This wastewater treatment rehabilitation project significantly upgraded the City’s Water Restoration Plant to improve reliability of treatment. The progressive design-build team worked collaboratively with the City to implement improvements at the existing facility, while maintaining operations throughout the invasive construction activity. The project touched almost every aspect of the facility, including modifications and replacements of existing control systems and basins. The new SCADA system also enhances operation and provides staff with comprehensive operational data and opportunities to optimize system performance.

A Case Study in Progressive Design-Build

Being a Progressive Design-Build project, the team’s approach focused on minimizing cost, reducing risk, streamlining construction and improving schedule performance. Utilizing the capabilities of all team members was critical to maintaining operation of the facility throughout construction and maximizing project value within the City’s limited budget. The City had established a project budget but quickly recognized the value in increasing the project scope to address critical improvements that had not been fully identified as part of the previous planning effort. Relying on continuous estimates during design and with creative uses of allowances, the City continually prioritized improvements to gain as much value as possible from their investment. The teams’ collaborative approach allowed realization of the common goal of a continuously functioning plant, appropriate infrastructure, and flexibility when problems arose.
