ABSTRACT

The report has account of all the works carried out as discussed in detail to provide concepts for
the mechanical, electrical and plumbing. It has five chapters that describes the design of lighting
calculation, the electrical wiring, plumbing systems, fire detection and fighting systems for the
proposed residential apartments at Lugala.

The work was done with the objective of designing the plumbing system of the building and the
drainage system of storm water and waste water and developing a systematic drawing of the
building.

The electrical design for lighting and power is decribed. Lighting was designed using the lumen
method and power design followed electrical demand load of the project and the results were
indicated in the drawings attached. Different sanitary appliances and fittings subjected for
approval to client have been described during the design. The plumbing works were done in
accordance with the Water Supply Design Manual, while electrical works were done with
reference to the Institution of Electrical Engineers’ Regulations.

In conclusion, the building will be connected to NWSC main supply through the metered
connection feeding water in tanks of 2000 liters through DN32mm PPR PN16 riser pipes/
streaming from ducts as shown in the drawings. Sanitary appliance drainage will be provided to
the stacks via pipes in the ducts. For incoming main power supply, it is proposed that it is
metered with incoming UMEME service cable through a 400 amperes TPN MCCD breaker and
outgoing load cable.

We recommend personal safety for all workers and all works should be done inaccordance to the
design content and manuals with building regulations inclusive. Therefore it is our greatest desire
that the client implements the proposed Residential apartment at Lugala for better
accommodation facilities.

 CHAPTER TWO: ELECTRICITY AND LIGHTING

2.1 Introduction.

This chapter shows procedures that will be followed in the design for lighting, small power and
lightning, and there after the production of the Lighting layout, Small power layout and Schematic
drawing Supply of Electricity.

Electricity is produced at power generating stations say at the Owen falls Dam (power station) of
about 200meggawatts potential in three-phase supply. Thereafter it is processed by step-up
transformers to 132, 275 or 400kV before connecting to the national grid. Power to large towns and
cities by overhead lines at 132 kV or 33 kV where it is transformed to an 11 kV underground
supply to sub-stations. From these sub-stations the supply is again transformed to the lower
potential of 400 volts, three-phase supply and 240 volts, single-phase supply for general
distribution. The supply for domestic use, is by an underground ring circuit from local substations.
Supplies to factories and other large buildings or complexes are taken from the 132 or 33 kV main
supply. Larger buildings and developments will require their own transformer, which normally
features a deltastar connection to provide a four-wire, three-phase supply to the building

2.2 Design of the Lighting System.

The Lighting circuits that were used were one-way and two-way and some with an intermediate
switch depending on the area which is to receive the bulbs. Bulbs with different capacities, lumen
and switches will be selected for different purposes for the comfort of occupants.

Procedure for the Design of the Lighting System

The first step was to determine the number of bulbs. Here the first thing, was to calculate for the
area to be illuminated. The areas were obtained with an aid of AutoCAD tools and the values are
shown in the next chapter.

Next step was to calculate the lumen requirement for each space or room to receive the light.
Lumens are the unit describing the amount of light energy seen by the human eye that is given out
by the lighting bulb. The table below shows the lumen requirement for each room that was used in
the calculations. 1 lux = 1 lumen / sq meter = 0.0001 phot = 0.0929 foot candle (ftcd, fcd)
Example;

Lumens= Area of room x lumen requirements

The third step was to calculate the number of lights required. From The lumen method of lighting
design the

3
number of bulbs were then calculated; 𝑁 = (� × ��) ÷ (F × U ×

M)

or N = (� 𝒙 𝑨 )/ � 𝒙 � 𝒙 𝑴� 𝒙 𝑼�

Where;

N - Is the number of luminaires required,- Is the required illuminance (lux),

A - Is the area of the room to be lit; n - Is the number of lamps per luminaire,

- Is the lamp lumen output (lumens),

MF - Is known as the maintenance factor, which is a combination of three factors,

UF - Is the utilization factor and is a function of the luminaire properties and room geometry.

