ALEC has started its two-week, seven-phase schedule to install ‘The Link’, an 8,500-tonne steel bridge. included two towers standing at 300 and 235 meters respectively, The Link will become the world’s largest cantilevered building, connecting the two buildings at a height of 105 meters, while providing panoramic views across the city.
As a process, the difficulty of the engineering behind the lift is only equaled by the design of the cantilever itself. included seven steel modules, The Link will be lifted in one piece, using a series of heavy-duty jacks capable of generating up to 6,600kN of force from 12 lifting points.
In the first phase, which was completed on 18 August, the crowd was elevated just 100m over a 24-hour period – after monitoring its behavior for nine hours, engineers removed the temporary steel fittings before cutting the shoes and lifting the structure a further meter over the duration of 7 hours.
In the third phase, the team will install wind bracings to the side of the concourse in order to protect the lift from any adverse season, while a 300point survey will be operated to secure the integrity of the system.
After a final phase of superficial improvements, the main lift is scheduled to take place on 31 August and comprise a 72 hours road closure as the huge concourse is elevated to its final position. Once in place, The Link will be welded and tested, before the jacks allow to leave and the load transferred to the towers.
