1. A computer-based method for conducting a technical assessment phase of a brownfield assessment plan, comprising: determining an optimal set of engineering tasks to be performed in said technical assessment phase; determining an optimal order for performing said optimal set of engineering tasks in said technical assessment phase; and enforcing performance of said optimal set of engineering tasks in said optimal order for subsequent technical assessment phases of subsequent brownfield assessment plans; wherein said optimal set of engineering tasks and said optimal order are determined based on expert knowledge and best practices identified from performance of previous brownfield assessment plans.
