1915Çanakkale Bridge Opened 18 Months Ahead of Schedule
The 1915Çanakkale Bridge was officially opened in a ceremony attended by Turkish President Recep Tayyip Erdoğan on Friday 18 March 2022.
Taking it’s place as the world’s longest mid-span and highest tower suspension bridge, the 1915Çanakkale Bridge was completed 18-months ahead of schedule, in part due to the innovative heavy lifting crane solution developed by Australian craneage experts, Marr Contracting.
Soon after the Turkish Ministry of Infrastructure and Transport General Directorate of Motorways appointed the Turkish-Korean joint venture partners – DL E&C–Limak–SK ecoplant–Yapi Merkezi (DLSY) – as the construction partners on the project in 2017, DLSY contacted Marr Contracting for a craneage solution to match how they wanted to construct the project.
One of multiple subcontractors from a global team of companies engaged to work on the project, Marr’s scope of works on the construction of the 318-metre high bridge towers included engineering the heavy lift crane solution involving its integration into the temporary and permanent works, the supply of two M2480D cranes (including installation, climbing, dismantle and maintenance), and crane operation.
According to Marr Contracting Managing Director, Simon Marr, early engagement with the DLSY during the front-end engineering stage of the project was key to the project’s success and the constructor’s ability to align a crane solution with their construction methodology.
Marr’s innovative approach – using two of the world’s largest capacity heavy lift luffing tower cranes, (the 330-tonne capacity M2480D) – allowed for pre-fabricated, modularised panels weighing up to 160 tonnes to be manufactured off site, transported to site to be lifted in one piece.
Marr’s 18-month engagement on the project between 2019 and 2021, saw two world first engineering feats – the placement of the two M2480Ds in a single lift operation 1km offshore in the Canakkale Strait and the heaviest crane lift at height during the positioning of the upper cross beams on the bridge towers – as well as numerous other innovations to integrate the heavy lift tower crane engineering into the project and minimise critical path impact to the construction schedule.
