Structural Design
“S3DA contacted me through LinkedIn and while I am usually skeptical of cold messages, I was in need of an MEP engineer so I thought I would give them a shot. After more than a year of working on several projects with their team, I have found them to be responsive, reasonable with timelines and budgets, and willing to stand behind their work. While there are many good engineers out there, S3DA’s customer service stands out as a valuable resource.”
S3DA Design is a very critical engineering partner for us and our clients because of their attention to detail and professional relationship building skills. They have a very sincere concern for the quality of their work and satisfaction of their clients. Our company provides residential design services requiring the services of a professional structural engineering firm. We have worked with other engineering firms in the past, but S3DA Design has out performed all competitors on several fronts including pricing. But more importantly, it is S3DA’s relationship building and communication skills that have impressed me the most. They sincerely care about the quality of their work and the satisfaction of their clients. I highly recommend them and their work.
S3DA is a very conscientious engineering firm with the mindset of coming up with the best solutions for its clients that are effective and cost-efficient. I would recommend S3DA to support your structural designs on your project.
S3DA Design team are a good hard working group of professionals. They provide great communication, drawings and feedback during all aspects of the design and permitting process. I have worked with them on multiple commercial and residential projects and they always deliver in a timely manner and are priced very well. I recommend using them on any project. Their drawings are methodical and easy to understand, which makes the job easier for everyone!
I truly enjoy working with the S3DA Design team. We have completed several projects and they are professional, communicative, and expedient. They deliver good solutions quickly for a competitive price. Their work usually passes the plan check on the first submittal. I highly recommend the S3DA Design team.
My husband and I have a small architectural firm in Atlanta that specializes in transforming shipping containers and modular systems into residential and commercial projects and our "go-to" engineering firm for MEP services is S3DA. They are easy to work with, professional and provide quality work and always deliver on time. Looking forward to continuing the collaboration.
