Multi-Criteria Decision Modeling For Best Value Selections In Target Value Design Integrated Project Delivery, Brent Patrick Griffis

Master's Theses

Integrated Project Delivery (IPD) combined with Target Value Design (TVD) is a better way to deliver value for the client than traditional guaranteed maximum price (GMP) methods. With traditional GMP delivery methods, the interests of the parties are often at odds. The goal of IPD is to align all party interests in order to achieve a win-win scenario. Due to the aligning nature of IPD and the fact that each party’s success is dependent on achieving the project objectives as a whole; a non-biased, transparent, decision-making process is necessary in order to deliver the project objectives within the constraints of …

Improving Enrollment In The Construction Management Graduate Program Through Students’ Perspectives, Mouloud Messaoudi

Master of Technology Management Plan II Graduate Projects

Low enrollment and the decrease in graduation and retention rates are challenges facing the growth of the Master’s in Technology Management – Construction Management (MTM-CM) program at BGSU. In addition, the competition between the universities to enroll and retain more in-state, out-of-state, and international students is aggressive. There is a need for a revaluation for the MTM-CM program in order to attract more students in the future. This study is a necessary step to know what the MTM-CM students think about the product delivered to them at BGSU. There was no prior study investigating the satisfaction level of the construction …
