CHAPTER

1 Introduction

•

Location GPS – Covers decimeter to submeter GPS positioning techniques including Satellite Based Augmentation Systems (SBAS) (such as WAAS, EGNOS, and MSAS), DGPS (reference station and rover operations), OmniSTAR VBS, XP, or HP services, and Location RTK (decimeter-level RTK positioning).

•

Total stations – The software can be used either with a total station using Servo, Autolock®, Robotic, or Reflectorless technology.

1

This SCS900 Site Controller Software Measurement User Guide provides you with the necessary information to perform measurement tasks with the Trimble® SCS900 Site Controller software.

To perform these measurement tasks, you need the SCS900 Site Controller software running on a controller that is connected to a Precision GPS or Location GPS system, or to a total station. This manual assumes that you have set up your SCS900 Site Controller System ready for measurement.

Even if you have used other Global Positioning System (GPS) products before, Trimble recommends that you spend some time reading this manual to learn about the special features of this product. If you are not familiar with GPS, visit the Trimble website (www.trimble.com) for an interactive look at Trimble and GPS.

SPS GPS receivers are all used in a similar way.

Each system simply offers a different range of configuration, performance, or setup characteristics, however, the basic concepts in using the receivers are the same. For specific operational capabilities or characteristics of each individual receiver, please refer to the user guide for that receiver, which provides full operational and maintenance information.

The SCS900 Site Controller Software operates on the following platforms, a tablet PC, a laptop, a Trimble TSC2® or TCU controller.

About the SCS900 Site Controller software The SCS900 software can be used with the following systems: •

Precision GPS – Covers centimeter GPS positioning techniques including Real-Time Kinematic (RTK) using a site base station (over radio), local base station (off-site over the Internet, cell phone, or rebroadcast radio), or a VRS™ network (VRS over the Internet, cell phone, or rebroadcast radio).

Note – The SCS900 software does not currently support moving base operations.

2 Measurements Menu In this chapter: Q

Measurement menu

The SCS900 software is a menu-driven system, for ease of use and learning. When you open the software, the main menu appears, providing access to six submenus:

Once set up, whether being used by GPS or by a total station, there are two main functions: 1. Measurements – This function enables you to measure and record the location, or as-built location, of features or surfaces or objects on a project, or to collect information that allows you to create a surface model, from which you can make volume computations, and grade or material thickness checks.

2. Stakeout – This function enables you to stake or relocate any aspect of the site including point features (such as manholes), line features (such as curbs, foundations, and footings), planar surface features (such as pads), or surfaces (such as site terrain models, side slopes and catch points, or road surface models). Refer to the SCS900 Site Controller Software Stakeout User Guide.

Measurements Menu

Measurement menu

The Measurement menu contains all site measurement functions. With the dedicated functions, you can check grades and material thickness, take topographic measurements to create surface models ( for example, volume computations), take site feature measurements to record the location of non-surface features, and provide real-time cut/fill information against a selected design model.

Before you enter this menu, set up the system using the System Setup menu. If you do not, when you select an option in this menu, the software automatically puts you through either the station establishment process ( for a total station) or the rover setup ( for GPS).

Command

Description

Check Surface Grade

Check the grade of a surface against a selected design.This option is available only when the current design is not a road.

Check Grade of Roadway

Surface Models

Surface models and SCS900 Surface models are very important to the way the SCS900 software works. They are used to compute volumes, check grade, and check material thickness.The SCS900 software enables you to either select design surfaces for staking out or checking, or to measure existing ground to create a new surface.

A surface can be made up of: •

an outer boundary

•

breaklines

•

surface points

•

volume boundaries

When measuring existing ground to create a new surface, it is crucial to know what the differences are between them.

Outer boundary The outer boundary defines the limits of a site. The surface is constrained to exist entirely within this boundary.

By using an outer boundary, errors in the field caused by working outside the site limits are eliminated.

Figure 4.1

Surface Models

Breaklines Breaklines help define the surface shape. They may be a hard feature (that is, the line defining the top of a man-made ditch) or a soft feature (that is, the line defining a change of gradient on a slope).

Figure 4.2

Breaklines

For information about features, see Chapter 9, Measuring Site Features.

C

CAUTION – Recording breaklines incorrectly or not recording them at all could have serious implications for the accuracy of the surface model.

Why measure breaklines?

Breaklines force the surface model to form correctly.

Figure 4.3

Diagram showing the effect breaklines have in forming a surface

SCS900 Site Controller Software Measurement User Guide

Surface Models

Are there any rules when measuring breakines?

You cannot measure a breakline that crosses another breakline, volume boundary, or outer boundary because at a crossing between two breaklines, the elevation at the crossing point is ambiguous.

Figure 4.4

When breaklines cross, the surface model cannot be formed because there is no way to know which of the above solutions are correct

Surface points A surface point defines the elevation at its location. These are used to fill in areas where there are no breaklines. The closer together surface points are recorded, the more accurate the surface model will be.

