ACEC Engineering Excellence 2017: 90-Inch Water Main Hot Tap & Line Plug in Des Plaines, IL

Posted by Infra on Monday, July 17th, 2017

2017 ACEC Engineering Excellence Awards

GRAEF and TDW Services, Inc., of Chicago, IL has earned an Honor Award for exemplary engineering achievement in the American Council of Engineering Companies’ (ACEC) 50th annual Engineering Excellence Awards (EEA) for the 90-Inch Water Main Hot Tap & Line Plug in Des Plaines, IL.

A colossal 90-inch water transmission main was completely relocated to accommodate the rebuilding of the Jane Addams Memorial Tollway, while incredibly maintaining water service to 500,000 residents. The project team designed, tested, and constructed a unique thrust restraining system to absorb the massive forces generated by the risky hot tap procedure—where two pipes are connected without emptying pipe contents. The system safely absorbed the high pressure force when water was diverted into the bypass section. It allowed a critical water supply to be preserved, the construction schedule to be reduced by a year, and renovation of the Tollway to proceed.
