"Out on this job recently and here is one that should be a teaching moment because when he arrived about 95% of the saw cutting had been complete. With the slab exposed, there were dozens of conduits that were not marked because the contractor wasn't concerned about hitting them. The power to all the panels was disabled and demoed so the only panel that still had live electricity was the room that was scanned. A situation that luckily nobody was hurt but could have been. Call us first before starting a project."
