On January 16, 2018, the Fox Waterway Agency (FWA) was awarded the 2018 APWA Lake Branch Chapter Project of the Year for Structures - Less Than $5 Million for their Foundation Modification and Office Renovations Project. More recently, the FWA was also awarded the 2018 APWA Chicago Metro Chapter Project of the Year award in the same category. To accept and celebrate the award, on Friday, March 16, 2018, Trotter and Associates, Inc. (TAI) attended the APWA Chicago Metro Chapter Awards Luncheon with representatives from the Fox Waterway Agency, Gillespie Design Group, Schmidt Engineering, Inc., and Carmichael Construction Inc.

By recognizing professional contributions, public works professionals promote an atmosphere of mutual respect and provide a way to grow and achieve. We would like to thank everyone involved in the project, APWA and the awards committee, for the recognition.

It was decided that the best course of action would be to replace the seized gate valves with AWWA butterfly valves (which would be less likely to become fouled by mussels in the future). It is important to note that the shutdown required for replacement had to be as short as possible in order to restore flow of cooling water to the major industrial user's manufacturing process.
