Special-Purpose Simulation Model for Balanced Cantilever Bridges

Abstract

Construction of bridges’ decks involves different types of resources that interact in a cyclic manner. Further, the construction operation inherits uncertainties and a variety of demands. Contractors have to select the construction method that suits project constraints including: project conditions, technical, financial, and time constraints. There are several construction methods that can be used to construct bridges’ decks. This paper presents a special-purpose simulation model that aids government agencies and/or their representative in planning the construction of bridges’ decks using cast-in-place and precast balanced cantilever techniques. The pouring of concrete in cast-in-place balanced cantilever techniques can be executed either by using pump station and pump line, or truck mixers, whereas, the precast balanced cantilever technique is carried out using two methods: (1) placement by an independent lifting apparatus; and (2) placement with the help of a beam and winch carried by the bridge deck it...
