THE ECONOMICS OF LOW COST BRIDGES

THE PRINCIPAL FACTORS WHICH DETERMINE ECONOMY OF BRIDGES ARE FIRST COST, INTEREST RATES, SERVICE LIFE AND MAINTENANCE. THESE FACTORS ARE ANALYZED AND APPLICATIONS ARE MADE TO METHODS FOR CALCULATING THE TOTAL CARRYING COST. EXPERIENCE IS CITED TO SHOW THAT CREOSOTED TIMBER IN BRIDGES MAY BE EXPECTED TO LAST UNTIL THE STRUCTURES ARE RETIRED FROM OBSOLESCENCE, WHICH SHOULD BE FROM 35 TO 40 YEARS. MAINTENANCE EXPENSE MAY BE EXPECTED TO COMMENCE AFTER APPROXIMATELY 15 YEARS OF SERVICE AND REACH A MAXIMUM IN ABOUT 35 YEARS. /AUTHOR/
