12 concrete underground tanks are currently being built, each of which is 110 by 110 meters, as large as two football fields. A total of 13.2 million barrels of oil can be stored here after completion. 150,000 cubic meters of concrete total - equivalent to the contents of more than 60 Olympic swimming pools. PERI was extensively involved from early design stages up to completion. The OTMS tank structures called for a unique design to construct the columns, walls and slabs. Sloping slabs on top of 17 columns, as well as the sloping floors presented design challenges for the design of a suspended support system for the slabs
Main challenge: extremely short cycle time for the 17m high slab formwork of 6 days for a 110 x 110 x 8m section, wall formwork with steel face, 17m high columns in one pour.
