The short version

  • Each has a real cost: ALICE Technologies the output is only as good as the recipes, and building accurate recipes is specialist modelling work most contractors cannot staff, so engagements depend on ALICE or a consultant doing it, which turns software into a services contract.; 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: ALICE Technologies covers Generative scheduling, Propeller Aero covers Photogrammetric processing.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

ALICE Technologies

  • A data centre programme where six months of earlier energisation is worth more than the entire construction management budget, and the owner wants evidence that a proposed sequence change actually delivers itnot Propeller Aero
  • A contractor facing liquidated damages that must decide between a second shift, a second crane and resequencing, and needs the cost and duration consequence of each before committingnot Propeller Aero
  • A bid team wanting to submit a shorter programme than competitors while proving to the client that the resource profile is achievable rather than optimisticnot Propeller Aero
  • A delay claim where the contractor must demonstrate to a client or adjudicator what the schedule would have looked like without a specific disruptionnot Propeller Aero

Propeller Aero

  • A quarry that reconciles stockpile inventory monthly for its accounts and wants the volume evidence to survive an auditnot ALICE Technologies
  • An earthworks contractor claiming progress payments on cubic metres moved who needs an independent measurement the client will acceptnot ALICE Technologies
  • A civil site checking whether a subgrade is within tolerance of the design before the surfacing crew arrivesnot ALICE Technologies
  • A mine that wants weekly volume reporting without a survey crew on the ground every weeknot ALICE Technologies

Where each one falls short

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

ALICE Technologies

  • The output is only as good as the recipes, and building accurate recipes is specialist modelling work most contractors cannot staff, so engagements depend on ALICE or a consultant doing it, which turns software into a services contract.
  • Pricing is quoted per project or programme with no published rates, so the tool is effectively unavailable to anyone who cannot justify a bespoke enterprise negotiation.
  • It only pays back on projects where float has a high monetary value; on a mid-size commercial building the modelling effort exceeds the schedule saving, which is why the customer list skews to data centres, energy and heavy civils.
  • A generated schedule still has to be accepted by superintendents and subcontractors who did not build it, and adoption failures are usually social rather than technical: the field runs the plan it believes in.
  • The 2026 McKinsey alliance pushes distribution towards consulting-led engagements, which raises the effective cost of entry and makes the direct-purchase path less certain for a contractor that just wants a licence.

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

Answered from the vendors’ own pages

ALICE Technologies: What does ALICE actually produce?

A set of alternative construction sequences generated from your constraints, scored on duration, cost and resource use, so you can choose rather than accept one plan.

Propeller Aero: How much does Propeller cost?

The platform is quoted and not published. AeroPoints are 1,000 US dollars each, with the corrections network included for twelve months and thereafter free while a platform licence is current, otherwise 1,000 dollars a year per group.

ALICE Technologies: Does it replace Primavera P6?

No. It imports from and exports to P6. P6 remains the contractual schedule of record on most projects.

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.

ALICE Technologies: Is the company still operating?

Yes. ALICE is active as of 2026 and announced an alliance with McKinsey in April 2026 to deliver AI scheduling to McKinsey clients.

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.

ALICE Technologies: How much does it cost?

Not published. It is quoted per project or programme and typically includes modelling and onboarding services.

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.

ALICE Technologies: What size project justifies it?

Projects where a week of schedule has a large monetary value: data centres, energy, industrial and major infrastructure. It is hard to justify on standard commercial building work.
