Decisions you can trust.
NTRO’s Infrastructure Measurement provides the foundation for confident decision-making, giving asset owners and operators timely, trusted insight across the full infrastructure lifecycle.
NTRO’s Infrastructure Measurement delivers services that provide the insight needed to plan, prioritise and manage your network with confidence.
Surface condition only tells part of the story. Our structural assessment services reveal how pavements are performing beneath the surface, helping asset owners identify hidden weaknesses, predict deterioration and make more confident maintenance and renewal decisions before failures occur.


Independent dilapidation surveys provide an accurate record of infrastructure condition throughout the project lifecycle. By documenting asset condition before, during and after works, we help reduce disputes, protect stakeholders and provide confidence that infrastructure is being managed responsibly.


Line marking reflectivity assessments measure how effectively road markings remain visible to drivers, particularly at night and in wet conditions. Our high-speed assessments help identify where remarking is needed, supporting safer roads and more effective maintenance planning.


Ride quality assessments measure pavement smoothness to understand how roads are performing for users. The results support maintenance planning, network monitoring and construction quality, helping asset owners improve performance across the road network.


Skid resistance testing measures how well road surfaces perform in wet conditions, helping identify locations where reduced friction may increase risk. The insights support proactive maintenance and targeted safety improvements across the network.


Understanding the condition of unsealed roads is essential for effective maintenance and long-term planning. Our assessments provide reliable condition data to help prioritise grading, identify deterioration and make better investment decisions across regional and rural networks.




Using truly world-leading capability, and a secure, cloud-based pipeline, the system captures, validates and delivers infrastructure intelligence faster, and with greater accuracy than traditional survey approaches.
