Wang, Y; Thangasamy, V K; Tiong, R L K and Zhang, L (2022) Improved workflow for precast element design based on BIM and lean construction. Journal of Construction Engineering and Management, 148(8): 04022065, ISSN 0733-9364
Abstract
Prefabricated concrete has substantial merits regarding a cleaner environment and less rework. However, precast concrete design suffers from an inefficient workflow. In this research, a new workflow is proposed by combining lean construction (LC) and Building Information Modeling (BIM) based on the plan-do-check-act (PDCA) framework. First, the current state value stream is built to obtain the root causes of waste. Second, an automatic precast element design engine (APEDE), including parametric BIM libraries, precast element design tool, and link for BIM model and precast element design tool, is developed to facilitate the precast design process. Finally, future state maps are introduced, with key LC principles and APEDE implemented in three case studies. Results show that the time efficiency and total man-hours are improved by more than 68.75% and 5.95 h, respectively. The proposed framework could improve efficiency and enhance the interaction and collaboration between fabricators and engineers.

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
