The invention relates to a method for monitoring the ramming of a ram post (1) into the ground. A succession of blows are struck on the ram post (1) via an impact driving device (3), causing the ram post (1) to be rammed into the ground. Parameters for the load-bearing capacity of the ram post (1) in the ground are ascertained during the ramming of the ram post (1) via a monitoring unit (14).

There is provided a linear electric machine comprising a mover connected to a ram block for striking a pile, a processor operatively connected to the linear electric machine and configured to determine a total target kinetic energy for striking a pile using a ram block connected to a mover of a linear electric machine of the piling hammer, determine a first portion of the total target kinetic energy for striking the pile at least based on a mass of the ram block, determine a second portion of the total target kinetic energy for striking the pile based on the total target kinetic energy and the first portion of the total target kinetic energy, and control the linear electric machine to accelerate the mover based on the determined second portion of the kinetic energy for striking the pile by the linear electric machine.

A device for calculating construction assistance information includes: an acquisition unit that acquires, from a vibratory hammer construction machine, information that contains at least values indicating a eccentricity force of a vibratory hammer which the vibratory hammer construction machine imparts to a construction object, the number of impacts, and a depth of penetration of the construction object; and a calculation unit that calculates a accumulated impact force indicating a work load of construction on the basis of the information acquired by the acquisition unit.

In a piling construction management method a support strength of a hole bottom is measured with a penetration testing device before erecting a piling in a piling hole. The piling is erected in the piling hole when the measurement is at least a prescribed value. The penetration testing device has a knocking block with an integrated penetration shaft and the block is struck by a drive hammer in free-fall. The penetration testing device determines the support strength from the number of impacts required for the penetration shaft to penetrate to a prescribed depth from the hole bottom.

An autonomous off-road vehicle (AOV) autonomously performs a pile driving operation by driving a pile into the ground at a location identified by a pile plan map. The AOV detects one or more attributes of the pile using one or more sensors during or after the pile driving operation. The AOV determines whether the one or more attributes of the pile exceed respective tolerance thresholds. The AOV performs a quality control action in response to determining that the one or more attributes of the pile exceed the respective tolerance thresholds. The one or more attributes include one or more of a location and an orientation of the pile, and the quality control action is performed in response to determining that the location or the orientation of the pile exceeds the respective tolerance threshold.
