Dear Albert Peres, Look I have worked in the Govt dept as scientist in Instrumentation section, and I was dealing with the procurement of quite number of sophisticated equipment and I know how things move in the purchase sections. Suppose I want a particular item say XYZ ,and there are different types of items ( XYZ) and also different companies and they all quote as per their availability of stock. I look at my particular interest which suits me for my scientific or technical work. I put my Indent for purchases to PO and he sends me various companies quotations on a Comparative Statement form. I see the one which suits me sometimes it is not always the lowest quote then I need to give the justification for audit purpose if selected for higher quote. Say selection is made and the order is placed. Most of the Purchase officers generally have some interest ( sorry to say) i.e how to get some commission which is quite common in India. And you must be knowing being a Goan. We, as Indentors do not enter into their conflict of interest. But we see that the selected item is placed for an order. If the indentor is a corrupt person than both can get involved into it and the order is placed and the supply is received by indentor which is of low substandard non ISI quality and the materials goes to Stores dept.for compliance of stock. . So here the person/s can make money not only with his commission but on costing and certifying for a wrong supply. You see, the administrative procedure adopted in India is fishy and complicated and the public never comes to know until a doubt is created or facts are known and inquiry is initiated either on departmental basis or CBI etc. and if they are found guilty, both can face the music. Now coming to our discussion on LED supply such things can take place and I believe as per the Goa Chief Elect. Engineer the purchase order is been placed in Delhi and not in Goa.. So our Chief Electrical Engineer is not aware of the purchase order but knows that the street lights are procured and installation is in progress. . The only solution is to ask under RTI the details and check for discrepancy if any, and file a written complaint because some of the LED lamps are found flickering. That is the reason I wanted to get the purchase order of LED's supplies for Goa state, because there are different types of Street Lights LED"s and different costs and what was the selection. Even the Chief Electrical Engineer told me that he is aware and saw some wrong fittings/caps being installed at certain places and he has brought to the attention of their respective heads of the section.for correction since the lighting was not uniform according to the roads size, width etc So you see there are several discrepancies and this must be tackled by his department otherwise the public is going to suffer for bad and not uniform illumination at certain areas and at some poles there are two street lamps or bigger capacity lamp, when the road is narrow , and in some places none or one. At the moment we do not have street lamps in whole of Miramar to Dona Paula and the road is in darkness ( no visibility at all) and chances of accident is very high at night. Nobody knows when these lights are going to be installed as the monsoon is approaching. The Chief Electrical Engineer promised to look after what all I have reported. I found him extremely cooperative. I have just explained you, how we work in India and you being now in Canada may be different. Take care,
