Hou, C., & Remoy, H. (2021) · Digital Twins to Enable Smart Heritage Facilities Management: A Systematic Literature Review

Using reality capture to eliminate data blind spots in complex buildings and industrial spaces.

Hou & Remoy examined how reality-capture technologies — drones, photogrammetry, and LiDAR laser scanning — solve one of FM's oldest problems: the gap between what the drawings say and what actually exists on site. In complex buildings, boiler rooms, and industrial facilities, as-built documentation is often decades out of date. Reality capture creates accurate, navigable 3D records that support lifecycle cost planning, structural health monitoring, and accurate maintenance scheduling.


Original quote

"Reality-capture data enables FM professionals to move from assumption-based maintenance planning to evidence-based lifecycle management, significantly reducing long-term capital expenditure." — Hou & Remoy (2021)

What this actually means

1

Most FM teams manage buildings based on drawings that no longer reflect reality — every undocumented modification is a future cost risk

2

LiDAR scanning and photogrammetry can capture an entire building's current state in days, producing millimetre-accurate 3D point clouds that become the single source of truth

3

Reality-capture data directly feeds into lifecycle cost planning: knowing exactly what assets exist, where they are, and in what condition enables accurate capex forecasting

4

For heritage and industrial buildings — where modifications are frequent and drawings are unreliable — reality capture is not a luxury but a risk management tool

5

The data created is not a one-time deliverable: it becomes the foundation of a continuously updated Digital Twin as the building evolves

What you could do with this

A guide to scoping a reality-capture project: what to scan, what output formats to request, and how to use the data in FM workflows

A lifecycle cost modelling tool that uses asset condition data (from scans or surveys) to project 10–20 year capex scenarios

A case study template FM freelancers can use to document the value of a reality-capture project for a client
