A coordinated digital baseline simplified complex airport infrastructure upgrades and planning

The brief

A 2 lakh sq ft commercial airport that needed a coordinated digital baseline. The operator was planning a new baggage handling system, wanted better visibility into MEP for leakage and service routing, and had no reliable consolidated as-built documentation for future upgrades.

Why it was risky

Operational airports are difficult environments to model. Drawings drift from as-built quickly; MEP systems are routed across multiple legacy upgrades; and any new package — like a baggage handling system — needs spatial accuracy that a paper drawing record cannot provide.

• Baggage system integration required an accurate as-built 3D model to design and install against.
• MEP visibility was the second-largest gap — leakages and service routing could not be assessed without scanning.
• Documentation deficit meant every future upgrade would have started by re-surveying the same spaces.

What Observance did

• Scan-to-BIM modeling delivered a high-accuracy as-built BIM model for infrastructure planning.
• MEP digitisation structured and digitised the service systems so they could be queried, not just viewed.
• Automated workflows reduced turnaround time on the scan-to-BIM cycle.
• BIM coordination and QC ensured the model was accurate enough for downstream design decisions.

Outcome

Faster design decisions on the baggage integration package; manual verification eliminated across the MEP scope; a single source of truth established for the operator's future upgrade programme.
