An autonomous pile driving system identifies using a pile plan map a target location to install a pile. The system autonomously navigates towards the target location. The system autonomously detects using an object sensor system an orientation and location of the pile located within a threshold distance of the system. The system autonomously positions a tool of the autonomous pile driving system based on the detected orientation and location of the pile. The system autonomously picks up the pile using the positioned tool of the autonomous pile driving system. The system autonomously positions the pile based on the target location. The system autonomously drives the pile into ground at the target location.

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.

A gravity-type pore pressure dynamic penetration device for exploration of shallow-layer seabed soil includes a third drop hammer, a second drop hammer, a first drop hammer, a stable empennage, and a probe rod which are sequentially arranged from top to bottom. A sidewall friction sleeve is arranged outside a probe rod lower cylinder. A friction sleeve sensor is provided on an inner sidewall of the sidewall friction sleeve. A first pore water pressure sensor, a conical tip pressure sensor, a temperature compensation sensor, and an inclinometer sensor are provided in the middle of the probe rod lower cylinder. A second pore water pressure sensor and an acceleration sensor are provided in the middle of a probe rod upper cylinder. The tail portion of the probe rod, that is, the upper portion of the probe rod upper cylinder is connected to the stable empennage.

A method and a resulting PLDCC slab formed by that method results in elevating the lowest floor (LFE) of a proposed structure to be built on a selected building site to a height at or above the base flood elevation (BFE) as each term is defined under 44 CFR 60.3. The BFE is retrieved from the Flood Insurance Rate Map (FIRM) by locating the building site thereon. The proposed structure defines the LFE. With a height of the existing grade beneath the LFE, a difference between the BFE and the height of the existing grade beneath the LFE determines a PLDCC height. A form constructed to contain a volume of cellular lightweight concrete (PLDCC) having a PLDCC height that equals the difference. A pour of sufficient PLDCC volume then fills the form to a depth at the LFE equal to or exceeding the PLDCC height.
