| DIVISION 31 : SUB-SOIL INVESTIGATION WORKS & DIGITAL SURVEY | |||||||
| 2181. | Pressuremeter Test | ||||||
| 2182. | Downehole Siesmic Testing | ||||||
| 2183. | 31.1 | Mobilization and demobilization of boring equipment and man-power: at site (drilling rig comprising drilling pipe, drop hammer, tripod, pulley, chain, wrange, sample collection devices etc tools and plants; tripol for temporary camp, necessary work-force etc) (Once for one site) | per site | 14702 | 14692 | 14653 | 14653 |
| 2184. | 31.10 | Downehole Siesmic Testing- The test is to be conducted in accordance to ASTM D7400-08 to determine the interval velocities (VS & VP) from arrival times of compression (P) and shear (S) seismic waves which are generated near surface and travel down to an array of vertically installed seismic sensors. This item includes the necessary cost for entering all these data & information in necessary tables & graphs and finally furnishing them in the form of standard sub-soil investigation report with CD containing video of sub-soil investigation operation of concerned site duly signed by competent engineer & exploratory office. (Only after written advice from concerned design division/circle) | |||||
| 2185. | 31.10.1 | For first test | per test | 125541 | 125541 | 125541 | 125541 |

| 2187. | 31.11 | Mobilization and Demobilization of Heavy CPT Cone Penetrometer Equipments and Personnel Including Setting Out of Heavy CPT Penetrometer This unit rate includes the mobilisation of necessary equipments (tracks, vehicles, excavators, drill rig, CPT equipments, etc.), personnel and materials per staff to the project site for carrying out of the CPT soundings and demobilisation of the same after completion of all field works as per specification and as directed by the Engineer. The Geotechnical Surveyor must provide in the BOQ the number of staff required to perform the works. The site must to be clean after demobilisation. CPT tests shall be performed according to the ASTM D 3441 or ASTM D 5778 (Only after written advice from concerned design division/circle) | per test | 94392 | 94392 | 94392 | 94392 |
| 2188. | 31.12 | Realization of CPT Penetrometer Testing This price per linear meter covers the execution of the CPT sounding with a heavy penetrometer (20 tons minimum). This price includes: - tip and sleeve resistance, the ratio between the two, and lithologic interpretation of each 5 cm interval shall be continuously logged and can usually be printed onsite and submitted in the digital data (Excel sheet) to the client, - recordings showing the direction of the penetration of the probes and the encountered difficulties/incidents during penetration. (Max depth 35m) - This item includes the necessary cost for entering all these data & information in necessary tables & graphs and finally furnishing them in the form of standard sub-soil investigation report with CD containing video of sub-soil investigation operation of concerned site duly signed by competent engineer & exploratory office. (Only after written advice from concerned design division/circle) | |||||
