Through studying the characteristics of the work of interior electric wiring in apartment houses, in which, different construction methods of partition were used, following facts are found: 1) Electric wiring spends considerable amount of time; 2) Electric wiring spends more time in houses using panelized partition; 3) About 1/3 of the time of electric wiring is spent on wiring work occured within the walls of partition; 4) Sometimes, more efficient construction methods of partition may cause an increase of time spent in electric wiring; 5) Construction methods of partition influence working process and schedule of electric wiring. Finally, on the basis of analyses, suggestion about how to keep the efficiency of the work of electric wiring from negative influence during developing new construction method of partition for apartment houses, is presented.
