RESULTS Case 1 description Modular construction project Our first case was an in-house industrial modular construction project located in the Southeastern United States. The contracted price of the modular unit under construction was $13 million, which was about 95% complete during the time of visit. The project
had accumulated more than 82,000 worker-hours and had 14 work-crews actively involved in the project during the study. During the visit upper-management assigned two safety personnel with a total of 18 years of experience to facilitate data collection and the integration of the SMQM intervention. Three crews specializing in three different trades (structural,
electrical, and piping) were selected from a stratified population to participate in the multiple baseline testing. The size of each crew ranged between 8 and 14.
