Multiplex are the main contractors on this project who in turn have contracted the Zutec platform for several of their processes.  The Snagging & Defect Management tool was used as the main Quality Assurance collaboration platform for the project. Multiplex used this to capture all tasks such as snags, defects, observations, incomplete works, outstanding works and clean up notices and raise them against the responsible subcontractors. The Client Representatives, Multiplex and all subcontractors use this tool to collaborate and resolve all issues captured onsite. The Task Management tool also provided detailed insights and analytics through the embedded and interactive dashboarding on the Zutec Platform.

The Zutec Construction Progress Tracker was used to capture every Fit-Out Construction Activity in the building. All of the supply chain used the tool to record their Construction activity progress room by room and also attach corresponding Quality Assurance documentation and As-Built dates. This granted Multiplex a real-time insight into Construction Progress vs Plan and Quality Assurance through the in-depth dashboard reporting from the Zutec Platform.

The Site Diary tool was used by all onsite staff to record the daily site activities and observations such as subcontractor labour count, environmental observations, delays, progress etc.

As with any multi million pound development, project handover is a key component in completion and Zutec’s Digital Operations & Maintenance Manuals were used as a collaboration tool for all subcontractors to upload all of the required handover information which is essential for a smooth handover and successful running of the building post-handover. All information uploaded was brought through a workflow and validated by the various certifiers. The Zutec Digital O&M tool provided real time reports on the handover documentation progress which enabled Multiplex to effectively track and capture all the required documentation in time for handover.
