Background
Advanced route planning tool: Quantm
Conventional planning vs Quantm
Case studies
Conclusions
Between vision and viability there are important decisions to make
Around 80% of civil infrastructure projects are delivered over
budget, over time…
The greatest opportunities to contain overall costs and minimise
environmental and social impact are at the planning stage
Conventional planning methods heavily rely on professional
experience and judgment using manual methods
An intelligent route planning tool has been specifically developed
to address the complex planning process

Trimble Quantm Technology
Quantm is a revolutionary planning tool for road/rail alignment
selection with combined international expertise
– Scoping study
– Feasibility study
– Value engineering
It automatically generates multiple cost effective and viable
alignments that meet the defined constraints
• Consider all feasible alternatives to help make the best
decisions
• Dramatically reduce planning time and project costs
Quantm technology has been used globally for planning over
40,000km of road and railway projects
• Australia, New Zealand, America, Europe, Russia, Middle East,
Africa, South East Asia, China
Trimble Quantm Technology
…new technologies are transforming the way the world works
Trimble Quantm Technology Digital Terrain Model (DTM) based optimisation engine
Input data: End points, design parameters, cost data, constraints
Comprehensive corridor/alignment search within the study area
Simultaneous 3D optimization with multiple alternatives

Digital Terrain Model
200+ millions points
Planning method
Planning time
Manual, 2D
Months, years
Intelligent, 3D interactive
Weeks, productivity up 50%
Construction cost Often over budget Cost control
saving 5~30%
Alignment quality Heavily rely on
experienced engineers
Better fit into terrain
Balanced earthworks
Major structures/
Control points
Potential misjudgment,
missing viable corridors
Never miss viable
corridors/alignments
3D Visualization Limited in length or rely
on third party software Real time rendering
Sensitivity analyses
‘What if’ scenarios
Time consuming
Slow, labor intensive
Fast
quick response

Conclusions
Trimble Quantm assists planners to plan a new
road/rail project more rapidly with lower
construction costs. Quantm makes it easier to:
Consider all feasible alternatives to
help make the best decisions
Plan for sustainability with better
environmental and public outcomes
Invest in a better future by reducing
capital and operating costs
