A shortage of granite due to an Indonesian export ban has left several construction projects in Singapore in a rocky state.
Contractors told The Straits Times that there have been delays for various projects since the middle of this month.
A Building and Construction Authority spokesman said yesterday that the industry was still importing granite aggregate from "many other regional sources", though it declined to name them. She said it was working with importers to ramp up supply from these "diversified" sources.
"If needed, the Government will activate the release of the national stockpile to ease the temporary disruption in supply," she added.
