! Records Review! Fieldwork

Multiple tools maximize detection capabilities

Non-intrusive & rapid investigation! Data analysis

Compile information from all datasets

Produce preliminary utility map

!

Targeted Test Hole Program

Calibrate depths

Identify Unknowns

! Final Mapping Results for 3D Modeling,Design, Construction & MCG

(1) DEFINITION OF ADVANCED MODELING TECHNOLOGY.In this subsection,the term advanced modeling technology means an available or developingtechnology, including 3- dimensional digital modeling, that can

(A) accelerate and improve the environmental review process; (B) increase effective public participation;

(C) enhance the detail and accuracy of project designs;

(D) increase safety;

(E) accelerate construction, and reduce construction costs; or

(F) otherwise expedite project delivery

! Utility and site modelsexported as IFC formatfrom AutoCAD/Microstation

!

IFC imports into BusinessCenter - HCE

! Bentley iModel format

imports coming soon

!

Business Center HCEcurrently only visualizes3D model as BIM objects

! No MCG model Exports

! Bentley and AutoDesk havemobile viewer apps

! Bentley Navigator app allows forGPS & metadata, but no camera

! AutoCAD app has camera &

GPS, but no metadata

! Positioning needs enhancement

! Plenty of room for improvementand more features

! Proprietary systems exist with

greater capabilities

! Determine geologic layerthickness

! Automate blade positionduring stripping/removal

!

Minimize amount ofwaste rock incorporation

! Maximize amount ofextraction

Mining Applications

!

Multiple tools & processes used to map utilitylocations

!

Underground utility positions + records = 3DModel

! 3D utility model data can be used in VirtualDesign & Construction

!

Mobile Apps bring touchscreen 3D to field

! Additional applications for bringingGeophysical Data into geologic Models exist
