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.


Jesus M. de la Garza is the holder of the Vecellio Professorship in Construction Engineering and Management at Virginia Tech. He leads the Center for Highway Asset Management ProgramS (CHAMPS), which conducts research and supports VDOT on the privatization of highway maintenance. Dr. de la Garza has been inducted into the National Academy of Construction and has received ASCE’s 2011 Peurifoy Construction Research Award; He has also received the Construction Industry Institute’s Richard L. Tucker Leadership & Service Award as well as their Distinguished Professor Award. Dr. de la Garza is the Editor-in-Chief for ASCE’s Journal of Construction Engineering and Management. He received his MS and PhD from the University of Illinois and his BSCE from Tecnologico de Monterrey, Mexico.

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
