HIGHLIGHTS OF OUR M&E SERVICES

Engineering, Procurement and Constructionof Mechanical & Electrical MEP ProjectsEPC stands for Engineering, Procurement, and

Construction and is a prominent form of

contracting agreement in the construction

industry. The engineering and construction

contractor will carry out the detailed engineer-

ing design of the project, procure all the equip-

ment and materials necessary, and then

construct to deliver a functioning facility or

asset to their clients. Companies that deliver

EPC Projects are commonly referred to as EPC

Contractors. The EPC phase of the project is

also known as the Execution phase which

normally follows what is known as a FEED or

Front End Engineering Design phase.

The FEED is a basic engineering design used as

the basis for the EPC phase. The FEED can be

divided into separate packages covering differ-

ent portions of the project.

The FEED packages are used as the basis for

bidding on when the client offers the EPC work

to the market, normally the EPC Contractor has

to execute and deliver the project within an

agreed time and budget, commonly known as a

Lump Sum Turn Key (LSTK) Contract. An EPC

LSTK Contract places the risk for schedule and

budget on the EPC Contractor.

Heating, Ventilation & Air-conditioningServices (HVAC)HVAC (heating, ventilating/ventilation, and air

conditioning is the technology of indoor and

vehicular environmental comfort. Its goal is to

provide thermal comfort and acceptable

indoor air quality. HVAC system design is a sub

discipline of mechanical engineering, based on

the principles of thermodynamics, fluid

mechanics, and heat transfer. Refrigeration is

sometimes added to the field's abbreviation as

HVAC&R or HVACR, or ventilating is dropped as

in HACR (such as the designation of HACR-rat-

ed circuit breakers).

HVAC is an important part of residential struc-

tures such as single family homes, apartment

buildings, hotels and senior living facilities,

medium to large industrial

and office buildings such as skyscrapers and

hospitals, onboard vessels, and in marine

environments, where safe and healthy building

conditions are regulated with respect to

temperature and humidity, using fresh air

from outdoors.Ventilating or ventilation (the V

in HVAC) is the process of exchanging or

replacing air in any space to provide high

indoor air quality which involves temperature

control, oxygen replenishment, and removal of

moisture, odors, smoke, heat, dust, airborne

bacteria, carbon dioxide, and other gases.

Ventilation removes unpleasant smells and

excessive moisture, introduces outside air,

keeps interior building air circulating, and

prevents stagnation of the interior air.

07

District Cooling System

District cooling means the centralized produc-

tion and distribution of cooling energy. Chilled

water is delivered via an underground insulat-

ed pipeline to office, industrial and residential

buildings to cool the indoor air of the buildings

within a district. Specially designed units in

each building then use this water to lower the

temperature of air passing through the build-

ing's air conditioning system.

The output of one cooling plant is enough to

meet the cooling-energy demand of dozens of

buildings.

District cooling can be run on electricity or

natural gas, and can use either regular water or

seawater. Along with electricity and water,

district cooling constitute a new form of energy

service. District cooling is measured in refriger-

ation ton which is equivalent to 12000 BTU's

per hour. Refrigeration Ton is the unit measure

for the amount of heat removed. Refrigeration

Ton is defined as the heat absorbed by one ton

of ice (2000 pounds) causing it to melt

completely by the end of one day (24 hours).

08

The main function of an electrical power distri-

bution system is to provide power to individual

consumer premises. Distribution of electric

power to different consumers is done with

much low voltage level. Distribution of electric

power is done by distribution networks. Distri-

bution networks consist of following main

parts:-

• Distribution substation,

• Primary distribution feeder,

• Distribution Transformer,

• Distributors,

• Service mains

The transmitted electric power is stepped

down is substations, for primary distribution

purpose. Now these stepped down electric

power is fed to the distribution transformer

through primary distribution feeders. Over-

head primary distribution feeders are support-

ed by mainly supporting iron pole (preferably

rail pole). The conductors are strand aluminum

conductors and they are mounted on the arms

of the pole by means of pin insulators. Some

times in congested places, underground cables

may also be used for primary distribution

purposes.

