Infrastructure progress and survey data analytics system
The specialist compares the infrastructure work plan with geodetic and other measurements. Visible differences in quantities or geometry help to verify actual progress.
Measurements of different dates and methods are compared without matching the area, original surface and the amount of work defined in the contract. The difference in geometry is presented as work done, although it may be partly due to other activities or measurement error.
How the solution works
- The team describes the amount of work to be determined, records the initial condition and provides for the boundaries of the area being measured.
- Measurement is accepted with date, method, deduction and eligibility check.
- Comparable compatible surfaces or other objects are compared, distinguishing the invisible and unreliable part.
- The specialist evaluates what the difference really says about the chosen work.
- The validated estimate and its limits are transmitted to the project review, preserving the basis of the previous comparison.
Key challenges
- Progress is measured periodically
Solution capabilities
Work-Measure Relationship
The planned quantity is associated with the actual measured volume, its unit, and the required contractual definition.
Eligibility of measurements
The data is checked against a reference, time, method and control basis; accuracy is not predicted solely by the type of device selected.
Comparison of geometry
The difference is calculated for a comparable territory or element, marking the covered, unmeasured, or changed portion of the volume.
Interpretation of quantity
A change in surface or shape is assessed in conjunction with the nature of the work. Stored material or temporary relief is not necessarily acceptable work done.
Validation of estimate
The specialist confirms the result or returns it to be corrected. The project team together receives information on what territory and works are measured and what calculation limits.
Business context
- Progress is measured periodically
- Measurements of different dates and methods are compared without matching the area, original surface and the amount of work defined in the contract. The difference in geometry is presented as work done, although it may be partly due to other activities or measurement error.
- Scope of work performed is based on measurements
- The customer and contractor need a common framework to discuss progress and quantities made. Proper geodetic data allows the difference between plan and actual situation to be verified. The validated estimate facilitates the acceptance of works and helps to address deviations in time before they affect other stages.

Potential impact (%)
The ranges indicate an illustrative relative change in the metric under the stated assumptions. Results depend on the starting position and actual use of the solution. Percentages for different metrics must not be added together.
Volume comparison and control work
12–36%Decreasing
This illustrative scenario assumes that 30-60% of manual data entry and handover work can be addressed. That share is assumed to fall by 40-60%. Company data is needed to verify both the addressable workload and the resulting change.
The active time of comparison and specialist verification for the same type of work and eligibility requirement is measured.
Time to proper progress estimate
6–25%Decreasing
This illustrative scenario assumes that 20-50% of waiting caused by missing information or unclear responsibility can be addressed. That share is assumed to fall by 30-50%. Company data is needed to verify both the addressable share and the resulting change.
The time between measurement and usable estimate is compared, separating the frequency of measurement and subsequent data processing.
Conditional calculation scenarios. The assumptions have not been validated against client measurements.
When this solution is relevant
- The report presents the surface difference as ground work has been done, although part of the change consists of a temporary pile of materials.
- The percentage of progress is given for the entire section, although reliable measurements only cover part of its territory.
Implementation requirements
For the analysis of progress, specialists confirm the methods of measurement suitable for the works, the initial state and the limits of the sections to be evaluated. Data and errors of different dates are checked against the control basis before using the results for the acceptance of the works.
Further development options
- Incorporation of other properly measurable types of work after control comparison
- Sequence of period images to examine the specific cause of the confirmed deviation
