An excavation system is disclosed for use with an excavation machine having a work tool and with an IPCC. The excavation system may have a location device configured to generate a first signal indicative of a location of the excavation machine, a display, and at least one controller in communication with the location device and the display. The controller may be configured to receive a second signal indicative of a location of the IPCC, and to cause representations of the excavation machine and the IPCC to be simultaneously shown on the display based on the first and second signals. The at least one controller may also be configured to determine a swing radius of the work tool, and to selectively cause an indication of alignment between the IPCC and the swing radius to be shown on the display based on the first signal, the second signal, and the swing radius.

An earthmoving machine comprises a sensor, an implement, and control architecture comprising a controller and configured to facilitate movement in response to a signal indicative of a measured implement position and an implement control value comprising a gain value associated with implement speed. The controller is programmed to execute machine readable instructions to generate a noise value that is based on an error between the signal and a target signal, determine whether the noise value is acceptable to lock the gain value, adjust the gain value to control the implement speed when the noise value is unacceptable until the noise value is acceptable, and operate the machine based on the locked gain value.

A system for controlling a movement of an implement during a dump operation is provided. The system includes a payload detection module associated with the implement. The payload detection module is configured to generate a signal indicative of a current weight of payload in the implement. The payload detection module determines the current weight of payload during a controlled lifting motion of the implement. The system also includes a control module communicably coupled to the payload detection module.

A method for constructing a building structure using gravity and weight of the building structure is provided. The method includes designing an architecture and a construction plan of the building structure, planning an initial box for a structural design, tuning a ground required for construction of the building structure, constructing the initial box as per the planning, constructing an upper floor on the initial box, constructing remaining parts of the building structure including foundation for the building structure, and assembling a plurality of temporary structures to the building structure.
