Testing and Consultancy Cell Guru Nanak Dev Engg. College Ludhiana(Under Dean Of TCC GNDEC Ludhiana Dr. H.S RAI)
Dean : Dr. Hardeep Singh Rai
Established in 1979
Provides Consultancy Services in Punjab, Haryana, Himachal, J&K and Rajasthan
Consultancy Services are being rendered by various Departments of the College to the industry, Sate Government Departments and Entrepreneurs and are extended in the form of expert advice in design, testing of materials & equipment, technical surveys, technical audit, calibration of instruments, preparation of technical feasibility reports etc
This consultancy cell of the college has given a new dimension to the development programmes of the College. Consultancy projects of over Rs. 1.35 crore are completed by the Consultancy cell during financial year.

STANDRAD PENETRATION TEST IS: 2131-1981 (Reaffirmed 2002)
Investigation Of Soil
Objective
This test is common used in situ test especially for cohesion less soil. Which can not be easily sampled . The test extremely used for determine the relative density and angle of Shearing resistance of cohesion less soils. It can also determine unconfined Compressive strength of cohesive soils.

Procedure
We are performed this test at delta city Ludhiana near alamgir for high rise building.
After digging the bore hole . The sample is taken from 5ft,10ft,15ft & 20ft depth so on with the help of sampler equipment.

TESTS ON HARDENED CONCRETE
NON-DESTRUCTIVE TESTS
REBOUND HAMMER
NON-DESTRUCTIVE TESTS REBOUND HAMMER
To assess the likely compresive strength of concrete by using rebound hammer.
As per IS: 13311 (Part 2) - 1992.
PRINCIPLE
The rebound of an elastic mass depends on the hardness of the surface against which its mass strikes. When the plunger of the rebound hammer is pressed against the surface of the concrete, the spring-controlled mass rebounds and the extent of such a rebound depends upon the surface hardness of the concrete. The surface hardness and therefore the rebound is taken to be related to the compressive strength of the concrete. The rebound value is read from a graduated scale and is designated as the rebound number or rebound index. The compressive strength can be read directly from the graph provided on the body of the hammer.
APPARATUS
1.The Rebound Hammer has two types
Graphical Rebound Hammer
Digital Rebound Hammer
2. Scanner
RF Scanner

Rebound Hammer
PROCRDURE
Before commencement of a test, the rebound hammer should be tested against the test anvil, to get reliable results, for which the manufacturer of the rebound hammer indicates the range of readings on the anvil suitable for different types of rebound hammer.
Apply light pressure on the plunger - it will release it from the locked position and allow it to extend to the ready position for the test.
Press the plunger against the surface of the concrete, keeping the instrument perpendicular to the test surface. Apply a gradual increase in pressure until the hammer impacts. (Do not touch the button while depressing the plunger. Press the button after impact, in case it is not convenient to note the rebound reading in that position.)
Take the average of about 15 readings.
