Construction quality management based on a collaborative system using BIM and indoor positioning

Quality is one of the most vital aspects of a construction project, and inspection is the most important task in construction quality management. Despite the application of advanced information technologies, the omission of check items and in-efficiency of entering inspection results from paper-based inspection records into computers and collaboration among the construction stakeholders remain to be major problems. This paper proposes an approach to make the process of construction quality management more effective and collaborative by developing a system based on the integrated application of building information modeling (BIM) and indoor positioning technology. First, the system requirements of the collaboration platform are analyzed based on the standards for construction quality inspection in China, the technologies to be used for its implementation are justified, and a process model for the collaboration of multiple stakeholders is established. Next, the system architecture is developed, and the algorithm for generating inspection tasks and the technique for integrating with indoor positioning technology are formulated. Finally, the implementation of a prototype system is presented, and the effectiveness and efficiency of the approach for construction quality management are verified by using the system in an on-site test.

Managing collaborative space in multi-partner projects

Collaboration across company borders in multi-partner construction projects has proven to be challenging. An increasing number of projects aim to strengthen such collaboration by collocating project members from different companies in the same physical space. Yet we know little about the management practices required for taking advantage of such a collaborative space. To begin to remedy this shortcoming, we present an in-depth case study of a hospital construction project that applied a collaborative space and focus on the management practices influencing this space. With the help of affordance theory, we identified two types of management practices and show how they transform across project phases. These management practices included designing the physical elements of the collaborative space, and creating shared collaboration practices for the space. We contribute to the construction management literature by taking the first step in conceptualizing the connections between space, management and collaboration practices in the context of multi-partner projects. We suggest managers to consider carefully what kind of collaboration practices the space is expected to enhance and plan the physical and social space to support it.

The formation of a collaborative project identity in an infrastructure alliance project

Inter-organizational projects struggle to build a sense of joint belonging and a culture of cooperation. In evaluating the social processes of collaboration in inter-organizational projects, organizational identity is considered a core concept. To extend existing knowledge of how collaborative identity is formed in inter-organizational infrastructure projects, the study investigates how the specific characteristics of temporary organizations (time, team, task and context) influence identity formation activities. A case study of the first Finnish infrastructure alliance project identifies six key activities supporting the formation of collaborative project identity: (1) articulating a joint vision for collaborative project identity; (2) converging on mutual conceptions of collaborative project alliance philosophy; (3) attaining a shared collaborative mentality; (4) designing ways of working with multiple identities; (5) attaining distinctiveness and (6) legitimizing activities. The findings indicate that identity formation activities are context-dependent, and that the formation of organizational identity differs between temporary and permanent organizations. The findings illuminate how managers can build a collaborative project identity.

Project owners' role in improving constructability of construction projects: an example analysis for Indonesia

Constructability is an approach that links the design and construction processes, which can lead to significant savings in both cost and time required for completing construction projects. Improving constructability of construction projects is the responsibility of all project stakeholders: owners, designers and contractors. As the owners have the most authority in enforcing the implementation of constructability, the owners' awareness of the benefit of improved constructability is the most important. Project owners must be aware that the decisions that are made in the initial stages of planning and design are difficult and costly to change once construction begins. A questionnaire survey was used to gain information on the Indonesian construction project owners' understanding of constructability by assessing the current constructability practices and their impact on project performance. The study shows that project owners in Indonesia do have some understanding of the importance of constructability. However, the traditional approach to project delivery, which is the preferred method by most of them, limits their option for involving construction personnel in the pre‐construction phases.

Organising and Managing boundaries: A structurational view of collaboration with Building Information Modelling (BIM)

The construction industry is currently undergoing digital transformation due to emerging technologies. Hence new forms of organisation are needed. Collaborating with Building Information Modelling (BIM) is complex and challenges the management of projects. The ubiquitous digital information sharing among multi-disciplinary actors in BIM-based projects, activates dense inter-organisational processes. This study offers insights into collaboration with BIM, through the theoretical lens of boundaries. By analysing two projects of BIM-based collaboration in the Netherlands, the interplay between structure and agency of collaboration was discussed. The various artefacts of BIM, as boundary objects were interpreted in multiple ways by different communities of practice and this resulted in poor communication and consequently poor collaboration. The findings challenge the prevalent view of BIM as a software artefact and showed that this view only partially supports collaboration. Additionally, a structurational view (enabled by communication, conflict management, negotiation, and teamwork) as opposed to a structural view of collaboration (e.g. BIM as a software) can fully support the implementation of digital innovations. Finally, the paper revealed a ‘tactical gap’ in the implementation of digital between strategic and operational decision-making needs fine-tuning to ensure better collaboration in projects where digital innovations are adopted. The study concludes with propositions for supporting organisation of teams through integration of activities and the management of BIM-based collaboration in projects beyond merely structural and technological approaches, which dominate the field but from a structurational view instead.

Construction defect management using a telematic digital workbench

Real-time, rich-media data communication between the construction site and the off-site design office is becoming one of the important research areas in information technology for construction. This paper presents the concept of a telematic digital workbench, a horizontal tabletop user interface integrating mobile computing and wireless communication to facilitate synchronous construction site to office collaboration. We demonstrate the capabilities and potentials of this system concept for construction defect management. The on-site crew uses a handheld mobile device to collect defect information and transfers the information to the design office through wireless communication by sending the information to a database listener. The digital workbench application monitors the database and synchronizes the location of the visual information on the site with the 3D model on the server. Integrated with 3D viewing capability in a CAD system, designers can interact with the combined model/site data using a horizontal and vertical screen. A case study compared the telematic digital workbench against paper-based and Pocket PC-based methods for defect management in a controlled laboratory experiment. The case study results show that the telematic digital workbench has the potential to improve the accuracy of matching site data to digital data and reduce information loss between site and office collaboration.
