Corridor

Corridor

Allows you to edit the name of the corridor.

This shows the HAL and VAL along which the corridor has been created. Frequently, the HAL serves as the centerline of the corridor.

This shows the surface (if any) representing the site's existing topography that is referenced by the corridor template's instructions.

These show the earthen (mass earthworks) materials from which the corridor will be built. Earthen materials can account for shrinkage, bulkage, and compaction factors, making your volume calculations more accurate.

• Native material - Select the uppermost/most representative earthen material of the original ground surface or native material that exists on-site.

Note: If no subsurface earthen material strata have been defined, the Native material control will be enabled, allowing a single representative earthen material to be identified. Otherwise, the materials associated with the defined strata will be employed as they are encountered via excavation, and the Native material control will be disabled.
Note: In corridor mass haul operations, the native material is always used as the cut material, even if a strata has been defined (see Understanding Materials in Corridor Mass Haul).

• Borrow material - Select a material to be obtained from off-site sources should there be a net deficit in material/a non-native material that must be brought from off site.

These settings are important when you perform corridor takeoff calculations, analyze mass haul needs for the corridor, and when you run a Corridor Earthwork Report.

Method used for corridor earthwork calculations.

This shows the maximum distance allowed between an arc and its chord (or a diagonal triangle edge) when the triangles are flat versus twisted. When this tolerance is exceeded, additional triangles are created to further densify the surface.

See Taking Control of your Surface Creation - Breakline Tolerance in the Trimble Community for details.
