Pros & Cons
PPLS-CADD
Pros
- Bentley says it is used by more than 1,600 organizations in over 125 countries, and the acquisition announcement called it the US industry standard for transmission line design.
- Combines terrain modeling, sag-tension and thermal ratings (IEEE 738 and CIGRE 207) in one tool.
- Imports and classifies large LiDAR point clouds, and its AMBER tool builds line models from them automatically.
- Plan and profile drawings regenerate automatically when the design changes.
- Links directly to PLS-POLE, TOWER and the SAPS finite element engine for structural checks.
Cons
- No public pricing; buyers must request a quote.
- Bentley recommends about five days of training, so new users face a steep learning curve.
- Runs on Windows only.
- Covers design only: there are no work orders, maintenance or field inspection tools.
Trendspek
Pros
- Unlimited users on every plan, so contractors and stakeholders can be added without per-seat fees
- Overlays and compares photogrammetry, lidar, thermal and BIM data on one 3D asset record
- Strong security credentials, with ISO 27001, ISO 27701 and SOC 2 Type II, plus SSO, MFA and private cloud options
- Large named customers report results, such as NSW Ports cutting the cost of a jetty inspection by two-thirds
- The asset owner keeps the inspection history, whichever contractor did the capture
Cons
- No public prices, so a quote requires a consultation and pilot
- Processing of new captures is billed separately from the plan
- Not a full CMMS: work orders and spare parts depend on external integrations
- Few independent user reviews are available on the major review sites
