  1. Grade Control Systems and Applications

  2. Topics • Benefits of using Grade Control technologyfor earthmoving projects • Grade Control Systems and applications • Optimizing Grade Control Systems with the Connected Site solutions • Summary

  3. Benefits of Using Grade Control Technology for Earthmoving Projects

  4. Contractors See Cost Savings of Using Grade Control Technology … What are the greatest benefits of machine control technology ? Complete jobs faster and within budget Higher level of accuracy over conventional methods Fewer rework corrections Minimal to no staking Seeing data on the screen in the cab Gain a proprietary edge over the competition Check data ahead of time Perform daily as-builts Other Other Mentions Fuel savings Practice surveying without a license Productivity Source: Site Prep Machine Control study 2008

  5. Why Finish Faster with Fewer Machines? Lower your operating costs - Get to grade faster save machine hours, fuel - More accurate reduced material usage - Correct design in the field Eliminate rework - 3D implementation: Eliminate stakes, string-lines Less downtime - Operators know where to go - No waiting on sub contractors - No waiting on grade checking

  6. Trimble Customers Confirm… Savings • “We have proven […] over the past 5 years GPS Grade Control gives us a 28% to 33% increase in productivity.” • Tony Clark, Survey Manager and MC Technician, M. Hanna Construction • “We’ve been able to complete the project in less than half the time than if we had to stake everything the conventional way.” • C. Reytlinger, President, Norex Civil Contractors, BC • “We’ve literally cut our rework by 70% using the GPS system.” • Joey Keiffer, General Superintendent, Malphrus Construction

  7. Trimble Customers Confirm… Accuracy • “It gives me confidence that I‘m dead on in one pass” • Tony Pye, motor grader operator, Malphus • “I know and have absolute confidence that we’re providing a higher quality product to the Department of Transportation.” • Gerhart Pilcher

  8. In Summary … Grade Control Technology • Delivers significant benefits • Spikes productivity • Improves accuracy • Reduces rework • Improves profitability • These benefits are enhanced when combined with other Construction Technology • Site Positioning Systems • Construction Services • Connected Site

  9. Grade Control Systems and Applications

  10. Grade Control Systems • Two types of Grade Control Systems • 2D Conventional Grade Control Systems • Laser Referenced systems • Sonic Referenced systems • 3D Grade Control Systems • GPS/GLONASS systems • Optical Total Station systems • Support for a wide range of machines • Dozers, Graders, Excavators, Scrapers and Compactors • Installation on machines from any manufacturer • Many machines can be ordered Trimble Ready

  11. Conventional Grade Control Systems and Applications EXCAVATION GRADING FINE GRADING GCS900 2D FOR EXCAVATORS Ideal economical and easy-to-use system to improve excavation productivity Designed for excavation, trenching, grading and profile work GCS900 2D FOR DOZERS Ideal for smaller construction sites, excellent first investment in grade control Elevation, or elevation and blade slope control GCS900 2D FOR GRADERS Ideal for smaller roading projects or other jobs with tight tolerances and finished grading work Cross slope, or cross slope and elevation control

  12. How Does Conventional Grade Control Work? Laser beam or sonic tracer used as a reference for: - Flat / level elevation -Single plane or slope - Dual plane or slope

  13. Conventional Grade Control for Dozers and Graders Conventional Grade Control Traditional methods … vs.

  14. Slope & Depth Mode Profile Mode Depth Mode Laser Mode Conventional Grade Control for Excavators Angle sensors and an in-cab control box guide the user: - to a desired depth -to a slope and depth - along a profile -for measurements -to level the machine body - control and carry out desired depth and slope

  15. 3D Grade Control Systems and Configurations MASS EXCAVATION GRADING COMPACTION FINAL GRADE IDEAL GCS900 CONFIGURATIONS Dual GPS Excavator Single GPS Dozer Dual GPS Dozer Single GPS Scraper IDEAL GCS900 CONFIGURATIONS Dual GPS Dozer Dual GPS Grader Universal Total Station Dozer Universal Total Station Grader IDEAL CCS900 CONFIGURATIONS Dual GPS Compactor Single GPS Compactor IDEAL GCS900 CONFIGURATIONS Universal Total Station Grader Universal Total Station Dozer GPS laser augmentation Grader GPS laser augmentation Dozer

  16. How Does 3D Grade Control Work? The total station-based system measures the X-Y and Z coordinates Compares this to the preloaded design The design elevation and cross-slope for the current position are calculated and the blade is automatically moved to the correct cut or fill position The GPS/GLONASS receiver on the machine computes the exact position of the blade or bucket many times per second Compares this to the preloaded design The design elevation and cross-slope for the current position are calculated and the blade is automatically moved to the correct cut or fill position

  18. Trimble Ready • Machines ship “pre-plumbed” • All drilling, welding, painting, major disassembly • Almost eliminates install downtime • Standardization across a mixed fleet • Enhances machine value • Both now and at trade-in time

  20. 2D versus 3D Grade Control Systems • Selection of 2D Grade Control Systems typically driven by: • Ease of use and setup • Economical option to start out with • Flat or slope grading work • Lack of digital design data to use in the field

  21. 2D versus 3D Grade Control Systems • Selection of 3D Grade Control Systems typically driven by: • Project demands • Complexity of modern designs and getting them into the field • Increase of effectiveness • Expanding projects and company size • Machinery usage

  22. 2D versus 3D Grade Control Systems • Selectionof 3D Grade Control Systems typicallydrivenby: • Costsavingfactors • Minimisationofprojectoverrunrisk • Reductionofupto 90% ofthestakes • Higher machineryutilisation • Lessrework • Optimizeddatamanagementandworkflow • CAD fileusageasstateoftheart • Closedworkflowfrom design torealisationand grade checking

  23. Summary

  24. Get The Most Out of Your Grade Control Investment – What to Look For: • Get the best construction product available • Look for a manufacturer who specializes in Construction Technology • Look for a distributor who understands the construction business • Don’t forget quality: • Look for reliable, rugged solutions, built for sustained field and machine work: keep your crews and machines going • Don’t be left in the cold: • Look for a manufacturer who will be around • Look for a distributor with advice and service capabilities • Think ahead: solutions that grow with your business: • Look for scalable, portable product families • Look for a provider with a complete portfolio of field, machine control, asset tracking and office solutions

  25. Leverage the full suite of construction technology for the earthmoving to get the most out of your Grade Control investment Connected Site Solutions Asset Management Solutions Office Software Grade Control Systems Supervisor Systems Site Positioning Systems