The lumen differs from manufacturer to manufacturer and from national optical astronomy
observatory (NOAO) and other bodies the wattage and lumens relationship below can be used to
estimate the lumen for the following types of bulbs.

2.2.1 Utilisation Factor (UF)

This is determined by approximating the number of hours expected for the appliance to be in use
divided by the time of the number of hours of the day. The UF used most of all the lamps will be
0.8 for proper efficiency of most lamps.

5
2.2.2 Maintenance Factor (MF)

The maintenance factor is a value designed to account for the reduction in light output from a
lighting system due to the ageing of the lamps and the accumulation of dirt and dust on the light
fittings and room surfaces. The value used for the maintenance factor is between 0-1. We chose to
use a maintenance factor of 0.9 for proper efficiency of the lamp.

The next step was to size the appropriate switch for the lighting. Here the first thing was to
calculate the total power in a particular circuit followed by estimating the voltage drop due to
length of the cable of the circuit. The value of the current can be calculated from = P/V , the value
of the current can then be used to determine the rating of the switch.

The third step will be determination of appropriate size of cable for lighting purposes which is
discussed in section 2.4 (small power design). The last step was to now prepare the lighting
drawing. This was done with an aid of the software. Here AutoCAD was used in the preparation of
the drawing.

2.3 Design of small power

The design of small power includes the design of power sockets for appliances such as water
heater, socket ring main, cooker, and shower. To minimize costs and over load the circuit has been
designed to serve an unlimited number of sockets with a separate circuit were also provided solely
for the kitchen, as this contains relatively high rated appliances. The following provision guidance
on the minimum provision for power sockets in was used (British standards).

Table 0-3: Minimum number of Power sockets needed

Dining room 4
Single Bedrooms 4
Bathroom 1- Double Insulated Shaver Socket

Every ring circuit for every block has been protected by a 30 amp mcb, and every socket is rated at
13 amps. The following Guidance for diversity were used in our design:

The appropriate size for cables for small power and lighting was designed using the following
steps;

 iii Check that the voltage drop is not greater than 4%.

The tables below were used in the selecting then cable size and the current flowing in their paths.

2.4 Lightning Arresting System Design

The lightning system we designed is an external system, BS EN/IEC 62305-2 suggests two types
i.e. The isolated and the non-isolated. Our design is an isolated system which consists of an air
termination system, down conductor system and the earth termination system. These in practice are
joined together using appropriate lightning protection components complying with BS EN 62305.
This ensures efficient current discharge from the structure in the event of a lightning strike

2.5 Components of a schematic drawing

2.5.1 Meter

This measures the amount of current entering into the system. All components up to and including
the meter is the property of the supply authority which is UMEME in Uganda.

2.5.2 Transformer

This steps down or steps up the power depending on the load requirement of the structure An oil
type transformer is recommended for the multipurpose building. An oil type transformer uses
transformer oil to cool down the temperature. It is a highly refined mineral oil that is stable at high
temperatures and has excellent electrical insulating properties. Advantages of oil insulated
transformer are small size, low first cost, low losses, long life, low noise level and etc.

Figure 0-1: Oil Insulated Transformer

2.5.3 Standby generator

It is a backup electrical system that operates automatically within seconds of a utility off shading. It
has automatic change over switch which senses the power loss, commands the generator to start
and then transfer electrical loads to the generator.

2.5.4 Residual current device.

It is a device that instantly breaks an electric circuit to prevent serious harm from an ongoing
electric shock. They are used for protection from earth leakages.

2.5.5 Miniature Circuit breaker.

This is a device that cuts off electrical power if wiring is overloaded with current. They help
prevent fires that can result when wires are overloaded with electricity. In other words, it’s for
completing and breaking the current flowing in the circuit.

