Rashtriya Chemicals And Fertilizers Limited Tender

Taking bores for subsoil investigation through overburden and soil / rock of all sorts including providing of temporary casing and cleaning the bottom of holes before conducting field tests or collecting samples at various depths etc. complete as specified and directed. Borehole to be drilled maximum up to 12.0 m depth as per site condition below existing ground level. The investigation includes following: 1. Boring 100 mm dia boreholes through all type of soils up to Rock surface. 2. Drilling through rock using Nx size (76mm) with double tube core barrel fitted with diamond studded drill bit. 3. Collecting disturbed soil samples in overburden. 4. Conducting standard penetration tests (SPTs) in bore holes at regular interval of GE 1.5 m. 5. Conducting all laboratory tests (Plz check NIT) i) Standard penetration test ii) Specific gravity iii) SBC determination at every 3m depth iv) Natural moisture content v) Hydrometer analysis vi) Tri axial Compression tests vii) Liquid and plastic limit viii) Chemical analysis, Suphates, chlorides, PH ix) Porosity, density and specific gravity test on rock x) Soaked crushing strength of the rock. 6. Collecting undisturbed samples (UDS) 7. Arranging all soil samples and rock cores in the core boxes. 8. Transporting the selected samples and water samples to lab for conducting specific tests. 9. Analysis and interpretation of field and lab tests data for preparation of Geotechnical report. 10. Calculation of SBC at every 3m depth. 11. Submission of reports with recommendation.

To carry out topographical survey of the proposed open plot (size 50mx50m approx.) for 'HRSCC Project' with total station instrument as diercted anywhere inside factory premises with reference to existing co-ordinate system by establishing control stations by establishing temporary bench mark from permanent bench mark, marking the traverse on open plot by nails, carrying out detailed levelling at a longitudunal and lateral interval of 5m(i.e. forming grid of 5mx5m), plotting cross sections, cross distance, preparing drawings on AutoCAD, Bore hole locations within site area , Reduced levels (RL), Northing and Easting Co-ordinates and submission of hard and soft copies of drawings etc. as directed by EIC.
