Solution Overview
Problem
The challenge in earthworks construction sites is the reliable selection of efficient working methods to minimize emissions and energy consumption due to the diversity of sites and interactions with external activities, necessitating a method for determining location-specific as-built performance values.
Innovation Solution
A method is developed to determine an earthworks information model, locate tools within the construction site, and assess emissions, energy consumption, or elapsed time for specific work tasks, using satellite-based positioning and tracking devices, to provide accurate location-specific performance values.

1Object-generated harmful factors
If traditional earthworks construction methods are used without location-specific performance tracking, then general working methods can be applied, but emissions and energy consumption cannot be accurately minimized due to site diversity
Solution Approach 1:
The construction site is divided into multiple location-specific zones, and performance metrics (emissions, energy consumption, elapsed time) are measured and recorded separately for each location. This segmentation enables precise tracking of environmental impact at different work areas, allowing contractors to identify and optimize high-emission locations individually rather than treating the entire site as a single unit.
Solution Approach 2:
The system continuously collects location-specific performance data from earthworks machines and provides feedback to contractors about actual emissions, energy consumption, and time spent at each location. This feedback loop enables contractors to adjust working methods in real-time or for future projects to minimize environmental impact while maintaining productivity.
2Measurement precision
If comprehensive location-specific performance tracking is implemented, then emissions and energy consumption can be accurately measured, but system complexity increases due to multiple tracking parameters
Solution Approach 1:
The system uses universal tracking devices that can measure multiple parameters (emissions, energy consumption, elapsed time, location) simultaneously using the same hardware platform. Earthworks machines are equipped with multi-functional sensors and communication systems that collect all required data through a single integrated system, reducing the need for separate complex tracking devices for each parameter.
Solution Approach 2:
A centralized data processing platform acts as an intermediary that receives raw data from multiple sources (machines, satellites, sensors), standardizes the information, and presents processed performance metrics to contractors. This intermediary layer simplifies the complexity by handling data aggregation, validation, and presentation, allowing the tracking system to remain manageable while still capturing comprehensive location-specific performance information.
3Reliability
If location-specific as-built performance values are determined for all work tasks, then efficient working methods can be selected for future projects, but data collection time and processing requirements increase
Solution Approach 1:
The system collects and stores location-specific performance data during the actual execution of work tasks, so that when future projects require working method selection, the data is already available for analysis. By performing data collection in advance during construction operations, the system eliminates the need for time-consuming retrospective data gathering and enables rapid comparison of different working methods for future project planning.

AI summary
A method for determining a location specific as-built performance value in an earthworks construction site comprises determining an earthworks information model of the earthworks construction site, determining a location of a tool of an earthworks machine in the earthworks construction site and, respectively, in the earthworks information model, determining a work task in the construction site for the earthworks machine from the earthworks information model, determining, based at least in part on the location of the tool of the earthworks machine in the earthworks information model, a location specific part of the determined work task in the construction site, and obtaining as the location specific as-built performance value, from the earthworks machine, at least one of: emissions, energy consumption or elapsed time associated with the location specific part of the determined work task in the construction site.
