Military Engineer Services Tender

Hiring and mobilization of drilling equipments, instruments, plant etc all as specified and directed.

Boring 02 bore hole through all kinds of soil/ rocks upto a depth of 15 mtrs below ground level or upto hard strata (whichever is greater) collecting samples and conducting necessary field and laboratory tests. Following parameters will also form of Geo-Exploration report to be submitted. (a) RL of the Ground level/ founding level with reference to a BM should invariably be mentioned in the soil investigation report. (b) Physical and chemical properties of soil. (c) SPT N value at every 0.75m intervals and change of strata. (d) Grain size distribution and analysis including soil characteristics. (e) Value of cohesion and angle of internal friction. (f) Depth of expansive soil and its properties. (g) Recommendations for type of foundation. (h) Recommended SBC based on N value, shear and settlement criteria at three depth 1.5m, 2.0m, and 2.5m and should be worked out for following sizes of footings. (i) 1.5 x 1.5m (ii) 1.5 x 2.5m (iii) 2.0 x 2.5m (iv) 2.0 x 3.0m (v) 2.5 x 3.0m (j) Photographic record of Geo-Exploration as well as testing shall also form part of the report. (k) Recommendation as regards possibility of liquefaction of soil in case of saturated or partially saturated loose/ uncomacted sandy soil. (l) Swelling index and swelling pressure in respect of Black Cotton soil and its depth / layer. (m) Depth of ground water table (maximum and minimum) (n) Recommendation for filling under floors. (o) Details of soil profile and bore logs (p) Any other recommendations. Note: The report along with recommendations shall be submitted in duplicate.
