A clearance conflict discovered during movement is already too late.
Drawings may not match the current physical railway, and the critical point may be very local. Measurement removes that assumption.
Before: clearance is inferred from drawings or nominal dimensions.
After: critical locations are measured against the actual requirement.
The product is only useful when it fits the real railway job.
CBP chooses the measurement architecture, coordinates the principal engineering route and keeps the vehicle envelope, track reference and survey output connected.
