This case study exposes students to situations in construction that require ethical decision-making. It builds upon knowledge acquired through construction management education and practice. In the case study, Allied Constructors has received a contract for the construction of a laboratory building on a university campus. Several ethical dilemmas are presented together with the responses of parties involved, and students are asked to analyze the situations and propose solutions. The individual situations are grouped into four major project phases: (1) preconstruction, (2) subcontract solicitation and award, (3) project execution, and (4) project close-out. Teaching Notes for the instructor are provided to assist in using the case study.
