This is associated works contract as part of doubling project for 14km only and tender value is Rs 15cr time period of completion is 18 months. So actual doubling works contract is diffrent as you mentioned but my doubt is why have given tender for only 14km in place of EPC contract for 40-65km by calling national tenders in which big construction companies will participate as done by NHAI. Last year when I saw third line work in Tenali Sinyarayakonda section couldn't find automatic track laying machines any where .
