Implementing Radio Frequency Identification in the Construction Process

This paper provides construction industry owners and contractors with information about enhancing their operations using radio frequency identification (RFID) technology. Radio frequency identification involves the use of tags, or transponders, that collect data and manage it in a portable, changeable database; communicate routing instructions and other control requirements to equipment; and can withstand harsh environments. A construction industry-RFID supplier workshop was held to disseminate information about this technology and to generate suitable application ideas for the industry. With the information gathered during the workshop, one application idea was selected and pilot tests conducted to learn more about RFID and its applicability to the material procurement process on a construction site. The pilot tests showed that RFID tags reduced the time required to download data into a company’s material tracking system and could “flag” an item so an entry was not repeated. When scanning the tags, sun glare was not a problem as compared to using bar code labels. Although further analysis is necessary, RFID did show promise of being a beneficial technology as it relates to the materials receiving process. A flowchart is provided to assist contractors and owners in selecting the appropriate RFID system.     

An RFID system for roll number identification

Improving efficiency in roll grinding process is a critical issue in the steel mill.Each roll has to be grinded to a well-defined profile and then to be measured for quality check.However,the surface conditions are inspected by using different on-line inspection probes equipped on the grinder.The roll number is a unique information which can be used to merge with a huge amount of measurement data so that the condition of each roll is fully monitored.One of the key factors that hinder the efficiency in such process is the errors and time consumption due to human intervention.In order to mitigate these issues and to realize the fully automatic grinding process,radio frequency identification technology(RFID) could be a solution and has been developed in this paper.It is well known that when an RFID tag is placed directly upon a metallic object,in the absence of a gap or a substrate,it functions rather poorly and even becomes totally dysfunctional.This limitation,in turn,poses a real barrier to the use of the RFID on metallic objects.This paper proposes a miniature RFID tag antenna design for application on roll number identification.The experimental tests show that the maximum read range of the proposed RFID tag placed on a roll is approximately 1.5m and the overall size is only 32×18×3.2 mm~3.An RFID system for roll number identification was used in a roll shop and several remarkable improvements were achieved,including the completely automatic grinding process and the error-free identification,as well as the high personnel safety operation.

Tracking the Location of Materials on Construction Job Sites

Automated tracking of materials on construction projects has the potential to both improve project performance and enable effortless derivation of project performance indicators. This paper presents an approach by which materials tagged with radio frequency identification (RFID) tags can be automatically identified and tracked on construction sites, without adding to regular site operations. Essentially, this approach leverages automatic reading of tagged materials by field supervisors or materials handling equipment that are equipped with a RFID reader and a global positioning system receiver. To assess the technical feasibility of this approach, a mathematical model has been formulated such that the job site is represented as a grid and the location of materials within the grid is determined by combining proximity reads from a discrete range. Field experiments were conducted using an off-the-shelf RFID technology, and several metrics were developed to quantify the field performance and compare it with the theoretical positional accuracy derived from the discrete formulation.

Tracking Components and Maintenance History within a Facility Utilizing Radio Frequency Identification Technology

Limitations in data transfer between maintenance workers and a central facility management (FM) system result in lower data quality, longer service process times, and ineffective capturing of component maintenance history. Radio frequency identification (RFID) technology provides an opportunity to meet the current needs for uniquely identifying facility components, storing some maintenance history information on the component, and accessing this information on-demand within a facility. There have not been any research studies that tested the performance of active ultrahigh frequency RFID technology on facility components during operations and maintenance phase repetitively over an extended period of time. The objectives of this study were to identify how RFID technology can improve current FM processes and to determine technological feasibility of using RFID within a facility repetitively on a daily basis. The writers tagged fire valves in a facility with RFID tags and conducted a longevity test for sixty consecutive days by simulating tag identification, data access, and entry in real-life conditions. The results demonstrate that current commercially available active RFID technology performs well in a building environment where metallic objects and different obstructions are present. The observed reading distances were approximately half of the reading range expected in open air provided that there are not any massive obstructions between the reader and the tag.
