Abstract ABSTRACT Structures are suffered from continuous ageing effects. Deterioration or degradation is inevitable process for all Structure elements. Reliable inspection and monitoring tools are therefore an increasing demand. The diagnosis and the evaluation of current conditions and residual service life of existing structures are key aspects of concrete structure management. Using Building information modeling (BIM) is very useful to facilitate the condition assessment of the Structure and record all repair works that have taken place during its life cycle. The assets owners can receive the benefit of using BIM by incorporating the principles of BIM into the operation and repair action of Structures. The main focus is on the integration of repair data by using building information modeling (BIM) to facilitate efficient inspection planning and to improve the condition assessment process for Structure elements. This research presents a framework based on BIM for Structures condition assessment. The framework consists of three models: Condition Assessment Model, Deterioration Predictive Model and Repair selection Model. The condition assessment accurately evaluates the condition of Structure elements, depending on the current condition assessment; the proposed deterioration model predicts the future deterioration of the elements for each year and overall Structure condition during its life cycle by using a Marcov Chain model. As follows, the present condition and the future deteriorations are monitored by the proposed framework and used to get the best repair actions within available budget. To verify and test the suggested methodology, a real model (case study) was chosen in order to apply the proposed method. The model is a building consisting of a ground and four typical floors. After number of years of its construction an assessment committee was formed to evaluate the current structural performance and predict its future deterioration to decide the best repair actions within available budget. |
