1. a. First Consideration
Budget
 One should start construction with a budget for
instance, you could a budget based on an area that
you have available for construction say @ Rs. 500/- per
sqft poor planning needs to major over run tropically to
major expenses cost of land and cost of construction.
Selection of a Plot
 The critical decision before starting construction is to
decide the location and size of plot.
Size of the Plot
Size of the plot should be depending on size of the
building and the length-breadth ration of the plot should
not exceed 1:2.
Legal Aspect
 Utmost care should be taken with respect to all
transactions involving land. After having
ascertaining the bonafides of the land, it would be
advisable to appoint a good lawyer to ensure
clear title of the land.

1. Architecture/Engineer:
Please
make
sure
that
choose
a
reputed
Architect/Engineer from near by area where school is
being constructed
2. Contractor:
The contractor is responsible for arranging and
supervising the workmen for different activities of
construction. Contractors are generally paid either on per
square foot basis or in terms of labour employed. It goes
without saying that the reliability of your contractor
defines the quality and durability of the construction.
3. Carpenter:
The carpenter handles any woodwork – the making of
doors and windows, frames for grills and related fittings
and furniture for the house.
4. Painter:
After completing the construction process, the painter
can correct any minor detects and paint the house to
achieve the desired look. Information on painters is
available at paint stores or you could get a
recommendation from an acquaintance who has
recently painted their building.
5. Electrician:
All of the electrical layout and wiring is designed and
completed by the electrician. Please ensure that only
licensed electricians are employed for this activity.
Electricians can normally be contacted at electrical
equipment shops in the area.
6. Mason:
Laying concrete and bricks, maintaining proper
even levels and surface layouts – implementation
issues like these are the responsibility of the
mason.
7. Plumber:
Water supply, sanitation and waste disposal are
important elements for any house. The plumber
will help you design the best location and layouts
for these. He will also help you install sanitary
ware and pipes. For references, ask at sanitary
ware and hardware stores.
8. Building Material Suppliers:
Purchasing all building materials from authorized dealers
of reputed companies is one way of ensuring a durable,
long-lasting home. It is advisable to check specifications
prior to purchase. Looking for low-cost options may lead
to substandard results in construction.
9. Neighbours:
Some useful tips can be picked up from people who
have recently completed constructing their own homes.
These tips could help in avoiding pitfalls, and lead to
major savings in time and cost.
There are two types of rate contracts for
construction:
1. A turnkey rate contract, which includes cost of
construction, labour and cost of building
materials.
2. Labour contract rate, which excludes cost of
materials.
•
In practice, people who are able to devote time
to the construction process opt for option 2. If,
however, option 1 is chosen, please ensure that
both the quality and quantity of materials to be
used is discussed beforehand.
Some Tips for saving Time and Money
• Understand the present and future needs of your
school.
• Ensure that the construction plan, working drawing and
the estimated costs are in place before starting
construction.
• Ensure maximum natural light in all the rooms by
providing adequate number of windows and ventilators.
• Avoid non-standard size doors and windows or
eliminate them altogether, if not necessary.
• Use materials available locally.
Contd.
 Plan for regular supply of materials beforehand. This
avoids delays in construction.
 Maintain minimal stocks of construction materials at the
site.
 Stock all the raw materials properly so that they are
safe.
 Fixtures and fittings should be chosen for durability
rather than just appearance.
 Electrical points need to be minimized.
 If air-conditioning is to be used, plan the location in
advance.

 Sand
Procedures for Identifying Good Quality Sand:
 Good quality sand can be identified easily by taking a
handful and closing your fist around it. Any form of
contamination like mud will stick to your palm. The
presence of clay, grit, pebbles or dirt could be harmful in
construction. They need to be screened or sieved from the
sand before use.
