WHAT IS RFID ?

Radio Frequency Identification

A micro-chip in a label/card used to transmit data when it is exposed to radio waves.

HISTORY OF RFID

• RFID technology was first introduced in World War II.

• UK developed IFF to detect their own aircrafts.

• In 1960 started using in commercial sector.

• By 1970 – Vehicle tracking and refined for smart tolls

Typical components of RFID system

• RFID tags and antenna • RFID reader

• RFID middleware

• RFID application software system

RFID tags and antenna - small semiconductor chip with integrated antenna.

RFID reader - Responsible for data acquisition and receiving information, read the tag and send information into a computer.

RFID middleware - supports the discovery, backup, supervision and management from the reader, it also provides data collection, filtering and grouping mechanism.

RFID application software system - effectively control the reader to read and write information from the electronic tags, and manage the collected information.

Types of tags:ActivePassive Semi-passive

Distinctive features of RFIDRFID reader can read multiple RFID tags without contact or line-of-sight at the same time, saving time.

Durability - RFID tags can be repeatedly read hundreds of thousands or even millions of times.

Large data memory capacity - RFID has ample memory space which allows it to save much information which will be even up to tremendous megabytes.

Affordable technology - The cost of RFID’s components is becoming cheaper and cheaper, so RFID has been used widely in many industries.

Penetrability - Because RFID transmits information through radio waves, nearly no barriers can hinder its penetration.

Contamination resistance - RFID tags have a strong resistance for water, oil, chemicals and other substance’s. Information is stored in the chip which is protected by the shell to make sure the information away from damage and defacement.

Volume miniaturization and shape diversification - The application of RFID technology doesn’t restricted by the size and shape of tags.

APPLICATION OF RFID IN CONSTRUCTIONConstruction Time and Schedule ManagementConstruction Quality ManagementConstruction Supply Chain ManagementConstruction safe ManagementConstruction Document ManagementConstruction waste Management

Construction Time and Schedule ManagementConstruction project cycle is long and time sensitive .

Schedule delay during construction has a great impact on the project investment and returns.

RFID and 4D CAD integrated process management system enables accurate logistics and progress management and leading to the reduction of material loss and schedule overrun

Construction Quality Management

Concrete and Asphalt Pavement Maturity Monitoring

Inserting RFID tags inside concrete specimens does not influence the strength of the concrete.

Early formwork removal, identification of weak spots in the concrete, hydration rate, remedial action warning etc.

• Quality Inspection and Management

For better enhancing construction quality inspection and management, a RFID-based quality management application called RFID-QIM.(RFID based quality inspection & management).

Integrates web and RFID technology to automatically collect data for concrete specimen inspection and management.

• Building maintenance

RFID technology is a promising method to effectively improve maintenance efficiency.

Web-based RFID technology building maintenance systemData management moduleStatistical module &Scheduling moduleCan automatically identify equipment and facility ID in real-time without contact or line-of-sight

Construction Supply Chain ManagementMaterial is a critical in construction industry and can make

significant contributions to reduce the cost of the project.

Manual material supply chains result in time and labor –intensive, late deliveries, unreliable, missing materials.

Material information can be stored in RFID tags, and the locations of materials can be tracked by combining RFID with GIS and GPS.

Improve production efficiency and the elimination of missing panels and incorrect shipments.

Construction safe ManagementHazardous material.

RFID tags can be attached to hazardous materials so as to keep workers informed of the type and location of hazardous materials and prevent accidental contact on site

Underground project.Improve safety conditions in underground project such

as tunneling and subway project, for instance, monitoring workers, the operating status and indicators, groundwater levels, water pressure to protect the workers and equipment operating around them

Fall protection and prevention.

Falls are the leading cause of fatalities .

An alert system developed with RFID technology can give a warning when workers are approaching a guardrail or a nearby boundary with a steep change in elevation,

Collision accidents with heavy equipment.

To alert workers with the operating heavy equipment to prevent the number of fatalities and accidents resulting from persons coming in contact with machinery in construction industry, such as hydraulic excavators and cranes.

Project fire

Used in building evacuation system for getting workers location information which can rapidly calculate the most reliable evacuation routes when building fire happens and send the information to mobile phone to reduce the number of casualties.

Construction Document ManagementConstruction project is information-intensive

Effective management of a large proportion of construction documents depends on the ability to extract and integrate information from different kinds of documents

It is essential and necessary to capture, archive and handle construction information rapidly and accurately in construction sites to support project management.

Construction waste ManagementIn many large cities, waste poses a very serious

environmental problem ,Especially C&D waste.

RFID tags can be attached to the waste items which will be respectively treated according to their different types.

Recycling companies can get the information available online to select the waste items that they are interested in.

DISADVANTAGES OF RFIDMore than one tag can respond at the same time.

Possibility of unauthorized reading.

Tags are application specific.

RFID tags are usually larger than barcodes.

RFID are often more expensive than barcode systems.
