Lab exercises have traditionally been a time when students follow a given procedure, collect data, and interpret the data. The highly structured experience often leads to students focusing on the procedure and not fully thinking through the concepts being covered. While labs are fully completed each week, the structured approach does not prepare students for the open-ended, non-procedural work entry-level engineers will encounter in industry. To encourage a deeper understanding of course concepts and how they translate to physical systems and better prepare students for the workforce, open-ended design projects were offered in place of structured labs in the circuits and mechatronics courses at James Madison University. The design projects are undirected experiences that build on the directed experiences in lecture and lab. Students are challenged to work in teams to design, build, test, and in one case, calibrate, an electrical system. No instruction is provided for the project, rather, a set of design requirements, timetable, and supplemental materials (e.g., data sheets, vendor design briefs, past labs relevant to the design requirements) are given. Students must synthesize multiple weeks of course content into a single design project. This paper reports on our observations and student feedback for embedding design experiences in engineering science courses.

Performance in the construction industry is wrought with challenges and owners often are victim to cost and schedule overruns, particularly on high profile projects that are large, complex, and risky. Alternative project delivery methods and techniques are continually being developed and implemented by buyers of construction services to address these problems. The Best Value Business Model (BVBM) has been rigorously tested and shown to improve project performance via its three-phased approach to project delivery. BVBM increases performance throughout the construction project lifecycle by utilizing value-based selection processes, pre-contract planning methodologies, and performance measurement systems. The objective of this research is to provide a detailed case study of BVBM application on a design-build project to deliver a highly complex research facility with tight schedule and budget thresholds. The implementation process is discussed in detail and project results are provided and analyzed to demonstrate the ability of BVBM to improve project performance. Special attention is paid to the ability of BVBM to optimize project cost and schedule performance through the application of a value-based selection methodology, a pre-contract preplanning period, and a weekly risk management system.

The use of Alternative Technical Concepts (ATC) is becoming widespread in design-build transportation projects in the United States. According to Federal Highway Administration (FHWA) ATC is a request by a proposer (usually in design-build projects) to modify a contract requirement for gaining competitive advantage over competition. The owner, usually a state department of transportation, requires that the ATC provide a better or at least equal solution to the owner’s design requirements. In Design-Build (DB) projects, the ATC is usually proposed by a proposer during the Request for Proposal (RFP) process and is considered in the evaluation and selection of the proposers in conjunction with the Best Value (BV) method of selection. In this paper, the authors have focused on two case studies involving ATC implementation and negotiations with the Massachusetts Department of Transportation (MassDOT) highlighting advantages and disadvantages of using ATC in DB contracts. In each case, the nature of ATC and the approval process is discussed. In the first case, the approved ATCs provided the proposer with a clear advantage in winning a contract with the agency despite not being the low bidder. In the second case, the proposed and approved ATCs did not result in winning a contract despite being the low bidder.
