Workflow for Analyzing a Corridor Mass Haul

Set up a network of haul roads with waste sites and borrow pits along a corridor construction site. Then run an analysis, review the mass haul diagram, and modify the mass haul calculations by adding barriers as well as material import and export locations. Recalculate to view the effects on the mass haul calculations. When you are satisfied that the earthwork is in balance, run the Corridor Mass Haul Report.


Steps		Help by Command	Notes
1.	Define materials.	Material and Site Improvement Manager Create and Edit Materials Create and Edit Earthen Materials	Define cut material and borrow material. If you are doing material processing, define a material process.
2.	Work through the flow for creating an alignment-based corridor.	Workflow: Create a Corridor
3.	Define the subsurface strata of earthen materials along the corridor.	Define and Edit Strata for a Corridor	In the Original ground list select the corridor's native surface. Select material surfaces if you are defining the strata by surfaces.
4.	Create boring logs and enter stratum thickness if you are defining the strata by boring logs.	Create and Edit a Corridor Boring Log	To enter boring logs by station and offset define the corridors alignment first.
5.	Run an initial analysis to determine the most efficient way to redistribute earthen material from cut zones to fill zones along a corridor construction job.	Create Corridor Mass Haul Analysis	In the Earthwork Sites group click Use default borrow/waste sites to automatically create borrow and waste sites at the start and end of the alignment and at barriers when they are required. Alternatively, click Use defined borrow/waste sites to see warnings at barriers and at the end of the alignment when there is an excess or deficit of material.
6.	Create a haul range to define the distance that each vehicle/machine can economically haul material.	Create Haul Range	Haul ranges are used when a mass haul analysis is balanced (see step 15).
7.	Define stations along an alignment beyond which earthen material cannot be moved.	Create Mass Haul Barrier
8.	Open a mass haul diagram of accumulated cut and fill volumes along a corridor's alignment to analyze the mass haul.	Corridor Mass Haul Diagram	You must select a corridor before opening the diagram. The view gives a complete picture of mass haul/earthworks with access to specific mass haul and volume/cost information and cost analysis.
9.	Create haul roads to represent routes for vehicles performing mass haul operations.	Create Haul Road
10.	Select additional lines and convert them to haul roads.	Convert to Haul Road	Define a network of haul roads by connecting earthwork sites to a corridor using the haul roads.
11.	Geographically define borrow sites, processing sites and waste sites. See also Understanding Material Processing Sites.	Create Earthworks Site	Use borrow sites to provide additional fill for an alignment when there is a deficit in usable mass earthen material. Use waste sites to offload accumulated usable and unusable material. Create material processing sites if you are converting materials to use as fill.
12.	If you are processing materials, assign processed materials to the corridor being analyzed in its corridor template.	Edit and Delete Corridor Template Instructions
13.	Recalculate the mass haul analysis and determine if there is a surplus or deficit of material at start/end points or barriers.	Refresh Mass Haul Analysis
14.	Force specified quantities of usable and unusable material to be accepted at one or more points along the alignment.	Create Mass Haul Import
15	Force the removal of specified quantities of material at one or more points along the alignment.	Create Mass Haul Export
16	Modify the network of haul roads to better manage the flow of the cut and fill volumes.		To change the shape of a haul road, right-click it and select Edit from the context menu. You can also edit its attributes in the Properties pane.
17.	Refresh the mass haul analysis.	Refresh Mass Haul Analysis
18.	Report on source and destination earthwork volumes for the mass haul analysis.	Corridor Mass Haul Report	The Source section shows volumes of cut at station intervals along the alignment. The volumes are broken down into cut, import (usable and unusable) and borrow (implicitly usable). The Destination section shows volumes of material used for fill at station intervals along the alignment. The volumes are broken down into fill (usable), export (implicitly usable) and waste (usable and unusable). Run the Excel version of the report to view the cut and fill broken down into specific materials.
19.	If desired, balance mass haul materials automatically or at specific grade points.	Auto-Balance Mass Haul Balance a Corridor Mass Haul at a Grade Point	Balance the materials in the mass haul analysis using the defined haul ranges.
20.	Run a report on the balance lines.	Balance Line Report	View the balance line report to see the movement of material from cut zones to fill zones.
21.	Add additional mass haul objects or edit existing ones.	Edit Mass Haul Objects	Introduce additional machinery, import/export sites, earthworks sites or haul roads to reduce overhaul, or modify your existing ones.
22.	Run a Material Processing Report (optional). Also see Workflow for Processing Materials.	Material Processing Report	If you set up a material processing site and material, run this to see values.
