OBJECTIVES1.1. Creation <strong>of</strong> digital map is the first step in building <strong>GIS</strong> for transmission network. GPStechnology is the best way to survey and create an accurate map <strong>of</strong> the network. Thisspecification includes proposed methodology <strong>of</strong> providing <strong>GIS</strong> <strong>Mapping</strong> using modernGPS survey techniques for GETCO’s all existing <strong>400</strong> <strong>KV</strong> & <strong>220</strong> <strong>KV</strong> transmission lines &its connected Substations. Intent <strong>of</strong> this specification is to appoint agencies to carry outGeographical Information System (<strong>GIS</strong>) mapping using modern GPS survey techniques.The field data collection for the <strong>400</strong><strong>KV</strong> & <strong>220</strong><strong>KV</strong> lines shall be given from the corporate<strong>of</strong>fice at the time <strong>of</strong> issuing A/T.2. Scope <strong>of</strong> work:The scope <strong>of</strong> work for <strong>GIS</strong> <strong>Mapping</strong> <strong>of</strong> <strong>400</strong>kV & <strong>220</strong>kV Transmission Lines & itsconnected substations using modern GPS survey techniques will be as under:(1) Before starting survey using GPS, bidder should supply & install multi userlicensed S<strong>of</strong>tware for locating <strong>400</strong> <strong>KV</strong> & <strong>220</strong> <strong>KV</strong> line towers and its connectedsubstaions on the google map.(2) To visit location <strong>of</strong> each line & its connected substaions and collect its coordinates.Every 5 kms. Of line or part there <strong>of</strong> 1 no. nearest permanentstructure, identification, latlon should be taken & locate the same on topo-Sheet.(3) Plotting <strong>of</strong> collected co-ordinates on map.(4) Superimposing <strong>of</strong> route map <strong>of</strong> line & Location <strong>of</strong> Sub station on topo-sheet.(5) The successful bidder shall supply 5 nos. <strong>of</strong> GPS instruments free <strong>of</strong> cost <strong>of</strong>the specifications superior or equal to specifications given as per attachedsheet A. Also bidder has to provide demonstration & training <strong>of</strong> GPSinstrument as per the requirement <strong>of</strong> GETCO. The instrument should havefollowing essential features:(a) Capability <strong>of</strong> receiving minimum satellite signal – 12 nos.(b) Accuracy: - All co-ordinates are to be measured with accuracy <strong>of</strong> betterthan or equal to 3.0 meter by GPS.(c) Memory capacity: 128 MB RAM(d) Compatible to various s<strong>of</strong>tware like AutoCAD, PLS CADD along withZOOM feature.(e) In built maps for navigation purpose.(f) All accessories to up load & down load documents.Seal & Signature <strong>of</strong> Bidder4

The description given here is broad scope <strong>of</strong> work to be carried out by thecontractor. However, any work even if not specifically mentioned but reasonably impliedfor the successful implementation and good performance <strong>of</strong> the system are deemed tobe included.The scope <strong>of</strong> work <strong>of</strong> the bidder shall include following but not limited to:1. Bidder shall prepare the coding <strong>of</strong> all <strong>400</strong> & <strong>220</strong> <strong>KV</strong> S/s & its line & get approvalfrom GETCO.2. Updation <strong>of</strong> Network and Transmission Line added to it during projectimplementation phase and thereafter up to One year is to be done.3. The GPS Survey is to be carried out <strong>of</strong> each <strong>of</strong> the Tower <strong>of</strong> <strong>400</strong>kV and <strong>220</strong> <strong>KV</strong>Transmission Lines & its connected sub stations comprising <strong>of</strong> approximately31600 Towers.4. Surveyors shall walk along the each locations <strong>of</strong> transmission lines with a GPSrover & capture the co-ordinates <strong>of</strong> the location (Tower). Wherever the linecrosses the <strong>400</strong> <strong>KV</strong> line, Railway line, Express highway, National Highway, thecontractor shall record co-ordinates on the points <strong>of</strong> crossing, wherever line routepasses over permanent land marks.5. During the Physical survey, the concern <strong>of</strong>ficer <strong>of</strong> the GETCO related to theconcern line being surveyed will guide the contractor for identification <strong>of</strong> theTowers nearby to the entry / exit <strong>of</strong> the line from the respective Sub Station. Theintermediate Towers where only one line is there, the contractor has to completethe survey based on the guidance provided by the concerned GETCO <strong>of</strong>ficer.Wherever multiple lines are combining or crossing, the GETCO <strong>of</strong>ficer will guidethe contractor for identification <strong>of</strong> the each <strong>of</strong> the Tower <strong>of</strong> each <strong>of</strong> the Lines, asper the timing schedule. The contractor has to keep continuous liasioning withthe concerned GETCO <strong>of</strong>ficer so that he is available for providing guidance foridentification <strong>of</strong> the Towers. The contractor will be provided with all the details <strong>of</strong>the Transmission Lines to be surveyed and the contact details <strong>of</strong> the respectiveGETCO <strong>of</strong>ficers <strong>of</strong> the respective lines so that maximum co-ordination can beachieved and the survey can be completed without any errors and in thestipulated time.6. The complete job is to be completed within 10 months from the date <strong>of</strong> issuance<strong>of</strong> AT. The request for extension <strong>of</strong> the completion time will generally will not beentertained however, if the reasons are justified and written request is received,the extension may be granted if the GETCO <strong>of</strong>ficer is satisfied with the reasonsgiven to him. The decision <strong>of</strong> the GETCO <strong>of</strong>ficer regarding this will be final andbinding to the contractor.7. The contractor has to submit the reports for completed work for the number <strong>of</strong>lines every month. The bidder shall collect work completion certificate (WCC)with number <strong>of</strong> locations carried out, Name <strong>of</strong> line & Name <strong>of</strong> S/s from theExecutive Engineer (Telecom), corporate <strong>of</strong>fice. The payment will be made within60 days on pro-rata basis based on the work completed during this 1 month.8.
