  • Cost Evaluation

QES evaluated the reasons for differences between estimated costs based on past experience for a variety of GRS bridge projects. A detailed evaluation of costs vs. project estimate, and the reasons for differences was performed. QES developed alternative structure foundation types for the selected projects, and developed cost estimates for comparison with the GRS project; evaluated criteria which could be identified as cost drivers for unanticipated cost; and compiled a list of recommendations, including more extensive alternative evaluation, avoiding certain costly practices recognized for increasing costs.
