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 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 and Applications

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

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
