Building information modeling warnings towards a deadline

In large projects, it is common to see BIM warnings accumulate into the thousands. These warnings can be design and reworks related errors. The objectives of this research are to test the hypotheses that most warnings occur up towards a deadline and identify whether the number of warnings increases according to model size. An empirical data collection was used on 33,106 warnings over 32 weeks, then analyzed with descriptive statistics to test the hypothetico – deductive method. The results found that towards a deadline there is an average increase of 9% in warnings from four weeks before the deadline. Although when the model size becomes a part of the equation there is a 4% decrease in warnings per megabyte file size in the same time period. This study finds that more warnings happen close to deadlines, not because of more mistakes, but because of an increase in the work being done.