Figure 4.5

Volume boundaries A volume boundary defines the limits of an area where a volume quantity is required.

This could be the base of a stockpile or the top of an excavation.

Figure 4.6

Volume boundary

Volume boundary rules •

A volume boundary should lie on the reference surface (loaded design surface).

•

The SCS900 software will warn you if it is more than one foot off (0.3 m).

•

The volume boundary should be a line that is truly on the measured surface because it will act as a breakline in the resultant surface model.

•

The SCS900 software enables you to select a volume boundary between measured points. Avoid creating a volume boundary by clicking between, for example, four points at each corner, since this will create a bad model and large volume errors.

5 Creating a Work Order with Surfaces In this chapter: Q

Organizing data

Q

Creating a new work order and a new site

5

All SCS900 operations are carried out on a specific site. Work orders are associated with that same site. Before you can begin work, you need to create a work order or open an existing work order.

A work order contains a record of every measurement or stakeout operation completed.

Work orders also allow tasks to be monitored in terms of progress towards completion, and allow different types of tasks to have different settings and tolerances. Work orders also record every setting and change of setting made while you work.

Many tasks such as setting up a new site, design, or work order, and the settings or operational parameters for those operations can be established using the SCS900 software or the SCS900 support utilities ( for example, the SCS Data Manager, the Trimble Business Center software, or the Terramodel速 Field Data Module) and then transferred to the controller.

Establishing these tasks and settings in the office enables the supervisor to control and manage the quality of all the operations.

SCS900 Site Controller Software Measurement User Guide

25

5

Creating a Work Order with Surfaces

Organizing data Data is organized by site. Within each site, data is further divided into designs and work orders.

Sites An SCS900 site is a project that contains records of all activities that a crew does on a jobsite. The site contains the following: •

all settings and information that would be considered a requirement for the execution of any type of task (known as a work order)

•

a background map

•

a control points file

•

the GPS site calibration information

•

a geoid model for GPS operations

•

all software settings that would be considered applicable as the default settings for any task executed on the project

Site information is available to all work orders carried out on the site.

Storage of sites SCS900 sites are stored in the Trimble SCS900 Data folder or root folder.

•

•

•

If you are using a controller that runs Windows® CE .NET ( for example, the TCU), then the root folder is \Disk\Trimble SCS900 Data.

If you are using a controller that runs Windows Mobile® Pocket PC, ( for example, the TSC2), then the root folder is \<StorageCard>\Trimble SCS900 Data.

If you are running the SCS900 Tablet Edition on a laptop or tablet PC, then the root folder is \Trimble Synchronizer Data\PC\Trimble SCS900 Data.

In this way, if you synchronize other SCS900 controllers with the tablet PC using Trimble Office Synchronizer, they will be added as additional devices beneath the \Trimble Synchronizer Data folder so their information can easily be seen and reviewed using the SCS Data Manager.

Designs A site can contain one or more designs. Each design contains all the information relating to a specific aspect of the construction of the project, for example, original ground, finished grade, utilities such as sewers, electrical, gas, water, pads, roads, and other similar groupings. A single SCS900 design for example, can comprise a CAD drawing, one or two surfaces or roadway models, and a stakeout point list.

26

SCS900 Site Controller Software Measurement User Guide

Creating a Work Order with Surfaces

Information stored at this level includes foreground maps, stakeout data, and a design surface or road model.

Work orders A work order is a job or task (or a set of tasks) that needs to be carried out on a particular site. The following are typical tasks: •

checking grade on a completed surface

•

staking out a parking lot

•

measuring a stockpile volume

•

measuring a progress volume

The Trimble SCS900 Site Controller software is task-oriented. When you open a work order, the software automatically retrieves the data that you need to complete that work order.

A work order defines the site. It can also, but does not have to, reference: •

a design, which has the data needed to carry out the task

•

an underlying surface design, which has any previously-measured, saved surfaces that can be used for material thickness checking For a material thickness check, only an underlying surface design is required.

For a grade check and material thickness check, a design and an underlying surface design are required.

Two surfaces can be used to display cut/fill when using Location GPS with a poor vertical precision. The cut/fill values are the difference between a recent topo survey of the surface and the desired design surface.

A work order can also include basic written instructions to the operator that outline the requirements for the task.

Tasks such as setting up the base station, carrying out a station establishment with a total station, carrying out a measurement of the original ground levels for a site, and so forth, do not require the work order to have a referenced design.

Tasks such as carrying out a grade check of a finished surface, carrying out any stakeout operation, or displaying real-time cut and fill around the site require the work order to have a referenced design.

There can be many work order subfolders within the main work orders folder. Each work order subfolder contains: •

An initialization file called <Work Order Name>.ini that references the relevant design files and define the settings for the work order.

•

An Output folder that contains all data stored or output during the execution of the work order. This includes the data collected in the field, computed by the SCS900 software, or generated during field operations.

SCS900 Site Controller Software Measurement User Guide

27

5

Creating a Work Order with Surfaces

The following files are continually updated and stored in the Output folder: –

<Work Order Name>-Record.txt – Contains a record of every point measured or staked out, and includes station establishment and control point measurement records.

