One City. One Problem.
Episode 03 | Subsurface risk
The project schedule is certain. The subsurface is not.
Records are incomplete and the schedule is fixed. How can the project team reduce subsurface uncertainty before it becomes a change order, delay, or safety incident?
The situation
A city is about to begin a high-impact corridor project. Available utility records are incomplete, differently formatted, and sometimes contradictory. Survey marks, legacy drawings, institutional knowledge, and field observations each tell part of the story.
A late discovery could create a safety incident, redesign, claim, or months of delay.
The decision
What level of subsurface confidence does the project need, where is uncertainty most dangerous, and how should the city close the gaps?
Three expert contributions
How can the city turn fragmented records into a usable starting hypothesis?
Show a practical method for collecting, normalizing, comparing, and scoring records. Make uncertainty visible rather than presenting an artificially clean map.
Which field methods should be used, where, and to what standard of confidence?
Show how non-invasive detection, survey control, targeted investigation, and professional judgment work together. Explain why method selection should follow project risk.
How should verified findings and remaining uncertainty change design, procurement, schedule, and contingency?
Show how subsurface intelligence becomes a managed project input rather than a standalone deliverable.
What the roundtable will test
Roundtable prompt
The project cannot investigate every linear foot. Where should the team spend its next dollar to reduce the most consequential uncertainty?
