If you are looking for an authority on retaining walls, this is the guy. Joe has helped my company on many projects.Joe Kowalski analyzes situations like no one I have ever seen. He comes at a project with the straight forward, level headed approach you would expect from an engineer, but Joe is very creative in finding solutions to problems that most engineers would never take the time and effort to explore. He does this through engineering, material implementation...Bottom line: Joe will offer multiple solutions to a problem. All the engineers I have worked with in the past take a 1 size fits all approach. Joe goes out of his way to show you where you can make it better, both in engineering and cost.I highly recommend Joe Kowalski! He has saved my company hundreds of thousands of dollars.Thanks Joe! Keep up the great work!