2.5.6 Consumer Unit

A consumer unit is the electrical device used to distribute power throughout a domestic dwelling.
This unit contains a two-pole switch isolator for the phase/live and neutral supply cables and three
bar for the live, neutral and earth terminals. The live bar will be provided with several fuse ways or

9
a miniature circuit breaker to protect the individual circuits from overload. Each fuse will be
selected with a rating in accordance with the circuit functions.

2.5.7 Earthing

Earthing system is circuitry which connects parts of the electric circuit with the ground, thus
defining the electric potential of the conductors relative to the Earth's conductive surface.
Furthermore, it transfers access current to the ground . The purpose of the earthing of the
multipurpose building is basically;

• To Protect the building from lightening

• To Protect occupants from electric shock tendencies

• To provide main equipotential bonding: Here water installation pipes, gas pipes; exposed
metallic surfaces were earthed to prevent shock

• To Provide supplementary equipotential bonding: This involved connecting together

conductive parts of electrical items and non-electrical items to earthing in order to prevent
occurrence of dangerous voltage between them under earth fault conditions.

Water supply Total Head

design There are three principal components to total head of
manual importance when specifying a pump

• Static head
• Dynamic head
• Pressure head
Static head is the vertical distance between level of water at
the river/intake and the delivery water level at the treatment
plant, dynamic head is due to friction losses in the system
and the pressure head is the difference between the
atmospheric pressure at the surfaces of water at the river and
the water storage tank.

 CHAPTER THREE: MAXIMUM LOAD DEMAND

3.1 Introduction

This chapter presents the computation of the maximum load demand for the proposed construction
of residential apartments at Lugala. Described below is the adopted methodology or formulae for
computation and the corresponding calculations.

3.2 Calculating Maximum Load Demand

The estimate of the maximum load demand was for determining the specifications of
thewiring equipment such as the cables and accessories and subsequently for preparing the
electrical installation plans.

According to clause 311 of MS IEC 60364 Part 1, the maximum demand for each circuit
while ensuring an economic and reliable design within the permitted voltage drop limits was
determined. Diversity factors were taken into account.

The maximum current demand calculations for each circuit were prepared. These details
showed the current requirements, in amperes, for each phase and also assisted in determining
the cable sizes.

Circuit Ratings were based on BS EN 60898:, Table below shows the design requirements
for Circuit over protection that were applied;

Formula used I=P/V, Amps = Power / Voltage

A simple means of designing lighting systems was achieved by means of the lumen method;
this was a simplified design approach to enable the designer to achieve an even light
distribution in spaces of reasonably simple geometry (i.e. rectangular).

The basis of the lumen method is the following equation:

E ×A
𝑁=
n × F × MF × UF

Where:

N - Is the number of luminaires required;

E - Is the required illuminance (lux); A - Is the area of

the room to be lit; n - Is the number of lamps per
luminaire;
F - Is the lamp lumen output (lumens);

MF - Is known as the maintenance factor, which is a combination of three factors;

UF - Is the utilization and is a function of the luminaire properties and room geometry.
 CHAPTER FOUR: CONCLUSION CHALLENGES AND
RECOMMENDAIONS

4.1 Conclusion

4.2 Challenges

Although the exercise was successful, there were a few challenges along the way.

• The project demanded full time of concentration in order to have a successful

project despite the fact that there was other course units to attend to.

• Limited finances: the exercise was financially demanding most of us were purely
students who had no source of income.

• Limited knowledge in software use: some of the software’s we needed to use at

some point did not know on how to use them. This made it a bit challenging for us
but we thank our supervisors and some of our colleagues from other groups for
helping us learn these applications like Auto cad, Civil 3D and others.

4.3 Delimitations.

• The project was time bound and as such finishing it in limited time was a
constraint.

• Consultations to gather more knowledge on software were a tedious process as the

individuals with such knowledge were not readily available to us.

4.4 Recommendations

• This exercise should be emphasized since they train the students hands on and
become independent Engineers of tomorrow.

• Lectures should be followed up to ensure that they are delivering the content as it
should be to the students. This would result in students having the necessary skills
needed to execute the project with minimum hardship at the time of embarking on
the project.
