Multidisciplinary company BESIX has announced that the POST Rotterdam project in the Netherlands, a development that merges the conservation of a historic site with contemporary design, has achieved a pivotal construction phase with its topping out at 155m.

The topping-out ceremony brought together partners and the project team, highlighting the culmination of meticulous planning, technical expertise, and the efforts of many professionals and site workers, stated the company.

POST Rotterdam is a revamp of a historic post office in the centre of the city.

BESIX COO construction Jan Van Steirteghem said: “Bringing the core to its final height of 155m required exceptional coordination, engineering, and execution. Thanks to the use of hydraulic climbing formwork this was both efficient and precise. The result is clearly visible in the Rotterdam skyline. The core itself houses critical elements such as stairwells, lift shafts, and structural stability walls, making it the backbone of the tower.

“Together with our partner Rizzani de Eccher, we are proud of what has been accomplished here and of our continued contribution to the evolution of this city.”

Designed by US-based architect ODA in partnership with Netherlands-based architect Braaksma & Roos, for Omnam Investment Group, a real-estate group, the project integrates a national monument over a century old with a contemporary residential tower.

The historic post office, which withstood the bombings of World War II, is being converted into a five-star boutique hotel, offering 238 rooms.

Meanwhile, the newly erected 155m residential tower will house 305 apartments, with 102 units for sale and 203 units available for rent.

The tower’s facade features custom-designed staggered arches and vertical columns crafted from glass fibre-reinforced concrete, paired with an energy-efficient aluminium curtain wall system.

Following the structural completion of POST Rotterdam, the construction team’s attention now turns to the facade’s completion and the interior finishing of the apartments.

The initial batch of rental apartments is fully finished, and the concrete work is finalised, while the complex facade construction has reached the halfway mark.

In September 2024, construction of the Aramco Stadium project began in Saudi Arabia, for which BESIX and ALBAWANI are handling the stadium’s design and construction.
