The purpose of this study was to understand the time, cost, and construction intensity differences between DMC and the conventional Design-Bid-Build (DBB) delivery method. The study utilized semi-structured interviews (SSI) and quantitative data analysis for investigation. The study included interviews with employees from BLOX LLC (a firm specializing in the DMC delivery method) and includes an analysis of data collected on multiple free-standing emergency department (FSED) projects constructed using both the DMC and DBB delivery methods. Descriptive and inferential statistics were used to test hypotheses based on the two delivery methods' time, cost, and construction intensity performance factors to analyze the project data. The results suggested that DMC outperforms DBB in cost performance, supported by inferential statistics data (p≈0.00). Moreover, although inferential statistics do not show any significant difference between DMC and DBB (p > 0.05) concerning time and construction intensity performance, descriptive studies indicated that DMC still performs better than DBB in both these factors.Keyphrases: business model, delivery method, design manufacture construct, modular construction, performance In: Tom Leathem, Wes Collins and Anthony Perrenoud (editors).
