Bernie Ysursa, Vice President , Southwestern Illinois College, Belleville, IL

“TWM provided a timely 6-week turnaround for the re-design and evaluation of over 100 ramps on a fast-paced project.  They were open to comments and suggestions from the City as they designed the ramps, which is a wonderful quality.”

Megan Fuhler, PE, Director of Public Works, Village of Shiloh, IL

“TWM completed Dapron Drive within a very short timeline, allowing construction to proceed the same calendar year as the design.  They are a capable firm big enough for major projects, but small enough to react quickly to client requests.” 

Tim Gregowicz, PE, City Engineer, City of Belleville, IL

“TWM provided thorough, timely engineering services every step of the way. Their accurate plans were easily constructed in the field.  TWM staff worked right alongside our City Engineer as well as all our staff and IDOT’s.  They kept the project going by reacting quickly with changes, always keeping our needs at the forefront of the design.”
