APWACurbs

The APWACurbs subassembly inserts links for a standard shape concrete kerb-and-channel with subbase. The kerb and channel dimensions are based on the APWA Standard Plans for Public Works Construction, 2012 edition.

You should verify that the dimensions used match your interpretation of the standard plan.

Attachment

The attachment point is at the flange point of the channel, the back of the kerb or the face of the kerb.

Input Parameters

Note: All dimensions are in metres 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.

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.

None.

Runtime Logical Assignments

None.

Output Parameters

None.

Behavior

The kerb and channel links are inserted based on the values stored within the subassembly. All dimensions are positive, non-zero values. If a non-zero subbase depth is given, the subbase layer is not inserted. The subbase layer closes to the bottom-back-of-kerb.

The subassembly builds the shape for the selected kerb, kerb and channel, or surface kerb, with the attachment point either at (a) inside edge of the channel (or lip), or (b) the back of the kerb or (c) the flowline (or surface) of the kerb or channel.

Layout Mode Operation

In layout mode, this subassembly displays the kerb-and-channel component based on the input parameters given.
