Description
To address construction challenges, Kajima Corporation has implemented "Proactive Design," an innovative approach integrating detailed construction knowledge from the earliest design stages. This method fundamentally prevents issues related to quality, inconsistencies, cost overruns, and rework. For instance, after Phase 1, condensation issues arose only on the north façade, despite identical floor plans. In Phase 2, we used its integrated design-build capabilities to resolve this issue through early-stage simulations. A LOD 500 model is prepared at the commencement of construction, enabling BIM-based inspections 365 days earlier than standard, thereby mitigating postconstruction risks. During construction, Digital Workplaces ensure real-time consistency. Furthermore, Kajima promotes modularization at the design stage, involving engineers, subcontractors, and fabricators in a seamless integrated model. This approach aims to elevate industry standards and drive progress toward a sustainable future.
Key Learnings
- Analyze issues in existing buildings and conduct simulations for new buildings to learn methods for "quality enhancement."
- Learn about "zero rework" through detailed model building and unitization of exterior and equipment during the design phase.
- Learn how to use XR to visualize and resolve issues early, and learn methods for effective communication with clients.
- Learn the method of developing a construction integration model with 60+ partner companies from the early stages of design.
