How is construction cash flow projected and managed?

Cash flow projection: (1) Develop cost-loaded schedule allocating budget to activities, (2) Apply S-curve distribution for monthly spending, (3) Model revenue - progress payments with retainage (typically 10%), (4) Account for timing - expenditure before payment, pay application processing time (30-60 days), (5) Include financing costs if negative cash flow. Cash flow curve shows monthly expenditure, cumulative cost, and payment timing. Front-loading (billing early) and mobilization payments improve contractor cash position. Monitoring actual vs projected identifies problems early.
