I'm looking for clarification on the reporting for the Corridor Mass Haul Roads. The customer is looking to determine the total distance material is being hauled.  This project is a fill project requiring the material to be imported from a borrow site. So they setup a Corridor, Create the Haul Range for a Side Dump, Along with a Borrow site and Haul road. In this example the distance of the haul road is 1407ft... However after running the corridor report the average haul distance is 382ft. Which is only reporting the haul distance within the corridor and not calculating the distance of the haul road. Maybe TBC cannot do what they are looking for, so looking for some clarification...

In Mass Haul there are two elements of a Haul -

1. The On Alignment Haul
   1. where you move Cut to Fill along the Alignment or
   2. Where you move Cut to Exit Point (To Take Material to a waste site) or
   3. Where you move import material from a Borrow site from its alignment entry point to a fill location
2. The Haul to Waste or Haul From Borrow using Haul Roads from the Waste / Borrow Site to the Entry / Exit Point on the alignment (Non Alignment Hauls).

So in your case because you have a Borrow Site and you are hauling along haul roads to the site and then you are hauling the Borrow Material from the entry point(s) to the Fill Location(s) you will find two elements that need to be computed to give you the Hauls.

There is of course not one single value for the Alignment Haul as the material will be dropped off at a variety of locations to cover the fill scenario of the Mass Haul - so we compute an Average Distance which is the distance from where the Mass Haul Material arrives on site from the Borrow Pit to the centroid of the Fill Mass Required

The video below shows where to find the materials and Haul Distances / Quantities in the UI and the Reports

The current implementation will give you all of the On Alignment Haul information for Cut to Fill or From Borrow (where it meets the alignment) to its Fill destination. To determine the Off Road Haulage Distances you will extract those from the TBC User Interface which reports those as properties of the Borrow Pits shown in the Mass Haul Diagram. For each Haul Path to the alignment we compute a total qty and the distance and cost of moving the material from Borrow Site to Alignment. Because one Haul Path can serve multiple On Site Hauls we split the data into the two parts - Bringing Dirt to Site and then distributing it on site.

The video explains all of the above with context of a dummy job.

Hope this helps Travis
