Realtime 4D CAD = RFID for Project Progress Management

Abstract

This research presents the integration of 4D CAD with RFID (Radio Frequency IDentification) technology to improve the progress management process. The objective of this research was to build an effective and efficient project progress management framework by integrating 4D CAD with RFID technology under a collaborative environment throughout the supply chain of a construction project. This research proposes a system, named 4D+RFID, that presents building elements in 3D CAD models according to as-built progress, where the as-built information is collected in real-time by sensing the progress throughout the supply chain using RFID. 4D+RFID developed in this research aims at supporting processes with a focus on structural and curtain wall elements, such as steel columns and beams, concrete slabs, and curtain walls, which are typically on the critical path of project schedules in high-rise building construction projects. The process is that RFID is applied to sense the progress status of ordering, delivery, receiving, and erection of building elements, and then the as-built progress information is presented in 3D CAD models. 4D+RFID is under development for use in a high-rise office building construction project in downtown Seoul, Korea.

Spatial Mapping Approach to Component Tracking Using RTLS System

“…Owing to the need for visualizing the status of tracked components for effective progress monitoring, other researchers have also proposed approaches to integrating the physical tagged components with the virtual models using RFID technology: Chin et al (2005) who proposed the integration of 4D CAD and RFID tags for progress monitoring in supply chain management. RFID tags were placed on structural elements such as structural steel and curtain walls, to sense their status from the ordering stage through the delivery, receipt, and finally to the erection stage.…”

An Overview of Approaches for Utilizing RFID in Construction Industry

“…Tracking materialslcomponents and related information: In this group of studies, several systems were envisioned, within which materials/components were tracked in an automated or a semi-automated way through a construction supply chain, i.e., as they are relocated at manufacturing plant's storage yard, sent to/received at the construction site, relocated before installation and installed to the facility [7,8,9]. The information on where the materials are, would be used for locating materials/components and progress monitoring by different parties.…”

Optimization of Aggregates Supply for Concrete Plants

“…Additionally, the amount of information necessary for construction processes has also increased. Some support came with the introduction of technology radio frequency identification (RFID) and wireless sensor network (WSN), which in the future may play a key role in improving collection and sharing of information in the supply chain process [4,5,6,7,8]. It is also necessary to take into account the changes which the intense development of the Building Information Modelling (BIM), observed in the recent years, brings to precast concrete industry [9,10].…”
