Relative Importance of Subcontractor Selection Criteria: Evidence from Singapore
Publisher: American Society of Civil Engineers
Abstract: Subcontractors carry out a large portion of the work done in construction projects. Thus, selecting the right subcontractor essentially contributes to the project’s success. We designed a choice-based conjoint experiment ...
Modeling Cost Impacts and Adaptation of Freeze–Thaw Climate Change on a Porous Asphalt Road Network
Publisher: ASCE
Abstract: Changes in weather patterns pose a threat to the serviceability and long-term performance of roads, and porous asphalt (PA) roads are particularly sensitive to the freezing-thawing (FT) phenomenon. The main objective of ...
