A venue transformation and construction method is disclosed that creates a tropical style swimming lagoon at an infield site of a race or activity circuit facility, the infield site being contained within a race or activity circuit perimeter. The transformation includes demolishing at least part of the infield site; excavating material from an area within the infield site; and forming a basin for a large water body having a surface area of at least 3,000 m2. Water containment walls are constructed on a first section and a sloped access area is formed on a second section of the basin for a beach. A barrier is included to control access to the beach. At least one additional recreational facility is constructed around the basin and a connection is provided that connects the outfield of the race or activity circuit with the infield site to allow transit of vehicles and/or people.

The present invention proposes a ground compactor with a ground compaction drum rotating about a rotation axis during compaction of a substrate, wherein the ground compaction drum includes a deformation sensor for detection of an elastic deformation of the ground compaction drum in order to determine a degree of stiffness of the substrate.

A sensor system is for measuring the profile of a snowpack along a snowpack passage. The sensor system has a probe and at least one processor. The probe has at least one first sensor set. The first sensor set has at least one first photoemitter for emitting light and at least one first photodetector for detecting light. A processor is provided for receiving output signals from the first sensor set. The processor is for calculating a snowpack profile.

Portable mini dynamic penetration test (MDPT) device includes a probe for penetrating into soil, the probe defining a cylinder with a cone head at a distal end of the probe and a rod attached at a proximal end of the probe, and a drive-weight assembly for driving the probe into soil, the drive-weight assembly including an approximately 17.5 lb hammer. In operation, the MDPT device is configured for use by an operator, wherein the operator can carry the MDPT device to a soil test site, set up the MDPT device at the soil test site, and test soil condition at the test site with the MDPT device.

A soil probing device includes comprises a probing rod with a measuring probe, a driving means for penetrating the probing rod into the ground, generators for generating acoustic compression and shear waves into the ground, detectors for detecting the said generated acoustic compression and shear waves. The detectors are built into the measuring probe. Also the generators are built into the measuring probe at positions that are interspaced at fixed distances in a z-direction from the detectors in the measuring probe. A processing unit CPU is provided for calculating velocities of the generated acoustic compression and shear waves that get to travel from the generators towards the detectors through local ground layers that lie adjacent the measuring probe in between the generators and detectors.

The invention relates to methods for determining a soil class, in which an earth borehole is introduced into the ground by means of a ground drilling device with a drill head, wherein a parameter of the ground drilling device and/or an operational parameter of the ground drilling device is assessed during the determination of which soil class is involved.

A system configured to determine a property of a paving-related material is provided. The system includes a measuring device configured for measuring a property of a paving-related material and a cellular computer device configured for being in communication with and receiving data from the measuring device.

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.

A penetration testing apparatus for testing the bearing strength of ground, soil layers, base-courses, subbases and subgrades without the need for much manual operation, includes the following components operatively connected together, comprising a frame support (5) which supports an actuating apparatus (7), power supply apparatus (9), movable carriage assembly (13), ground penetrating member (15), carriage drive mechanism 17 and ground stabilizing means (18), operatively connected together to carry out a ground test. The movable carriage assembly (13) movably supports one ground penetrating member (15). The movable carriage assembly (13) is movably supported by the frame support (5) such that power from the actuating apparatus (7) slidably and mechanically moves the carriage assembly (13) up and down with the ground penetrating member (15), on a portion of the frame support (5), to cause the ground penetrating member (15) to contact or penetrate the ground when the carriage assembly (13) moves down and be slidably moved back up the portion of the frame support (5) to repeat the sliding down movement again.

A system is provided, including a remotely operated machine having: a coiled rod with a probe to be penetrated into subsurface by uncoiling the rod; a tracking unit determining a position of the machine; and adjustable support legs for stabilizing and levelling the machine; a remote workstation having a user interface for data input and output; a tracking control unit for tracking movement of the machine based on its position; a levelling control unit for controlling the support legs; and a deployment control unit for controlling uncoiling of the rod and penetration of the probe into the subsurface; the tracking control unit, levelling control unit and deployment control unit configured to communicate with the remote workstation allowing operation of these units to be monitored, initiated and/or controlled via the user interface; and the tracking control unit, levelling control unit, and deployment control unit configured to transmit a signal indicating successful execution of its operation.
