Computerized scheduling techniques are used throughout the Pre-Construction and Construction Phases of a project. During Pre-Construction, key milestones, design and specification requirements, and long lead procurement items will be identified and incorporated into the progress schedule. This information will be carefully coordinated with completion deadlines and design document requirements. Establishing a CPM Schedule is not merely a function of developing a computer generated critical path document, rather, it is the ability to determine the timing of critical decisions to be made. It also indicates the interrelationships that exist in all design and construction processes.
