What LPS does

Built for the people who make the plan, and the people who actually build it.

01 · Plan

Weekly commitments that actually finish.

The Last Planner® System, made routine. Draft the lookahead, negotiate the week, and roll forward what got done — PPC and reasons tracked automatically.

  • ▸ Weekly lookahead · commitment window
  • ▸ PPC trend + Reasons-for-Non-Completion
  • ▸ One activity, one owner, one week
02 · Unblock

Constraints resolved before they bite.

Every activity carries a nine-category constraint sheet — drawings, materials, permits, predecessors, labour. Notes, owners, ready dates, all in one place.

  • ▸ 9 constraint categories per activity
  • ▸ Formal constraint notes + attachments
  • ▸ Ready / Open / N/A per line
03 · Sync

Primavera P6 sync — without losing site data.

Re-import the XER any time. Delta preview shows what P6 changed; site commitments, constraint notes, and field photos stay exactly where they were.

  • ▸ Delta import preview + commit
  • ▸ Field vs Plan claim ledger (audit-safe)
  • ▸ Reason Queue for divergent progress
