Cost estimate accuracy has a severe effect on the expected profit of a construction contractor. Although Building Information Modelling (BIM) had a significant impact in that domain, it needs some time to create and finish a model. Creating a BIM model with the required Level of Details (LOD) can give accurate cost estimates and save time. This paper tries to find the minor details of a BIM model, which offers a sufficient cost estimate accuracy through residential buildings projects stages. Reaching the appropriate level of details is done by revising literature and conducting a questionnaire survey that was distributed among a sample of expert BIM engineers in Egypt. Finally, a case study for a residential building project in Egypt is introduced. Two BIM models were implemented to find the appropriate level of details that give needed accuracy with the least effort during the design project stages.
