“…BIM can also be integrated with most environmental standards (e.g. BEAM Plus, BREEAM and LEEDS) for use in determining environmental compliance (Wong and Kuan, 2014;Kasim et al 2012;Azhar et al, 2011;Zanni et al 2014) Quick materials and quantities take-off allows easier calculation of environmental impact (Patlakas et al, 2015a).…”

“…The benefits of off-site manufacturing have been well-explored (e.g. Lawson et al 2005;Lawson et al 2014;Li et al 2016a;Kamali and Hewage 2016;Tam et al 2015;Patlakas et al 2015a). Common arguments for the off-site manufacturing choice over traditional construction on site according to the literature include improved quality, good health and safety and better working conditions, higher tolerances, lower costs and reduced labour reworks, lower construction waste, simplified construction processes, products that are factory tried and tested, predictable sustainability performance, better control and consistency in products and processes.…”

The need to overcome challenges faced by construction industry has been at the core of many government reports. Most of the reports suggest the adoption of innovations including off-site manufacture and emerging Building Information Modelling (BIM) to overcome the challenges facing the industry. Current research has largely focused on the impacts of off-site manufacture and BIM independently applied on traditional construction methods. Due to the factory-based nature of off-site manufacture, the benefits of BIM on off-site manufacture have been widely argued to be far greater than those of traditional construction. However, studies about impacts of BIM on off-site manufacture are scarce with far too many on traditional construction. This study investigates the implications of BIM systems on off-site manufacture and traditional construction methods, with emphasis on the technological potential of BIM for off-site manufacture. The specific objectives of the study are threefold. Firstly, it examines how BIM can support off-site manufacture. Secondly, the paper discusses the benefits of BIM and explains how BIM can overcome barriers hindering the uptake of off-site manufacturing. Thirdly, due to the importance to measure the benefits to support wider adoption, an examination of the published quantitative benefits of BIM on off-site manufacture and traditional construction is undertaken. A critical appraisal of the literature was undertaken to achieve the aim of this study. The main findings are the identification of qualitative and quantitative benefits of: BIM on off-site manufacture, off-site manufacture and BIM on traditional construction. The findings reinforce the argument that BIM adoption on off-site manufacturing projects is a rapid, efficient and one of the best ways to improve on the long standing challenges that have plagued the construction industry for generations.

“…Industrialized building, offsite construction, offsite fabrication, prebuilt construction, and prefabricated building are some terms used interchangeably in literature to describe prefabricated architecture-hereafter referred to as prefab. Significant research activities have focused on various aspects of prefabricated buildings, namely: realizing lean construction through off-site manufacturing [6][7][8], surveying the perspective of housebuilders on offsite construction trends [9], opportunities and constraints of offsite construction [10][11][12], policy-making [13], design solutions [14], software implementation potential [15][16][17], and future perspectives [18,19]. The recent UNFCCC COP 21 resolved to restrain increases in global average temperature to below 2˝C by reducing emissions, among others, towards sustainable development [20].…”

Performance of Modular Prefabricated Architecture: Case Study-Based Review and Future Pathways

Even though tightened building energy efficiency standards are implemented periodically in many countries, existing buildings continually consume a momentous quota of the total primary energy. Energy efficiency solutions range from material components to bulk systems. A technique of building construction, referred to as prefabricated architecture (prefab), is increasing in reputation. Prefab encompasses the offsite fabrication of building components to a greater degree of finish as bulk building structures and systems, and their assembly on-site. In this context, prefab improves the speed of construction, quality of architecture, efficiency of materials, and worker safety, while limiting environmental impacts of construction, as compared to conventional site-built construction practices. Quite recently, a 57 story skyscraper was built in 19 days using prefabricated modules. From the building physics point of view, the bulk systems and tighter integration method of prefab minimizes thermal bridges. This study seeks to clearly characterize the levels of prefab and to investigate the performance of modular prefab; considering acoustic constrain, seismic resistance, thermal behavior, energy consumption, and life cycle analysis of existing prefab cases and, thus, provides a dynamic case study-based review. Generally, prefab can be categorized into components, panels (2D), modules (3D), hybrids, and unitized whole buildings. On average, greenhouse gas emissions from conventional construction were higher than for modular construction, not discounting some individual discrepancies. Few studies have focused on monitored data on prefab and occupants' comfort but additional studies are required to understand the public's perception of the technology. The scope of the work examined will be of interest to building engineers, manufacturers, and energy experts, as well as serve as a foundational reference for future study.

“…Moreover, the fact that many of the timber offsite companies fall into the category of Small or Medium Enterprises (SMEs) means that often BIM adoption requires a sizeable investment in software and hardware, from which they often fail to see the desired Return On Investment (ROI), as discussed earlier [16]. This represents a lost opportunity: while BIM integration certainly comes with a number of challenges, it's immediate and potential benefits for offsite timber construction are considerable [102]. As such, the integration of ACC capabilities in the BIM workflow, with the respective savings in calculation and design time it brings, can contribute both to increase the BIM ROI for SMEs, and overall further the MMC agenda.…”

BIM-based tools can contribute to addressing some of the challenges faced by structural engineering practitioners. A BIM-based framework for the development of components that deliver Automatic Code Compliance (ACC) is presented. The structural design problems that such components solve are categorised as simple, where ACC can be implemented directly, or complex, where more advanced approaches are needed. The mathematical process of Multi-Dimensional Data Fitting (MDDF) is introduced in order for the latter, enabling the compression of complex engineering calculations to a single equation that can be easily implemented into a BIM software engineering package. Proof-ofconcept examples are given for both cases: offsite manufactured structural joists are utilised as a nonrecursive example, implementing the results obtained in the manufacturer's literature; the axial capacity of metal fasteners in axially loaded timber-to-timber connections are utilised as an example of recursive problems. The MDDF analysis and the implementation in a BIM package of those problems are presented. Finally, the concept is generalised for non-structural aspects at a framework level, and the challenges, implications, and prospects of ACC in a BIM context are discussed.
