The construction industry has long sought automation due to high labor costs, which constitute nearly 50% of new single-family home construction in the US. Early attempts at automation date back to 1853 with Isaac Hussey's plastering machine. Despite continuous interest, widespread automation has been challenging to implement.
To understand the historical arc of construction automation, AI was used to analyze thousands of digitized issues of construction trade journals. Publications like Architectural Forum, House & Home, and Engineering News-Record, spanning from the mid-19th century to the early 1980s, were reviewed. The AI model, Claude (Opus 5 Max), searched for instances of construction tasks being automated within these archives and performed general web searches, including archives from the International Association for Automation and Robotics in Construction (IAARC).
The analysis identified two primary categories where construction automation has historically succeeded. The first category includes construction-related tasks performed off-site in a factory setting, such as steel fabrication, precast concrete production, and the manufacturing of windows and doors. The second category encompasses on-site tasks that are highly repetitive and can be executed by machines moving along simple, predictable paths.
Historically, automation efforts outside these two categories have largely failed to gain traction or achieve sustained success. This suggests that the inherent variability and complexity of many on-site construction tasks have posed significant barriers to automation that deviates from factory-like repetition or controlled off-site environments.

An analysis of historical construction trade journals, aided by AI, found that successful construction automation primarily occurs in two areas: off-site factory production of components and on-site tasks that are repetitive and machine-driven along simple paths. This research reviewed thousands of digitized journals from the 19th century to the 1980s to understand long-term trends in construction automation.
