BID DOCUMENT NO. ADPL/DL/EPC/01 1750MW DEMWE LOWER ...

Comments:
Based on the feasibility route survey our observation & conclusion are as follows:
Lower Demwe Project:
� The Road from Dibrugarh to Rupai (Total distance 80 KM) we are travelling on NH – 37. The road is in good condition having
carriage width 6.5 M & clear width of road is 7.5 M.
� From Rupai to Parshuramkund (Total distance 133 KM) we are travelling on NH-52. The road is in good condition. At many
places road is narrow having carriage width – 3.5 M but clear width of the road is 7 M & the entire NH-52 is under planning
for widening for which road widening is under construction.
� It was observed that up to DEMWE LOWER (Parsuramkund) all bridges are RCC (70 R) with clear width of 7.5 M or more
which are capable to take 125 MT cargo weight plus vehicle weight.
� It was observed that at Tinsukia (52 KM) we have to pass under the Overhead Bridge for which height restriction is 6 M from
ground level.
Conclusion:
From logistics point of view we conclude that cargo upto 125 MT (excluding Trailer) in weight, 12 M in length , 6 M in width & 6 M in
height including vehicle on 10 axles hydraulic trailer can move safely & smoothly up to Lower Demwe Project Site.
Upper Demwe Project:
� The road stretch between Lower Demwe & Upper Demwe is around 70 KM but having plenty of restriction all along the
route. The present road condition is very bad. The entire route is in forest hilly region having very narrow road, short turning
radius, steep up & down gradient. Most of the bridges are steel constructed & very weak. Further one bridge on Tiding river
(40 KM) which is hanging suspension bridge with restriction of only 9 MT weight. (Details are attached with distance chart
report.)
Conclusion:
We feel that as on date it is not possible to carry any cargo which is more than 3 M wide & weight 9 MT including vehicle.
After having detailed analysis of this route , we strongly recommend to explore possibility of using barge between Lower Demwe &
Upper Demwe, once the dam at Lower Demwe is filled, so that heavy equipments like runner, transformer & ODC cargo can safely &
timely mobilize up to the Upper Demwe Project Site.
