The City of Wichita’s ability to obtain adequate drinking water was threatened because their main source of water had become depleted and vulnerable to saltwater intrusion. To improve both the quantity and quality of available drinking water for the region, the City of Wichita’s Aquifer Storage and Recovery (ASR) project draws water from the Little Arkansas River during high flows, treats the water to drinking water standards, and then injects the treated water into the aquifer for recovery and use during drought conditions.

To solve water loss issues and reduce operation and maintenance costs, Denver Water solicited the services of a construction manager at-risk (CMAR) to remove and replace the existing Ashland Storage Basin Facility, located in the historic Highlands neighborhood, which was originally constructed in the 1890s as an open-air reservoir with earthen bottoms.

Using the progressive design-build delivery method provided $1.6 million in value engineering savings. Carollo’s design for the project reduced operating costs for Lee County Utilities by as much as $784,000 per year. This project was substantially completed on schedule and was awarded the 2012 Florida Section Design- Build Institute of America (DBIA) Award for water/wastewater projects.

NEORSD’s decision to use progressive design-build (PDB) project delivery was based on the need to move more quickly, save money, and promote collaboration – resulting in a better approach than possible with traditional design-bid-build (DBB). PDB also gave NEORSD full insight into the cost of the work to be done throughout the project.

In 2014 the city of Centerton began experiencing an unexpected growth spurt, almost doubling its size, forcing the City of Decatur to research wastewater treatment plant expansion options to accommodate the population growth.
Project Year: 2016-2019
McCarthy Building Companies and Carollo Engineers partnered on the Edward W. Bailey Water Treatment Plant and brought forth a unique approach to the project. The original project plan called for a campus style layout. The McCarthy/ Carollo team developed a plan that would consolidate the treatment structures and limit the plant’s exposure to the
poor soil conditions.

The partnership between Burns & McDonnell, Garney Construction, and the District during all aspects of design and construction was vital to this project’s success. The accelerated project schedule would not have been possible without using a design-build approach. This type of partnership allowed for flexibility and more collaboration than a traditional approach.

The City of Houston, Texas, in association with four regional water authorities, is expanding its Northeast Water Purification Plant, dramatically increasing its ability to support steady residential and commercial growth while reducing dependency on groundwater. Construction is currently underway on this 90-acre site, the largest progressive design-build project of its kind in the United States.

In recent years, the town of Stonington’s wastewater infrastructure had begun to show its age. Odor-control issues and adverse press reporting, as well as state regulations on nitrogen levels in effluent and the rate of commercial and community growth all placed strain on the town’s Mystic, Borough, and Pawcatuck water pollution control facilities. Since they were located near residential, commercial, and cultural sites, there was no available real estate to expand or build a new facility.
