Pen Drive with autocad .dwg, .pdf, .kmz/.kml file along with Satellite image photograph of desired place on desired size on hard copy as well as on Pen Drive.In case of any descrepencies with the data provided by DDA LM wing or Engineering wing with the data wrt ground survey or the list of land not found on the ground while surveying, the same shall be brought in the notice immediately. Agecy has to get the drawing verified with the concerned authorities with DDA and Delhi Govt. as desired and instructed by Engineer-in-charge. All the work shall be carried out in all aspect as per complete satisfaction and direction of Engineer-In-Charge. |
