A construction company is negotiating on a construction project with three- month duration. On the last day of each month the construction company may bill the owner for the work completed during the month. The owner pays the monthly bills one month after they are received. Final payment is expected one month after completion of the project and will include the 10% retention. The construction company pays material suppliers in full when they receive payment from the owner. The construction company pays subcontractors when they receive payment from the owner, but withholds 10% retention from the subcontractors payment. The construction company pays for labor during the month the labor is performed. The projected monthly material, labor, and subcontractor costs, as well as the amount the construction company will bill the projects owner each month, are shown below. Determine the total cash generated by the project at the end of each month and just before each payment is received from the projects owner. What is the maximum amount of cash invested by the company during the completion of the project?
