Practical

PRACTICAL:

  1. Chain Survey:

    1. Practice in unfolding and folding chain alignment of lines-measurement of distance between given points and their booking.
    2. Practice in chaining and taking offset, use of optical Square and Cross staff setting out right angles looking of measurements testing of chain, tape, optical square and Cross Staff.
    3. Procedure in conducting Chain Survey reconnaissance preparation of rough sketch. Selection of base lines and Station points fixing of stations etc.
    4. Chain Survey of small plots by triangulation, looking and plotting the same.
    5. Chain Survey of built-up plots, locating details, booking and plotting the same.
    6. Taking horizontal measurements on sloping ground overcoming obstacles between two points one of which is invisible or inaccessible from the other.
    7. Chain Survey of an extensive area, locating detail plotting and finishing the same in ink or colour.

    288 hrs.

  2. Compass Survey:

    1. Practice in setting up a compass and checking its accuracy-taking bearings and calculating angles (conversion from W.C.B. to R.B.).
    2. Determining the bearings of a given lines and establishing lines of given bearings - laying out a rectilinear and polygonal plots of ground using a compass and a tape.
    3. Conducting closed traverse of built up field, and plotting the same finishing in ink or colour.

    (3 weeks)

  3. Plane Table Survey:

    1. Setting up of plane table levelling centering, and orientation. Surveying an area with plane table of built up areas.
    2. Traversing with Plane table of built up areas.
    3. Running and open traverse with plane table and fixing details. Inking, finishing, colouring etc.

  4. Levelling:

    (4 Weeks)

    1. Practice in setting out a level and performing temporary adjustments practice in reading staff.
    2. Demonstration of permanent adjustment of level.
    3. Practice in differential levelling including reciprocal levelling and establishing bench marks, reading of inverted staff practice in booking readings.
    4. Carry out route Survey longitudinal & cross section of a road project its plotting and calculation of earthwork.
    5. Road project reconnaissance, preliminary and final location Survey including preparation of route map to scale, taking profile and section with level plotting; marking formation levels. Calculation of earthwork and other material for laying road includes estimation of earthwork.

  5. Theodolite Survey:

    (5 Weeks)

    1. Practice in setting up a theodolite and taking readings. Measurement of horizontal angles by repetition, reiteration methods. Entry of Field book.
    2. Practice in measuring vertical angles, setting out given vertical angles and entering in the field book.
    3. Running a closed traverse over a given area, booking calculating the co-ordinates and plotting the traverse.
    4. Setting out compound Curves, transition Curves with theodolite.

  6. Lay-out of Building from the Plan mentioning size of the rooms, etc.

  7. Engineering Drawing:

    1. Drawing different types of lines, lettering etc.
    2. Construction of Plain, Comparative diagonal and vernier Scale Drawing of Conventional signs used in engineering Survey, Cadastral Survey, Building drawing practice.

Note: As this subject is Practical oriented, it is therefore, important to run through the theory and practice simultaneously. Some chapters of Practical are also to be carried out simultaneously for completing the syllabus. Emphasis to be given on work topic rather than simple terms of explanation which can be done during practical work.
