Construction project budgeting after an estimate is approved
A project budget is the approved cost baseline for managing the job, not another standalone blueprint takeoff.
Structure the budget around actual work
Organize cost categories consistently enough to connect contracts, purchases, labor and expenses to the work being done.
Record approved revisions
Keep original budget and approved changes separate so project managers can explain movement over time.
Review forecasts, not just invoices
Actual expenses plus remaining cost to complete helps show potential overruns while decisions can still be made.
