Management should follow award, scope, design, procurement, production, dispatch, site work, acceptance, retention, claim, warranty and collection. Estimate-at-completion records preserve original scope and approved changes, revealing margin and cash still at risk.
Project controls and finance reconcile these records to accounts, advances and guarantees. The board sees whether variance arises from design, material, schedule, site or customer action. Reported revenue cannot hide unbilled work, claims or working-capital consumption.
Estimate-at-completion changes retain the underlying quantity, rate, design and customer assumption. Directors can challenge whether a margin recovery is supported by physical work and contractual rights instead of accepting an unexplained finance adjustment. The change trail supports customer negotiation, provisioning and disclosure without rewriting project history after the period closes.
