Summary
Contractors See Cost Savings of Using Grade Control Technology …What are the greatest benefits of machine control technology ?
Source: Site Prep Machine Control study 2008
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 MentionsFuel savingsPractice surveying without a licenseProductivity
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
Why Finish Faster with Fewer Machines?
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
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
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
Grade Control Systems Two types of Grade Control Systems
1. 2D Conventional Grade Control Systems Laser Referenced systems Sonic Referenced systems
2. 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
Conventional Grade Control Systems and Applications
EXCAVATION
GCS900 2D FOR EXCAVATORS
Ideal economical and easy-to-use system to improve excavation productivity
Designed for excavation, trenching, grading and profile work
GRADING
GCS900 2D FOR DOZERS
Ideal for smaller construction sites, excellent first investment in grade control
Elevation, or elevation and blade slope control
FINE GRADING
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
QuickTime™ and a decompressor
are needed to see this picture.
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
Conventional Grade Control for Dozers and Graders
Traditional methods … vs. Conventional Grade Control
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

How Does 3D Grade Control Work?
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
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

disassembly
Almost eliminates install downtime
Standardization across a mixed fleet
Enhances machine value – Both now and at trade-in time
Most major Manufacturers Offer Trimble Ready Machines Today:
Caterpillar:– Dozers– Graders– Excavators– Soil Compactors– Scrapers
John Deere:– Dozers– Graders
Volvo: – Graders– Soil Compactors
Liebherr:– Dozers
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
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
2D versus 3D Grade Control Systems
Selection of 3D Grade Control Systems typically driven by:
– Cost saving factors Minimisation of project over run risk Reduction of up to 90% of the stakes Higher machinery utilisation Less rework
– Optimized data management and workflow CAD file usage as state of the art Closed workflow from design to realisation
and grade checking
