About Monumental
Monumental is an Amsterdam-based technology company that automates on-site construction through a combination of autonomous robotics and custom software. The primary objective is to transition building processes toward a software-defined model where structures can be assembled rapidly with minimal manual intervention. By focusing on masonry and facade construction, the platform provides a vertical solution that handles the physical installation of bricks on active construction sites. The robots operate using an integrated stack that includes machine vision for navigation and real-time motion planning, enabling the construction of bespoke architectural designs that would typically require extensive human labor. The engineering approach treats hardware as a modern distributed computing system. Instead of relying on traditional industrial components like PLCs, the robots utilize Intel NUCs, Nvidia GPUs, and a communications infrastructure based on Power over Ethernet. Most of the control software is written in Rust to balance high-level abstraction with efficient low-level execution. Additionally, the company employs a 3D digital twin system written in TypeScript and WebAssembly, which allows project planners to simulate robotic paths and structural builds in a web browser before any physical work commences. This enables a rapid iteration cycle where both hardware and software improvements are deployed frequently. The solution is designed for residential developers, civil engineers, and construction firms looking to increase productivity and address labor shortages. It has been successfully deployed for projects involving house facades and canal retaining walls in the Netherlands, with further pilot programs expanding into the United Kingdom. By using autonomous units that can navigate the unstructured environments of a building site, the technology offers a more flexible alternative to fixed industrial robotics. It is particularly suited for organizations that manage large-scale brickwork and require high levels of precision and speed. What makes Monumental unique is its complete ownership of the technology stack, from microcontroller prototyping to final robot assembly. Unlike many construction tech firms that focus solely on software, Monumental maintains an in-house workshop to build and refine its hardware prototypes. This vertical integration allows the team to solve engineering problems at the most appropriate layer, whether that is through a software update or a mechanical adjustment. The company operates as a service provider, supplying both the robotic units and the necessary technical deployment teams to ensure successful project outcomes on real-world sites.
Monumental FAQs
Where is Monumental currently operating?
Monumental is currently active on construction sites throughout the Netherlands. They are also expanding their reach by initiating pilot projects in the United Kingdom.
What technologies power the robotic systems?
The robots are built using a modern stack featuring Nvidia GPUs, Intel NUCs, and control software written in Rust. They use Power over Ethernet for internal electronics and custom machine vision pipelines for navigation.
What types of projects can these robots handle?
The technology is designed for on-site masonry, specifically building facades for residential houses and structures like canal retaining walls. The goal is to deliver bespoke, software-defined buildings with minimal manual labor.
How does the digital twin system work?
Monumental uses a 3D simulation and digital twin platform that runs directly in the browser using TypeScript. Rust-based path planning code is compiled to WebAssembly to provide high-performance simulations of the robots' movements.
Is Monumental available as a remote software product?
No, Monumental provides a vertically integrated service where they deploy their own hardware and operators to construction sites. Their focus is on delivering physical outcomes, like brick walls, rather than selling software alone.
