    4. Overall Project Objective Develop a decision tool: To help analyze different alternatives with multi-level criteria To determine which construction method for a specific bridge project is preferred To compare conventional and accelerated construction methods The overall project objective in developing a decision tool is to do the following: To help states analyze different alternatives with multi-level criteria and sub-criteria To determine which construction approach for a specific bridge project is preferred To compare conventional and accelerated construction methods The overall project objective in developing a decision tool is to do the following: To help states analyze different alternatives with multi-level criteria and sub-criteria To determine which construction approach for a specific bridge project is preferred To compare conventional and accelerated construction methods

    5. Project Goals and Target Users Goals of Project Bring ABC to ordinary (bread and butter) bridges Create a tool that can communicate decision rationale Assists users in making ABC a standard practice Target User Population Project managers Project Engineers and designers Project owners Program planners Although we have been hearing the use of ABC for big and special projects at large, we want to bring ABC to ordinary (bread and butter) bridges. We also want to create a tool that can communicate the decision rationale. It is our vision to assist users in making ABC a standard practice. As such, we designed this tool for project managers, project engineers, project owners and program planners.Although we have been hearing the use of ABC for big and special projects at large, we want to bring ABC to ordinary (bread and butter) bridges.

    6. Criteria Organization The first thing the TAC members did was to identify the criteria typically found in making project decision. After several hours of deliberation and iterations, the team came up with these criteria. There are five main criteria identified across the top; i.e., schedule constraints, indirect cost, direct cost, site constraint, and customer service. Under each of the five main criteria, we divide into sub-criteria, 3 for SC, 6 for IC, 9 for DC, 5 for SC and 2 for CS. The team believes that this is a well defined list and probably has more criteria than a typical project would require. So far from the projects used in the testing and validation, we have not found any new criteria that are missing yet. On the contrary, we have deleted or removed some of the criteria that were not applicable. The first thing the TAC members did was to identify the criteria typically found in making project decision.
