With these sizes, projects like Echo Water in Sacremento can take a decade before they are completed. So how to engineers, contractors, designers, utilities and their stakeholders keep everything straight?

Strauder Patton, national program leader for program management for Brown and Caldwell, and Graham Calciano, Brown and Caldwell joint venture leader of the Echo Water project, talk about the tools and technologies that have made these large scale projects possible, and the challenges they face that smaller ones do not.
