Construction Cost Report Variance Agent

A project cost report must show the budget, commitments, actual costs, pending changes and forecast final cost, and errors hide in unmatched invoices. At month-end cutoff, this agent pulls the budget, subcontracts, purchase orders, invoices and change log and builds the report by cost code. It checks that every invoice ties to a commitment and every pending change appears in the forecast. Unmatched items go back to the team to fix before it pulls again. It then compares forecast with budget and flags lines over 5% of their budget. Pending changes are forecast at the most likely value, and contingency use is shown separately. It drafts variance notes from the change log. The quantity surveyor or project manager writes the commentary and approves. Edge case: a change still under negotiation shows its range next to the most likely value.
