BIM-BASED HYBRID SCHEDULING FOR HIGH-RISE BUILDINGS
The adoption of Building Information Modeling (BIM) in construction has increased over the past decade, becoming standard in high-rise projects that are resource-intensive and schedule-sensitive. BIM enhances project management by integrating design and detailed work packages, facilitating effective resource allocation and information retrieval throughout the project lifecycle. However, existing BIM-based scheduling approaches often struggle with heavy procedures and poor integration. This paper introduces a BIM-based dynamic hybrid scheduling system that optimizes construction time and cash flow. The model connects the BIM model with scheduling software, utilizing the Work Breakdown Structure (WBS) to estimate the duration of construction activities and facilitate schedule adjustments. Key objectives embrace developing a scheduling database and a computerized hybrid scheduling system. The analytical model consists of the following main steps: establishing a database of construction work inputs and activity dependencies, preparing the model for scheduling, partitioning the building model into typical work sections, grouping elements into activities, creating a schedule database, scheduling in dedicated software, and conducting a BIM-based visual simulation of construction activities. This hybrid model seeks to enhance design quality and provide dynamic scheduling and alternative construction methods, including material and equipment orders, manpower, costs, and expected durations. The prototype has simplified and improved the scheduling process, making it more accessible to stakeholders while allowing for feasibility assessments and comparisons of construction and scheduling alternatives, considering time and resource constraints. Validation involved scheduling a 15-story residential building in Pardes Hanna, Israel, demonstrating the method's feasibility, efficiency, and effectiveness. The proposed method allows for dynamic real-time management, scheduling, and procurement. It can be integrated into an Enterprise Resource Planning (ERP) system, integrating enhanced time, cash flow, and resource allocation planning. The model contributes to state-of-the-art hybrid scheduling with integrated construction methods, scheduling, resource allocation, and costs.