 A slightly more scientific method could be to fill half a glass
tumbler with sand, add water into the tumbler and stir. Any
form of contamination could result in the water turning
muddy. As a rule, if the content of mud or dust exceeds
4% of the total quantity of sand, the sand would be
washed clean before use. In short, sand should not
contain clay, dirt, mica or sea shells.
 Wet Sand and Associated Problems
Sand should not contain water. Generally, if the sand
contains about 5% of water, then use 25% additional
quantity of sand for construction. Sometimes
construction labourers add too much water which is
detrimental to durable construction.
 Bricks and their Selection
Bricks can be tested just by observation. Visually they
should be in the correct shape with sharp corners. A
uniform colour also ensures good quality. One test is
to break a brick, it should not scatter into small pieces.
Another process of testing is to strike two bricks
against each other. Good quality bricks produce a
ringing sound when struck with each other. Also, a
good brick when dropped from a height of about a
meter should not break. Another practical test is to
soak a brick in water for about 24 hours. The weight of
the brick before and after soaking should be checked.
If the brick shows an additional weight of more than
15% after soaking, it should be rejected. For example,
a dry brick weighing 2 kg should not weigh more than
2.3 kg after being soaked in water for 24 hours.
 Steel Rods (Reinforcement Bars)
Concrete has good compressive strength. However, it does
not withstand tensile or bending stresses. To overcome
this, reinforcement bars (steel rods) are placed inside the
concrete to provide the necessary strength. Hence, the
term Reinforced Concrete Cement.
We suggest that only BIS certified steel bars should be
used for RCC construction. It is essential to ensure when
purchasing them that no rust is visible on the bars. The
steel bars are normally fixed in pre-designed formats. So,
be careful that all design requirements are strictly adhered
to.
 Cover Block
Use of cover blocks are highly recommended to ensure that
adequate concrete covers the steel bars. Cover blocks are
normally made using mortar and should be of a thickness
of 2 inch for footing, 1.5 inch for columns and ½ to ¾ inch
for slab and beam structures.
 Stone Gravel/Coarse Aggregates
Coarse aggregates are normally small pieces of stone
which give concrete its strength. The two most commonly
used sizes are ¾ inch or 20 mm and ½ inch or 12 mm. At
times both are used together in the ratio of 60:40 or even
up to 70:30.
While selecting the coarse aggregate, the following points
should be kept in mind:
• Coarse aggregate should be solid, in the shape of a cube
and free from dirt.
• Any form of contamination should be immediately removed.
• The right proportion of large and small size pieces should
be selected. This is to ensure that the space between the
large stonechips is filled in by the smaller pieces.
 Water
Water should be free of all contamination when used in
construction. Salty water or sea water should never be
used for making RCC. It is advisable to use
potable/drinkable water, as far as possible.
Addition of excess water is detrimental to concrete. A low
water to cement ratio makes the construction strong and
durable.
It is always useful to have containers of five or ten liters of
water handy while carrying out construction. One bag of
cement normally requires 25 liters of water.
 Test of Quantity of Water
As a general rule, after mixing the water with cement
and other ingredients, a ball of concrete mix should be
made. If this ball is thrown up in the air to a height of a
meter, it should not break or crumble as this is an
indication of excess water content. It would then be
advisable to reduce water content in the mix
immediately.
 What to Look for when you buy Cement
It is advisable to purchase only well known brands of
cement from reliable sources. A few rupees extra is money
well spent as an inferior quality cement could lead to
significantly higher cost later. Remember that cement once
used cannot be replaced or improved in the same way as
you can do with tiles and other such work. Besides, the
cost of cement is only a small percentage compared to the
total cost of construction. As a rule, cement should
constitute only 10%-14% of the total construction cost. For
example, if the total expenditure is about Rs.5 lakh, the
cost of cement is likely to be 10 to 14 percent, which is
around 500 bags. At a premium of five rupees per bag for
good quality cement, the cost of cement will increase by
about Rs.2500/-, which is quite insignificant when
compared to the total budget of Rs.5 lakh.

