Pan-United Corporation has announced that its subsidiary, Pan-United Concrete, has successfully concluded a mass pour of 10,250 cu m of concrete for casting the 5-m-thick raft foundation of The Skywaters at 8 Shenton Way in January 2025. This 63-storey mixed-use development towers 305 m high and sits on a site spanning 10,984 sq m. Upon completion in 2028, The Skywaters will be Singapore’s tallest building.
Collaborating closely with the project’s main contractor China Harbour Engineering Company Ltd (Singapore Branch), the mass pour was executed non-stop for 35 hours with one truckload of concrete delivered to the site every two minutes.
The smooth delivery was made possible by Pan-United’s technology arm, AiR Digital. Leveraging its AI-enabled optimisation solution, the AiR Digital system effectively managed the complex logistics of the mass pour. For instance, its fleet optimisation and auto-replenishment of raw materials ensured that trucks shuttled between the plant and project site with zero disruptions. In addition, the mixer trucks could queue seamlessly to deliver concrete without delays.
The Skywaters is Singapore’s first project to use the highly durable Grade 105 PanU Super High-Strength concrete, which reduces the amount of concrete and reinforcements required for the raft foundation. To reduce the embodied emissions of the project, The Skywaters is also being built with PanU CMC+, which permanently traps industrial waste carbon dioxide in the concrete, effectively making the building a carbon sink. Furthermore, PanU Cool concrete was utilised for its industry-leading temperature control and very high flowability.
Lim Han Kwong, chief operating officer of China Harbour Engineering Company Ltd (Singapore Branch), said, “The mass pour would not have been possible without the strong leadership from China Harbour Engineering Company and the seamless collaboration among all stakeholders, including the unwavering support from the entire Pan-United team. This project showcased Pan-United’s exceptional coordination skills and their commitment to delivering on their promises.”
Ken Loh, chief executive officer of Pan-United, said, “We take great pride in our involvement in this landmark project and are grateful for the confidence and trust that China Harbour Engineering Company has in Pan-United. The successful completion of the casting was very much a combined effort between China Harbour Engineering Company and Pan-United.
“Our teams collaborated closely to carefully plan and execute the pour round-the-clock. We are glad that Pan-United’s years of concrete innovation and use of advanced technology have proven useful in meeting the challenge of setting new records in landmark projects.”
The Skywaters, positioned at the intersection of the central business district, Marina Bay and the future Greater Southern Waterfront, is being developed by a consortium led by Perennial Holdings. Designed by Skidmore, Owings & Merrill, the development features luxury residential units, retail space, offices and a hotel.
