Construction Jeddah Tower

construction site seen plane, april 2016

while official construction estimate 5 years , 3 months (63 months), others calculate take longer, on 7 years, based on duration of burj khalifa s construction, on 6 years (with of cqc department).

geotechnical investigation (soil testing) took place in 2008. work on foundation scheduled begin towards end of 2012. however, statements construction begin have been made since 2008, have been postponed each time. in august 2011, start of construction slated no later december, saying immediately, , construction imminent. meant tower expected completed in 2017, though @ time possible still have been completed date media continued publish, prior estimate of late 2016. if construction had begun promptly , went smoothly late 2016 completion achieved?

designs foundation in place august 2011 , contract piling being tendered. on 16 august 2011, langan international officially announced involvement , foundation , piling had uniquely designed overcome subsurface issues such soft bedrock , porous coral rock, not support skyscraper without settling. foundation similar of burj khalifa, larger; expected average around 4.5 m (15 ft) deep concrete pad of area around 7,500 m (81,000 sq ft). concrete have have low permeability keep out corrosive salt water red sea. depth , size considered indicator of tower s final height be. piles 200 m (660 ft) deep , pad on 90 m (300 ft) across, yet still building, weigh on 900,000 tonnes (890,000 long tons; 990,000 short tons), expected settle. idea settles evenly enough building doesn t tip or put undue stress on superstructure. computer modeling programs performed tests @ site confirm foundation design work. later design foundation, constructed bauer in 2013, calls 270 bored piles 110 m (360 ft) deep have installed difficult ground conditions. materials needed structure 500,000 m (18,000,000 cu ft) of concrete , 80,000 t (79,000 long tons; 88,000 short tons) of steel.

construction of building rely on cutting-edge technology, including high-strength reinforced concrete , pumps used elevate record heights, similar used during burj khalifa s construction. bob sinn, principal of thornton tomasetti states, “concrete quality getting better , better, pumping technology. there have been strong advances in reinforced concrete on last 20 years. continued, [jeddah] tower feasible. s not structural challenge.
