Had been recommended a particular engineer from SSW for our major landscaping project to do the designs for. Michael Cox, initially came and gave a good amount of information, and seemed to know precisely what to do. This gave us confidence to go ahead and use him as our engineer. He had a few plans supposedly that was ahead of are but gave a generalized timeline for when he expected to be done. His initial communication was mediocre at best but he let us know when he was expecting to work on the plans.
But when his time frame came and went, it took several emails spread out through a couple of weeks before he responded again, with another timeframe. Which once again came and went with no response as to why the delays. When we tried to get in contact with him again, we even brought up our concerns with the significant delays in communication, which he did acknowledge but after that email, we never got anything else. Weeks went by, again no updates, no idea of why our project designs werent being done.
We started emailing weekly, calling and leaving voicemails, but nothing. Even had our landscaping company try to reach out, because our project was dependent on his plans and design. This has been an utter nightmare and unfortunately has reflected horrifically on this company. This has put us in a difficult position, for our project has now been delayed to a point that puts in the rain season with no retaining wall to protect our house from mudslides.
We gave him ample time and multiple opportunities to keep us as clients, but has burned that bridge permanently and we will not be using him or the company that would stand for this type of extremely poor communication.

Very helpful! I called about getting a boundary survey done on a new property. Turns out they had done one for the previous owner 3 years earlier. They emailed me the survey map and I was able to easily find the markers they had set previously.

Amazing! These guys are TOP NOTCH. Very professional, knowledgeable, and they do what they say they're going to do when they say they're going to do it. They're super busy just like everyone else in the industry, but they got me scheduled within a few weeks (vs a few months like the local firms here had quoted). They came out to Florence and did two properties on the same day to help with time and money.
The guys who did the work here could not have been nicer, they were more than willing to walk me through both properties. I'll for sure be using them again in the future. I couldn't recommend them more and I hope they thrive! We need more quality businesses like SSW around here.

Highly recommend SSW Engineers, especially Jason G. who was VERY helpful and responsive. They helped us with our site plan for our Conditional Use Permit with the city for my business, Central Bark doggy daycare, and any time we needed an update/change to the site plan to meet the city requirements Jason was able to turn around the changes quickly and without issue. Thank you!

I have worked with the surveyors and engineers at SSW Engineers Inc for more than five years. Each of the projects that SSW Engineers has undertaken both for me personally and for my business have been performed on time, within budget and have been performed to the highest standards. Mike Dahrens, PLS, the lead surveyor has done general surveying, forensic surveying and has provided expert testimony in several extremely complex lawsuits.
I credit our success in these matters in major part to Mike's skill, breadth of experience and effectiveness in his representation of his clients. I offer my highest recommendation of Mike Dahrens and the staff at SSW Engineers Inc and would be pleased to discuss my recommendation personally with prospective clients.

SSW Engineers has handled virtually all of our structural and civil engineering projects for many years. This included the survey work, conceptual building designs and site plans, and land use planning, for the new construction and remodels of all our stores and warehouses. We feel they are the best at what they do.

McKay Investment Company has been blessed with years of exceptional and professional service from SSW Engineers Inc. They have proven time and time again to be a necessary and integral team member of our development team. We have been fortunate to have them our exclusive engineering firm of our new development and redevelopment projects and it is with absolute confidence that I recommend their services to others.
