REAL-TIME, CONSTRUCT TO DESIGN SOLUTION
The GML – together with its Construct-to-Design Module – is a high-speed computing and rapid- visualisation technology, proven to significantly improve the efficiency and quality control of tunnel construction.
Used during various stages of the construction cycle, the system tracks and verifies as-built construction against the desired design in real-time.
This allows users to make calculated decisions in real time to increase efficiency, save time and cost, and reduce rework with every advancement.
Each highly precise image contains tens of millions of points, giving users high-resolution 3D information of the current construction against the desired design profile.
Areas of non-compliant construction can be detected and rectified immediately, reducing the need for labour-intensive, time-heavy, and costly rework.
The system provides live guidance during the shotcreting stage, allowing the operator to spray to the desired tunnel profile and reduce overspray.
The system has been proven to reduce shotcrete usage by over 20%. This decreases the associated time and cost of this operation, and the environmental impact of shotcrete manufacturing.
Users can also estimate the volume of shotcrete needed to reach the design profile, giving engineers control over the volume of shotcrete orders.
Providing construction guidance and instant rectification at every stage allows huge efficiency gains.
Together with the minimisation of rework, and continuous improvement with each advancement, the system allows for more efficient tunnelling.
The GML ensures every stage is built to the highest quality through its high-accuracy scan registration.
GML data can also be streamed to the engineers and managers at the surface in near real time. This expedites turnaround for QAQC checks and effective communications of as-built information amongst engineers and construction crews.
All data gathered by the system can be fully georeferenced. This allows users to export a georeferenced point cloud of a scan or specific highlighted areas.
The point cloud will import directly into the BIM model software, correlated to the exact location.
The GML uses proprietary compression techniques to optimise its data. Deformation data can be streamed to engineering and survey crews in the office to resolve time-critical bottlenecks.
Deformation data is compressed to 1/100th of its size, for fast streaming over even low bandwidth connections.
All scans are stored and managed automatically, with no manual intervention required by any user at any stage.
The database system manages data from multiple scanners across multiple sites concurrently and without difficulty, critical for BIM compliant scanning.
All GML scan data can be synchronised to a central server to ensure a single source of truth, with immediate availability to multiple concurrent users.
This allows them to access and view all the uploaded data from a single dashboard. Group permissions can also be set to control data access.