Plumbing & Drainage System

Plumbing is any system that conveys fluids for

a wide range of applications. Heating and

cooling, waste removal, and potable water

delivery are among the most common uses for

plumbing however plumbing's not limited to

these applications. Plumbing utilizes pipes,

valves, plumbing fixtures, tanks, and other

apparatuses to convey fluids. Trades that work

with plumbing such as boilermakers, plumb-

ers, and pipefitters are referred to the plumb-

ing trade. In the Developed world plumbing

infrastructure is critical for public health and

sanitation.

Drainage system is excessively wet land area

with a network of channels, drains,

and hydraulic engineering and other structures

that provide for drainage.

The main elements of a drainage system are

the regulating, protective, and conducting

networks, which makeup the drainage

network; the water relief system, that is, the

body of water, such as river, lake, or sea, receiv-

ing the drained water; the hydraulic engineer-

ing structures (over falls, channel openings,

sluices, manholes, and pumping stations); the

road network (roads, bridges, culverts, and

livestock crossings); and the operating struc-

tures (benchmarks, observation shafts).

A fire sprinkler system is an active fire protec-

tion method, consisting of a water supply

system, providing adequate pressure and

flowrate to a water distribution piping system,

onto which fire sprinklers are connected.

Although historically only used in factories and

large commercial buildings, systems for homes

and small buildings are now available at a

cost-effective price. Fire sprinkler systems are

extensively used worldwide, with over 40

million sprinkler heads fitted each year. In

buildings completely protected by fire sprinkler

systems, over 96% of fires were controlled by

fire sprinklers alone.

Fire hose reels are located at strategic places in

buildings to provide a reasonably accessible

and controlled supply of water for fire extin-

guishing. Fire hose reel systems consist of

pumps, pipes, water supply and hose reels

located strategically in a building, ensuring

proper coverage of water to combat a fire. The

system is manually operated and activated by

opening a valve enabling the water to flow into

the hose that is typically 30 meters away. The

system pressure loss will activate the pump

ensuring adequate water flow and pressure to

provide a water jet of typically a minimum of 10

meter from the nozzle.

Fire Protection & Alarm System

A fire alarm system is number of devices work-

ing together to detect and warn people through

visual and audio appliances when smoke, fire,

carbon monoxide or other emergencies are

present. These alarms may be activated from

smoke detectors, and heat detectors. Alarms

can be either motorized bells or wall mount-

able sounders or horns. They can also be

speaker strobes which sound an alarm,

followed by a voice evacuation message which

warn people inside the building not to use the

elevators. They may also be activated via

manual fire alarm activation devices such as

manual call points or pull stations. Fire alarm

sounders can be set to certain frequencies and

different tones including low, medium and

high, depending on the country and manufac

turer of the device. Most fire alarm systems in

Europe sound like a siren with alternating

frequencies. Fire alarm sounders in the United

States can be either continuous or set to differ

ent codes such as Code 3. Fire alarm warning

devices can also be set to different volume

levels. Smaller buildings may have the alarm

set to a lower volume and larger buildings may

have alarms set to a higher level.

12

Ventilation systems for car parks, loading bays

and service areas are needed to achieve two

objectives. Day-to-day ventilation is needed to

control buildup of vehicle exhaust fumes or

spilled fuel when the facility is in general use.

Acceptable day-to-day air quality is maintained

by removing exhaust gases produced by

vehicles and by ensuring that there are no

pockets of stagnant air. Smoke ventilation is

needed to provide a means of clearing smoke

from the car park during and after a fire.

This will limit smoke temperatures and struc-

tural damage and inhibit smoke spread

between floors. Smoke ventilation systems

may be designed in addition to provide clear

smoke-free access for fire fighters to tackle the

seat of the fire or to protect means of escape

from the car park. These systems are more

complex and exceed the requirements of the

Building Regulations. They are generally used

as compensating features when other require-

ments of the regulations are not met.

