Current design practice and construction delivery have traditionally suffered from poor coordination and indentation in the way that multi-disciplinary team members manage and replace project lifecycle information. However, Information Communication and Technology (ICT) consented collaboration through building information modeling (BIM) particularly the 3D modeling aspect has the potentials to innovate, transform and foster the process of information exchange and cross-disciplinary collaboration. Regardless, exploiting the full potential of BIM requires tools, protocols, and open standards for collaborative working. The cloud-based shared workspace also called a Common Data Environment (CDE) is required to facilitate seamless data transfer and sharing of data across the multi-stakeholder environment.
Causes of Clashes :
- Use a low level of detail
- Design uncertainty/use of Placeholders
- Accuracy versus deadline
- 3D model objects exceeding the allowable clearance
- Designers working in isolation from each other
- Design complexity
- Insufficient time
- Use of 2D instead of 3D models
- Design errors
- Use of different file formats
Clash Avoidance Strategies :
- Impose BIM in traditional procurement
- Integrating Engineering, Construction, and Procurement
- Improvement in software clash detection algorithms.
- Co-creation among designers in a shared workspace.
- Designers are working with more data provided by other senior consultants.
- Designers being more accurate with their model output
- Design coordination in a typical data environment (CDE)
- Shared situational awareness
