View Trench Quantities

Once you have digitized all trenches of a job site, and then verified them in the graphical tabs, you can view the total quantities of the trenches in the Summary tab.

Before you begin viewing the data in the Summary tab, keep the following considerations in mind:
  • Trenches do not total by defined areas in a job.
  • Trenches excavate through the proposed layer. Viewpoint Estimating assumes that the materials have been brought up or down to proposed grade prior to the trench excavation.
  • Backfill does not include bedding materials or pipe displacement.
  • When you balance a site, you are lowering the proposed terrain not the pipe invert.
When you first open the Summary tab in a job, the initial totals in the upper-section may display totals with zero values. Before the totals can be displayed, the trenches or trench totals must be set as active. This is done by selecting the check box in the Active column.
Note: You cannot set the trench totals and any individual trenches as active in the Summary tab at the same time. You can set either multiple, individual trenches as active or the totals as active. This is to avoid inadvertently doubling the values.

View Trench Subtotals

Anytime there are multiple trenches of the same type, Viewpoint Estimating automatically subtotals those trenches and displays them in the Summary tab in the lower-section. The type is based on the Trench Template value in the Trench tab. For example: if you have three trenches with a type of Vertical-Trench 12IN Pipe digitized, each one would display in the Summary tab individually and a new section, Vertical-Trench 12IN Pipe – Subtotal.
Note: This automatic view of trench subtotals is not the same as viewing subtotals based on setting multiple areas as active.

If you need to view subtotals of trenches with different types, you will need to set those trenches as active individually and view the subtotals in the upper-section of the Summary tab.

View Trench Details

Viewing the trench totals in the Summary tab without details toggled on will display the following values:
  • Total Excavation - All material removed from the trench.
  • Pipe Displacement - The volume of space the pipe fills within the trench.
  • Backfill - Excavation values which do not include the amount of native material required to fill the trench back to proposed elevations. This number does not include pipe displacement and bedding volume.
  • Pipe Type - Displays the length of specified pipes.
  • Total Trench Length - The total length of the trench.
You can display additional trench details by clicking Detail on the speedbar. The following additional fields are displayed:
  • Disturbed Area - The disturbed width multiplied by the length of the trench.
  • Perimeter - The perimeter of the trench.
  • Fill (Excavated from Trench) - The amount of fill excavated from the trench.
  • Substrata/Unclassified - Substrata materials specified in borings or unclassified if undefined.
  • Disturbed Width - The width of the trench plus space for excavation equipment.
  • Maximum Trench Width - The width of the trench at its widest point.
  • Trench Depths - Displays the length of trench at defined cut depths.
  • Total Trench Length - The total length of the trench.
To hide the additional detail, just click the Detail button again.
Note: You cannot set the trench totals and any individual trenches as active in the Summary tab at the same time. You can set either multiple, individual trenches as active or the totals as active. This is to avoid inadvertently doubling the values.

Use Swell and Yield Factors on Trenches

Swell and yield values can be applied to any substrata materials as well as bedding and import materials. These values can be predefined within the Boring Attributes screen and Volume Attributes screen or entered within the Summary tab itself. See Enter Swell and Yield Factors for more information.