Mechanical Car Park Ventilation System

13

A kitchen hood, extractor hood, or range hood is

a device containing a mechanical fan that hangs

above the stove or cooktop in the kitchen. It

removes airborne grease, combustion products,

fumes, smoke, odors, heat, and steam from the

air by evacuation of the air and filtration. In com

mercial kitchens exhaust hoods are often used

in combination with fire suppression devices so

that fumes from a grease fire are properly

vented and the fire is put out quickly. Commer-

cial vent hoods may also be

combined with a fresh air fan that draws in

exterior air, circulating it with the cooking

fumes, which is then drawn out by the hood.

In most exhaust hoods, a filtration system

removes grease (the grease trap) and other

particles. Although many vent hoods exhaust

air to the outside, some recirculate the air to

the kitchen. In a recirculating system, filters

may be used to remove odors in addition to the

grease.

Kitchen Hood And Exhaust System

16

According to the National Fire Protection

Association, the process of evacuating some of

today’s largest high-rise buildings may take

upwards of two hours. This is by far the most

compelling argument for effective smoke

control in building stairwells. Pressurized

staircases keep exit routes smoke free in the

event of a fire, lending precious minutes to

building occupants during an evacuation. The

pressures specified to keep a stairwell pressure

positive vary by code.

However, the universal goal is to restrain

smoke but still allow the opening of doors in

the stairwell shaft. This is where stairwell

pressurization control gets tricky. In the event

of a fire and a subsequent evacuation there will

be intermittent losses of pressure inside the

stairwell as stairwell doors open. An effective

pressurization system will have supply air fans

with sufficient capacity to provide pressuriza-

tion to prevent smoke entry when doors are

open.

FM-200 is a clean, colorless, and environmen-

tally friendly fire suppression agent that is

electrically non-conductive and safe for

humans. It extinguishes flames primarily

through heat absorption, leaving no residue,

thus minimizing downtime after a fire and

making FM-200 suppression systems accepted

and respected worldwide with over one

hundred thousand installations in more than

seventy countries. A deluge fire sprinkler

system is similar to a pre-action system except

the sprinkler heads are open and the pipe is

not pressurized with air. Deluge systems are

connected to a water supply through a deluge

valve that is opened by the operation of a

smoke or heat detection system. The detection

system is installed in the same area as the

sprinklers. When the detection system is

activated water discharges through all of the

sprinkler heads in the system. Deluge systems

are used in places that are considered high

hazard areas such as power plants, aircraft

hangars and chemical storage or processing

facilities.

FM200 And Deluge System

CCTV (closed-circuit television) is a TV system in

which signals are not publicly distributed but

are monitored, primarily for surveillance and

security purposes. CCTV relies on strategic

placement of cameras and private observation

of the camera's input on monitors. The system

is called "closed-circuit" because the cameras,

monitors and/or video recorders communicate

across a proprietary coaxial cable run or

wireless communication link.

Closed Circuit TV System (CCTV)

Simply defined, the term "access control"

describes any technique used to control

passage into or out of any area. The standard

lock that uses a brass key may be thought of as

a simple form of an "access control system".

Over the years, access control systems have

become more and more sophisticated. Today,

the term "access control system" most often

refers to a computer-based, electronic card

access control system. The electronic card

access control system uses a special "access

card",

rather than a brass key, to permit access into

the secured area. Access control systems are

most commonly used to control entry into

exterior doors of buildings. Access control

systems may also be used to control access

into certain areas located within the interior of

buildings. The purpose of an access control

system is to provide quick, convenient access

to those persons who are authorized, while at

the same time, restricting access to unautho-

rized people.

Access Control System

21

A public address system (PA system) is an

electronic sound amplification and distribution

system with a microphone, amplifier and

loudspeakers, used to allow a person to

address a large public, for example for

announcements of movements at large and

noisy air and rail terminals or at a sports stadi-

um. The term is also used for systems which

may additionally have a mixing console, and

amplifiers and loudspeakers suitable for music

as well as speech, used to reinforce a sound

source, such as recorded music or a person

giving a speech or distributing the sound

throughout a venue or building.Simple PA

systems are often used in small venues such as

school auditoriums, churches, and small bars.

