Improvement of Al Shindagha Corridor-Sana Junction Project R-1013/1

Improvement of Al Shindagha Corridor-Sana Junction Project R-1013/1

To mitigate the foreseen increase of congestion at the Sana junction, the RTA decided for grade separation at the junction. It comprises of two parallel underpasses along Shiekh Rashid Road and two parallel bridges with approach ramps along the Sheikh Khalifa Bin Zayed Street.

The underpass is in the close vicinity of the Dubai Metro Red Line pier RPN 194 (at ~ 30 m distance) and therefore is classified as a restricted activity within the Railway Protection Zone 1 for constructing a viaduct or bridge type A. To ensure safety and durability of the existing metro infrastructure, monitoring of the response of ground, groundwater and existing pier piles became an important part of the task. The automatic online monitoring method was adopted to ensure safety of the existing running metro.

Encardio-rite was awarded the complete sub-contract for monitoring work. Scope of work included conducting a pre-construction (dilapidation) condition survey of metro piers and viaduct, supply, installation, manual monitoring & surveying and online monitoring of sensors & geodetic points (surveying) of critical parameters and areas.
