    Look-ahead planning has a key role for construction management as an intermediary between master schedules and site production. Its effective implementation can improve construction management and production control for a specific time period, while considering site performance, work sequencing, and matching tasks to resources. However, it remains a highly manual process, it is not integrated with Building Information Modeling (BIM), and it is hard to consider process alternatives at this level. In addition, there is a gap between Look-ahead Scheduling (LAS) process and site production in terms of information such as design changes, site progress, and resources availability. BIM and simulation have potential for improving look-ahead planning processes. This thesis presents techniques to make look-ahead scheduling process work within a structured BIM and resource-integrated simulation approach. It integrates and analyzes necessary information from planning and site using BIM. This information includes a coding structure for BIM entities, tasks and work sequence for scopes of work, available resource data, construction constraints and site progress information are integrated with BIM. The necessary information is integrated in a unified platform for look-ahead planning using an existing simulation tool called GSimX for analysis. The building test case presented in this thesis demonstrates the approach with simulation support to generalize its use within lean construction context. The results show alternatives of look-ahead schedule considering the crews and equipment status, site progress and constraints. Results also demonstrate updating of master schedules. As a result, planners will be able to effectively generate look-ahead tasks and match them with resources all within a BIM environment using simulation.
