E Netz S Dhessen AG Tender

Contract notice: Delivery of environmental sensors, commissioning, data provision in a cloud A network of environmental sensors (official measuring points of the HLNUG, own environmental sensors and sensors of Deutsche Telekom AG) is in field use in the science city Darmstadt. Regardless of the procurement in question, these are connected to a technical platform for evaluating the data. As part of the DAnalytics project, it is planned to expand the existing urban environmental sensor network from 16 to a total of 41 measuring points with a total of 44 sensors of different equipment in order to obtain an even more detailed insight into the development of air pollution and dust emissions in the urban area. 4 sensors are installed at a common location in order to be able to use their comparative data for plausibility checks and validation of the sensor data in a rolling exchange process. The 16 existing sensors will be upgraded or replaced, depending on the options and the bidder's own selection, the remaining 28 sensors are to be delivered with different equipment. In addition to the sensors, the bidder must also deliver the components for the power supply at the 41 locations and the cellular communication to the bidder's background system for the 44 sensors for all locations. The bidder's background system is to be implemented on the one hand in a cloud-based solution and on the other hand, all data from all of the client's sensors must be made available via the MQTT (Message Queuing Telemetry Transport) messaging protocol. The sensors act as clients and send the respective data to a server (MQTT broker) made available on site by the Mobility Office of the City of Science Darmstadt. The services of the contractor are limited to the delivery of the sensors and the background system as well as their commissioning. The assembly services for the installation of the components on site (assembly on light masts) are provided by a representative of the Mobility Office of the City of Science Darmstadt; the contractor must provide training for the assembly staff for this purpose. The contractor of the present tendering process is expected to deliver the sensors, integrate the data from all environmental sensors (inventory and expansion) in a common, congruent database, quality assurance of the components during operation and the maintenance of the cloud service and the software of the environmental sensor network. In addition to the investment costs, the contractor must also state the service and operating costs for the overall system.
