“…-Reduce delivery waiting times: AVs can deliver materials to the job site more frequently and more accurately, decreasing the wait time for materials to arrive, and cutting logistic costs (Xiaosheng & Hamzeh, 2020). AVs are able to calculate the most efficient route to the job site independently and can travel non-stop, which reduces travel time.…”

In the automotive industry, autonomous vehicles (AVs) are an advanced innovation that has the potential to revolutionise the existing transportation system significantly. In addition, AVs provide benefits for society, the economy, and the environment. As far as Lean Construction (LC) is concerned, these features appear promising. LC's primary objective is to minimise the waste of resources, time, and effort. This study examines the potential contribution of AVs to LC through two exhaustive rounds of literature review. The research aims to establish the links between AVs and the overarching LC philosophy and principles. The first round of the literature review identified that AVs could reduce waste in three areas: inventory, transportation, and waiting time. Moreover, they can support solutions to environmental concerns. Additional literature reviews have identified five potential approaches for a new technology that can be applied to the construction industry to enhance the implementation of AVs. As well as the anticipated developments in each case are discussed accordingly. The practical implications of the findings are that AVs can reduce waste and cost, increase efficiency and productivity, and help create a more sustainable construction industry. According to the study, the construction industry should take a proactive approach to implementing AVs.

“…On the other hand, some studies have analyzed the benefits of using prefabricated components together with BIM and standardized processes. These studies have found increased performance in construction, such as reduced rework, reduced lead time, and better productivity (Xiaosheng & Hamzeh, 2020;Schimanski et al, 2021). Nevertheless, existing literature does not contain quantitative performance metrics.…”

The implementation of the Last Planner System (LPS) and off-site construction has been identified as means to improve production management and, thus, increased productivity and project performance. Nevertheless, the sector lacks an evaluation system that allows clients, designers, and contractors to identify areas for continuous improvement and encourage further adoption of the LPS and off-site manufacturing. Therefore, this paper aims to analyze performance during the construction of the reinforced concrete structural frame of two similar high-rise residential projects in Lima-Peru. Both projects used the LPS. However, the first case used traditional on-site poured slabs, and the second used a mix of precast slabs and additional on-site pouring. Data was collected during the construction process and included labor data, production data, schedules, site visits, and observations. Data were analyzed to obtain cycle times, production and productivity rates, and labor density. The results show that the building using precast slabs performed 14% better in terms of time and 16% in terms of productivity compared to the traditional slab. Further research can measure performance and productivity by implementing other precast components such as shear walls, beams, and columns.