PA systems with many speakers are widely

used to make announcements in public,

institutional and commercial buildings and

locations. Intercom systems, installed in many

buildings, have microphones in many rooms

allowing the occupants to respond to

announcements. Sound reinforcement

systems and PA systems may use some similar

components, but with differing application,

although the distinction between the two is not

clear-cut. Sound reinforcement systems are for

live music or performance, whereas PA

systems are primarily for reproduction of

speech.

Public Address System

22

Video surveillance, is the use of video cameras

to transmit a signal to a specific place, on a

limited set of monitors. It differs from broad-

cast television in that the signal is not openly

transmitted, though it may employ point to

point (P2P), point to multipoint (P2MP),

or mesh wireless links. Though almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that may need moni-toring such as banks, casinos, airports, military installations, and convenience stores.

Video Surveillance System

23

A building management system (BMS), other-

wise known as a building automation system

(BAS), is a computer-based control system

installed in buildings that controls & monitors

the building’s mechanical & electrical equip-

ment such as ventilation, lighting, power

systems, fire systems, & security systems. A

BMS consists of software & hardware; the

software program, usually configured in a

hierarchical manner, can be proprietary, using

such protocols as C-Bus, Profibus, and so on.

Vendors are also producing BMSs that

integrate using Internet protocols & open

standards such as DeviceNet, SOAP, XML,

BACnet, LonWorks & Modbus. Building

management systems are most commonly

implemented in large projects with extensive

mechanical, HVAC, electrical systems. Systems

linked to a BMS typically represent 40% of a

building's energy usage; if lighting is included,

this number approaches to 70%. BMS systems

are a critical component to managing energy

demand.

Building Management System (BMS)

24

Home automation is the residential extension

of building automation and involves the control

and automation of lighting, heating, ventilation,

air conditioning (HVAC), appliances, and securi-

ty. Modern systems generally consist of switch-

es and

sensors connected to a central hub sometimes

called a "gateway" from which the system is

controlled with a user interface that is interact-

ed either with a wall-mounted terminal, mobile

phone software, tablet computer or a web

interface.

Home Automation System (HAS)

25

The system manages different scenarios in

each guest room, including welcome, living and

sleeping settings. Lighting, temperature and

curtains can be controlled to suit the activity of

the occupant. Settings can either be adjusted in

the room by the guest or centrally via the hotel

management system.

26

In order to offer the best possible space utiliza-

tion, and to accommodate the potentially rapid

expansion of new IT equipment, modern data

centers have implemented a high-density

model, based primarily on blade server

technology. This model requires a higher

power supply density, and can thereby create

more significant problems with heat dissipa-

tion. In order to address these issues,

round-the-clock air conditioning is sometimes

deployed as a cooling system solution.

However, the expense of using this method for

data center cooling can end up accounting for

up to 45% of the total electricity expenses

incurred by the data center. With this in mind,

heat dissipation and electricity expenses are

important indices against which operational

expenditures of the data center can be

measured. Specialized forms of air condition-

ing and temperature control have been devel-

oped to cater to the unique cooling system

needs of contemporary data centers.

27

Many facilities management professionals use

a combination of tools including email, spread-

sheets, and homegrown software to manage

the maintenance and operation of facilities,

space, and associated resources. Facilities

requests and space planning requests are

usually submitted and addressed via email and

phone with little to no accountability or trans-

parency into the work being requested and

performed. These methods may have been

sufficient when facilities management focused

on tactical operations,

but today’s enterprise relies on facilities

managers to address corporate goals for

growth, sustainability, business continuity,

operational efficiency, staff productivity, and

cost control. In this environment, effective

facilities management requires a service

management system that frees the facilities

manager from reactive, day-today operations

and delivers the ability to understand,

measure, and report on the performance of

facilities services and its impact on the

business.
