Diera is one of the oldest communities in Dubai, sustaining on the front of the famous Dubai Creek. With its rich culture and tradition, the Diera Community is one of the most important economic hubs in the region.
The Deira Waterfront Development is strategically placed in the northern area of the Deira District, right across the street where the old Souqs and the Dubai Creek is located. It is planned to ensure the natural growth of the city, driving economic success and vitality of the area. Regenerating one of the oldest communities of the city will not only preserve the unique cultural values but will be extremely crucial for the city’s economic success.
The Deira Waterfront Development Project is in close proximity to the central destination and aims to have several fun components like leisure facilities, parks, and plazas, bicycle routes, transportation hubs along with retail facilities. It also involves the construction of several new plazas, mixed-use buildings, and green open spaces.
Apart from the new construction, the existing shops, commercial zones, parking, hotels, etc will also be improved to blend with the description of mixed-use development. The intention is to have a unique and beautiful seafront.
The Waterfront Project allows the Diera community to creatively and intelligently to blend the past, present, and future while preserving the heritage and culture.
Deira Waterfront Development – Plot 13
Phase 1 of the Deira Waterfront Project involved the development of 30 plots along the waterfront, with each having its set of developments and designs.
One such plot, Plot-13 is situated in the north area of Dubai in the Deira District. The Mixed Used Development at Plot 13 involved the construction of a two-level basement (approximately 10 m deep excavation) between the Al Shindagha tunnel and Dubai Metro Green Line tunnel.
The shoring work was in close vicinity to both the tunnels, with the nearest edge only 10m from the Green Line Tunnel and 15m from the existing Al Shindagha Road tunnel. The involvement of heavy construction activities so near to the tunnels made it crucial and necessary to monitor the areas.
Let’s take a look at the proposed monitoring solution by Encardio-rite, followed by the instrumentation of the site.
Monitoring Solution – Deira Waterfront Development
With a considerable risk involved due to the existing tunnels, the main intention of the instrumentation and monitoring procedure was to systematically recognise any design risks caused by the construction. For complete safety, it was crucial to monitor the response of ground, groundwater and viaduct foundations during the construction period.
The Turnkey Services Included:
- Supply and Installation of Geotechnical and Geodetic Instruments
- Manual and Automatic Surveying
- Online Monitoring of crucial parameters and areas
- Manual Monitoring of Installed Geotechnical Instruments
- Daily & weekly reporting with evaluation & interpretations
- Pre-construction condition monitoring of both the tunnels
Instrumentation – Deira Waterfront Development
Encardio-rite provided instrumentation and monitoring service for the ongoing excavation work as well as for the existing metro and road runnels.
Let’s take a look at the geotechnical sensors and instruments used during the process.
Instrumentation during Excavation and Ground Monitoring
The Inclinometer was employed to monitor the lateral movement and movement of soil between the construction area and tunnel.
- In-place Inclinometer
In-place Inclinometers were used to observe the lateral movement along with the deformation of earthworks and shoring wall.
- Standpipe Piezometer
The Piezometer was involved in the monitoring of water level/drawdown during the construction period.
- Ground Settlement Point
They were used to monitor soil settlement and deformation of the ground surface.
- Anchor Load Cell
Load Cells were utilised for the monitoring of force in the ground anchor.
Instrumentation & Monitoring of the Existing Metro, Road Tunnels, and Rail Tracks
- Strain Gage
They were used to monitor the stress in tunnels and also to alter the in-strain of tunnel lining. This was done to hoop compression and bending moments.
- Tape Extensometer
These were employed in the Shindagha tunnel to monitor convergence.
- Borehole Extensometer
The Automatic Extensometer was designed and installed to monitor the deformation of the existing line.
- Magnetic Extensometer
These were involved in the monitoring of subsurface settlement.
- Beam Sensor/Tiltmeter
These sensors were employed for monitoring differential movement and tilting in tunnels, and the variation in diameter under unbalanced loading.
- Beam Sensor
Beam Sensors were used to keep an eye on the movement of the trackbed.
- Tri-axial Vibration Sensor
They were involved in the monitoring of the impact of piling operations on the tunnel.
- Prism Target
Prism Target was installed for the monitoring of displacement in the tunnel.
- Crack Meter
To monitor change in the width of existing cracks & joints within the tunnel
The sensor installation in the existing metro tunnel was a crucial and time-constrained task as the metro trains only allowed 2 hours at midnight for the installation. For critical geotechnical sensors, online monitoring was carried on with the help of our range of advanced automatic data loggers and data acquisition systems. For online monitoring of geodetic points, Automatic Total Stations (ATS) with complex control boxes were used.
The Monitored and Recorded Data was made available through our web-based Data Management System to the concerned parties, making it accessible through their desktops. Monitoring Reports were formulated and submitted for the geotechnical and geodetic monitoring data on a daily and weekly basis. Monitoring reports also included the interpretations of variations observed in instrument data with respect to the construction progress in the respective area.
This brings us to the end of our Case Study on Deira Waterfront Development. Hope you found it interesting.
