ICT Construction Technology

PPT System™ (Press-in Piling Total System)

The PPT System is an integrated construction system based on the combination of its advantages with ICT.

It automatically optimises press-in conditions such as press-in speed, chuck revolving speed and press-in/extraction stroke in real time through the estimation of ground information with data on press-in force, torque, etc. acquired during pile press-in operation.

The PPT System, a technology compatible with the i-Construction (productivity improvement project promoted by MLITT, Japan) contributes to energy saving, labour saving and productivity improvement at construction sites.

Pile Installation Quality Control System - Implant NAVI™

The Implant NAVI™ acquires data of embedded depth, displacement, and inclination of piles being installed in real time. It is an integrated system that realises high quality pile installation control, automatic creation of various as-built documents, and creation of 3D drawings.

Press-in Monitoring System

Press-in monitoring data for each single pile, such as press-in force, auger torques and press-in time, is available for scientific analysis. Such data can be linked to borehole data to optimise operation settings for each ground condition. This enables proper decision to be made in case of any change in soil strata or presence of any underground obstacles.

Monitoring of an Implant™ Levee

Since July 2013, the soundness of the levee and performance during an earthquake has been constantly monitored by remote communication, based on measurement data from instruments installed inside the embankment.

Press-in Monitoring and Date Logging System

By measuring information and converting it into data during construction, such as press-in force and press-in speed, in real time, the state of press-in work can be managed scientifically. By linking this data with the soil histogram, it is possible to accurately determine the optimal press-in setting value for the ground, and address the obstacles.

Automatic Operation System

The automatic operation system allows iterative execution of the optimal press-in work regardless of the site conditions, by accurately executing the press-in machine based on scientifically clarified construction theory (practical theory for efficiently building high-quality completed piles in press-in construction) as the "The Press-in Essentials".


It can monitor machine conditions of individual SILENT PILERTM such as operating situation, maintenance records and its location. Quick advises for any technical troubles are available promptly and appropriate information can be provided timely to prevent troubles in advance.
