CSX Camden Street Storm Drain Replacement (MD)

The CSX Camden Street Storm Drain Replacement was a technically complex, design-build project located in a heavily traveled section of downtown Baltimore, Maryland, which consisted of replacing a 48-inch-diameter brick storm drain, originally built in 1891, that crosses directly under the CSX railroad tracks in the Howard Street Tunnel.

Riverbend WRP Expansion (TX)

Upper Trinity Regional Water District’s (UTRWD) Riverbend Water Reclamation Plant (WRP) needed to increase its capacity from 2 mgd annual average daily flow to 4 mgd with a peak flow rate of 16 mgd. Carollo evaluated the existing capacity of the plant and planned the facility expansions through 2040. With project drivers determining that construction management at-risk would be the best delivery method, UTRWD chose Archer Western as their CMAR.

Cutter Lateral Reach 21 Water Treatment Plant & Conveyance Pipelines (NM)

Water in the Four Corners region is in short supply for many communities and available water is often of poor quality. In order to mitigate water contamination and scarcity, the Navajo-Gallup Water Supply Project was conceived, and a significant portion of the project, the Cutter Lateral, is near completion in Summer 2020. Multiple state and federal agencies are involved with this massive project.

Witchita Water ASR II (KS)

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.

Ashland Storage Basin Replacement (CO)

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.

North Lee County Water Treatment Plant Rehabilitation and Expansion

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.

Westerly Wastewater Treatment Plant Centrifuge Replacement (OH)

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.

Edward W. Bailey Water Treatment Plant (CO)

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.
