Pit Excavation Boundary

To access this panel:

Activate the Home ribbon and select Boundaries | Pit Excavation
Run the command "survey-boundary-pit"
Activate any 3D window and use the quick-key combination "sbp"

You may wish to constrain your cut and fill volume reporting for EOM reports such as Pit Actual, Compliance to Plan or Compliance to Design to only include data within a limiting boundary. You do this in Studio Survey using pit excavation boundary strings. EOM cut and fill data can be limited using single or multiple closed strings.

As boundaries change over time, each boundary string object (containing one or more strings) is added to the database in relation to a reporting date.

You can use this panel in one of two ways (or a combination of the following):

Digitize string data using the Pit Excavation Boundary panel's New command and add it to the database with the specified date label.
Load previously-created boundary data and highlight a boundary (or boundaries), then add it to the database. Again, this will be added with the current Survey Date context.

String data that is associated with the same Survey Date will be available for selection when running an EOM report and that survey date is selected.

Example;

The image below shows a Previous and Current surface indicating excavation in the current reporting period. For the upcoming report, only the changes within a specific area are relevant:

The area outside the pit rim isn't relevant; only cut/fill results within the pit are desired. One way to constrain results is to digitize or import a boundary string around the pit rim in plan view.

To digitize a new boundary and assign it to the database, click New, digitize the boundary then ensure it is selected/highlighted. Finally, click Add Selected to add it to the current database using the specified Survey Date.
Alternatively, load existing boundary data, highlight it in a 3D window and click Add Selected.

For example:

You can quickly generate a pit excavation boundary at a fixed elevation using the Surfaces ribbon's Plane | Section command. This can be used to generate a string at the intersection of the pit shell with a default section direction, or the current section definition.

Field Details:

The following fields are available on the Pit Excavation Boundary panel:

Current Pit: the pit to which the boundary data belongs. Change this using the browse button.

Current Area: the area of the pit to which the pit excavation boundary belongs.

Surveyor: all surveyors that have been added to the database are available for selection using this drop-down list.

Survey date: select the date represented by the boundary data here. All string data added via the ROM Stockpile Boundary panel will be grouped into a date-specific collection that can be selected during subsequent reporting.

Pit Excavation Boundary: click New if you wish to digitize a boundary in a 3D window.

Add Selected: add the currently highlight string data to the database (associating it with the current Survey Date and assigning the specified Pit Excavation Boundary.
