The invention discloses an ultrahigh tower construction progress management system and method based on a BIM technology, and relates to the field of building construction management. According to the invention, progress management planning performance in a construction project is high, a BIM model is adopted, and traditional paper files and complex data records are abandoned, so that engineering progress is more intuitive and concise in performance; different color representations are set for different construction teams, so that the visualization effect is good, and the distinguishing performance is high; a monitoring module is further arranged, so that remote monitoring can be conveniently carried out by a progress management party, the situation of wrong report and false report of the construction teams can be found in time, and information gaps are reduced; for ultrahigh tower type buildings, smooth implementation of early-stage installation work of frameworks, formworks and the like can be effectively guaranteed, and the concrete foundation pouring efficiency is improved; and the material consumption amount of the construction project can be pre-judged, engineering material preparation is made for the construction teams in advance, and the completion efficiency of the construction project is further improved.