concrete better longterm strength and
durability.
 Proper usage of Cement
• An optimum quantity of cement must be used for any
construction. It is a myth that high grade cements can be
used in lower quantities. If lower quantities of cements are
used, then an additional quantity of water is required. This
would mean a distorted water to cement ratio, and the
result would reduce the strength and durability of the
concrete.
• A common misunderstanding is that high grade cements
result in better results. The grade of cement only indicates
its compressive strength after a period of 28 days.
However, blended cement continues to increase in strength
beyond that period. Therefore, with the long term objective
of a lasting home, blended or composite cements are
usually preferred. Yet another misconception is that quick
seeking cement should be used. It is advisable to allow all
concrete structures the requisite time for setting.
 Ask the mason or contractor to be patient if they
complain about the time it takes to set. Slower setting
cement does not necessarily mean that it will not
provide long-term strength.
 Some people believe that the colour of cement
determines its quality. This is totally untrue. The colour
of the cement is determined by the quantity of the raw
materials used in its manufacture.
Some Additional Tips
• If you have doubts about the quality of cement, the first
step would be to consult the manufacturer. However, this
simple test will also suffice. Make a paste of a cement with
one-fourth the quantity of water and make cubes or blocks
of 50x50x20 mm size. Leave aside the cubes/blocks for a
day. Test them to see how easily they break. If the cement
is of good quality, the blocks will not crumble if you try to
crush it with your fingers.
• Cement is known to react with water and, therefore,
protection from moisture is of paramount importance. It
would be best to store the cement bags in an enclosed
godown. Ideally, the bags should also be placed on a
platform at least 6 inches above floor level, leaving a gap
away from the walls. Normally, each stack should not have
more than 15 bags. A ‘first in first out’ process should be
followed. Cement should always be used within 2–3
months of its manufacture.
Formwork (Shuttering)
This is the temporary formwork meant to support your
construction while the concrete work is in progress. It
comprises of wood props, plywood and steel plates. A
good formwork should be strong, solid and without any
gaps so that water leakage through through the joint or
any gap is almost minimum. 24 gauge micron
polythene sheet should be used to prevent any water
leakage. Apply a layer of releasing agent (like diesel or
grease mix) to the formwork where the concrete is to
be poured. This enables it to be removed with ease and
ensures a smooth finish.
Concrete Work
For RCC work, the ingredients of concrete should be in
the ratio of 1:1.5:3 (cement one part, sand 1.5 parts
and coarse aggregates 3 parts). All of these items are
measured by volume and are best measured using a
container of wood or steel. Traditionally, the size of this
container would be 350x250x400 mm, which holds 35
litres. While preparing the mixture, 25 litres of water
must be added per bag of cement. If the mix is
prepared in a machine, it should be mixed for at least 2
minutes so that the mixture blends well with the water.
If you are mixing by hand, then it is advisable to
prepare a dry mix of cement and sand in a tray. After
blending, when the colour appears uniform, the coarse
aggregate may be added and then finally add the
water.
The concrete mix should be cast before it begins to set.
Normally, concreting should be completed within 30
minutes to an hour. In case of any delay, do not add any
more water just to improve its flowing consistency. The
casting of concrete should be done continuously, i.e.,
layer over layer. The mixture should be poured from a
maximum height of 1.5 metres. This avoids the
ingredients separating. The mixture must then be
properly compacted. It is best to complete this task with
a needle vibrator. If this is unavailable, an iron rod could
be substituted. This is done to ensure that there are no
air bubbles in the concrete, as this would weaken it.
Brickwork
 The following mortars are suggested: for a 4 inch wall (divider walls in the middle of the
house)
cement:sand = 1:4
for a 9 inch wall (outer walls)
cement:sand =1:6
• Before beginning work, ensure that the bricks have been
soaked in water for 8 hours. Do not use completely wet
bricks as the cement mixture will not stick properly.
