3. RFID TECHNOLOGY
WHAT IS RFID ?
Radio Frequency Identification
A micro-chip in a label/card used to transmit
data when it is exposed to radio waves.

6. 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
7. Typical components of RFID system
• RFID tags and antenna
• RFID reader
• RFID middleware
• RFID application software system
8. 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.
11. Distinctive features of RFID
RFID reader can read multiple RFID tags without
contact or line-of-sight at the same time, saving time.
12. 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.
13. 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.
14. APPLICATION OF RFID IN
CONSTRUCTION
Construction Time and Schedule Management
Construction Quality Management
Construction Supply Chain Management
Construction safe Management
Construction Document Management
Construction waste Management
15. Construction Time and Schedule
Management
Construction 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

17. 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.
18. • 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.
19.
20. • Building maintenance
RFID technology is a promising method to
effectively improve maintenance efficiency.
Web-based RFID technology building maintenance
system
Data management module
Statistical module &
Scheduling module
Can automatically identify equipment and facility
ID in real-time without contact or line-of-sight
21. Construction Supply Chain
Management
Material 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.

25. Construction safe Management
Hazardous 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
26. 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,
27. 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.
28. 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.
29.
30. Construction Document
Management
Construction 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.
31.
32. Construction waste Management
In 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.
33.
34. DISADVANTAGES OF RFID
More 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.
