Use AI to Review Lookahead Schedule Changes.

In a hypothetical bathroom remodel, the new lookahead moves cabinet installation from Tuesday to Thursday. The countertop template visit still appears on Wednesday. A summary that says “cabinet installation moved two days” has captured the edit but left the project manager with the harder question: has anyone reconciled the template visit?

Use AI to prepare a change review between schedule versions. Ask it to show the old entry, the new entry, and the questions that need a person’s answer. Keep schedule approval and trade commitments with the project manager.

Name the versions before comparing them

Procore’s current lookahead documentation describes a comparison against the latest uploaded master schedule and flags dates that differ. That is a useful distinction: comparing a lookahead with the master answers a different question from comparing this week’s lookahead with the one your trades received last week.

Datum’s recommendation is to make the comparison explicit. Record the project, document names, revision dates, covered date ranges, and the version actually distributed. If the prior issued copy is missing, say so. Do not quietly substitute an older file and describe the result as changes since the last update.

Match the work before matching the dates

Use activity IDs where they exist. When they do not, compare the task name, room, trade, and surrounding activities. Two rows labeled “trim” may describe different work. A renamed activity may describe the same work. Mark uncertain matches for review rather than merging them into a confident narrative.

A rolling lookahead also changes its date window. An activity absent from the newer file may have fallen outside that window. Its absence does not establish that it was canceled or completed. Keep “outside the compared window,” “removed from the supplied file,” and “recorded as complete” separate.

Make each change easy to check

For the hypothetical cabinet move, the review should preserve both dates and link to both source rows. The Wednesday template appointment belongs beside it as a question for the PM. Unless the records confirm a dependency, describe the possible conflict as something to check. Do not invent a new template date or report that the fabricator agreed to move.

• Source comparison: the exact earlier and later records, including their issue dates.
• Observed change: task, location, old value, new value, and any uncertain match.
• Follow-up question: what needs confirmation and which recorded contact or responsible role can answer it.
• Review decision: the PM’s disposition, with any approved schedule change recorded in the team’s scheduling system.

Keep explanations separate from observations. A date shift does not prove why the work moved. A supplier email might explain a material issue, but it does not establish the full schedule impact. Leave missing reasons visible so the reviewer can ask the right person.

Test the comparison against a known answer

Anthropic’s evaluation guidance distinguishes what an agent says it accomplished from the actual result and recommends repeated trials because outputs can vary. Applied here, a fluent change summary is insufficient evidence that the comparison worked. These are established evaluation principles, not a new construction scheduling capability announcement.

For a proposed trial, have a PM mark the expected changes in a pair of past schedules before seeing the AI draft. Include a renamed task, duplicate task names, a date-window change, a missing earlier version, and a moved activity with an unresolved appointment nearby. Repeat the comparison to see whether the output stays consistent.

Record missed changes, false changes, unsupported explanations, and the time spent checking and correcting the draft. Compare that total effort with the current review process. No time savings are assumed. Start with a read-only review, and release revised dates through the team’s existing approval and communication process.
