Construction management courses are increasingly teaching digital technologies and automation. The default method to teach construction scheduling remains the critical path method, which suffers from lack of automation, lack of dynamic change processes, and wrong assumptions about resource and spatial availability. New methods to automate construction scheduling, sometimes referred to as generative construction scheduling, have been developed but are seldom taught in construction management courses. This paper describes the design of a new curriculum to teach one new approach to construction scheduling called the Tri-Constraint Method. The proposed five-lesson, flipped-classroom curriculum is designed to illustrate limitations of the critical path method, explain the theoretical and computational foundations of a generative scheduling algorithm, and provide practical experience through implementation with state-of-the-art software. To measure the impact of the curriculum on student learning, the paper conducts a descriptive statistical analysis, a paired t-test, and an examination of qualitative feedback. Students who entered the course with either low or high prior knowledge of construction scheduling showed significant improvement in their understanding of the key concepts and the algorithmic approach behind the generative construction scheduling. Overall, this paper demonstrates how curriculum design in engineering informatics can combine theoretical understanding and practical implementation to understand generative construction scheduling. The dissemination of this and similar teaching curricula can ensure that future engineering practitioners avoid “black box” implementations of automation software in their future careers.

Digital fabrication is growing in adoption within the architecture, engineering, and construction industry. Because digital fabrication often requires a systematic rethinking of the design process, research emphasizes new understanding is needed for digital systems across multiple areas, including technical development, technological systems, organizational contexts, contractual provisions, and business models. Despite the importance of a system view, the current body of knowledge does not yet provide a consistent identification nor a comprehensive evaluation of factors and their complex interdependencies with one another. To fill this knowledge gap, this work categorizes and identifies the industry needs and perceived benefits under five areas. Next, the authors conducted a questionnaire survey, which received effective responses from 114 industry stakeholders. The authors analyzed the responses using Rao-Scott chi-squared tests of independence to identify 70 pairs of correlated categories. This work further investigates the variables' correlations using heat map visualization. Two variable-correlation mappings are presented as follows: (1) a multiaspect mapping of 292 variable correlations under 10 categories of the industry needs of fabrication information and aspects in design modeling, review, and documentation; and (2) a single-aspect mapping of 26 correlations regarding the industry needs for various benefits of digital systems to adopt digital fabrication. Thereby, this work proposes seven strategy propositions to achieve the benefits of digital systems when adopting digital fabrication in design. The consistent identification of the needs and their interdependencies constitute an integral part of knowledge in construction management.

The use of industrialised construction can help meet the growing housing demand for developing economies in Africa. In order to understand future scenarios for accelerated adoption of industrialised construction, it is necessary to identify the influencing factors. To do so, this paper conducts a formative scenario analysis which is a literature- and expert-based method, focussing on three countries that have high housing demands, i.e. Ethiopia, Kenya, and South Africa. The resulting analysis consists of three parts. The first is the identification of nineteen internal and external influencing factors. These factors range from product performance to policies and regulations. The second is the illustration of the importance of each factor as a function of its relationship with the other factors. The third is the description of three possible scenarios the adoption of industrialised construction may take in the three investigated countries. The findings show that the most important accelerators for the adoption of industrialised construction come from governments’ commitment to invest in future construction and incentivize companies to adopt industrial construction methods and for these companies to produce competitive products. The specific adoption policies to be implemented, however, depend greatly on the specific situation.

Purpose: The dynamic nature and complexity of construction projects make it challenging to ensure that the engineer-to-order (ETO) materials supplied onsite match changing needs. The quick and efficient communication of required changes in material fabrication, delivery and use, due to changes in the design and construction schedules, is needed to address the challenges. This study aims to provide a novel integrated management framework with its embedded informatics to help major stakeholders efficiently absorb agility during communication to deal with required changes and improve workflows. Design/methodology/approach: An integrated management framework is developed that integrates the milestones in look-ahead plans and structured iterative processes for major supply chain stakeholders to quickly disseminate information emanating from changes in design, schedules, production and transportation. A prototype system is devised including the informatics to support the framework, which consists of BIM-RFID functional modules and a central database and uses a client-server architecture. The usefulness of the prototype is illustrated using a construction of part of a fictive but realistic high-rise building. Findings: The integrated management framework with the informatics provides major stakeholders with the ability to coordinate their activities efficiently and stimulate their agility (measured by process time) in planning and controlling material information. Although only a fictive example was used, it is shown that the use of the system is likely to result in a substantial reduction in the time required to deal with required changes when delivering ETO materials onsite (by 18% in the example). Research limitations/implications: The functionalities of the prototype system can be easily scaled up to coordinate changes in the design and scheduling of other types of materials. More functional developments are needed to show the extent of the possible improvement for entire construction projects. Future work should focus on investigating the possible improvements for other types and sizes of construction projects, and eventually in real-world construction projects. Practical implications: By fitting the look-ahead plans into structured iterative processes through digital data sharing, stakeholders increased their capability to quickly capture required change information and resolve associated problems. This is particularly useful for the management of ETO supply chain processes, where prefabricated elements such as ductwork, plumbing, and mechanical systems typically have to be modified because of last-minute design and schedule changes. Originality/value: Unlike traditional information technology (IT) based supply chain management practices, this research is characterized by a process-centered management framework that provides explicit decision points over iterative planning processes for major stakeholders to manage material information. The iterations through digital data sharing allow stakeholders to quickly respond to last-minute changes on site, which fundamentally achieves workflow agility in the construction supply chain context.
