eqBQ relies heavily on the use of BIM modeling to generate the quantities before exporting them to produce the BQ. Factors affecting BIM may hinder its ability for use of quantity takeoffs and the production of the BQ. Firstly, material takeoffs in BIM require the use of different methods. For example, during manual calculation of the one-brick wall superstructure, the value of 84.86 can only be gotten after subtraction from 95.91 (the external wall for the gable ends). This kind of deduction will not be possible on the software itself and that is not how the software is designed to work as well. A different manipulation would have to be done in order to get the value of 84.86. Therefore, estimators must adapt their takeoff techniques in order to extract accurate data from the model. This would mean that those performing the takeoff must be trained to use the software. As only trained quantity surveyors can use the software, it limits the population of quantity surveyor that can use the software. For untrained quantity surveyors, this software would result in them spending more ti...
