Digital Platforms/Pilots Horizontal Activities a) Support pilot activities and knowledge transfer across different sectors: Coordination of the selected platform and pilot projects under the topics of this Focus Area, and where applicable with similar initiatives in Member States and Associated Countries, and with standardisation initiatives and support in ecosystem building to increase the impact of the overall set of projects. Exploitation of synergies between technology-based platform and pilot activities such as IoT and data value chains and the sector-specific platform and piloting projects of the Focus Area related to issues such as architecture, interoperability and standards approaches. Exchange on requirements for the development of common methodologies for design, testing and validation and for success and impact measurement. Furthermore, proposals need to promote the results obtained, support the enlargement of the ecosystems around the projects, facilitate the access for entrepreneurs/API developers/Makers and SMEs in general, and support the transfer of skills and know-how to industry.b) Legal, regulatory and security support: Further development and exploitation of security and privacy mechanisms towards best practices for digital platforms and pilots including contribution to pre-normative activities and to standardization; regulatory and legal support in relation to data ownership and protection, security, liability, across sector legislations. The corresponding activities will be developed and addressed in the pilots and consolidated at programme level under this horizontal support activity line.c) Preparation of a digital industrial platform for the construction sector: proposals should bring together relevant stakeholders and define a reference architecture for a digital industrial platform for the construction sector that increases productivity and optimises material usage in the construction sector, including for SMEs. It needs to take into account the recently developed framework with core indicators to assess the environmental performance of buildings, including circular economy aspects[[http://ec.europa.eu/environment/eussd/buildings.htm]]. Proposals should take stock of other ongoing initiatives, promote mutual learning and coordination, and identify knowledge and intervention gaps. Widespread use of Building Information Modelling and building passports will promote information sharing about different resources and their life cycles, re-use of materials, productive processes, including improved engineering, procurement and supply chain management and are therefore part of the scope.Proposals should address only one of the above-mentioned subtopics a), b), or c). The Commission considers that proposals requesting a contribution from the EU up to EUR 2 million for a) and EUR 1 million for each of b) and c) would allow above areas to be addressed appropriately. Nonetheless, this does not preclude submission and selection of proposals requesting other amounts. At least one coordination and support action is supported for each of the areas above. Coordination and Support activities are needed to support the operation of the pilot projects under the Platforms and Pilots topics in this Focus Area, and to support exploitation of the outcomes of these projects. These activities are expected to identify synergies among the pilot projects of the Focus Area, to promote cross-fertilisation, and to exchange best-practices and lessons learned. There is a need to increase coverage in technological, application, innovation, and geographic terms of these projects, as well as improve their engagement with relevant external stakeholders, and their links with regional/national and other European initiatives. In addition, coordination and support activities are needed to pave the way for future digital industrial platforms in another promising sector, the construction sector. There is major improvement potential in optimising resource use, environmental performance, health, comfort, and resilience to climate change. Tangible contributions from European key players to actively engage with the platform building process; Efficient information sharing across the programme stakeholders for horizontal issues of common interests; Maintaining and extending an active eco-system of relevant stakeholders, including start-ups and SMEs; Validation in usage context of usability, risk and security assessment and identification of gaps related to trust, security and privacy, respect for the scarcity and vulnerability of human attention, and liability and sustainability; Strengthening of the role of EU on the global scale, in particular in terms of standardisation activities and access to foreign markets; Increased prospects on productivity improvements in the construction sector, and on a contribution to a more sustainable construction sector.
