Digital Facility Log: Socializing Industrial Maintenance
How we translated physical logbooks and disjointed checklists into an iPad-first, social-media-style remote operations workspace for engineers.
NDA & Simulation Notice
This project was executed under a strict Non-Disclosure Agreement (NDA). The interactive panels and dashboard mockups shown below represent sanitized, functional wireframes designed to simulate the core system logic and information architecture without disclosing proprietary client data. High-fidelity UI designs and case files are available upon request.
Industrial facility management historically relied on physical paper logbooks kept in machine rooms. When a technician completed maintenance on a chiller or pump, they noted details in a handwritten binder.
Because these logs were offline, client service managers, facility directors, and remote energy engineers worked in the dark. Problems went un-correlated, recurrence patterns were invisible, and managers struggled to track technician handoffs.
The **Digital Facility Log (DFL)** re-engineers this logbook into a dynamic digital hub. Designed by Proto UX under Principal Young Ryu, Ph.D., the product vision translates manual logs into an active, social-media-styled collaboration feed. This workflow integrates remote service specialists and local building technicians, aligning priorities and status checks across Siemens Activity Central.
Tablet-First Design Considerations
Screen Constraints
The workspace is optimized for the smallest iPad resolution (**1080x810**). The layout uses a one-dimensional left-only navigation menu (no top navigation) to maximize content width on touch devices.
Touchscreen Friendly
Designed strictly for finger targets with no hover-state assumptions. Navigation uses simple tap triggers and visual pop-up lightboxes to inspect logs, keeping the page hierarchy to a single level depth.
Social Feed Metaphor
Adopts UI styles found in **Facebook, Discord, and Slack**. Rather than static databases, maintenance updates are posted as social logs (latest on top) with checklists, attachment hooks, and equipment tagging.

Structuring the DFL Solution
Transitioning static facility logs to a social activity log solved several key problems identified in Young Ryu’s user discovery process.
Remedy for Technician Rotations
Because technician rosters shift constantly across facilities, the DFL feed serves as a running chronological binder of the building's status. Any incoming engineer inspects the latest pins and checklists, getting up to speed without reading physical scrap notes or spreadsheets.
Proactive Alarm & Priority Sync
To maintain backend cohesion, the priority attributes (High, Medium, Info) and state triggers synchronize automatically with **Siemens Activity Central**. Incidents from building automations write directly to the DFL feed, notifying facility directors before hot/cold complaints trigger.
Remote Diagnostics Binders
A key finding in the user discoveries was the need to troubleshoot hardware remotely. By including support for geocoded QR scanner codes to inspect machine sheets, and implementing **acoustic waveforms analysis** (listening to equipment room hums to isolate minor bearing misalignments), we designed a workspace where engineers diagnose building issues safely from home.
