Project Description

Detail Design Services for revision in alignment and design of cross passages , Rescue Shafts as well as revalidation of works previously done by ex-DDC of Contractor.

Special Features

Mid Shaft “Gurudwara shaft wasn’t part of the original construction plan, but had to be constructed as two TBMs commissioned from Azadpur station towards Majlis Park, tasked with tunneling 1100m, got stuck mid-way in 2014. So , therefore 4 TBM’s has to be rescued from this shaft. As the mid shaft had to built with close proximity to the residential area, therefore special precautions had to be ensured in design keeping in view the safety of residential buildings.
