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.; HCSS the estimating model is built for heavy civil unit-price work, so a commercial building contractor bidding lump sum gets a structure that does not match how it prices and will find the cost library concept awkward.
  • They diverge on capability: ALICE Technologies covers Generative scheduling, HCSS covers HeavyBid estimating.
  • 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 HCSS
  • 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 HCSS
  • 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 HCSS
  • A delay claim where the contractor must demonstrate to a client or adjudicator what the schedule would have looked like without a specific disruptionnot HCSS

HCSS

  • A highway or bridge contractor bidding unit prices against transport department item listsnot ALICE Technologies
  • An earthwork contractor that needs production quantities from the field to hit job cost the same day rather than at payrollnot ALICE Technologies
  • A utility contractor tracking owned equipment cost against jobs instead of absorbing it as overheadnot ALICE Technologies
  • A growing civil contractor that has outgrown estimating in spreadsheets and cannot reconcile bid to actual costnot 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.

HCSS

  • The estimating model is built for heavy civil unit-price work, so a commercial building contractor bidding lump sum gets a structure that does not match how it prices and will find the cost library concept awkward.
  • The products were built at different times and operate like separate applications sharing data, so estimating, field time and equipment do not present as one system to the user.
  • Pricing is quote-only and licensed by module and by user, so cost scales with field headcount even when a crew member only enters time once a day.
  • There is no accounting ledger, so payroll and job cost post into Viewpoint, Sage or a similar ERP, and maintaining that integration is an ongoing responsibility for the contractor.
  • Populating the estimating cost library needs an experienced estimator and a year or more of bids before the numbers are trustworthy, so a contractor without that person buys a bidding tool it cannot use properly.

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.

HCSS: Is HCSS a competitor to Procore?

Not really. Procore covers vertical and commercial construction project management. HCSS covers heavy civil estimating, field time and equipment, and the two are often used together.

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.

HCSS: Does HCSS include accounting?

No. It integrates with construction ERPs such as Viewpoint Vista and Sage rather than carrying its own general ledger.

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.

HCSS: Is pricing published?

No. HCSS quotes from a needs form and does not publish a rate card or per-user prices.

ALICE Technologies: How much does it cost?

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

HCSS: How long before HeavyBid pays back?

Usually after enough bids to build a trustworthy cost library, which most contractors measure in seasons rather than weeks.

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.
