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.; Navisworks sold in two named editions, Navisworks Simulate and Navisworks Manage, each licensed for install on up to 3 computers per subscription (Internet Archive capture, 7 January 2023)
  • They diverge on capability: ALICE Technologies covers Generative scheduling, Navisworks covers Clash detection.
  • 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 Navisworks
  • 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 Navisworks
  • 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 Navisworks
  • A delay claim where the contractor must demonstrate to a client or adjudicator what the schedule would have looked like without a specific disruptionnot Navisworks

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.

Navisworks

  • Sold in two named editions, Navisworks Simulate and Navisworks Manage, each licensed for install on up to 3 computers per subscription (Internet Archive capture, 7 January 2023)

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.

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.

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.

ALICE Technologies: How much does it cost?

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

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.
