Challenge Transformer upgrades and expansions were required for a tightly constrained area with limited expansion possibilities and no existing conditions documentation. Clearances required from energized points did not allow critical measurements to be taken without a shutdown.
Solution Laser Scanning and 3D Modeling provided highly detailed and accurate existing conditions plans through 3D scanning and modeling. Designer was able to ensure that new transformer fit within existing condition restraints and also maximized future expansion areas. The laser scanning allowed all clearances to be maintained while still obtaining highly accurate measurements.
