Pipe Rehabilitation at Kansas City Airport

Aegion subsidiary Insituform Technologies, LLC completed a major pressure pipe rehabilitation project at Kansas City International Airport (KCI) north of Kansas City, Missouri during the winter of 2011 - 2012.  The project consisted of approximately 690 lf of 12-inch and 4,840 lf of 16-inch steel pipe.  Installed in the early 1970s, the original chiller system required rehabilitation due to numerous breaks and degradation due to age.

The mains, used to carry chilled water from cooling towers into airport terminals, start at the airport control tower and run along the roadway and through paved parking areas to the three individual terminals. In addition to concerns about traffic disruption, KCI did not want to lose the parking revenue due to the extended time frame open-cut replacement would cause. Thus, a cured-in-place pipe (CIPP) rehabilitation option was selected. 

Insituform’s fiber-reinforced cured-in-place pipe (CIPP) product for potable pressure pipes, known commercially as InsituMain®, was used to rehabilitate the existing pipe and provide a structural solution. Project consultants Burns & McDonnell and VSM Consultants served as design partners on the project along with Insituform.

The project had to be completed during the winter months due to the chiller and air conditioning requirements of the three airport terminals. The system went “offline” October 31, 2011. Cleaning and CCTV of the lines followed with CIPP installations in December 2011 and January 2012.

Project challenges included the absence of any “as-built” information for the existing piping system and multiple 45° horizontal pipe bends. The project was successfully completed ahead of schedule, with no airport shutdowns and minimal parking and roadway disruptions.
