5 JUNE 2018: For site engineer Abdulaziz Al Rowishad, working on one of the icons of the Riyadh Metro project is a way of life, but not one he takes for granted.
Joining Consolidated Contractors Company (CCC) on the Riyadh Metro in June 2015, he was assigned to Olaya Station, a key transfer station on Lines 1 and 2, as excavation works were in progress.
“The water table was the biggest challenge we faced,” Abdulaziz recalls. “We were excavating the propping in parallel to protect the station from water.”
“We also dug to 20m and worked until the tunnel boring machine [TBM] passed under the Line 2. We then dug the TBM rings, excavating to 30m, the lowest level on Line 1.”
Abdulaziz moved on to Line 2 where, as site engineer, he was part of the ‘Cut & Cover’ excavation team supervising the subcontractor at Olaya Station.
“I supervise the work from Line 2 level up deep underground up to ground level. That’s five levels in total (Line 1, Line 2, Concourse, Mezzanine and Ground).”
It is a busy, bustling work environment deep under city streets. Olaya Station has some 700 workers operating two round-the-clock shifts.Subscribe to continue reading...
