Lu, Y and Zhu, Y (2021) Integrating hoisting efficiency into construction site layout plan model for prefabricated construction. Journal of Construction Engineering and Management, 147(10): 04021130, ISSN 0733-9364
Abstract
Construction site layout plans (CSLP) are vitally significant to prefabricated construction project management; in particular, abundant hoisting operations reinforce the importance of the location of tower cranes and precast component supply points. However, previous studies on CSLP have been conducted on traditional construction sites, and there is a gap in the research regarding the prefabricated construction site layout plan. This paper attempts to establish a comprehensive CSLP model to optimize the facility layout problem on prefabricated construction sites, integrating the hoisting efficiency of precast components into previous studies on CSLP considering safety risks and transportation cost. To solve the proposed multiobjective model, the Genetic algorithms (GAs) is applied to obtain Pareto optimal solutions due to its strong global search capability. To verify the feasibility and effectiveness of the proposed model, a prefabricated residential building project is studied as a case study. This paper attempts to improve the CSLP model for the scene of prefabricated construction in the preconstruction stage to optimize safety risk, transportation cost, and hoisting efficiency, which may facilitate future research attempting to improve the prefabricated construction site layout considering more complex actual situations.

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
