Besides, it provides greater value delivered at the maintenance and operation stage, reducing owner-operating expenses. To maximize BIM use benefits, owners, such as the public sector, can directly affect the enterprise viability by selecting the project delivery system. That has led to the search for alternatives contractual requirements to traditional models. The main objective of this study is to investigate contractual requirements that influence BIM adoption process in public organizations. The research strategy adopted was a survey. Sixty-nine professionals from Brazilian Architecture, Engineering, Construction and Operation (AECO) sector answered a digital questionnaire. The target public was BIM adoption experts, academic professionals and public managers from fourteen public organizations that have already begun BIM implementation. The investigation revealed that project delivery systems considered with the greatest potential to maximize the benefits of BIM use were those less adopted and disseminated in the Brazilian public sector. The results also show that contractual requirements for BIM adoption might consider aspects, such as, technical qualification in public procurement, methods and tools for BIM deliverables quality checking, items that must compose a BIM mandate, and favorable cost-benefit factors for the development of BIM component virtual libraries by public organizations. The main contribution of this research is to provide a better understanding of contractual requirements that could be incorporated into project delivery systems to maximize BIM benefits in the public sector.

The artifact proposed is a set of constructs for evaluating the utility of 4D BIM simulations for transportation waste reduction. The authors performed two learning cycles using empirical studies in projects A, B and C. The construction process of cast-in-place (CIP) reinforcement concrete (RC) was selected to demonstrate and evaluate 4D BIM's utility. The empirical studies focused on understanding the current transportation waste, collecting actual performance data during job site visits and demonstrating the usage of 4D BIM.FindingsIn the first cycle, 4D BIM successfully allowed users to understand the CIP-RC process's transportation activities, which were modeled. In the second cycle, 4D BIM enabled better decision-making processes concerning the definitions of strategies for placing reusable formworks for CIP concrete walls by planning transportation activities.Practical implicationsIn Cycle 2, three different scenarios were simulated to identify the most suitable formwork assembly planning, and the results were compared to the real situations identified during the job site visits. The scenario chosen demonstrated that the 4D BIM simulation yielded an 18.75% cycle time reduction. In addition, the simulation contributed to a decrease in transportation waste that was previously identified.Originality/valueThe original contribution of this paper is the use of 4D BIM simulation for managing non-value adding activities to reduce transportation waste. The utility of 4D BIM for the reduction of those conflicts considered three constructs: (1) the capacity to improve transportation activity efficiency, (2) the capacity to improve construction production efficiency and (3) the capacity to reduce transportation waste consequences.

The integrated use of Building Information Modeling (BIM), Internet of Things (IoT) and Radio Frequency Identification (RFID) technologies can enable tracking and improve construction site-related processes. Specifically, there is a lack of studies regarding the tracking of metallic formworks during the execution phase of the cast in place concrete wall constructive system, in which quality issues often imply rework and delays. The main objective of this paper is to design a conceptual framework for tracking physical resources at construction sites using BIM, IoT, and RFID, in which the metallic formworks are the object of study. This study is based on a Systematic Literature Review, which was conducted to identify requirements to connect the concepts and technologies in the conceptual framework and to develop an integrated system that uses the aforementioned technologies. Moreover, a preliminary proposal of an integrated system associating the RFID tags with the ID of equivalent virtual elements in BIM and storing information from the formworks in a database, which communicates with the virtual model, was presented. The conceptual framework and the preliminary proposal will be used for the design of the system prototype for future implementation in real construction environments.
