Summary

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 with 8 confirmed deployments across the Netherlands, with a UK trial planned for 2025.

How it works on your site

Corner and Lead Construction

The three-robot team drives itself to the work location, aligns to the digital twin using camera-based localization, and builds wall sections course by course. Two support units shuttle mortar and bricks to the bricklaying robot. A human bricklayer supervises and handles mortar pointing, wall ties, and rain protection while the robot places bricks.

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.

Will it work on your site

Environment Outdoor, dry weather only Must be moved indoors during rain
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.'
Site preparation Photogrammetric 3D scan + digital twin alignment Duration not quantified; performed by Monumental staff
Autonomy Supervised: autonomous navigation and brick placement. Mortar pointing and wall tie installation performed manually by a human worker alongside the robot.
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.
Business model Subcontractor service. Monumental deploys robots to site and charges per brick laid at rates comparable to manual bricklaying (approximately £1 per brick in UK market). Contractors do not purchase or operate the robots.
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.
