  • Patent number: 6934629
    Abstract: A three dimensional structure is precisely positioned at a desired location. A viral model of the structure of interest is created and stored in a computer memory. Some time later, remote sensors are placed in selected positions on the structure of interest. The sensors are configured so as to provide real time location, attitude and orientation information regarding the structure and may consist of GPS remote units, tilt meters, gyro compasses, and pressure sensor. The position of each the remote sensors on the actual structure is also recorded in the computer memory so that the virtual model accurately reflects the configuration of the structure. As the structure is being positioned, the real-time location, attitude and orientation information produced by the remote sensors is monitored at a base station and used to update the virtual model. In this way, the virtual model accurately reflects the current location, attitude and orientation of the structure.

  • Patent number: 5841353
    Abstract: Determination of the verticality of various structures such as high rise buildings and towers is enabled through various methods involving use of a series of tiltmeter devices, a remote positioning system, or a combination of both. These methods are particularly useful in monitoring deviations from vertical during construction work and adjusting a jumpform. The tiltmeters are typically arranged in a line on the structure and polled to characterise varying tilt states in which displacement of each device increases with height up the structure. The remote positioning measurements are typically made in real time using a satellite based system such as GPS. Departures of a survey point on the jumpform from a vertical target line may be used to monitor verticality during the construction process.
