SINGAPORE- The Urban Redevelopment Authority (URA) plans to develop a set of guidelines on subterranean development here, in a step towards creating an underground master plan.

It has called a tender seeking consultants to "develop a comprehensive and holistic framework to enable more extensive use of underground space in Singapore".

The URA said this will help steer future decisions on land use and safeguard areas for potential underground developments.

It said the recommendations and guidelines will also guide the preparation of an underground master plan to "dovetail" with the current land use master plan.

The latter sets out how much needs to be built to efficiently spread the population across the island.

In September, National Development Minister Khaw Boon Wan wrote in his blog that there is scope to do much more in terms of using underground spaces here.

He mooted the possibility of an underground equivalent to the master plan to complement developments above ground.

Before developing guidelines for the URA, the consultants will have to research case studies and the best practices of underground developments around the world.
