experience I have with David and his team is Soft…

Great experience. Very fair price. They really put the customer first. I would confidently recommend Biayna. David is knowledgable, patient, and took care of my detailed requests.

On more than one occasion David and his team went out of their way to make sure I was satisfied with all the…

I had four companies come out to evaluate a major structural foundation issue on my hillside property but they either didn't want to take it or could not figure it out.

Even the city inspector was impressed at the structural engineering design. Lucky to have found them.

David Muradyan, a USC graduate structural engineer, and the supportive staff there are a group of dedicated, hard working and helpful professionals. Prior to making a decision I visited them and found an active office and felt easy that I could…
