Assessing the performance of the BIM implementation process: a case study
The article proposes a system of indicators to measure the performance of BIM (Building Information Modelling) projects. Proposed indicators divided into two groups: quantitative (cost and time related numerical values) and qualitative (verbally expressed measures recalculated to scores according to proposed four-point rating scale). The metrics include the calculation of time and cost variations, the assessment of the organizational scale of BIM deployment, BIM competency granularity level, BIM capability level, BIM maturity level. In the case study, the proposed indicators applied for the evaluation of the results of the real construction project. The limitations and difficulties faced up during the project implementation discussed, and the benefits of the application of the BIM methodology revealed. The application of the proposed methodology is useful in assessing, at which level the BIM applied in construction projects and measuring the progress towards achieving project goals. The proposed methodology may also be useful for constant monitoring of the BIM implementation in construction projects.
