Abstract:The construction sector is digitizing. The most important factor in this is BIM or Building Information Modeling. While BIM is already used quite widely among civil engineering firms, the technology is still constantly developing and there are lots of opportunities for BIM to become an even greater part of the built environment. With climate change being a serious problem these days, there is an increasing demand for building more sustainably, and calculating the environmental impact of construction projects, for example with MKI values. This report focuses on how integrating BIM technology with LCA and MKI can aid these calculations and allow for more sustainable design processes. In 2020, Maarten van Eldik already developed a BIM-MKI tool for this purpose (Van Eldik, Vahdatikhaki, dos Santos, Visser, & Doree, 2020). However, three years later, the tool is still not used that much in practice, despite receiving (almost) exclusively positive feedback from experts at Witteveen + Bos after its initial development. This raises the question: why? Why is it that this tool is not used in most projects despite having obvious benefits to manual calculations? This report focuses precisely on that question and draws a roadmap for Witteveen + Bos to follow for integrating BIM and MKI via this tool for all projects (eventually). To do this, three research questions have been drawn up: (1) What barriers are encountered when integrating BIM and LCA? (2) How can these barriers be prioritized? (3) What would be a logical roadmap for integrating BIM and MKI? From interviews, it became clear that MKI calculations are currently mostly performed after the design process, when a final design is made, this makes MKI mostly an end product. Ideally, MKI values would be calculated during the design process, so that adjustments and design choices can be made based on reducing the environmental impact of the design, rather than evaluating the environmental impact of the design only after the design cannot be adjusted anymore. Ideally, Witteveen + Bos would design several alternatives of a design and assess them with a tradeoff matrix in which MKI is included as a criterion, among other criteria such as structural safety and cost estimation. Twelve barriers were identified which are needed to be overcome for the integration of BIM and MKI (on a large scale). Using a survey, these barriers were analyzed and prioritized. Respondents created two ranked lists of all barriers, the first being ranked from most impactful to least impactful, the second being ranked from easiest to overcome to hardest to overcome. Seven respondents have filled out the survey, after which the barriers were analysed based on these two attributes. From the analysis, it was concluded that the barriers with the highest priority to overcome are: Setting up the MKI mapping table (via DuboCalc) is not yet automated enough to make it standard for every project, the tool is not yet user-friendly enough for people who did not develop it, a reasonable degree of MKI knowledge is required to use the tool, there is too little guidance at the beginning of projects towards the use of the MKI tool during the design process due to the lack of a standard process, and there is little knowledge about the possibilities of BIM-MKI integration among clients. From these results, a roadmap is drawn. The roadmap is a two-year plan on how Witteveen + Bos can develop the BIM-MKI integration technology by first creating an MVP version of the tool and then scaling up the product by developing the technology further but also marketing it to clients.
