Berm

The Berm subassembly inserts links to create a berm. The berm may be created from the inside toe or inside top of the berm. The berm then daylights to a surface.

Attachment

The attachment point is at the inside toe or inside top of the berm. This component can be attached to either the left or right side.

Input Parameters

Note: All dimensions are in meters or feet unless otherwise noted. All slopes are in run-over-rise form (for example, 4 : 1) unless indicated as a percent slope with a “%” sign.

Parameter	Description	Type	Default
Side	Specifies which side to place the subassembly.	Left / Right	Right
Attach Point	Attach point where the berm will be built from.	Inside Toe / Inside Top	Inside Toe
Berm Height	Height of berm measured from the attachment point.	Numeric	4 ft 1.2 m
Outside Side Slope	Berm slope on the outside of the berm.	Numeric	-2 ( : 1)
Inside Side Slope	Berm slope on the inside of the berm.	Numeric	3 ( : 1)
Top Grade	Grade of the top of the berm.	Numeric	2 (%)
Top Width	Top width of the berm.	Numeric, positive	5 ft 1.5 m

Target Parameters

This section lists the parameters in this subassembly that can be mapped to one or more target objects. For more information, see To Specify Corridor Targets.

Parameter	Description	Status
Berm Surface	Name of the daylighting surface. The following object types can be used as targets for specifying the surface: surfaces.	Optional

Runtime Logical Assignments

None.

Output Parameters

None.

Behavior

The initial inside link of the berm is created using the entered height and inside side slope. The top of the berm is created using the entered Top Width and Top Grade. A daylight link is found using the Outside Side Slope.

Layout Mode Operation

In layout mode, this subassembly draws the berm in fill with a link of 5 ft (1.5 m).
