In december 1990, Sundt Corp. tackled a formidable construction project - Reach IV of the Arizona Canal Diversion Channel (ACDC). The task: To build the final 4.6-mile section of a new, 40-foot-wide, 24-foot-deep concrete drainage channel in Phoenix. In October 1993, after nearly three years of hard work, Sundt completed its mission. The company also garnered the applause of its peers, as it won the 1993 Build America Award from the Associated General Contractors of America, the 1994 Contractor of the Year award from the American Public Works Association, and the National Excellence in Construction Award from the Associated Builders and Contractors.

The location of the ACDC-Reach IV created four major challenges for Sundt. All four stemmed from the project's most vexing problem - its virtual inaccessibility. The ACDC runs parallel to the north side of the Arizona Canal. After excavation proceeded below grade, there was just one lane between the north side of the canal and the south side of the drainage channel. Existing power lines limited overhead work, and Sundt couldn't even reach the north bank because of area homes and businesses. The confined area dictated Sundt's agenda:

  • To minimize community friction
  • To coordinate work flow and devise cost-saving changes
  • To customize construction equipment
