A method for constructing a building on a water-body. The method includes piling a plurality of piles on a bed of the water-body for laying a foundation for the building. The method further includes marking a reference-mark on each of the plurality of piles at a predefined-distance from a surface of the water-body. The method also includes cutting each of the plurality of piles along the reference-mark. The method further comprises installing a first pile-cap, having a plurality of guiding elements extending therefrom, over a first set of piles of the plurality of piles. The method also comprises installing a second pile-cap over a second set of piles of the plurality of piles.

The invention relates to an arrangement for supporting a thin-walled steel pile (5; 17; 26; 35) in an impact pile driving device, the arrangement comprising a supporting surface (4; 14; 23; 31), to which the steel pile (5; 17; 26; 35) can be supported, and in which arrangement the supporting surface (4; 14; 23; 31) is provided with one or more absorbing surfaces (6; 16; 25; 33) to be placed against the end of the wall (8; 18, 26; 36) of the steel pile (5; 17; 26; 35). In the arrangement according to the invention, the absorbing surface (6; 16; 25; 33) is configured to shape the end of the wall (8; 18; 27; 36) of the steel pile (5; 17, 26; 35) coming against the absorbing surface (6; 16; 25; 33), by the effect of the impact driving of the steel pile (5; 17; 26; 35), so that at least the part of the wall (8; 18; 27; 36) at the absorbing surface (6; 16; 25; 33) of the wall (8; 18; 27; 36) is shaped against the absorbing surface (6; 16; 25; 33), wherein the movement of the wall (8; 18; 27; 36) in the direction of a plane transverse to the direction of impact driving of the steel pile is prevented, at least at the head of the steel pile (5; 17; 26; 35). Also, the absorbing surface (6; 16; 25; 33) in the supporting surface (4, 14; 23; 31) can be configured to be shaped by the effect of the impact driving of the steel pile (5; 17, 26, 35) so that the absorbing surface (6; 16; 25; 33) is shaped against the part of the wall (8; 18, 27; 36) of the steel pile (5; 17; 26; 35) at the absorbing surface (6; 16; 25; 33), whereby the movement of the wall (8; 18; 27; 36) at the head of the steel pile (5; 17; 26; 35) is prevented. The invention also relates to a method for arranging the support of a steel pile (5; 17; 26; 35) in an impact pile driving device.

An assembly supports a concrete slab foundation above a ground surface while being poured and hardened. The assembly includes forms, each of the forms having a frame. Lower rollers are mounted to each of the frames for rolling each of the forms onto the ground surface. Upper rollers are mounted to each of the frames at an elevation above the lower rollers. Upper decks are placed on top of the upper rollers. Each of the upper decks has an upper surface configured to receive the concrete while being poured and hardened. The upper rollers of each of the forms are in rolling engagement with a lower side of one of the upper decks, enabling the forms to be rolled out from under the upper decks after the slab foundation has hardened.

A cutting tool adapter for creating an underpinning structure and method of creating the underpinning structure are provided. In some examples, the cutting tool adapter may connect a cutting tool to a working machine arm to enable the cutting tool to cut and dislodge soil below an existing foundation or structure. As the soil is cut and dislodged, it is mechanical mixed with an additive, such as a cementitious material, via the cutting tool. The mixed soil and additive may then harden in the area below the existing structure or foundation to create an underpinning structure to provide additional support for the existing structure or foundation.

A system and method detect at least one mechanical locking position of a drill string in a soil drilling machine. According the system and method, there are: a sensor apparatus which is configured to detect first data indicating the position assumed by the top of the drill string and second data indicating the position assumed by the bottom of the drill string. A control unit calculates the estimated length of the drill string based on the data and to compare the estimated length with a reference length value. A pair of kelly rods is in a mechanical locking position; and a signaling apparatus is configured to signal when the estimated length corresponds to a reference length value.
