ROBOTIC BRICKLAYING AND 3D PRINTING ROBOTS IN CONSTRUCTION: AUTOMATING MASONRY WORK AND BUILDING STRUCTURES LAYER BY LAYER, AND ROBOTIC WELDING IN CONSTRUCTION (ENHANCING PRECISION AND EFFICIENCY IN STRUCTURAL STEEL WORK)

The construction industry undergoes a radical transformation through emerging robotic
technologies which include robotic bricklaying and 3D printing and robotic welding. The
construction activities undergo transformation through these technologies which boost
productivity and safety standards while reducing material waste and enhancing precision. This
paper examines the technological advancements of these systems and their deployment on
construction sites and their effects on project results including time, cost, quality and health
and safety. The analysis through case study and comparison demonstrates how automation
affects workforce participation and project duration and sustainability targets while showing
the extensive transformation caused by automation. The paper demonstrates how robotics
unite with digital technologies including BIM and IoT to establish Construction 4.0 which will
develop an efficient agile resilient construction industry based on data. The research identifies
the need for proactive adaptation strategies to achieve full technology realization because it
recognizes construction as a human-machine collaboration.