• After joining the bricks, the correct cutting or raking of the
mortar is essential. This helps the adhesion of the plaster.
The thickness of the brick joints should not be more than 1
cm. The vertical joints should never be continuous.
It is best not to lay bricks higher than 5 feet at a time, as the
mortar should given adequate time to set. The task of
joining should begin from 2 corners (3-4 layers). The parts
in between should be filled within the leftover frames. The
line level and plumb need to be continuously checked.
Curing must be done for at least 10 days.
In this context, please read the section on the quality of
bricks carefully.
• Plastering
Plaster is the skin of your house. Just as our skin gives
shape and texture to our body, and protects your house
from damage caused by salts, acid and rain. It also
makes your house look beautiful. Therefore, it is
important to pay close attention to it.
 Ensure that the wall is slightly wet before starting the
plastering. Dry walls adsorb water from the plaster and
this will cause the plaster, in time, to fall off.
 Check that the mason has not prepared the mix for the
whole day. The mix must be prepared only in small
quantities; as much as will be used in an hour. Your
mason can, however, keep a large quantity of dry mix
ready.
 The usual mix proportion is:
1:5 to 1:6 for internal plaster
1:4 to 1:5 for external plaster
1:3 to 1:4 for the ceiling
However, if the sand particles are very fine, 1:4 ratio
mix is suitable for all three areas.
 Use wooden float for finishing as steel floats can
sometimes cause small cracks.
 Curing should be done for 10–14 days.
Curing
The process of maintaining moisture in the concrete is
called curing. Concrete begins to dry after casting. So,
the parts exposed to the environment should be cured
to ensure that the concrete surface is never dry. This
needs to be done continuously, till the mandated period
of curing. Usually, 10-14 days of curing is considered
optimal. It is best to make small curing ponds or bunds
on flat or horizontal surfaces. For vertical surfaces, you
may wrap jute or hessian cloth on the surface and then
pour water onto it. This helps keep the surface wet for
longer periods.
Electrical Works
Select electrical goods for your house carefully (these
must be ISI marked).
 Make provisions for switch boards at the beginning of
construction, or it will clash with the décor of your
house later on.
 Make proper arrangements for earthing in your house
and have it checked regularly.
 Do not make several temporary connections from one
point.
Avoid using too many joints in the electrical wiring. Use
good quality wires and insulation material.
· To protect your electric equipment, use a fuse on every
power board.
· Do not use
connections.
extension
boards

permanent
· Keep the power supply cord safe from water, heat and
oil.
· Keep electrical materials away from children.
Note: Use electricity with restraint. Have your
connections, wiring etc. checked regularly. Get your
electric work done only from a registered or licenseholding electrical contractor.
Plumbing
 Use good quality ISI marked GI pipes and fittings
for the water supply.
 PVC pipes for sewage discharge are both durable
and convenient.
The joints of pipes and fittings must be leak-proof.
They should be double checked before laying the
tiles.
Painting
Painting provides protection to the walls of your house as
well as so much more. It is said that the colours of your
house reflect your personality. The painting work is
broken up into three parts:
1.
Pre-painting Work
2.
Surface Preparation
3.
Painting
Painting your Interiors step by step:
 Clean the surface thoroughly with sand-paper.
 Then apply a coat of good quality primer. If required, apply
a second coat.
 Once the primer has dried, apply one or two coats of
acrylic-based putty.
 Apply a further coat, or two or three coats. Thinner should
be used as per requirement.

Here are some Suggestions to make the Painting
Work Easy:
If there is any dampness or cracks or other damages on
your walls, have these repaired first.
Select in advance the shades and colour schemes you
wish to have on your walls. You can get help choosing the
colours from catalogues, displays and show-rooms of
well-known companies.
Find out the entire product range of the company so you
can select the colour that suits your needs.
Choose light colours for outer walls. This will keep interior
temperatures low.
Also use light colours on internal walls where a lot of
natural light is reflected.
