At LNG Tanks, Chhara, the main works involved the construction of two LNG storage tanks (outer diameter 89.6 m and inner diameter 88 m). The tank construction included the construction of a prestressed concrete (PC) wall 37.36 m high, to be built in 10 lifts. The team was able to reduce the PC wall construction cycle time for Tank 2 by 25 percent (nine days) compared to Tank 1 by applying LPS, 5S and waste disposal. PC wall activities involve multiple teams working together: rebar attachment, H-beams for thrust ring support, prestress channel laying, installation of VTL and HZT embedded plates, installation of formwork, etc.
Minimizing transport and multiple handling by stacking rebar, shackles, vertical and horizontal inserts close to the corresponding section of the PC wall
Standardized work order and coordination meetings at the start of the day to minimize cross-team interference Analysis of variance in planned versus actual progress to identify root causes of delay
Design changes to TCP plate joints to minimize post-processing and improve alignment speed.
