Monumental builds construction robots that are supplied bricks by electric autonomous ground vehicles (AGVs) moving around site.
Monumental was founded as Terraform in 2021 by chief executive Salar al Khafaji and chief technology officer Sebastiaan Visser with a vision to solve the labour, cost and sustainability challenges facing the construction industry.
It has now raised US$25m in funding led by Plural and Hummingbird. Northzone, Foundamental and NP-Hard Ventures, as well as angel investors, also participated.
Monumental鈥檚 robots are fitted with sensors and small cranes able to place bricks and mortar with human-level precision, accuracy and efficiency, it is claimed. The robots are controlled by Monumental鈥檚 AI-powered software, Atrium, and are small enough to go anywhere a human can, whether that鈥檚 in tight corners, through doorways or in a van.
Following pilot test cases in the Netherlands, Monumental completed its first large-scale, 15-metre facade for an office and warehouse building in 2023. It has since deployed its robots on several other projects, including social housing and has partnerships with multiple contractors.
