在过去的几十年里，劳动力驱动的建筑、工程和建筑(AEC)行业经历了令人担忧的劳动力短缺[[1]，[2]，[3]]。例如，在美国，80%的建筑公司找不到行业工人来填补职位空缺[4]。据报道，仅2020年1月，美国就有267,000个建筑职位空缺[5]。这个问题已经对AEC行业的生产率产生了负面影响，导致建筑项目的延误和成本超支[6]。在建筑业劳动力市场分析公司进行的一项调查中，超过90%的受访者报告称，由于劳动力短缺，2014和2015年的生产率较低[6]。异地施工和自动化等技术通过自动化施工过程提高了效率，这可以转化为行业内更高的生产率。生产率的提高可以缓解劳动力短缺[7]、[8]、[9]带来的部分压力。一方面，与传统的棍式建筑相比，异地建筑提供了许多好处，例如在受控环境中工作，并行进行活动的能力，以及改善建筑质量[[10]，[11]，[12]]。另一方面，建筑自动化包括计算机数字控制(CNC)、机器人和其他自动化机器的应用，这些技术在工厂环境中比在现场施工中更容易实施。例如，可以采用这些技术来支持建筑部件的制造和组装，否则将使手动操作自动化。此外，自动化可以将工人从危险和繁重的任务和/或危险条件中解救出来，从而提高安全性。
In the past decades, a concerning labor shortage is experienced by the labor-driven Architecture, Engineering, and Construction (AEC) industry [[1],[2],[3]]. For instance, in the United States, 80% of the construction companies cannot find trades workers to fill job positions [4]. Just for January of 2020, 267,000 unfilled construction positions were reported in the US [5]. This problem has impacted negatively the productivity in the AEC industry, causing delays and cost overrun in construction projects [6]. In a survey conducted by Construction Labor Market Analyzer, more than 90% of the respondents reported a lower productivity for the years 2014 and 2015 due to the labor shortage [6].Technologies such as offsite construction and automation allow greater efficiency by automating construction processes, which can be translated into higher productivity in the industry. This increase in productivity can relieve some of the strain imposed by the workforce shortage [[7],[8],[9]]. On the one hand, offsite construction provides many benefits over conventional stick-built construction such as working in a controlled environment, the ability to conduct activities in parallel, and improvement of the built quality [[10],[11],[12]]. Automation in construction, on the other hand, includes the application of technologies such as Computer Numerical Control (CNC), robotics, and other automation machines that could be easier to implement in a factory setting than in onsite construction. For example, these technologies can be adopted to support the fabrication and assembly of building components by automating otherwise manual operations. Moreover, automation can improve safety by saving workers from dangerous and heavy-duty tasks and/or in hazardous conditions.
