Hard rocks, water seepage: LTA flags unexpected construction challenges along North-South Corridor
The Land Transport Authority in Singapore reports that construction of the North-South Corridor is facing delays due to unexpected geological challenges, including hard rock and groundwater. These issues have complicated excavation near critical infrastructure, though the project remains ongoing.
Why it matters
Infrastructure projects are vital for urban development, and unexpected engineering hurdles often lead to significant budget overruns and timeline shifts that impact public transit.
Construction of the North-South Corridor viaduct has been affected by unexpected ground conditions and complex utilities diversions.
Listen Summarise Construction of the North-South Corridor faces unexpected challenges with fractured rocks, boulders, and groundwater inflows at Novena and Thomson, complicating excavation and slowing progress. LTA uses careful, compartmentalised excavation to protect MRT lines and manages harder rock formations that delay foundation work, with over 90% of viaduct foundations completed. The NSC project, delayed by Covid-19 to 2029, will feature underground tunnels, viaducts, bus lanes, and cycling paths to reduce travel times and improve transit priority. AI generated
SINGAPORE – Construction of the North-South Corridor (NSC) has hit unexpected ground conditions at Novena and Thomson, complicating works as the project enters its most complex engineering phase, the Land Transport Authority said.
