“…On the other hand, Maciel and Corrêa (2016) state that deficiencies in the fabrication and preassembly shop may be related to poor management, communication, and information exchange between stakeholders: designer, builder, and supplier. Therefore, it will be very important to establish processes that allow integrating the construction management and the supplier's supply chain by efficiently using information technologies under a collaborative environment.…”

Reworks and delays in production processes are commonly found in construction projects associated with a low level of industrialization and a lack of design constructability. To promote industrialization, improve project constructability, and reduce the execution time, we implemented the Virtual Design and Construction (VDC) methodology. An industrialization strategy was established using a prefabricated reinforcement cages system (PRC) elements in an 870-meters bridge construction project in Lima, Peru. The objective was to improve the project buildability with high industrialization of the steel rebar works. We replaced the traditional on-site cutting and bending steel reinforcement processes with an industrial process that integrates construction management with the supply chain through Building Information Model (BIM). As a result, the level of industrialization of the PRC elements of the bridge substructure and superstructure reached 85% and 40%, respectively, aligned with a 16% execution time reduction of the project.

“…This standard assists the exchange of information between rebar detailing software and CNC bending machines or PPS (Production Planning and Scheduling) software without manual intervention. The reinforcement data is exchanged through an ASCII (American Standard Code for Information Interchange) encoded text file and, as other CAD-CAM (Computer-Aided Design -Computer-Aided Manufacturing) formats like BVBS which is based on 2D drawings (Maciel and Corrêa, 2016). Jalali (2018) in her research presented an example of BVBS data string of corresponding item (Fig.…”

While the AEC industry is moving towards digitalization off-site rebar prefabrication became a common practice. Now most companies use a long-established standard order processing method, where the customer submits 2D paper or PDF-based drawings. Subsequently, the manufacturers are obligated to make additional detailing, redrawing, calculations, and preparation of other required information for manufacturing. Thus, in this typical scenario, there is a great repetition of the same tasks, with the obvious loss of time and increased likelihood of human error. However, improvements can be made by the application of advanced digital production workflow and the use of open BIM standards (e.g., IFC, XML, BVBS). Therefore, this paper presents the typical data flow algorithm in contrast to the automated data flow for reinforcement manufacturing. Further, the two approaches are compared and analyzed based on Multi-Criteria Decision Making (MCDM) methods. The results have shown promising prospects for companies willing to automate their data flow processes by the use of 3D drawings and digital data from the BIM model in their plants.

“…As the authors of the present article are working in the development of a IDM / MVD for the automated cut and bend of reinforcing bars as a BIM process [17] [18], it was decided to use this scenario to illustrate the mapping between IDM (BPMN) to Petri Nets (Figure 2). .…”

Building Information Modeling (BIM)-based processes are increasingly being adopted worldwide. With it, possibilities to exploit digitization had been appearing for the AEC sector. In that context, the present work aims to investigate how, and in which form, a Cyber-Physical System (CPS), one of many different but complementary technologies associated with the future of manufacturing, could be employed in the Construction industry. Recognizing that the core of CPS should be the dynamics of construction processes, the initial focus is in how to develop Process Data Models (virtual) that could communicate with Product Data Models (BIM models), and receive/send data in almost real-time from/for the existent hardware (sensors and actuators) in the physical production processes. This article present some preliminary work based on the standardized methodology of IDM/MVD, which are part of the buildingSMART solution for interoperability along with Industry Foundation Class (IFC) data schema. The proposed methodology considers an IDM modelled in Business Process Modeling and Notation (BPMN) language in such detail as to expose the workflow of production. The contribution in this context is in mapping production processes in BPMN notation into Petri Nets (PN) semantics. Petri Nets are an adequate model to construction processes, with precise semantics and largely used in the simulation of discrete events. With PN models it would be possible to develop the BIM-based control strategy, and test and implement it in real controllers. An illustrative example is provided in the context of automating cut and bend of rebar.
