“I most certainly would work with S3DA-Design again. My experience was great with them, I thought it was a total team approach, I thought all the individuals were great in getting the information out, the request for information to be able to build the building, the budget, the whole process just was very well orchestrated by S3DA-Design. I honestly don’t know how you could have done it any better, I appreciate all of your time, help, and willingness to drop everything and come to the site, talk to me and make sure that my concerns were met, and deal with, and I thought it was a pleasure dealing with everyone in your team.”

“I am very pleased to write this letter of recommendation for S3DA-Design’s structural engineers. During the period of H1, 17, I have been able to closely interact with them on a complicated building package consisting of both structural & construction drawings for an important new build development. I have observed their capability to quickly grasp the concepts I have in mind and efficiently implement the same to solve the engineering needs of the project. their rational thinking and ability to address all points of clarity is impressive and so I have no hesitation in providing this recommendation for them.”
