The total building area of No. 1 Blay Street spans approximately 42,000 square meters across 28 floors. About 40% of the structural materials consist of renewable concrete, while over 90% of the steel bars contain more than half renewable materials. The project also incorporates renewable wood, solar cooling systems, sewage treatment, rainwater collection, and wastewater treatment systems.
The design features a unique naturally ventilated atrium combined with a double-layer curtain wall system on the exterior. This not only enhances the building’s aesthetic appeal but also significantly reduces its energy consumption.
No. 1 Blay Street serves as a prime example of BIM technology applied throughout the project lifecycle. From initial planning and design to sustainability analysis, construction, and property management, all stakeholders consistently used BIM to overcome traditional workflow challenges. BIM technology also played a critical role in training construction and management personnel who were initially unfamiliar with this approach.
BIM technology also defined the project requirements, standards, protocols, and development plans through related guidance documents. These clearly outlined the objectives for project management, setting the tasks and challenges to be addressed.
During construction, conflicts between building structures and pipelines arose, mainly due to coordination gaps within the building information model and differing interpretations among participants. To address this, a BIM collaborative platform was established, allowing all parties to access real-time construction progress and avoid misinformation or delays.
Regular project summary reports were promptly shared with representatives to prepare for upcoming coordination meetings. This collaborative BIM approach enabled team members to record their progress in a shared database and document meeting outcomes throughout the project. Such detailed records helped prevent disputes and errors, providing reliable resources for future claims or litigation.
The BIM practice at No. 1 Blay Street evolved from planning through design, construction, and project delivery. The BIM information model and associated data became increasingly refined and integrated into the final comprehensive BIM model.
This final model consolidates all construction information, serving as a complete record of the project’s implementation and forming the foundation for ongoing operations and maintenance of the building. The comprehensive BIM database has become an essential tool for building management, coordinating various information systems, improving operational efficiency, and demonstrating BIM’s value throughout the building’s lifecycle.
All parties involved highly praised the BIM application in the No. 1 Blay Street project. The final BIM model integrates data from 32 companies involved in construction. Grocon Construction Company, the general contractor, developed building information models for over 30 related disciplines. This approach significantly reduced on-site conflicts, enhanced construction quality, and saved considerable coordination time.
