Window Proximity Tracking Method for Tall Building Construction

Window work is a major process that must precede the finishing work and has a high influence on the entire construction period of a tall buildings. Conventional window work in a tall building construction typically begins several floors below the structural work floor to prevent interference with the auto-climbing system and with the lifting of the window frame. This, however, causes a gap in the process between the structural work and the window work, which increases construction duration and cost. This study proposed a window proximity tracking method for tall building construction (WPTM) that could reduce construction cost and duration by minimizing the process gap. In a case study, the WPTM showed lower construction costs and a shorter duration than those of the existing method.
