Microservice-Based Middleware for a Digital Twin of Equipment-Intensive Construction Processes

Following the example set by Industry 4.0, digitization is being proven as a vital tool in equipment-intensive construction processes. Telematics data from equipment is sent to platforms. The profitable use of this data is part of today's research regarding digital twins. This paper shows the conformity to Industry 4.0 terminology and digital twin components in construction. It reveals the need for data transformation and integration to cope with the diversity of equipment fleets. Thus, this paper introduces middleware systems based on different microservices, each with a different functionality, and shows their implementation at the special foundation engineering project.
