QUALITY MANAGEMENT SYSTEM
What is a Quality Management System?
A quality management system is a way of defining how an organization
can meet the requirements of its customers and other stakeholders
affected by its work. Other ISO standards look at other types of
management systems, such as ISO 14001 for environmental
management or the upcoming ISO 45001 for occupational health and
safety management.
ISO 9001 is based on the idea of continual improvement. It is designed
to be flexible enough for use by many different types of organization, so
does not specify what the objectives relating to “ quality ” or “ meeting
customer needs ” should be. Instead, it requires organizations to define
these objectives themselves and continually improve their processes in
order to reach them. Once these targets have been attained , they must be
reassessed… in a quest for Continual improvement.
A good quality management system can bring benefits
to organizations of all sizes and all sectors.
What benefits will it bring to my business or
organization?
Implementing a quality management system will help you:
• Assess the overall context of your organization to define who is
affected by your work and what they expect from you. This will enable

21
you to clearly state your objectives and identify new business
opportunities.
• Put your customers first, making sure you consistently meet their
needs and enhance their satisfaction. This can lead to repeat custom, new
clients and increased business for your organization.
• Work in a more efficient way as all your processes Will be aligned
and understood by everyone in the business or organization. This
increases productivity and efficiency, bringing internal costs down.
• Meet the necessary statutory and regulatory requirements.
• Expand into new markets, as some sectors and clients require ISO
9001 before doing business.
• Identify and address the risks associated with your organization .
QUALITY MANAGEMENT PRINCIPLES
ISO 9001 BUILDS ON SEVEN QUALITY MANAGEMENT
PRINCIPLES
One of the definitions of a “principle” is that it is a basic belief, theory
or rule that has a major influence on the way in which something is
done. “Quality management principles” are a set of fundamental beliefs,
norms, rules and values that are accepted as true and can be used as a
basis for quality management. The QMPs can be used as a foundation to
guide an organization’s performance improvement. They were
developed and updated by international experts of ISO/TC 176, which is
responsible for developing and maintaining ISO’s quality management
standards.

22
The seven quality management principles are:
QMP 1 - Customer focus
QMP 2 - Leadership
QMP 3 - Engagement of people
QMP 4 - Process approach
QMP 5 - Improvement
QMP 6 - Evidence-based decision making
QMP 7 - Relationship Management .
The QMPs can be used as a foundation to guide an organization’s
performance improvement. They were developed and updated by
international experts of ISO/TC 176, which is responsible for developing
and maintaining ISO’s quality management standards.

MECHANICAL WORK FOR 10
UNDERGROUND STATIONS FOR DMRC
LAYOUT OF DELHI METRO STATION

27
ANCILARY BUILDING : It is on the ground level. This building
consist of air conditioning plants, fire pumps, water distribution
equipment, diesel generators for power backup and associated
electrical panels.
CONCOURSE : It is the first sector of underground level. It is the
sector where tickets are sold. It also contains helpdesk and
control room i.e., telecommunication room, UPS room, E.P.R ,
DB rooms and access machine etc.
PLATEFORM: It is the second sector of underground level. It is
the sector where the passengers board the train. It also contain
rooms like Auxiliary Sub Station (ASS), sewage and seepage
panel room, the rooms for treatment of sewage and seepage
water and DB rooms.
UNDERCROFT: It is the third and last sector of underground
level. It is the sector where all the cables and wires are present.
These wires are those which are used for signaling, cables
connected to LT and HT panels for power distribution.

28
SCOPE OF MECHANICAL WORKS
FIRE FIGHTING SYSTEM;
 HYDRANT SYSTEM- It’s a fixed manual fire protection
system using pipe filled with pressurized water, supplied
from dependable source. The Valves are normally closed,
once the initiation of hydrants is required user attaches a
hose to the fire hydrant, then opens a valve on the hydrant
to provide a powerful flow of water.
SEQUENCE OF OPERATION FOR HYDRANT AND
HOSE REEL SYSTEM
 SPRINKLER SYSTEM- Used in DMRC UG:
WET PIPE SYSTEM: It consist of network of piping
containing water under pressure. Automatic sprinklers are
connected to the piping such that each sprinkler protects an
assigned building area. The application of heat to any
sprinkler will cause that single sprinkler to operate,
permitting water to discharge over its area of protection.

29
 DELUGE SYSTEM - It is one that does not use automatic
sprinklers, but rather opens sprinklers. A special deluge
valve holds back the water from the piping, and is activated
by a separate fire detection system. When activated, the
deluge valve admits water to the piping network, and water
flows simultaneously from all of the open sprinklers. Deluge
systems are used for protection against rapidly spreading,
high hazard fires.
 WATER BASED SYSTEM
MAIN COMPONENT OF PUMP ROOM
 Water Storage Tanks at Ancillary Building Terrace.
 Vortex Plate
 Main suction line
 Common Suction Header.
 Individual pump suction line

31
 HOSE REEL:- Fire hose reels are basically manually
operated first aid fire extinguishant. Fire hose reels are
located in the facility to fight the fire in the initial stages until
authorized personal or fire department authority take over.
THERE ARE BASICALLY TWO DIFFERENT TYPES OF
FIRE HOSE REELS.
 Manually operated fire hose reel
 Automatically operated fire hose reel.

33
MAIN COMPONENTS USED IN
MECHANICAL WORKS
PUMP SETS :-
These are the devices used in the system to support the supply
& demand of Water in Case of Fire/Emergency conditions.
 Separate pump sets for Hydrant system & sprinkler system
 Each Set = 1 Main fire pump + 1 Stand by fire pump + 1
Jockey Pump
 A fire pump is tested and listed for its use specifically for fire
service by a third-party testing and listing agency, such as
UL or FM Global
 The main code that governs fire pump installations is the
National Fire Protection( Association's NFPA 20 Standard for
the Installation of Stationary Fire Pumps for Fire Protection )

34
VALVES
Regardless of type, all valves have the following basic parts: the
body, bonnet, trim (internal elements), actuator, and packing.
The basic parts of a valve are illustrated in the image:
