Project: Tomahawk Creek Wastewater Treatment Facility ExpansionLocated in Leawood, Kansas, the Tomahawk Creek Wastewater Treatment Facility began operation in 1955 with numerous expansions and upgrades over the years. The $270 million expansion project included more than 30 new structures, more than 130 installed pumps, three-tower cranes, 50,000 cubic yards of concrete, more than nine miles of underground utilities and 792 deep foundation drilled shafts. Construction began in 2018. The project was completed on schedule and on budget in May 2022.

The Tomahawk Creek WWTF was a joint project of Johnson County Wastewater, McCarthy Building Companies-Kansas City, Black & Veatch and HDR. Due to the complexity and tight schedule, Johnson County chose to use the collaborative delivery method of Construction Manager at Risk (CMAR).
