Financing construction projects is a crucial challenge for contractors in order to run sustainedbusiness. Being a concern of the whole corporate rather than the individual projects, contractors managefinancing at the corporate level. Contractors finance projects mainly through the owners' progresspayments supplemented by fund procured through establishing credit-line accounts. Given the facts thatowners actually pay after the accomplishment of the work while retaining some money, and the cash thatcontractors can withdraw from credit lines is limited in amount, contractors often operate under cashconstrainedconditions. Thus, the premise that the best proactive approach of financial planningcontractors can follow is to schedule construction activities based on the available finance is stronglyadvocated. The finance-based scheduling makes the expenditures of the activities during a given periodin balance with the available cash during the same period. A Strength Pareto Evolutionary Algorithm(SPEA) is proposed and employed to device a set of optimum finance-based schedules of multipleprojects being implemented simultaneously.
