Cal Poly Craft Center Wedging Tables, Cooper Christopher Strong
Construction Management
The Craft Center, located on Cal Poly's campus, is where students can unwind from stressful coursework and engage in activities like pottery, surfboard shaping, and stained glass. The pottery studio needed new wedging tables, which are essential for removing air from clay before shaping it. The project involved building two new 7’ x 2.5’ tables that would fit well in the space and be durable. Designed to be 33” tall, these tables are accessible to students of varying heights. They feature a concrete surface that is both durable and porous, helping to absorb some moisture during use. The previous tables …

Enhancing Pricing Practices Of Subcontractors: A Comparative Analysis Using Simulation Modeling, Muaz O. Ahmed, Islam H. El-Adaway, Kalyn T. Coatney
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
The construction industry often relies on subcontracting, where subcontractors bid for portions of a project before general contractors bid for the entire project in a process referred to as multi-stage bidding (MSG). MSG can be complex, and winning bidders may be burdened with underestimating their bids and encountering the winner's curse. Despite various studies investigating this issue, further research is necessary to examine bidding strategies for subcontractors. This paper addresses this research need by exploring and comparing how bidding strategies based on reinforcement learning and game theory could aid subcontractors in mitigating the winner's curse in MSG. The authors used …
