The John L. Tishman Distinguished Lecture is available to view live online for those who register here.

The lecture will take place on Tuesday, October 1 at 3:00 pm in room 2355 of the G.G. Brown building with a reception to follow. Please review the abstract and biography below.


This talk will provide an overview of some of the challenges faced while interpreting results from the application of traditional Critical Path Methodology (CPM).

The lecture will focus on three distinct concepts, i.e., resource-constrained scheduling, scheduling with multiple calendars, and single-duration activity estimates. These concepts are mainstream elements called for, explicitly or implicitly, in construction scheduling specifications. The lecture will show why the Critical Path (or lack thereof) cannot be trusted without performing additional checks and balances and it will also demonstrate and explain, albeit theoretically, why many construction projects overrun the baseline schedule.

The lecture will suggest mitigating strategies for each of the challenges and turn the lecture’s title around to: Three things I am glad I now know about traditional CPM. In many ways, the lecture will “burst the CPM bubble” however, it will do it proactively because ignorance will never be an excuse. Knowledge is power, indeed, but its usage comes with immense responsibility.
