About the RPS Earthworks - TBC Documentation category

In this category you will find documentation relating to the use of Trimble Business Center with the RPS - Earthworks system.

TBC is used to create the following types of data for the RPS - Earthworks System

Work Orders

There are three primary types of Work Orders that can be created in the RPS - Earthworks System

  • Backfill Work Orders
  • Grading Work Orders
  • Bulk Earthworks Work Orders

In all cases the Work Orders require the following types of information

  • The Existing or Start Point Surface Model
  • The Design Surface Model
  • An Optional Capping Design Surface Model (Backfill Work Orders only)

In addition the Work Orders require a boundary that limits the area that will be analyzed using the Work Order concept which limits the computations of volumes and progress / productivity

Once created by TBC, the RPS - Earthworks system can be used to define the Work Order parameters that will define the schedule, the tolerances, the crews and expected production rates that will leverage the surface and boundary information delivered to RPS - Earthworks by TBC.

Surveyed Surfaces

A surveyed surface is a surface created by TBC that represents the current state surface of the mine based on a periodic survey (typically a drone flight but could also be a surface scan or a traditional total station or GPS topo survey). The surveyed surfaces that are uploaded to TBC will affect any Work Orders that are currently in progress where the surveyed surface covers any part of the area defined by a work order boundary. The surveyed surface is added into the production model at a specified date and time, and effectively updates the production model with the surface information at that point in the production timeframe. As soon as a machine passes over any point in the surveyed surface while executing a work order, after the specified date and time of the surveyed surface, the machine data will update the production model from that point forwards.

Images and Image Map Layers

When the project is surveyed, high resolution imagery is also captured. This imagery can be uploaded to the RPS - Earthworks system as high resolution imagery map layers. TBC provides the tools to transform the imagery e.g. into South Azimuth coordinate system and then capture the image as either a single image or as a series of tiles that can then be uploaded as a Map Layer to provide a backdrop to the Work Order results that are being generated by machine data and or surveyed surfaces.

Linework, CAD Objects and Map Layers

It is often a requirement to represent CAD linework representing project features such as Buildings, Conveyors, Utilities, Haul Roads, Working Areas, Stockyards etc. or design linework for ongoing work orders within the Map Layers of the RPS Earthworks System. TBC provides the ability to select CAD linework, Text, Polygons etc. and upload them to the RPS system in KML format as a set of map layers that can be overlaid on the aerial imagery tiles to highlight key features or project work areas etc.

TBC provides two main commands for connecting to the RPS Earthworks System

  • Earthworks Website command - provides a one click access to the RPS Earthworks system website.
  • Earthworks Work Orders command - provides a single command to manage Work Orders, Surveyed Surfaces, Imagery and Linework Map Layers.

In addition the RPS Earthworks system can utilize KML files containing linework, polygons and text generated by TBC using the Export to KML/KMZ command. The work to support the KML/KMZ linework export is ongoing currently and should be completed by April 15th 2021.

This area of the community provides documentation for those two Earthworks commands as well as support documentation that provides recommended workflows for creating and managing digital design information, survey information and for creating models suited for the GCS900 system and the Earthworks system.
