8.  SITE LOCATION
Advantages Of this Site
 Land

9.  FORMWORK
SIGNIFICANCE OF FORMWORK:-
1) Formwork constitutes 30% of the cost and 60% of the time in concrete construction.
2) Quality of concrete finish and soundness of concrete depends very much on the
formwork system
3) Desired shape of concrete is not possible if formwork not done properly.
4) Formwork should be properly designed, fabricated and erected to receive concrete.
5) Accidents happen because of the faulty formwork and scaffolding or staging
SAFETY IN USING FORMWORK:-
1) Components are light in weight for manual handling.
2) Loose or hanging components are minimal.
3) Appropriate use of tools.
4) Minimum operations are involved in each reuse.

11.  PLANNING

12. Planning of a CPWD Project mainly includes:-
 Pre-requisites for execution of work.
 Deposit works
 Preparation of estimates.
 Execution of original work.
 Expenditure on survey, exhibition.
 Register of buildings.
 Green building norms.
 Preparation and accounting of Standard Measurement book.
 Preparation and passing bills for payment.
 Documentation of accounts.
 General departmental charges.
 Contracts and forms.
 Preparation of tender documents.
 Publicity of tenders
 Sale of documents
 Earnest money.
 Issue of material to contractors.
 Issue of tool and plant.
 Payment to contractors
 Insurance
 Losses or damages.
 Budgeting
 Quality assurance and technical audit wing.
 Inspection and Audit by Chief Controller.
 Public accounts committee.

13.  SEQUENCE OF STRUCTURE
WORK
 Site clearance
 Demarcation of site
 Positioning of central coordinate i.e. (0,0,0) as per grid
plan
 Surveying and layout
 Excavation
 Bar binding and placement of foundation steel
 Shuttering and scaffolding
 Concreting
 Electrical and plumbing

14. Construction Process And Material Used
CONCRETE
1) Normal Concrete made of Fine Aggregate +
Regular Aggregate + Water
2) Concrete will set up hard enough in normal
weather in about 3 hours
3) It takes 28 days for it to reach its fullest strength

15. Plastering
 Make sure to wet the surface at which you are applying plaster.
This will ensure better sticking of the plaster.
 Don’t use dry cement over the plastic surface, as there chances of
it getting distorted.
 Use the appropriate amount of water while mixing chemicals or
else, there are chances that it won’t set up to the brick wall.
 Wait for 24 hours after plastering the wall and splatter water
over it for the next 3-4 days. The splattered water will ensure
better set up of the plaster.
 If you are doing the patch up work in a smaller area, like in a
room, make sure to keep newspaper pieces on the ground, so
that if the plaster falls over it, it can be removed. Once dried, it is
difficult to remove the plaster.

19. Surface Preparation

20.  Allow newly plastered surface to mature for a period of at least 6 months
before painting.
 Rectify existing surface problems such as dampness, cracks etc. before
actual painting process.
 Check for hand prints, greasy fingerprints, algae as well as dirt and stained
marks.
 Use a scraper, putty knife or scrub brush to remove any dirt, grease, rust, or
flaking.
 Fill in the holes, cracks and joints with plaster.
 Clean and dry the surface.
 Make sure the area to be painted is well ventilated as well as free of dust.
 As far as possible, don’t paint under much humid conditions.

21. Painting

22. Objects to be Painted
Interior walls
Exterior Walls
Metal Surfaces
Wooden Surfaces

23. INTERIOR WALLS
 Apply a coat of Wall Primer (water thinnable) on new surfaces.
 Fill and level the minor undulations of wall by applying putty. In case of major
undulations on the wall surface, POP (Plaster of Paris) work needs to be
carried out. Ensure that the surface is uniformly smooth by sanding after POP
or putty work.
 One liberal coat of Wall Primer (solvent thinned or water thinned) is
recommended on puttied areas before the application of top coat. The primer
should be allowed to dry for 10 - 12 hours. If the primer coat is not applied over
the puttied areas, there can be a patchy appearance of the top coat.
 Avoid application of putty or filling compound while painting exterior surfaces.
Fill up cracks with a 1:3 (by volume) cement and sand mixture.
 All external drainage pipes must be checked for rusting or leakage. Any faulty
plumbing must be rectified
 Special attention must be given to the roof. Check for cracks near the edges and
close to the water reservoirs. Proper masonry or waterproofing work on the
ceiling will enhance the performance of the paint.

24.  Exterior Walls
Pre-painting
 For exterior surfaces it is very important to undertake
repairs of any wall imperfections before commencing
painting.. Avoid applying putty or filling compound
while painting exterior surfaces. Fill up cracks with a
1:3 cement and sand mixture.
 All external drainage pipes must be checked for
rusting or leakage. Any faulty plumbing must be
rectified.
 Special attention must be given to the roof. Check for
cracks near the edges and close to the water reservoirs.
Proper masonry or waterproofing work on the ceiling
will enhance the performance of the painted surfaces.

25. Exterior Wall Painting
 Apply a liberal coat of Asian Paints Exterior Wall Primer using
recommended method.
 Apply two coats of top coat paint at recommended dilution. You can
use Apex Weather Proof Exterior Emulsion or Apex Textured Exterior
Emulsion or Ace Exterior Emulsion as top coat.
 A gap of 4 to 6 hours must be given between two coats.
 It is recommended that horizontal surfaces like the tops of awnings
and Parapets must be given an additional coat for greater protection.

26. Metal Surfaces
 Surface should be free from dirt, dust, grease, rust, moisture etc. The
area which is not to be painted must be covered by a masking tape,
paper and/or cloth.
 For best results, allow the primer coat to dry for 6 hours and dry
sand with emery paper no. 320 before application of subsequent coat.
 Allow the surface to dry overnight after application of primer as above.
 Apply top coat using the recommended thinner. For best results, apply
two coats allowing 8 hours of drying time between two coats.
 The first coat should be wet sanded with waterproof emery paper
grade 400 before applying the second coat.

27. Wooden Surfaces
Surface Preparation:
 Previously painted wooden surfaces must be properly sanded to
remove any dust or grease.
 Apply wood primer by brush, after thinning to given ratio by
recommended thinner.
 Allow it to dry for 6-8 hrs then apply putty.
 Sand the applied putty with number 180 sand paper and then apply
second coat of wood primer.
 Now the wooden surface is ready for painting with the top coat

29. Painting
 For opaque finish you can choose conventional enamels Apply wood
primer by brush, after thinning to given ratio by recommended thinner.
 Sand the applied putty with 180 no. sand paper & apply 2nd coat of
wood primer.
 Now the wooden surface is ready for painting with the top coat
 Enamels are normally applied by brushing although they can also be
sprayed.
 The drying time of enamels is longer; hence care must be taken to
ensure a dust free environment while the paint film is drying.
 Two coats of paint is sufficient in most cases, however if the earlier
paint shade was significantly darker than the new shade an additional
coat of paint is recommended

32.  CONCLUSION
 It was a wonderful learning experience at CPWD office, IP
Bhawan, New Delhi 110002 for Six Weeks.
 I gained a lot of insight regarding FINISHING aspects of
Construction site.
 I was given exposure in almost all the departments at the
site, but I had liked to highlight the areas of safety, quality
management, material management and execution.
 I hope this experience will surely help me in my future and
also in shaping my career.
