Enhancement Title

Flexible Duct Bank Conduit Numbering Decoupled from Concrete Geometry

Product / Platform

Bentley electrical / duct bank modeling tools (e.g., BRCM / Raceway & Cable Management)

Problem Statement

Currently, duct bank conduit numbering is locked to model position (row/column such as A1, B1, etc.) and tied to concrete geometry. When a conduit row or column must be added or modified after initial modeling, the entire duct bank must be deleted and remodeled to accommodate the new configuration. This results in unnecessary rework, loss of design efficiency, and limited flexibility during design iteration.

Proposed Enhancement

Decouple conduit numbering from concrete geometry and fixed model position by using run-based conduit IDs:

• Allow users to define a duct bank run ID at creation.

• Automatically number conduits within the run (e.g., 007DB001-A1, A2, etc.).

• Enable manual renumbering of an entire connected conduit run via properties editing.

• Concrete placement should reference existing conduit run IDs but should not control conduit numbering.

Proposed Workflow

1. User defines a duct bank run ID when modeling conduits; conduits auto-number sequentially within the run.

2. Concrete is placed around selected conduits based on user-defined clearances and adopts the run ID for identification only.

3. If design changes are required, concrete can be removed, conduits added or modified, and the run renumbered without needing to remodel the entire duct bank.

4. Concrete can then be re-applied without affecting conduit numbering.

Benefits / Business Value

• Significantly reduces rework when duct bank layouts change

• Enables easy addition or deletion of conduits late in design

• Improves reuse of existing conduit runs

• Removes design constraints caused by position‑locked numbering

• Provides a more intuitive, design‑friendly workflow aligned with real‑world iteration

Impact of Not Doing This

Design teams are forced to fully remodel duct banks for minor layout changes, increasing modeling time, frustration, and the risk of errors during redesign.

Requested Outcome

A more flexible and scalable duct bank modeling workflow that supports iterative design without requiring full remodels.
