This work addresses the problem by proposing a BIM-based framework for automatised coordinated construction specification and quantity takeoff. In addition, besides the BIM authoring tool, they demand other proprietary platforms to obtain the expected outcomes, leading to interoperability issues and representing an obstacle to small and medium architectural design offices in terms of needed investment and customisations inherent to their business model. However, their execution and integration still rely on time-consuming and error-prone manual or semi-automatic interventions to deal with the lack of completeness, suitability and granularity of produced BIM models in design practice, mostly related to elements and activities not digitally represented in these models.

BIM-based construction specification and quantity takeoff (QTO) processes have proven faster and more reliable than traditional methods.
