LIFE CYCLE PERFORMANCE OF BRIDGE COMPONENTS IN NEW YORK CITY

Bridge conditions in New York City are examined from an engineering management viewpoint. The objective is to optimize maintenance, repair and reconstruction expenditures over the structural life-cycle. Inspection records for the bridges and their components are reviewed. An attempt is made to develop relationships between the rate of bridge component deterioration in time and the maintenance operations. The most significant bridge components to emerge as targets of intensified maintenance are joints, bearings, wearing surface and paint. The article presents the current results of the continuing study conducted at the Bridge Management Unit of New York City Department of Transportation.
