Maintenance
Veolia manages complex industrial infrastructure in Belgium. The primary scope of this project was to simplify and modernize maintenance procedures specifically for industrial boilers across various Veolia locations. By replacing a bulky, 300-page paper manual with intuitive Augmented Reality (AR) instructions, the new mobile application aimed to minimize human error and significantly boost field technicians’ efficiency.
01
Overview
The Challenge: From Static Manuals to Dynamic Operations
Veolia’s field technicians relied on heavy paper-based operational playbooks (draaiboek) to carry out complex boiler maintenance. During time-critical interventions, technicians had to constantly cross-reference paper instructions with the physical machinery.
Key challenges included:
- Process inefficiency: Manual cross-referencing slowed down critical procedures.
- Operational risk: Complex, multi-step procedures had to be executed with high precision under pressure.
- Limited adaptability: Fixed paper workflows could not easily accommodate different operational scenarios.
02
The Solution
Spatial Guidance for Field Technicians
Tapptic developed an Augmented Reality mobile application using Unity, optimized for ARCore-compatible Android devices. The app brings maintenance instructions directly into the technician’s field of view.
- Spatial Instructions: QR markers placed on the boilers serve as spatial anchors, placing digital instructions precisely over the physical components.
- Contextual Interface: Visual callouts, highlights, and reference frames guide the technician’s focus, showing exactly where to look and what step to take next.
- Adaptive Scenario Branching: Conditional flows adapt to real-time situations, allowing technicians to follow scenario-specific paths based on existing operational logic.
03
The Outcome
The solution transformed complex boiler maintenance into an interactive, context-aware workflow:
40% reduction in intervention time: Streamlined workflows significantly accelerated field operations.
Reduced risk of human error: Spatial guidance and conditional workflows made complex procedures easier and safer to execute under pressure.
All critical procedures in one interface: Consolidated multiple operational manuals into a single, intuitive mobile application.