–

<Work Order Name>-Report.txt – Contains a record of every function used and every result reported on-screen during the execution of a work order. This is effectively a log file of activities and the results generated.

The following file is created when you complete a work order: – •

<Work Order Name>-Measure.dxf

An optional work order instruction file called <Work Order Name>.txt.

Global data The following data is used by all sites: •

Lists of feature codes

•

Lists of operator names

•

Geoid files

Creating a new work order and a new site Before you can set up the SCS900 software to use with a system and collect site measurements, you must create or open a work order. Every SCS900 field operation requires a work order, or task-related folder, into which field results are written.

You can create work orders in the following ways:

28

•

In the office – Using the SCS Data Manager or the Terramodel Field Data Module, you can assign it to a field crew and then use the Trimble Office Synchronizer utility to transfer the work order to a controller. For information about these utilities, refer to the SCS900 Site Controller Software Office Guide.

•

In the field – Directly on the controller by the crew in the field, as and when required, for example, to carry out a site measurement task.

The benefit of showing the difference between the two surfaces comes when using a low accuracy GPS device. For example, a site foreman might want to drive the site with a low accuracy GPS device to see where it is on grade, where it needs cutting, and where it needs filling. Location GPS will provide satisfactory horizontal accuracy, but not vertical accuracy. If the finished grade design is loaded as the primary design and the results of a previous day’s measurement (performed by a grade checker using Precision GPS) is loaded as the underlying surface design, the two designs can be compared as the site is driven around.

You may need to measure a feature when you want to record a feature, but do not want it to be part of the surface; you can then record it as a site feature.

A feature is a physical object or location of an event. A feature can be a point (a road sign), a line (a road), or an area (a parking lot). Points that can be recorded in a field to identify areas for special attention.

This information is not used by the software when a surface is created.

Glossary This section explains some of the terms used in this manual. benching

Benching is a process of aligning your GPS position (latitude, longitude, and height) to a benchmark that has been added as a reference point. The calibration offsets your GPS position to that of the benchmark, improving accuracy and providing a point that you can return to later.

chainage

A chain is a device like a tape measure. The term chainage is the running distance along a centerline or route that starts at 0.00 and increments as you proceed along the route.

Chainage is used in English colonized countries like New Zealand, Australia, and countries like Europe and Asia. It is not that well known in the USA where the same term is known as station or stationing.

elevation (elev, (1) Vertical distance (height) above or below mean sea level. (2) Vertical distance above or elv) below the geoid. (2) Distance above or below Local Datum. ellipsoid height

The distance, measured along the normal, between a point and the surface of the ellipsoid.

Not the same as elevation above a physical, vertical datum. GPS receivers output position-fix height in the WGS-84 coordinate system.

height

It can mean a target height or antenna height ( for example, 2 m of rod height).

See also ellipsoid height.

Here position

An autonomous instantaneous position derived from the GPS receiverâ&#x20AC;&#x2122;s uncorrected latitude, longitude, and height.

inclined plane

A plane surface that is at a slanted angle, set at an angle, other than a right angle, against a horizontal surface. An example of an inclined plane is a sloped surface such as a roadway to bridge a height difference.

Location GPS

Location GPS covers decimeter to submeter GPS positioning techniques including Satellite Based Augmentation Systems (SBAS) such as WAAS, EGNOS, and MSAS), DGPS (reference station and rover operations), OmniSTAR VBS/HP/XP services, and Location RTK (decimeter-level RTK positioning). In addition, it includes moving baseline operations to determine both position and heading of moving vessel providing the ability to rapidly position objects such as piling rigs, marine dredgers, or bridge sections in real time.

mains electricity or mains power

AC power.

Precision GPS

GPS positioning provided by techniques that typically deliver centimeter-level accuracy.

These include RTK (Real-Time Kinematic) techniques and signals obtained from a VRS (Virtual Reference Station) system.

site

A project that is to be worked on for a significant period of time. A site stores all design data and all executed work orders so you can easily find data whether you are in the office or in the field.

SCS900 Site Controller Software Measurement User Guide

1 07

Glossary

station

The station of a road project, is the position (distance) of the location in question along the centerline of the road. Station for a road does not necessarily start at zero, so the station of a location is not necessarily the distance from origin of the main alignment for the road.

The Station format can be xx+xx.x, xxxx.x, x+xxx.x, or x/xxx.x.

This term is used primarily in the US, whereas the equivalent term chainage is used throughout many other areas of the world.

work order

A work order covers a task to be performed by a crew on a single jobsite. A work order contains the reference to the appropriate design, required settings and tolerances for the task, and a record and report of all the data measured or staked out in the process of completing the task.

A work order can cover a short-term task (such as the stakeout of a specific building pad) or a task that will last the duration of the project (such as the stakeout of storm water drainage) and that will be executed periodically as required during the project.

When the project is complete, all the information regarding the task is stored in a single file that is easy to recall.
