Surveying Lab
Surveying is the skill of determining the relative positioning point or object by measured angle or distance. Transversing is done to plot the detail of any building or other structure. Whenever there is a need for precise measurement the triangulation survey is performed. Plane tabling is the method used in surveying the field observation and plotting to determine the relative position of point horizontally as well vertically. Contour is an imaginary line on the ground joining the points of equal elevation.

List of experiments.

  • Determine the difference in elevation of two given point.
  • To determine the height of an object, the base which is inaccessible using a theodolite.
  • A) To determine the multiplying constant K and additive constant C of a tachometer.

    B) To find distance & elevation of five points around the instrument station.
  • Plotting the details of a given area by the plane table.
  • Determine the position of the instrument station.
  • Contour survey of a given area using the square method.
  • To trace out the simple circular curve with the help of chain & tape only.
  • To trace out the simple circular curve by theodolite.
  • To determine the height of a tall object by two plane method.

Structure analysis lab
The behaviour of various structures under the action of the load is studied in S.A. lab. Three hinged & two hinged arches experiment are premed to determine the maximum load that a particular arch can sustain. Apart from maximum load position, horizontal thrust deformation and type of failure are also found out from these experiments. Deformation of the beam is determined by Maxwell Betti's law verification. This experiment gives the maximum permissible load for a beam for certain deformation.
Without knowing the max permissible load a beam cannot be designed. Euler’s law verification reveals the behaviour of strut under the application of load for different end condition. This law is used to determine the max load & effective length of the column and hence its is used in designing columns.

List of Experiments

  • To determine the flexural rigidity of a given beam.
  • To verify moment- area theorem for slope and deflection of a beam.
  • To study the behaviour of different types of struts.
  • To determine experimentally and analytically the load in the three suspension rods supporting the elastic beam with concentrated loads hung midway b/w two of the suspension rods when

a ) Suspension rods are attached at their upper and rigid support.
b) the upper end of the central rod is attached to the centre of a similar elastic beam.

  • To present the experimental study of a three-hinged arch for a given system of loading and to compare the result with those obtained analytically.
  • To determine the elastic displacements of curved member experimentally and verification of the values by analytical method.
  • To determine experimentally & horizontally

Transportation Engineering
Transportation engineering is the application of technology and scientific principles to the planning, functional design, operation and management of facilities for any mode of transportation in order to provide for the safe, rapid, comfortable, convenient, economical and environmentally compatible movement of people and goods. Highway engineering is a very important part of Transportation Engineering. It includes handling the planning, design, construction and operation of highway, road and vehicular facility.

List of Experiments

  • To determine the impact value of aggregates.
  • To determine the crushing value of stone aggregates.
  • To determine the coefficient of hardness or resistance to wear of stone aggregates by:
  • Los-Angeles Abrasion Test on aggregates.
  • Deval Attrition Test on aggregates.
  • Dorry’s Abrasion Test on aggregates.
  • To determine the flakiness index and elongation index.
  • To examine the penetration of Bituminous Material.
  • To determine the ductility of Bituminous Material.

Fluid mechanics
Flow and fluid properties are studied in a hydraulic laboratory. Determining of energy and momentum coefficient help in determining the energy and momentum of flowing fluid without applying these coefficients a designer may reach a wrong decision.
Actual discharge is determined by multiplying the theoretical discharge to a coefficient called discharge coefficient. This coefficient is determined in the lab and it is different for different orifices, notches and weirs. Study of weirs, notches and orifice helps in designing of them in real life. Weirs are generally constructed on river beds to raise the water level. Notches are attached to canals to control the flow of water.

Concrete Laboratory
Properties of cement and concrete are determined in the concrete lab. Normal consistency gives the idea about the quality of a selection of cement for a particular project. Fineness modulus of cement is related to the initial and final setting time to decide the work rate of concreting and the curing. Generally, the cement having less initial setting time is not desirable since the primary bond which has been formed are broken away while concreting.
Compressive & tensile strength determination of concrete is very important in design filed, without knowing the compressive & tensile strength of concrete a concrete structure or any component cannot be designed workability of concrete is also a factor which should keep in mind while designing.

List Of Experiments

  • Determine the quantity of water required for the normal consistency of cement.
  • Determine the initial and final setting time of concrete.
  • Determine the compressive strength of normal mix concrete of a given grade.
  • Determine the modulus of rupture of concrete.

Soil Mechanics
Soil mechanics is a branch of civil that describes the behaviour of soil. It differs from fluid mechanics and solid in the sense that soil consists of a heterogeneous mixture of fluids usually air and water and particles clay, silt, sand and gravel. There are structures that are supported on or made of soil or structure that are buried in soils like bridge foundation, retaining walls, dam system etc. so we need to know the engineering properties of soil. So we conduct laboratory tests to find out various engineering properties of soil.

List of Experiments

i) Sand replacement method
ii) Core cutter method
Determination of Liquid limit using Casagrande's apparatus.
