LOTTE Engineering & Construction wins Works Award for ‘Lotte Castle De Mer’... connects two towers 170m above ground

[Financial News] LOTTE Engineering & Construction Co., Ltd. received the Korea Concrete Institute Works Award for its high-rise construction technology at ‘Lotte Castle De Mer’ in Busan. The award recognized its achievement in building challenging structures, including a sky bridge connecting two towers 170m above ground.
LOTTE Engineering & Construction Co., Ltd. said on the 12th that it had received the Works Award at the Korea Concrete Institute’s fall academic conference, held on the 5th at Alpensia Resort in Pyeongchang, Gangwon Province. In its 35th edition, the award is presented to organizations and individuals that design or build concrete structures with high standards of design and construction.
Lotte Castle De Mer is a mixed-use complex in the Busan North Port redevelopment area in Choryang-dong, Dong District, Busan, with five basement levels and 59 floors above ground, reaching a maximum height of 213m. Located on the waterfront next to the Busan Port International Passenger Terminal, it was designed by Junglim Architecture and built by LOTTE Engineering & Construction Co., Ltd.
The key technology was the ‘lift-up’ method used to install the sky bridge on the 51st floor above ground. The structure was first assembled at ground level, then hoisted with strand jacks—heavy-lifting equipment—and joined to the two towers.
The work required connecting the structures 170m above ground while managing construction tolerances between the two towers. From the early stages of construction, LOTTE Engineering & Construction Co., Ltd. operated a dedicated technical management team that included members from its housing and building construction division, design research institute, and technology research institute. In October last year, high-rise experts from Korea, China, and Japan visited the site to observe the construction process.
The institute said the project used advanced construction techniques to build a high-rise structure and sky bridge that harmonize with the waterfront landscape, enhancing the scenic value of the North Port skyline and its concrete buildings.
LOTTE Engineering & Construction Co., Ltd. had previously won the same award for three consecutive years, from 2019 to 2021, for the Incheon Port New International Passenger Terminal, Sejong Raycastle G&R Clubhouse, and LOTTE Academy Osan Campus.
Seok Won-gyun, head of LOTTE Engineering & Construction Co., Ltd.’s Technology Research Institute, said, “We will continue to focus our capabilities on developing high-rise and high-strength concrete technologies, as well as carbon-reducing, eco-friendly material technologies, to lead change in the rapidly evolving construction environment.”
