This challenging Construction Manager at Risk project performed for two Phoenix suburbs involved major roadway construction in a high-traffic area. Sundt widened 67th Avenue at three major intersections in the cities of Glendale and Peoria and installed nearly 12,000 linear feet of storm drainpipe down the center of the busy roadway. Crews also installed new street lighting, median islands, storm drains, traffic signals, signage, landscaping and sidewalks. Sundt also converted the open trench irrigation to underground pipe, placed the overhead electric power underground, upgraded street lighting and replaced aging water lines.
The team constantly looked for ways to save the City of Glendale time and money, in addition to minimizing disruption to the traffic flow. One example included the replacement of large diameter storm drainpipe with smaller diameters depending on storm water flow. The original design called for 60- and 66-inch pipe diameters throughout the entire project. The team reduced the storm drainpipe sizes depending on the location and the normal gravitational flow. This saved the City $1 million and lessened the effect on traffic by requiring a shallower and narrower pipe installation trench.
