Summary:This paper analyses the current operations and labour utilization rates for a project team engaged in the prefabrication of exterior wall panels, in an existing manufacturing facility in Tempe, Arizona. A current state process is defined for the BIM-to-install process of each exterior insulation and finish system (EIFS) wall panel. Through analysis of the current state, it is found that only 17% of time was spent directly modelling components meant for prefabrication. The remaining 83% of time engaged in modelling is subject to optimization. Based on these findings, a discussion is presented regarding in place scheduling procedures, model and data management protocols, and field to shop verification/validation measures impacting modelling activities. Finally, a presentation of a series of future workflow interventions intended to improve labour utilization rates for modelling and shop personnel while enabling the internal shop ideal for “mass customization through prefabrication” is provided.
