Question: For the project whose data are shown here, plot the cumulative project expenditures, value of work, and progress payments received versus time. What is the contractors maximum negative cash flow and when does it occur? Progress payments are calculated at the end of each month and received the middle of the following month. Retain age is 10% until project completion. Assume that final project payment, including released retain age, is received the middle of the month following project completion.
