Cornerstone

Product

Turn changing project conditions into better-informed action.

Cornerstone is a decision layer for construction: it estimates the current condition of the work, compares practical responses, and presents expected outcomes with confidence and assumptions—for human review.

Understand current conditions

Combine available project and field evidence to estimate:

  • Production state.
  • Workface readiness.
  • Completion risk.
  • Constraint status.
  • Confidence in the available information.

Field information is often incomplete or delayed. The platform treats evidence as uncertain rather than assuming the record is perfect—and shows what is known, inferred, and still open.

  • Production vs. plan 62% Behind
  • Workface readiness 5 of 8 kits complete Uncertain
  • Milestone probability 54% (range 41–66%)

Update as evidence changes

Forecasts and action comparisons are revised when:

  • New progress information arrives.
  • Material status changes.
  • Crew performance differs from expectations.
  • Constraints are resolved.
  • An intervention is applied.

Compare practical actions

Evaluate the options teams actually have:

  • Add labor.
  • Change crew timing.
  • Expedite materials.
  • Reduce congestion.
  • Resequence work.
  • Release another work area.
  • Continue the current plan.

Show conditional results

The same action may produce different results depending on conditions such as:

  • Readiness.
  • Congestion.
  • Existing delay.
  • Crew experience.
  • Work complexity.
  • Predecessor completion.

Adding a crew to a ready workface is a different decision from adding a crew to a congested one. Cornerstone makes that difference explicit.

Learn across repeated work

The platform can use experience from comparable projects and work packages while adapting its estimates as current-project evidence accumulates.

Repeated floors, units, facilities, and trade packages mean the next estimate starts better informed than the last.

Explain recommendations

Each action comparison shows:

  • Expected outcome.
  • Probability of improvement.
  • Important conditions.
  • Alternative actions.
  • Confidence.
  • Key assumptions.
  • Relevant evidence.

Recommendations are designed to be reviewed and questioned—not followed blindly.
