Important Notes: 1) The quoted rates shall be inclusive of all taxes, cost of labour, materials, equipment and preparation of report & drawing if any, proper completion of the work. 2) No escalation is admissible/payable for this work in any case. 3) Cost quoted shall include liasioning with concerned authorities etc. required for completing the job. 4) No separate payment shall be made for mobilization, demobilization, data processing, or reporting — all shall be deemed included in the unit rate. 5) Contractor shall ensure safety and confidentiality of RRCAT installations and comply with campus security protocols. 6) The agency shall obtain necessary entry permissions and follow site safety procedures at all times.

Conducting detailed topographical survey and submitting report using Total Station and/or DGPS or equivalent surveying instruments, covering the following scope:

(i) Carrying out apex-to-apex traverse and capturing all salient features such as permanent structures, roads, culverts, pipelines, drains/nalas, fire line, electrical poles (LT/HT/EHT), underground LT/HT lines/cables, transformers, septic tanks, STP, WTC, communication cables, OFC, water supply lines, sewer lines, chambers, manholes, worship places, water bodies/ lakes and all vegetation including trees having girth greater than 30 cm, specifying the girth and type/species of each tree, underground services as guided by departmental representative etc. Determining depth of bottom of water bodies/ lakes and volume of water at Full Reservior Level (FRL) by appropriate method including provision of boat (as required). Establishment of true north at site, calculation of the total campus area and its major divisions, as directed by the Engineer-in-Charge.

(ii) Recording ground levels at 5 m × 5 m grid spacing in plain areas and 3 m × 3 m grid spacing in foothill/undulated areas, and preparation of drawings in CAD (dwg) and GeoPackage formats compatible with QGIS software specifying the co-ordinate reference system used.

(iii) Plotting contours at 1.0 m depth interval and preparation of contour maps in CAD (dwg) and GeoPackage formats specifying the co-ordinate reference system used.

(iv) Submission of following drawings/report: a) Contour map indicating boundary. b) Map showing all salient features as mentioned above including calculation of area(s). c) Map showing all vegetation and trees with girth more that 30 cm. d) Survey Report e) Survey map and report of Indus-3 (HBSRS) site within the RRCAT campus as directed by Engineer-in-Charge Above listed drawing/report shall be submitted as follows: Three (03) hard copies and soft copy of the signed survey report along with three (03) set colour drawings (A0 size) — out of which one set on ammonia/print paper — and soft copies of all CAD files, raw data, and processed files in a USB/pen drive, as directed by the Engineer-in-Charge.

(v) The scope also includes transferring the Permanent Benchmark (PBM) to required locations from already established GTS Benchmarks of Survey of India, and superimposing the newly prepared topographical drawings over existing RRCAT drawings, if required.

Instrument Accuracy and Coordinate System: a. Total Station: minimum angular accuracy 5″, distance measurement accuracy ±2 mm + 2 ppm. b. RTK DGPS/GNSS: positional accuracy ±10 mm horizontal, ±20 mm vertical. c. All coordinates shall be provided in WGS-84 datum using UTM Projection – Zone 43N (EPSG:32643) and/or local RRCAT grid, as instructed by the Engineer-in-Charge.

Supply, fixing, and construction of reference/grid pillars: Providing and constructing M30 Grade Reinforced Cement Concrete (RCC) pillars with minimum dimensions 300 × 300 mm (as per tender drawings) at every 100 m interval, at changes of angle, and at other locations as required by site conditions and as directed by the Engineer-in-Charge. The work shall include all labour, transportation, excavation, backfilling, shuttering, concrete placement, vibrating, curing, and fixing the pillar in earth, Exterior-grade painting with primer and engraving & marking on the pillars over SS 304 plate etc. complete as per specifications and as directed by EIC. The cost includes all labour, transportation, excavation, backfilling, concrete work, paintingand finishing, complete as per specifications and as directed by the Engineer-in-Charge.

The GPR survey shall be conducted in coordination with the topographical survey, ensuring all detected utilities to be precisely geo-referenced and reflected on the topographical base map in CAD and Geopackage format.

Preparation and submission of deliverables, including: i. Base map showing surveyed area and GPR scan lines. ii. Plan showing identified utilities with coordinates, depth, and type. iii. Radargrams and interpreted sections. iv. Technical report detailing methodology, equipment used, and interpretation summary v. Digital data in CAD (.dwg) and GIS-compatible formats (geopackage), aligned with campus coordinate system vi. Hard and soft copies of the final utility mapping report.
