Prefabrication and modularization helps to reduce cost and schedule time for on-site activities. The use of Building Information Modeling (BIM) helps to improve collaboration and improve the construction process. The improved installation precision provided by BIM Model-Driven Prefabrication can decrease on-site labor time and increase productivity. Prefabrication, Modularization, and off-site construction transfers activities that would have been performed on site to earlier stages of the supply chain. The implementation of Just-In-Time (JIT) delivery transfers the costs and risks associated with inventory to the supplier. Construction Supply Chain Integration can help reduce cost and waste across the supply chain particularly for large and complex buildings. This paper presents a methodology that utilizes a BIM based construction supply chain integration to reduce cost and waste in the construction and offsite manufacturing processes. It utilizes the integration of BIM with the on-site schedule and the manufacturing or fabrication schedule of the different supply chain members. The methodology utilizes the onsite schedule, lead times of prefabricated elements or modules and the transportation logistics to help reduce cost across the supply chain. The information, material and cash flows as well as the transportation logistics is utilized in generating an optimized just-in-time delivery schedule for large and complex buildings. The optimized delivery schedule takes into account the variations in the on-site and off-site schedules to forecast delivery dates of precast elements or fabricated modules.

Organizations are often facing the problem of determining the degree of investment in building information links with their suppliers and buyers to reduce costs, lead times, and quality problems, improve timely customized delivery, increase asset utilization, and improve corporate profitability. One of the critical enablers for an efficient and effective supply chain is timely planning and information processing across the entire value-added chain. This paper presents an analytical model for selecting the right mix of analytical software and hardware alternatives at various planning and execution levels of an organization to remain competitive in a supply chain. Factors such as quality, reliability, flexibility, timeliness and organizational compatibility have been quantified into cost components that form the weighted cost function. The weights of the various cost components of software and hardware are derived from pair-wise comparison. These weights account for the relative importance of alternative supply chain strategies for an organization. A numerical example is presented to demonstrate the applicability of the proposed framework and exhibit the efficacy of the procedures and algorithms.

Lean Principles

Background: This study explores the relationship between the implementation of lean supply chain management and the agility of manufacturing small- and medium-sized enterprises (SMEs). Although some studies have suggested that these two approaches are mutually exclusive, other research finds that they may be applied to different parts of the supply chain or may be compatible through the common elements of process integration and supply chain-wide collaboration. Objectives: Through an investigation of two companies at different stages of lean implementation, this study sought to establish which of these paradigms might be applicable in the context of South African SMEs. Method: Semi-structured interviews were conducted with managers at both companies, and the progress towards lean manufacturing was probed. Results: Company B was found to have made considerably more progress towards a lean system than Company A. Neither company had achieved just-in-time purchasing, and this was identified as a challenging aspect for SMEs. Both companies experienced stockouts and long lead times. The volatile nature of their markets indicated a need for greater agility. Company B was found to have a greater potential for speed, flexibility and response. It is proposed that this may be a direct consequence of greater progress in lean implementation. Conclusion: It was concluded that strategies to implement lean are a necessary prelude to achieving an agile enterprise. This article presents a model incorporating the lean principles that SMEs should adopt in order to achieve agility.

Logistics Process

Over the past decades, the construction industry has been attracted to modular construction because of its benefits for reduced project scheduling and costs. However, schedule deviation risks in the logistics process of modular construction can derail its benefits and thus interfere with its widespread application. To address this issue, we aim to develop a digital twin framework for real-time logistics simulation, which can predict potential logistics risks and accurate module arrival time. The digital twin, a virtual replica of the physical module, updates its virtual asset based on building information modeling (BIM) in near real-time using internet of thing (IoT) sensors. Then, the virtual asset is transferred and exploited for logistics simulation in a geographic information system (GIS)-based routing application. We tested this framework in a case project where modules are manufactured at a factory, delivered to the site via a truck, and assembled onsite. The results show that potential logistical risks and accurate module arrival time can be detected via the suggested digital twin framework. This paper’s primary contribution is the development of a framework that mediates IoT, BIM, and GIS for reliable simulation which predicts potential logistics risks and accurate module delivery time. Such reliable risk prediction enables effective supply chain coordination, which can improve project performance and the widespread application of modular construction.

The Right

The construction industry has been considered as refractory to information technologies. However, new technological approaches, such as the Building Information Modeling (BIM), are becoming increasingly adopted and are promising better collaboration, better flow optimization and greater integration of the supply chain. These changes are preparing the industry for the advent of "Construction 4.0", a more federating concept than BIM. This article explores the concept and shows how tall wood buildings could show the right path and lead the way for the rest of the industry. The research shows that while tall wood construction actually presents the potential to fit the construction 4.0 requirements, current practices are far from being uniform from one project to another. It also illustrates the need for a close collaboration between practitioners and researchers in order to overcome the current challenges.

Abstract Construction 4.0 has become a buzzword since the penetration of building information modeling (BIM), cyber-physical systems, digital and computing technologies into the construction industry. Among emerging technologies, Distributed Ledger Technology (DLT), or blockchain, is a powerful business enhancer whose potential can disrupt projects, AEC (Architecture, Engineering and Construction) firms, and construction supply chain, and in a broader sense, the whole construction industry. This technology has not reached the plateau of productivity due to several barriers and challenges. Previous studies have started to investigate the barriers to implementing DLT in various sectors and segmentations. However, we still need further surveys in the construction industry. This study evaluates the applicability of identified challenges and barriers based on a sustainability perspective. Precisely, we will answer which challenges need to be addressed for the sustainability of the construction industry. To meet the research objective, the Ordinal Priority Approach (OPA) in multiple attributes decision-making (MADM) was utilized. This novel method determines the importance of the sustainability attributes and barriers simultaneously. The results show that DLT implementation needs i) infrastructure for data management, ii) advanced applications and archetypes, and iii) customers’ demand, interest, and tendency, and iv) taxation and reporting. Solving high-ranked challenges is the key to social sustainability from the aspects of ‘supply chain management and procurement,’ ‘transparency, anti-corruption, and anti-counterfeiting,’ and ‘fair operation and honest competition.’

The paper deals with business renovation, effective utilization of information technology and the role of business process modeling in supply chain integration projects. The main idea is to show how the performance of the supply chain can be improved with the integration of various tiers in the chain. Integration is prerequisite for effective sharing and utilization of information between different companies in the chain. Simulation-based methodology for measuring the benefits combines the simulation of business processes with the simulation of supply and demand. The theoretical findings are illustrated with the case study of procurement process in a petrol company. Old and renewed business process models are shown. The changes in lead-times, process execution costs, quality of the process and inventory costs are estimated.
