Brief History
Began with the purchase of LLNL’s first Audio Frequency instrument in the early 1990. Proactive step taken by LLNL as a result of an increasing number of utility
strikes Locates were performed out of the Craft Shop of Plant Engineering External building Locates
Between 1990 and 1998 Permit Process Documents Internal & External building Locates 30” No Dig rule Ferromagnetic scanners & Ground Penetrating Radar (GPR)
Between 1999 and 2000 Established Permit Database – issuing paper permits LLNL “One Call” center concept
Mindset / Purpose Preventing unplanned outages Reducing unplanned project costs Safety

Where we are at today
Permit Office has grown Size and responsibility Improved database tracking methods Two types of permits
• Soil Excavation and Concrete Penetration
Mindset / Purpose Preventing unplanned outages and reducing unplanned project costs Safety Culture shift
Today the permit office issues an average of 60 permits per month
Education/Training 3rd party certification required Safety Video
Incorporating new technologies Radio/Audio, GPR, and ferro-magnetic scanning Marker Ball program (open trench)
• Integrating with the Facility Information Center

The Permit Process
Responsible Individuals LLNL employees who serve as the point of contact Partnering with the Permit Office to ensure compliance Annual training requirement
Permit Office Locators
• Perform the locates and add any comments they may have on the permit – resources include As-builts / construction drawings / Utility drawings, etc…
Issue the permit upon receiving all approvals• Regulatory approvals • Utility Owner approvals• Signature Approvals
Job site field visits• Compliance Inspections
Permit Closure• Archived into the Permit database
