Our Partner, VTT, Finland

Wed, 18 March 2020
VTT Technical Research Centre of Finland Ltd is a state owned and controlled non-profit limited liability company operating under the Finnish Ministry of Employment and the Economy. VTT is a research and technology organisation (RTO) whose activities are focused on three areas: Knowledge intensive products and services, Smart industry and energy systems, and Solutions for natural resources and environment. VTT is impact-driven and takes advantage from its wide multitechnological knowledge base to strengthen Finnish and European industrial competitiveness. VTT has a staff of 2054, and net turnover in 2018 was 159,7M€. Over the years, VTT has gained vast experience from participation and coordination of numerous European projects.

I am Teemu Vesanen, a senior scientist working with information systems in the built environment. In my research and development activities, I focus on energy and indoor environment quality. In the BIM4EEB project, I am a leader of a work package focusing on digital tools for fast track renovation operations. In addition to that, I am also leading two tasks in another work package that develops and tests a decision support tool for BIM assisted energy refurbishment. Finally, I am also leading the VTT team in the project: Markku Kiviniemi (leading tasks for renovation operations and pilot), Teemu Mätäsniemi (ontologies and software implementation), Rita Lavikka (renovation operations), Jari Shemeikka (energy tool), Vu Hoang Nam (renovation operations and software implementation), Tiina Vainio-Kaila (product data and logbooks), Jouko Piippo (energy tool and software implementation) and Ala Hasan (support in publications).

The starting point for the BIM4EEB project has been to increase the use of building information modelling (BIM) in the renovation business. The project efforts are focused on the future renovation business as the currently renovated buildings do not usually have BIM.

Digital tools for fast track renovation operations denote BIM-enabled methods and tools in operations management at site and with prefabrication. They enhance the current construction planning and tracking methods with a shared approach and combine the digital plans and progress tracking of all project stakeholders. The work package aims to create a system that will provide 24/7 situational awareness of the statuses of the renovation activities. The reliable progress data will be available also to the clients and occupants with right timed guidance and safety instructions.

The BIM-based design allows managing the compatibility and tolerances between design disciplines and adapting those with mapped geometry of the building. This accurate data enables the prefabrication and preassembling of structural and system components. We will develop two best practice examples of how to utilize prefabrication with BIM in renovation projects for improving energy efficiency through prefabricated insulation element and exhaust air heat pump.

The particular focus in the work package is to shorten the duration of the renovation and disturbance to occupants by speeding up the installation tasks. These goals are enabled with the improved situational awareness, which makes progress transparent and allows scheduling the site activities with shorter lead times. It will shorten the total construction duration while granting the immediate control of possible deviations in implementation.

The results will be demonstrated with a software tool for task management and communication. Improved working methods and processes will be described in reports that will present the tool, required online digital logbook and prefabrication processes. The reports will be confidential for consortium members. Anyone interested in the results is welcomed to contact me or another member in the consortium. We are happy and proud to share the information within limits specified in the consortium.
