Workflow for Analyzing a Site Mass Haul

The goal of this workflow is to determine:

the most efficient distribution of in situ earthen material from cut zones to fill zones on a site.
the most efficient use of earthwork sites and haul roads to balance site earthworks.

Mass haul analyses help you estimate the earthwork costs of transforming your existing surface into a design surface.

Note: Your tasks may vary from these typical steps, so feel free to use commands in a different order or skip steps.


Steps		Help by Command	Notes
1.	If you want a more precise analysis using material properties (shrinkage, bulkage, and compaction factors), define in situ earthen materials and borrow materials in the Material and Site Improvement Manager.	Workflow: Manage Material/Site Improvements
2.	Work through the flow for creating and editing a surface or import an existing surface.	Workflow: Create and Edit a Surface	Two surfaces are required for a site mass haul analysis; the original surface and the design surface.
3.	Create a cut/fill map that indicates areas on a surface to cut and fill (based on a specified tolerance) to achieve a design.	Create Cut/Fill Map	A cut/fill map is not a surface; it is the difference between two surfaces. Red indicates material needs to be cut to reach the design surface and blue indicates fill material is required to reach the design surface.
4.	Create boundaries that cover the entire job site. One way to do this is to create a rectangular grid across the site that encompasses all of the cut and fill zones.	Create a Boundary Create a Linestring	Zones may be equal areas set out in a grid format or irregular shapes defining areas of cut and areas of fill. Multiple linestrings can be used to define a zone boundary providing they combine to form a closed area.
5.	Set Mass Haul Project Settings	Choose Project Settings	The Site Connection Tolerance determines if an earthworks site is connected to a haul road. The Haul Road Connection Tolerance determines if haul roads are connected.
6.	Run an initial analysis to determine the most efficient way to redistribute earthen material from cut zones to fill zones on a construction site.	Create Site Mass Haul Analysis	Set Auto-create path to Yes. Red flags indicate a zone is in excess or deficit.
7.	View the Mass haul balance view to see the movement of material between zones.	Mass Haul Balance View	Click on the column headings to sort by source or destination zones.
8.	Run a Site Mass Haul Report to see a textual representation of the results of the mass haul analysis, including an image from the Plan View, and the volumes and costs separated by source zones, destination zones, and haul roads.	Site Mass Haul Report
9.	Define the locations of borrow pits and waste sites within and around your job site.	Create Earthwork Sites
10.	Define a network of haul roads (routes for vehicles performing mass haul operations) by selecting existing lines and converting them to haul roads.	Convert to Haul Road
11.	Create additional haul roads as needed.	Create Haul Road
12.	Edit the Site Mass Haul Analysis	Edit a Site Mass Haul Analysis	Set Auto-create path to No.
13.	Refresh the mass haul analysis to account for the changes you have made since running the analysis.	Refresh a Mass Haul Analysis	Continue to add earthworks sites and haul roads until red flags disappear and the mass haul is balanced.
14.	Run the Site Mass Haul Report again to see the effect of your changes.	Site Mass Haul Report
15.	If needed, modify the network of haul roads to better manage the flow of the cut and fill volumes.	Edit You can also edit a haul roads attributes in the Properties pane.
16.	Refresh the analysis.	Refresh a Mass Haul Analysis
17.	View the balance properties between zones.	In the Plan View or Balance View, select a balance between two zones, and view the balance details on the balance page.
