Geoss Good Practice For Installation Of Jacked Foundation Piles In Singapore Link [top] Jun 2026

For specialized technical guidelines and the latest industry standards, consulting with GeoSS is recommended.

The technology — pioneered by manufacturers such as Giken — uses hydraulic rams to press piles into the ground with no noise or vibration, making it ideal for Singapore’s noise-sensitive urban environment. The National Environment Agency (NEA) actively promotes jack-in piling as a quieter construction method and provides funding support for contractors adopting such equipment.

In standard Singapore practice, the hydraulic jack drives the pile section into the ground while modifying force in incremental steps until reaching a designated target value, usually varying between . For specialized technical guidelines and the latest industry

Proper alignment and welding avoid pile damage.

The Geotechnical Engineering Office (GEOS) provides guidelines for the installation of jacked foundation piles in Singapore. The guidelines cover various aspects, including:
