How it works on your site

The Monumental is a compact, wheeled, battery-powered bricklaying robot that operates as part of a three-machine team: one bricklaying unit with two arms (mortar and brick) plus two support robots for material transport. It places bricks autonomously using camera-based localization against a digital twin, covering facade construction, retaining walls, and standard masonry; pointing, wall ties, and finishing stay with a human bricklayer on site. Monumental has been shipping since 2023.

Corner and Lead Construction

Monumental's robots build the corners of a wall along with the straight runs, following the bond pattern and leaving the gap where a window frame goes. The robot stops where a lintel is needed, and a mason steps in to set it.

Unit Placement (Brick/Block/Stone)

The bricklaying arm places each brick in world-space coordinates, cross-referencing camera input with the digital twin. Integrated cameras monitor every placement and self-correct; the system detects bricks under partial obstructions, shadows, and glare. A human bricklayer handles mortar pointing and wall ties, tasks the robot does not perform.

    A Monumental bricklaying robot laid several walls as a trial at SEIN's new day activity center site in Cruquius, with contractor Pellikaan supplying mortar and bricks; the trial caused no construction delay.

Will it work on your site

Terrain
Construction site ground: bumpy, gravelly, sandy. Chunky rubber wheels with autonomous navigation.
Working height
Ground floor height using onboard cranes. Higher floors reached via scissor lift.Specific numeric heights (6 m, 12 m) and RECO platform name not independently confirmed.
Throughput
Around 500 bricks per 8-hour shift (approximately 62.5 bricks/hr)
Transport
Fits through standard doorways; fits inside a van
Power
Electric'Battery' specifically not confirmed by independent sources; robots described as 'small, electric AGVs.'
Autonomy
Supervised: autonomous navigation and brick placement. Mortar pointing and wall tie installation performed manually by a human worker alongside the robot.
Show all 9
Control
Atrium software (proprietary). AI-powered construction robot operating system.Specific feature list (design, build control, monitoring, fleet management) sourced from vendor documentation.
Operator
Supervisor does not need bricklaying qualification. Supervisor-to-machine ratio varies by source (one per machine or one per two machines). A separate human worker is required for mortar pointing and wall tie installation.
Fleet composition
Three-robot team per deployment: one bricklaying unit (dual-arm, brick and mortar) plus two supply wagons (one for bricks, one for mortar).Supply wagons require manual reloading during shifts.
