Development and Application of an Integrated Management System for Off-Site Construction Projects

Abstract

The off-site construction (OSC) method has attracted the interest of experts to resolve productivity stagnation and lack of skilled workforce and to reduce greenhouse gas emissions in the construction industry. Due to the unique characteristics of OSC projects, wherein building elements are produced in a factory, transported, and installed in the field, a management approach that differs from the management techniques of previous construction projects is required. Accordingly, with this study, we examined the characteristics of OSC projects and derived key management items through literature review, case analysis, and expert meetings to develop an integrated management system for OSC projects (OSC-IMS). The proposed system, OSC-IMS, integrates the entire supply chain of the OSC project. It includes the following functions: drawing management, scheduling and planning, site installation planning, production planning, production monitoring, shipping and transportation, delivery and inspection, site installation monitoring, and progress payment management. To verify the applicability and effectiveness of OSC-IMS, it was implemented in four projects. The application of the system to the case studies demonstrated the improvements in work efficiency and accuracy and decreased waste time in every work step. The findings indicate that the system can enhance project performance. This study contributes to the identification of the features and key elements of OSC management such that these factors can be linked with managing system development. This work describes the overall effect of the proposed system on real projects.

“…Furthermore, provided these facts follow the appropriate section, the system will convert it into an output which is the problem solution. However, for facts that are not appropriate, the system will continue to search for the then algorithm section until it discovers the right solution as output [26], [27].…”

Complexity and Dynamics in Construction Project Organizations

“…Due to scale-up and convolution of construction projects, as well as the increasing introduction of collaborative project implementation techniques such as CMAR, IPD, and OSC, an individual or organization cannot retain the knowledge and capabilities needed to manage all issues that occur during project execution. Thus, there is a growing emphasis on collaboration among different organizations to achieve project goals [65]. There may be two reasons for this.…”

Requirements Analysis for Development of Off-Site Construction Project Management System: Focusing on Precast Concrete Construction

“…The technical level of the OSC project management system is still in its infancy, lacking systematic establishment of these requirements and functions [13]. Identification of the requirements in the entire development process of the management system is a key process for the system efficiency and the performance of actual work in determining the procedures, functions, communication methods, and data processing methods using the management system.…”
