Where Has Construction Automation Been Successful?
Construction is famously labor intensive: direct labor makes up close to 50% of the cost of constructing a new single-family home in the US, compared to around 6 to 8% of the cost of manufacturing a car.
Successful construction automation typically falls into two main categories. The first category includes construction-related tasks that can be performed off-site in a factory setting, such as steel fabrication, precast concrete, and window and door manufacturing. These activities benefit from the controlled environment and ability to mass-produce components, resulting in higher efficiency and cost savings.
The second category consists of on-site tasks that can be made highly automated, resembling a factory-like environment. These tasks involve machines moving along a predetermined path and executing repetitive motions consistently. Examples include concrete pouring, bricklaying, and asphalt paving. By automating these repetitive processes, construction sites can achieve greater precision, speed, and reduced labor requirements, ultimately lowering overall costs.
In contrast, attempts to automate tasks that are not conducive to these categories have generally failed. For instance, operations that require a high degree of flexibility, human judgment, or adaptive responses have proven challenging to automate successfully. Consequently, the history of construction automation suggests that focusing on off-site and highly repetitive on-site tasks yields the most promising results.
