The Core of Eden: A Case Study on Model-Based Collaboration for Integrated Project Delivery

The paper examines the model-based design processes in the Eden Core project in Cornwall, U.K., concentrating on key aspects of the collaboration between the architect, consultants, design-build general contractor, and fabricator, within the specific context of an innovative biomimetic design which integrates sustainability and a biologically inspired complex geometric roof structure. It is analyzed how 3D models support building simulation processes and how various computer modeling techniques are used to resolve the complex geometric issues of the timber grid-shell roof fabrication design. The paper aims to contribute to the understanding of model-based practices in the design of sustainable and complex-shaped buildings, and adds to the growing body of descriptive literature on integrated practice. The study provides (1) a 3D modeling process map which describes how modeling supports collaboration and how it integrates into traditional design processes, and concludes with (2) alternative approaches to overcome the challenges of model-based collaboration approaches.
