Conceptual framework for off-site roof stacking construction

Abstract

A B S T R A C TA great deal of interest in off-site construction has been remarkable over the last decade. However, building on the rooftops of existing building has not been given a significant importance as a subject of research, despite its dependence on off-site construction and prefabrication. Thus, this paper develops a novel conceptual framework to support a multidisciplinary decision making for selecting off-site prefabricated constructional system for roof stacking. The multidisciplinary approach includes each of safety, logistics, cost, time, environmental impact, and quality of construction as major criteria in the decision making process. This paper is the outcome of an exhaustive investigation of more than 136 roof stacking projects built during the last 20 years. The development of framework is supported by a feedback validation loop based on semi-structured interviews with experts in the field of roof stacking and off-site construction.

Modular composite building in urgent emergency engineering projects: A case study of accelerated design and construction of Wuhan Thunder God Mountain/Leishenshan hospital to COVID-19 pandemic

“…It is estimated that by 2022, modular products will grow by 6% globally, and some of these countries are already leading the way in prefabricated buildings [ 9 ]. Sweden is a model of modular home architecture-84% of individual houses in Scandinavian countries use prefabricated timber structures [ 10 ]. In the United States, Australia, and the United Kingdom, this figure is only 5%.…”

“…Through this project's approach, the rationality of structure selection and reliability of the design is verified. Raytheon mountain's implication is that as buildings with “more functions than everything,” [ 25 ] they are not built for the sake of passing on. Still, because of the unique time point and the witness of the whole people in the live broadcast, they may also be recorded in architectural history [ 26 ].…”

Design for Manufacturing and Assembly: A BIM‐Enabled Generative Framework for Building Panelization Design

“…Such a proposed framework, it should be noted, is intended to assist in selecting the optimal prefabrication level for countries or regions rather than individual building projects. Another interdisciplinary decision-making framework for selecting a prefabricated constructional system for roof stacking was developed by investigating 136 case projects and semistructured interviews [27]. Various factors, such as safety, logistics, cost, time, environmental impact, and construction quality, were considered in this framework.…”

An integrated method of automated layout design and optimization for modular construction

“…In modular construction, module units or modules, are volumetric components that are assembled in the factory, transported as a whole box and joined on-site by inter-modular connections (Amer et al, 2019). Through standardization, modules are expected to be used across different projects and save costs compared with traditional projects (Mohamad et al, 2013).…”
