CPM Scheduling & Sched Analysis

Time Impact Analysis (TIA®)

Critical Path Method (CPM) schedules and formalized methods of analyzing schedule impacts started to enter mainstream construction management practice in the early 1980’s. At that time, the industry recognized a need to accurately and scientifically measure schedule delays and conversely the affects of acceleration in real time during construction and also retrospectively after the work was completed. The ability to determine which party ultimately bore responsibility for schedule delays became the main focus on many projects as the assessment of liquidated damages or granting compensable time extensions became critically important to both owners and contractors. Just as the Rosetta Stone provided scholars with a means to translate Egyptian hieroglyphics into Greek text, Time Impact Analysis (TIA®) provides users with the means to translate Critical Path Method (CPM) activities into understandable schedule impacts.

Recently, MDC Systems® made the jump from Primavera P3 (version 3.1) to P6.

This is in addition to the learning curve for the new features and capabilities of P6.

For some types of projects it is easy to anticipate where the critical path should be;  for instance in high-rise building construction, the critical path is most likely to be: excavation, foundation, structure, weather enclosure (building envelope), MEP, finish activities.

Risk Reduction with Effective Critical Path Method (CPM) Schedules

The purpose of the Critical Path Method (CPM) schedule (A scheduling technique whose order and duration of a sequence of task activities directly affect the completion date of a project)is to assist in the cost effective management of the project, anticipate problem areas, and allow the project team to mitigate the impact of unforeseen conditions. What a tool! Without this tool, the project management team is simply reacting to a crisis of the moment and their hurried reaction may exacerbate an already difficult project by doing harm in the response to the disaster of the moment.

Once upon a time in Philadelphia, a charity hospital was seeking to modernize and expand its facility. Fundraising and design work had proceeded for a number of years, however, there never seemed to be quite enough money in the building fund to begin the project.
