Participation is restricted to contractors enlisted as eligible bidders with NVVN. Participants must also qualify as Class-I or Class-II local suppliers under the tender requirements. All bidders are required to conduct a mandatory site survey before submitting their offers and provide an undertaking on company letterhead confirming the visit. Failure to submit the undertaking may lead to rejection of the bid. Each bidder must furnish an Earnest Money Deposit (EMD) of Rs. 1 mn as bid security. The amount may be submitted through electronic fund transfer or an electronic bank guarantee using the National e-Governance Services platform. The available tender information does not specify a separate Performance Bank Guarantee amount, so bidders must consult the complete bidding documents for the applicable performance security provisions.
