Pros & Cons
O-Calc Pro
Pros
- Wind sweep across all 360 degrees finds the worst-case loading direction without the engineer having to set it by hand.
- Covers many loading codes, including NESC 2023, GO 95, CSA 2020, and AS/NZS 7000.
- Catalog-driven drag-and-drop 3D modeling speeds up building joint-use and make-ready models.
- Photogrammetry measurement tool takes attachment heights and wire sizes from photos.
- The 2024 database add-on adds pole data history and a network connectivity view.
Cons
- No public pricing; both the base software and the add-ons need a quote.
- Covers only pole structures, not general asset maintenance.
- Very few independent user reviews, so the vendor's accuracy and cost claims cannot be checked.
- The database and connectivity features cost extra on top of the base license.
Propeller
Pros
- Combines drone, LiDAR, GNSS rover and total station data on a single map, regardless of which hardware captured it.
- AeroPoints give survey-grade ground control without the manual surveying normally needed to set control points.
- Strong stockpile, cut and fill, and progress tooling, with a long track record in earthworks and aggregates.
- Integrates with common construction systems such as Procore, Trimble Connect, Autodesk Build and HCSS.
- The trust center shows a SOC 2 Type 2 attestation.
Cons
- No published software pricing, so buyers have to request a quote.
- Hardware such as AeroPoints and DirtMate adds separate costs on top of the software.
- Reviewers find less depth for vertical construction and interior fitout work.
- Some reviewers say the price may seem high to smaller clients.
