Design-Build for New Versus Retrofitting Water Treatment Plants
CONTENT EXPIRES: December 31, 2023
Design-build is gaining traction and becoming an increasingly popular delivery method for water infrastructure projects. Whereas the design-build advantages historically focused on greenfield projects, this delivery method can also be extremely beneficial for retrofits of existing facilities. This presentation will explore the merits of design-build for water treatment plants and will highlight two Indiana American Water treatment plant projects, one retrofit and one greenfield, that demonstrate the advantages of the delivery method and highlight customized approaches to meet the owner and project needs.
1. Demonstrate the advantages of design-build for greenfield projects and less conventional retrofit projects.
2. Compare the design-build benefits for greenfield and retrofit projects.
3. Explore the challenges with retrofit projects and how a design build team can work through the challenges collaboratively.
4. Assess complications for project closeout amidst COIVD.
