residential, commercial, and industrial structures.

all weathers; inside in dusty industrial plants and mills; to state-of-the-art clean-rooms in hospitals and

knowledge of the principles of electricity, circuitry, and power distribution systems, and familiarity with

construction tradespeople, such as carpenters, lathers, cabinetmakers, plumbers, and heating, ventilation( K8 y$ v e( N8 N: I' ]
