Bridge Analysis Workflow

Cross-reference field POIs with documented bridge records for permit documentation.

The Bridge Analysis Workflow

When preparing permit documentation that involves bridges, RoadScope provides a structured workflow for cross-referencing your field measurements with the documented bridge inventory.

Step 1: Auto-Population

When you create a route, documented bridges are automatically added as POIs. Review the auto-populated bridges against your field survey — confirm that all physical bridges on the route are represented.

Step 2: Field Measurement Reconciliation

For each bridge POI, compare the documented clearance value against your field measurement:

  • **Match** — Your measurement confirms the documented value. Note this explicitly in the POI.
  • **Field lower** — Your measurement is more restrictive. Use your field value for load analysis — it is the current condition.
  • **Documented lower** — The documented value is more restrictive. Investigate — the bridge may have been raised, or the record may be outdated.

    • Step 3: Load Analysis

    With field measurements reconciled, run the load analysis against your load envelope. RoadScope flags any bridge where the clearance or weight rating may be insufficient for the proposed move.

    Step 4: Documentation

    The Full Report includes a bridge summary table with the inventory record number, field measurement, reconciliation status, and any notes. This is the format most permit offices require.

    Weight Rating Documentation

    For heavy loads that approach weight limits, document the Operating and Inventory ratings alongside any engineering letters or special permits obtained for the route.
