Amount

Transportation & mobilization of equipments.

M&L for soil investigation to carry out bore hole of 150mm dia with depth of 06m. Soil investigation shall be as per IS 1892-1975. Undisturbed soil samples shall be collected at 1.5m interval and at every change of strata. STP shall be done till ‘N’ value of 50 or refusal whichever is earlier. As per IS-1892 (Clause 3.6.5.3), drilling for 3.0m depth inside the rock is essential to ensure boulders or layers at cemented soil are not mistaken for rock. Soil investigation report shall be submitted in 06 No Copies duly signed by qualified engineer with degree M. Tech having experience of minimum 02 Years. The Name, designation and qualification at the signatory shall be clearly specify. Soil investigation report shall include following details:- (a) Grain size analysis, identification & classification of soil. (b) Unit weight (bulk density), natural moisture content liquid limit, shrinkage limit, plasticity index, specific gravity, dry density and degree of saturation of soil. (c) Differential free swell index (%) & swelling pressure if expansive soil is encountered. (d) Shear Parameters (C-Phi Analysis). (e) Consolidation test (for cohesive soil only). (f) Chemical Analysis of soil and ground water (Water to be obtained from bottom of the bore hole). (g) Presence of loose soil if any, and its depth. (h) If weak soil with lesser N Value as specified in table-1 of IS 1893 (Part-I) 2016 is encountered then evaluation of liquefaction potential shall be assessed and remedial actions to be adopted shall be specified. (j) Crushing strength, degree of weathering (CR Value) and RQD of rock samples.

(k) If open foundations recommended – Calculation of Net SBC at 1.5m, 2.0m, 2.5m 3.0m from shear as well as settlement criteria SBC value shall be calculated based on C-Phi analysis as well as SPT Value for calculation formulae given in IS : 6403 Shall be used. (l) If pile foundation recommended – Type of pile, recommended depth of pile, lenth of socketing, minimum spacing of working piles, and safe load capacity of piles of different diameter etc shall be specified along with supporting calculations piles capacity in compression uplift & lateral loads shall be given. (m) Recommendations regarding type of foundation to be adopted & Net SBC/Pile capacities to be adopted also recommdations shall be given regarding stability of soil and soil stabilization required if any (n) Bore hole positions duly marked on plan and their distance from adjacent prominent reference points. This plan shall be signed by GE & Soil Consultant. (o) Bore log details shall be as per Appx ‘D’ of IS 1892, N values depth wise shall also be shown in bore log details Bore log details shall be signed by GE & soil consultant. (p) SBC should be worked out for diff sizes of footing. (q) Depth of Ground waer table in peak monsoon and peak summer after co. relation of result with seasonal variation of water table in station.

Making of trial pit of size 1.2m x 1.2m x 3.0m for collection of sample for conducting California Bearing Ratio (CBR) test in Soaked and unsoaked condition of DS Sample at 1/1.5 M depth & submission of report with analysis which includes the determination of proctor density test, Soil Gradation, Atterberg Limit (L.L. &P.L.) and Determination of free swelling Index etc.

Carrying to Topographical survey using total station for specified area (Approx Area = 3500 Sqm) including chart for contour level at a grid of 3m x 3m with hard copy of Autocad and in excel shed att as directed. RL of GL of coruers of buildings with respect to BM should invariably be mentioned. Note :- (i) The rate quoted for above items shall be include necessary arrangement for mobilization and demobilization of equipment, tools & plants required for soil investigation, Govt taxes like GST etc. (ii) Soil investigation consultant shall have Min 01 No of ME/M Tech (Geo Tech) with 2 years of experience and 01 No of BE/B Tech (Civil) with 5 years of experience and must have all adequate tech staff. (iii) Labs must be NABL accredited or any other acredition body which operates accordance with ISO/EC-170011 and accredits the labs as per ISO/MEC 17025 with the state of the art equipment apparatus. (iv) (a) Site plan duly waited with proposed buildings & bore holes in colored legend. (b) Colored site photographs of soil investigation in progress in the presence of AGE/JE indicating bore log in wooden box allied in sequence indicating bore hole number and type of stratic shall be enclosed in report.
