Geoss Good Practice For Installation Of Jacked Foundation Piles In Singapore -
The jacking rig must be leveled accurately using built-in hydraulic jacks. The first pile segment is pitched into the grip mechanism. Engineers must check the verticality of the pile in two orthogonal directions using plumb bobs or digital spirit levels. The structural verticality tolerance must be strictly maintained within 1 in 100. 2. Penetration and Splicing
Piling specialists (categories G2 and G3) must have jacked rigs with a minimum counterweight of 200-ton and 400-ton respectively. The jacking rig must be leveled accurately using
Jacked foundation piling—commonly known as the jacked-in or hydraulic pressed piling method—has grown rapidly in popularity within Singapore’s dense urban landscape. As a static displacement piling method, it offers a vibration-free and low-noise alternative to traditional driven piling, making it ideal for projects situated near historical structures, sensitive transit lines, or densely populated residential estates. sensitive transit lines
The Geotechnical Society of Singapore ( GeoSS ) published its landmark guidelines, to standardize the rapid adoption of hydraulic jacked piling systems. The jacking rig must be leveled accurately using
