Factors Governing the Design of Large Steel Bridge Projects

THE design of a bridge or any other engineering project implies the adjustment of certain means to certain ends, and both means and ends are considered in terms of money. Co-existing with the financial problems involved is economic design. Further, a bridge project implies not only the expenditure of money for the attainment of certain ends, but the meeting of all costs as they arise. The expenditure of a capital sum of money in first cost, and the meeting of capital charges and revenue costs out of income, is undoubtedly a financial problem, and the methods by which financial equilibrium is to be obtained must be established before the design is completed. Economic design implies financial equilibrium. In analysing a bridge project a wide interpretation must be given to the term "Finance" met in Economic Science. W. Nelson Elgood
