| 1 | Carrying out topographical survey of rivers, drains, canals, roads, etc., using Total Station, DGPS, or approved modern techniques (excluding drone surveys) at 5m x 5m intervals or as directed by the EIC. Includes chaining, ranging, leveling, site clearance, and referencing to approved BM/TBM. Rate includes submission of raw data and processed PDF/soft copy reports, covering all costs of labor, machinery, mobilization, and incidentals complete as per EIC's direction. | 1.000 | Ha |
| 2 | Carrying out topographical survey of rivers, drains, canals, roads, etc., using Total Station, DGPS, or approved modern techniques (excluding drone surveys) at 10mx10m intervals or as directed by the EIC. Includes chaining, ranging, leveling, site clearance, and referencing to approved BM/TBM. Rate includes submission of raw data and processed PDF/soft copy reports, covering all costs of labor, machinery, mobilization, and incidentals complete as per EIC's direction. | 1.000 | Ha |
| 3 | Generation and submission of contour plans at 0.5m (or required) intervals from available survey data in digital format. Work includes superimposing contour data onto base maps, satellite imagery, or other reference documents as specified by the EIC. | 1.000 | Ha |
| 4 | Generation and submission of longitudinal sections (L-sections) and cross-sections (X-sections) from available survey data at required intervals and lengths using industry-standard engineering software. The scope includes data processing, CAD drafting, and submission of geo-referenced digital files (e.g., .DWG and .PDF), inclusive of all labor, software licensing, and incidental costs. | 1.000 | km |
| 5 | To carry out sub-soil exploration by appropriate methods for soft, medium, and hard soils, and soft/hard rock to collect disturbed and undisturbed samples from required depths. The scope includes conducting all necessary laboratory testing of the samples at GERI or a Government-approved laboratory. This item is all-inclusive of machinery mobilization, labor, transportation, operational charges, and the actual laboratory testing fees/invoices from GERI or the approved Government laboratory. The contractor shall provide a comprehensive geotechnical investigation report based on the exploration, including detailed bore logs, Core Recovery, RQD/RMR for rock, settlement calculations, and foundation recommendations complete in all respects. | 1.000 | Rmt |
