3

• 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 _at_
  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 12.

4

•  
• 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.

5

• b. Assistance that to be taken A Check List 
• Check List
• 1. Architect/Engineer
• 2. Contractor
• 3. Painter
• 4. Electrician
• 5. Carpenter
• 6. Mason
• 7. Plumber
• 8. Supplier of Building Materials
  
• 9. Neighbours
• 10. Guardian and VEC Member

6

• 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.

7

• 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.

8

• 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.

9

• 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.

10

• There are two types of rate contracts for
  construction
• A turnkey rate contract, which includes cost of
  construction, labour and cost of building
  materials.
• 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.

11

• 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.
12

• 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.

17

• 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.

18

• 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.

19

• 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.

20

• 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 6040 or even up to 7030.
• 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.

21

• 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.

22

• 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.

23

• 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.

24
Type Features Use
Ordinary Portland Cement (OPC) It is prepared by grinding clinker along with gypsum. This is available in several grades like 33, 43 and 53. Can be used for all normal works.
Blended/Composite Cement High quality clinker is inter-ground with gypsum and a performance enhancing bonding material like slag or poggolana. Comprises Portland Slag Cement (PSC) or fly ash based Portland Poggolana Cement (PPC) Can be used in all general constructions such as concreting, brick joining, plaster and special constructions. It gives concrete better long-term strength and durability.
25

• 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.

26

• 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.

27

• 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 23 months of its
  manufacture.

28

• 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.

29

• Concrete Work
• For RCC work, the ingredients of concrete
  should be in the ratio of 11.53 (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.

30

• 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.

31

• Brickwork
• The following mortars are suggested -
• for a 4 inch wall (divider walls in the middle
  of the house)
• cementsand 14
• for a 9 inch wall (outer walls)
• cementsand 16

32

• 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.

33

• 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.

34

• The usual mix proportion is
• 15 to 16 for internal plaster
• 14 to 15 for external plaster
• 13 to 14 for the ceiling
• However, if the sand particles are very fine,
  14 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 1014 days.

35

• 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.

36

• 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.

37
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
extension boards for permanent connections.
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 license-holding electrical
contractor.
38

• 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.

39

• 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.

40

• 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.
