Memarian, B and Mitropoulos, P (2014) Production system design for speed and reliability: A case study in concrete construction. International Journal of Construction Education and Research, 10(3), pp. 181-200. ISSN 1557-8771
Abstract
This case study investigates the production practices of a "High Reliability" (HR) concrete supervisor-a supervisor who consistently achieves exceptional production and safety performance. The case describes how the supervisor designed the production system to build the concrete frame of a 10-story building under an accelerated schedule and under severe weather conditions. To shorten the operation's duration, the supervisor selected formwork systems that reduce installation time, and overlapped the concrete activities by reducing the "batch size," and by using dedicated crews for deck and vertical concrete. However, the overlapping increased the dependencies between activities, and any deviation from the plan could impact the entire process. In order to create a reliable workflow and mitigate the effect of deviations, the supervisor used several strategies that addressed: (1) the organization of the production process; (2) the activity design; (3) resource management; and (4) crew management. These strategies converged to create a fast and highly reliable work system, and achieved an accelerated schedule with minimum waste and excellent safety results.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
