Trimble  Quantm  Haul Road Optimization Presenters Name

Overview  The haul road problem – what are we trying to solve  The Quantm Software  Integrated workflows using the Trimble Tablet

Haul roads  The main consideration is optimal grade –Reduce fuel consumption –Reduce tire wear –Reduce machine wear  Two main consideration for haul roads –Maintenance, performing analysis on existing haul roads to maintain or improve haul road grade –Site expansion, preforming analysis to create and select new haul roads

Trimble Quantm Alignment Planning System  A unique system route alignment optimization  Applied by mine and site planners  Investigates millions of alignments for: –Faster Project Planning –Reduced Capital Construction and Operating Cost –Better Environmental and Public Outcomes –Thorough Demonstration of Alternatives Analysis

 Enables the simultaneous consideration of multiple factors during the alternatives analysis phase: –Environmental –Engineering –Economic/Cost –Community Trimble Quantm Alignment Planning System

Trimble Quantm Desktop Applications  Planning of haul roads for mining and construction  Traditional alignment planning  Estimation and initial management of project earthworks and mass haul  Design construct value engineering  Alternative analysis during construction

Trimble  Quantm  Desktop  Key feature – Vertical Optimization –Import CAD road design (horizontal only or 3D)  If 3D, quantity and construction cost of the alignment is calculated –Manual creation and editing horizontal alignment –Vertical optimization of existing design if 3D alignment imported –Vertical optimization and creation of vertical design for 2D or manual 2D alignment –Study are size, 10km x 10km or 20km x 20km licenses  Why buy Desktop? –Entry level solution – scalable to Premium and Service products –Manual creation of geometric alignments with quantities and costs –Vertical-only optimization, horizontal held fixed –Assists earthworks and costs by manipulating vertical of existing alignment

Trimble Quantm Desktop Premium  Key features – Full Optimization –Full horizontal and vertical optimization capabilities in addition to Desktop version  Unseeded - Free to roam optimizations  Seeded - Optimize from initial alignment both horizontally and vertically  Realignment - optimize based on minimizing deviation from existing centreline –10 x 10, or 20 x 20 km licenses  Why buy Desktop Premium? –Proven capabilities of the Quantm service on the users PC –Optimize existing concept designs vertically –Conduct full scoping, feasibility and final alignment studies, from defining corridors to detailed 3D alignments

In field Haul road workflow 1.Use SCS900 to collect existing Topo information and features. 2.Transfer TTM surface and feature data from SCS900 to Quantm Desktop (on Tablet)  Maintenance applications collect existing centreline of haul road for vertical optimization, in addition to site features.  New haul roads collect any features (streams, water features etc) 3.Switch to Quantm Desktop and perform optimization 4.Transfer resulting haul alignments back to SCS900 for stakeout

Haul Road Stakeout  Detailed ground survey –Additional updates to the model  Staking out the corridor –Export alignment as PRO file –Stake out earthworks footprint with GPS or Total Station

Construction  Haul road construction –Export alignment via TBC/TCC to a machine for construction of haul roads
