This document specifies requirements for data exchange at the interface between earth-moving machinery, as defined in ISO 6165, mobile road construction machinery, as defined in ISO 22242, and the worksite information systems. It focuses on data for management of a worksite and the assets specific to that worksite. This document includes: a)       methods of local position correction and localization, including standardization of RTK corrections; b)       method of implementation of a common design model; c)        types of data and methods of data exchange between servers. This includes application programming interfaces (APIs) to exchange data between servers regardless of vendor. These APIs focus on project data, as-built data, and production data. Field-equipment-to-server and machine-to-machine are not included. This document covers both hardware mounted on earth-moving equipment and field measurement equipment. This document does not define methods of on-machine data collection, on-machine communication protocol (e.g. CAN bus), wireless transmission of data to the vendor’s server, or wireless transmission of data directly between machines onsite. This document also does not include design software requirements or other areas related to building information management (BIM). Data formats and transfer methods from design software to the SMS are not in scope.
