Abstract

Evaluating to what extent industrialized production methods used during the steel reinforcement, formwork and concrete casting of small bridges are beneficial to the construction industry. The study evaluates the economical value of the construction of small bridges in terms of design and constructability from a production point of view. Moreover, the health and safety issues of the production processes are considered. The study method used is the internal documents study involved in the construction of the bridges. A comparison between data collected for previous studies on bridge construction projects and data collected from internal company documents will be performed. The study uses an economic analysis to evaluate alternative construction materials, assemblies, and bridge services with the objective to improve project planners or owners‘ decision making during the course of planning, designing and constructing a bridge. The use of bridge economic analysis to determine the most economically efficient choice among bridge design alternatives when it comes to steel reinforcement, formwork and concrete casting in regard to improved quality and working environment. The study discusses and offers recommendations for a cost effective bridge construction process which reduces waste in the production process and keeps the project schedule.
