The short version

  • Only BuildingConnected has a free tier, so it costs nothing to try first.
  • Each has a real cost: BuildingConnected no pricing details disclosed on product page; contact sales required; Propeller Aero platform pricing is not published and is scoped by sites and users, so a contractor with many short-lived sites can be quoted very differently from one with a few long ones, and neither can benchmark against a list price
  • They diverge on capability: BuildingConnected covers Bid management, Propeller Aero covers Photogrammetric processing.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

BuildingConnected

  • No pricing details disclosed on product page; contact sales required

Propeller Aero

  • Platform pricing is not published and is scoped by sites and users, so a contractor with many short-lived sites can be quoted very differently from one with a few long ones, and neither can benchmark against a list price
  • The corrections network is free only while you hold a current platform licence, so cancelling the platform subscription reintroduces a 1,000 dollar per year per group hardware cost that many buyers do not model
  • AeroPoints are a hardware purchase at 1,000 dollars each and most sites need several, so the true entry cost includes several thousand dollars of equipment on top of a subscription
  • It measures rather than designs, so a contractor still needs Civil 3D, Trimble Business Center or an equivalent to produce and revise the design surfaces the measurement is compared against
  • Accuracy depends on flight planning, ground control placement and weather, and a poorly flown survey produces a confident wrong volume, so an organisation still needs someone who understands survey error rather than only a drone pilot

Propeller Aero: Do I need AeroPoints?

No, you can use conventional surveyed ground control, but the AeroPoints workflow is the main reason contractors choose Propeller over generic photogrammetry.

Propeller Aero: Is it survey grade?

Propeller states centimetre-level accuracy with correct ground control. Whether that satisfies a contract depends on your specification and on how the survey was flown, not on the software alone.

Propeller Aero: Who owns the data?

You retain your survey data and can export surfaces and point clouds, but check the export formats and retention terms in your contract before closeout, because bulk historical export is not a self-service one-click operation.
