| Abstract | This cost study was initiated to compare EEs (engineer’s estimates) to winning bids for 13 GRS-IBS (Geosynthetic Reinforced Soil–Integrated Bridge System) projects and evaluate ICEs (independent cost estimates) for GRS-IBSs and assumed alternative foundation systems. As part of this comparison, project specifications were evaluated to identify methods that may result in bids that are closer to EEs. In addition, this study aimed to determine some driving factors leading to differences in EEs and contractor bids. Although, only 13 projects were evaluated, with the majority selected because the bids seemed anomalous, some basic trends (or a lack thereof) were identified. |
