Dennis Postler, PE, has been named Vice President of the Municipal Services Division at TKDA.
Postler has worked for 30 years in municipal engineering, serving clients in Minnesota, Wisconsin, and California. At TKDA, he takes over a growing division that provides general city engineering services, roadway and public utility design, surveying, planning, transportation studies, and water and wastewater systems for municipalities, agencies, and industrial clients.
“I am proud to take this leadership position at TKDA,” Postler said. “Our team strives to build long-term relationships with our clients, and they trust us to provide on-going, quality services. While we are committed to our broad base of existing clients, our future includes expanding our services into new markets.”
Prior to joining TKDA in 2014, Postler held key leadership positions in other regional engineering firms where he focused on client service, operations, growth strategies, and staff development. At TKDA, he plans to add key leadership positions with expertise in identifying growth markets.
TKDA and MnDOT were presented with a 2015 Engineering Excellence Honor Award for the Elk Run Interchange project at the recent American Council of Engineering Companies of Minnesota (ACEC/MN) banquet in Minneapolis.
TKDA was MnDOT’s lead design engineer on the project, which was completed in November 2013. TKDA designed one of Minnesota’s first Diverging Diamond Interchanges (DDI) as the centerpiece of the Elk Run Interchange along Trunk Highway 52 just outside of Rochester. This innovative design alternative accommodates higher traffic volumes than a traditional diamond interchange while offering increased safety, traffic calming, simple two-phase signal operation and easy access for pedestrians and bicyclists. The new Elk Run Interchange minimizes conflicts and modifies traditional traffic flows to improve turning efficiencies. The DDI design also eliminates the need for large interchange loops, which resulted in a shorter bridge length and smaller environmental footprint. The interchange and the connecting county roadway improvements are the latest phase of MnDOT’s efforts to upgrade TH 52 to a fully access-controlled freeway between Rochester and the Twin Cities.
Several members of the TKDA Municipal team will be sharing their expertise at this week’s City Engineers Association of Minnesota’s 2015 Annual Conference in Brooklyn Center.
On Wednesday, Brad Hammerquist, PE, senior registered engineer, will be part of the Trenchless Technologies Buffet session. He will discuss the applicability of the slip line pipe rehabilitation method and how TKDA designed slip linings with fiberglass reinforced pipe for 1.7 miles of the City of St. Cloud’s sewer interceptor system during the last year’s successful rehabilitation project. Our own Jim Studenski, PE, a senior registered engineer, will moderate this session.
On Thursday, Jim Studenski will moderate a session on MN 2050, with colleague Tom Eggum, a senior TKDA consultant, presenting on the efforts to educate Minnesotans on the importance of investing in public infrastructure. MN 2050 is an engineering-led effort that began in 2009 and this session update conference participants on the program’s impact, progress and ways to get involved.
The conference will be held at the Earle Brown Heritage Center Wednesday through Friday. For a complete list of presentations at CEAM 2015, log on to http://goo.gl/YG8BjC
