The Group's subsidiary, Pan-United Concrete, set a national record when it poured 18,916m3 for 57 hours non-stop from 31 October to 2 November 2020. This first pour was followed by a second pour of 18,342m3 of concrete in a shorter time of 42 hours non-stop, from 27 to 29 November 2020, to complete the raft foundation.
The mixer truck convoys delivered one truckload of concrete non-stop every 60 seconds. The total concrete volume of the two pours, at 37,258 m3, is equivalent to filling 14 Olympic-sized swimming pools. The previous record of 18,000m3 was in March 2015 for the Marina One raft foundation.
Ready-mixed concrete is produced just in time and typically has a brief two-hour workable lifespan. Pan-United designed a special concrete that remained workable for six hours to ensure the layers bonded integrally to form a solid raft.
The complex logistics planning for the production, delivery and casting of the raft foundation stretched over several months in close collaboration with Hyundai Engineering & Construction (Hyundai), the main contractor of the development.
Ken Loh, chief operating officer of Pan-United, said: "We are thankful to Hyundai for taking all the measures necessary to ensure safe distancing and to greatly reduce any health risks to the teams handling the massive pours. Pan-United also used our contactless processes such as e-delivery orders, e-concrete sampling, e-sign-offs, and our customer portal to minimise physical interaction at the worksite.
"Both mass pours went very smoothly, thanks to the excellent co-operation with Hyundai, and the tremendous team effort of all parties involved. We had full confidence of success in executing this feat, supported by our concrete innovation specialists and with the advanced logistics managed through our digital optimisation platform called AiR1.
"AiR optimises our supply chain, managing the efficiency of our batching plants and ensuring a seamless relay of trucks delivering the concrete. Pan-United will continue to innovate concrete and logistics solutions that can address any complex challenge in building smart cities like Singapore."
