Alternative bridge construction methodologies

Abstract

This report discusses two common methods of gaining access for bridge construction. These methods are working trestles and barging. Two working trestles designs and two barging methods are described. A cost analysis of these methods based on a specific bridge construction site in N.B. was discussed. The working trestles were determined to be the most economical alternative. A technical comparison of the working trestles and barging methods was discussed. Working trestles were determined to be the more effective alternative of bridge construction.
