Value : AED 412 Million
Duration : December 2005 – August 2009

THE CHALLENGE
Every infrastructure project planned in the middle of an active city is poised to encounter and mitigate various risks, mostly in relation to existing underground utilities. The Dubai Metro project was not an exception.
The detection, protection and eventually the diversion of existing utilities was a challenging and critical task for NBHH especially where the underground metro stations, cut and cover tunnels, or piling foundations had to be constructed. The latter construction activities had to be carried out while minimizing the disturbance to the end users and Dubai residents.
In that respect, our company managed to overcome all the different challenges, whether foreseen or unforeseen, for a project duration that spanned for three and half years.
