How can I become a QA QC Civil Engineer?

  I am sharing my experience that how I became a QAQC Engineer… After completing my diploma in civil engineering from North Calcutta Polytechnic, I have joined L&T construction as a QAQC Lab Technician and there learned every test by doing self-hand in under guidance of my Quality Head with parallel study of relative Code and specification.   After 1 year when I get confidence on monitoring all lab test activity and minimised the test error in front of client, then I take responsibility to preparing test reports for final submission and day by day I became expert and my senior had taught me and given more responsibility.   Finally, after 3 year I become a QA QC Civil Engineer.   BASIC KNOWLEDGE & SKILLS ·         Soil Testing (GSA, LL-PI, FSI, MDD, CBR, FDD by Sand replacement method & NDG). ·         Aggregate Testing (Gradation, AIV, FI-EI, LAAV, Bulk Density, Spe...

Material Specification for Gabions Wall & Stone Pitching

A Gabion structure is prepared from pre-assembled rectangular cages made of double twisted steel woven wire mesh filled with rocks/ boulders. It is a simple gravity retaining  structure, which retains soil with its weight. These types of structures are in use in highways, bridges, canal linings, buildings, shore protection works, etc The porosity of gabions prevents the pore-water pressure development behind the walls which, is one of the major advantages of these kinds of systems. These structures blend with the  surroundings and allow vegetation to take roots through the structure which enhances the life  of the structure. Reduced carbon foot prints are also a noticeable feature when compared to  conventional solutions. Reference Code: (1) MORTH 5th Rev.
