DGPS Survey and physical verification of land of NTPC Dadri

Amount

DGPS Survey of NTPC Dadri project

Detailed survey (door to door) and report on land parcel/colonies under unauthorized encroachment as per format given in Table-C of Appendix-II. Marking/Showing the encroachment area, if any, separately on the AutoCAD drawing as well as Google earth Map (Kmz files). (Note: Payment against this item shall be made for the area actually found to be already encroached, while carrying out survey against the above item and agreed upon by EIC)

Topographical Survey: Detailed survey of project area earmarked, Marking identification marks of all the existing visible structures / features like buildings, roads, drains, pipe-racks, stacks, tanks, dyke, water reservoir, water channel, coal stock, stadium, open area, green area, electric, telephone line with poles, sheds, temples, ground coverage, boundary walls, tree, manholes and any other structure etc in Auto CAD Drawing. Calculating actual area of plot and marking boundary line and showing breakup total area as per land use pattern viz. buildings, parks, roads, railway line, pipe corridor, reservoir,green belt, ash dyke, open space etc. for the whole area, where detailed survey to be done as per format given in Table-D of Appendix-II. Taking spot levels/plinth levels of existing building, and height of any other prominent structure, internal and adjoining roads level, culverts, Manholes etc & marking the reduced levels on the survey drawings/reports. The report should include details of built-up units and measuring the plinth area in tabular form and correlating with the correspoding structure marked in drawing.

Cadastrial Survey: Area survey of whole Project area (viz. Plant, Townships, Ash Dyke, Railway Corridor, Ash pipe corridor etc. separately as per identification/ location), Marking DGPS co-ordinates & levels of at interval of 100 m or part thereof and corners (of bend 60 degree or less) along the boundary line & as per instructions of Engineer-in-Charge (EIC), through DGPS equipments as per specification in Appendix 1 or combination of DGPS and Total Station . To collect details of Khasra / Khatoni maps from revenue authorities and plot the same on the revenue map ( as converted digitally before start of survey). The same has to be modified putting the boundary line of area in occupation, as also area in adverse possession after completion of survey. These areas have to be color coded seperately on the basis of: I. Type of land wise( Private, Govt.,Forest,Departmental, Direct purchase ). II. Possession( Land in possession of NTPC,adverse possession) III. utilization wise ( main plant, ash dyke,township etc). In addition, area chart capturing the details of following has to be prepared as per format given in Table- A of Appendix-II: I. Type of land wise( Private, Govt.,Forest,Departmental, Direct purchase). II. Possession( Land in possession of NTPC,adverse possession) III. utilization wise ( main plant, ash dyke,township etc). Preparing & submitting a comparative statement of land as per Acquisition plan & actual physical possession in a tabular format & highlighting excess/shortfall/encroachment area, and as per format given in table-B of Appendix-II. Preparing and submitting Auto CAD drawing/reports and shape/Kmz files etc. as per technical specifications /requirements (clause 2 to 11) and as per instructions of engineer-in- charge (EIC). In addition all the survey details are to be superimeposed upon latest google earth map alongwith Kmz files for area of utilization wise viz main plant, Ash Dyke etc. with the composit superimeposed map for the entire project.

Construction and installation of permanent reference PCC pillars(1:2:4) (Size 400x400x750 mm depth with additional tapering at the top upto 150 mm above(450 mm below ground level)) of approved specifications & drawings (Appendix-IV) and at interval of 100 m and part thereof and corners ( having bend of 60 degree or less), including necessary excavation and backfill, as per direction of Engineer-in -charge. These Pillars shall be labeled permanently with their identification marks, respective GPS coordinates and reduced levels for future use alonwith NTPC name engraved on it. The pillars should be painted with synthetic enamel.The pillars shall also be shown on the survey drawings/Google Earth. (Note: All materials & labour for this work shall be arranged by the surveying agency)
