PurposeThe purpose is two-fold: (1) to explore the interactions of robotic systems and lean construction in the context of offsite construction (OC) that were addressed in the literature published between 2008 and 2019 and (2) to identify the gaps in such interactions while discussing how addressing those gaps can benefit not only OC but the architecture, engineering and construction (AEC) industry as a whole.Design/methodology/approachFirst, a systematic literature review (SLR) identified journal papers addressing the interactions of automation and lean in OC. Then, the researchers focused the analysis on the under-researched subtopic of robotic systems. The focused analysis includes discussing the interactions identified in the SLR through a matrix of interactions and utilizing literature beyond the previously identified articles for future research directions on robotic systems and lean construction in OC.FindingsThe study found 35 journal papers that addressed automation and lean in the context of OC. Most of the identified literature focused on interactions of BIM and lean construction, while only nine focused on the interactions of robotic systems and lean construction. Identified literature related to robotic systems mainly addressed robots and automated equipment. Additional interactions were identified in the realm of wearable devices, unmanned aerial vehicles/automated guided vehicles and digital fabrication/computer numerical control (CNC) machines.Originality/valueThis is one of the first studies dedicated to exploring the interactions of robotic systems and lean construction in OC. Also, it proposes a categorization for construction automation and a matrix of interactions between construction automation and lean construction.

The increasing demand for multifamily housing in the United States requires alternatives for building more affordable and sustainable housing to improve the quality of life for millions of families. Offsite construction (OSC) strategies may be a viable alternative for tackling this problem. Although the use of OSC is significant in the multifamily housing market in the world and it is also very promising in the US, a scarce amount of literature has focused on this topic. The purpose of this study is to identify specific factors that affect decisions on the use of OSC in multifamily housing in the US. Focusing on the sustainability dimensions of construction—social, environmental, and economic—the authors reviewed literature that was published between 2000 and 2019 and identified factors that are related to OSC adoption in general construction, in housing construction, and, more specifically, in multifamily housing construction in the US. Subsequently, a discussion on some important factors affecting decisions on the use of OSC in the American multifamily market is provided. The discussion focused on factors that, although important, have been under explored in the literature that addresses the use of OSC in multifamily projects, especially in the US, which are: customer’s attitude, building performance, and building comfort and indoor environmental quality (IEQ). In addition, a brief discussion regarding the importance of design to the uptake of OSC in multifamily projects is provided. This is one of the first studies dedicated to exploring the social, environmental, and economic factors that affect the use of OSC in multifamily housing in the US. The study also identifies research gaps, which serve as a roadmap for future research.

The architecture, engineering and construction (AEC) industry lags behind the manufacturing industry, both in terms of innovation and productivity, mainly due to its heterogeneous, fragmented nature and the uniqueness of its projects. This paper analyzes three effective processes and technologies which are carrying out great benefits to the construction industry: lean construction, automation, and modularization (LAM). The research consists of a systematic literature review and assesses previously published work related to the three combined topics LAM in construction with two main goals: (1) identify the relevance of the three topics combined for both the AEC industry and the academy, and (2) identify in the papers investigated the main themes related to the combination of LAM in construction. Findings reveal only 31 publications meeting the criteria within the two sources investigated. The most frequent areas of LAM identified in the papers were lean production management, optimization algorithm and prefabrication, respectively related to lean construction, automation in construction and modular construction. The results reveal a need to better investigate the interactions of LAM in construction as a way to promote the continuous improvement of the AEC industry.

Recent improvements in the AEC industry, such as Building Information Modeling (BIM) and lean construction and sustainability, require that the design and construction process be approached from a holistic and collaborative manner. From an academic perspective, collaboration also is an important teaching and research component that allows for a well-rounded understanding of the AEC industry. However, very little research has been performed on collaboration in the AEC disciplines, specifically interdisciplinary collaboration. As a starting point, this paper focuses on academic collaboration in journal publications related to sustainability and building performance. The authors provide bibliometric and thematic analyses of three 2018 research publications related to building performance and written by faculty affiliated with construction departments. The main goal of the paper is to provide preliminary findings about which AEC disciplines were included and which themes were prevalent in collaborative publications. Preliminary findings indicated themes related to performance analysis of buildings and / or building components; indoor environmental quality; decision-making and evaluation methods; and life cycle assessment. Results can be used to identify potential areas that are conducive to collaborative work between construction and other AEC disciplines in order to stimulate more interdisciplinary collaboration within AEC research.
