Job Order of soil investigation against Provn of stabilized commercial power supply at Radar site at AF Stn Utarlai

Job work for complete soil investigation as described below at site of "Provn of Stabilized Commercial Power Supply at Radar Site at AF Stn Utarlai" (A) To evaluate sub grade strength and soil properties through bore holes shall be done on site. Graphical boring log shall be developed for each bore hole summarizes the result of soil explorates. The Graphical log shall include location date of performed type of exploration, surface elevation, depth of material, samples identification numbers as shown in figure 1 (i.e. typical boring log enclosed). Sample shall be collected of the depth of every 1.00 Mtr or soil strata change upto 6.00 Mtr to establish soil profile complete all as specified and directed.
