The tender lists 6 items across a broad scope, with an EMD of ₹28,495. Location details are not specified in the document. The procurement aims to source standard, OEM-identified parts that integrate with NMDC mining infrastructure, requiring precise drawing compliance and compatibility with existing assemblies. The absence of listed technical specs indicates reliance on accompanying specification documents and ATC terms for exact compliance. Unique clauses include quantity variation up to 25% during contract execution and delivery timelines linked to the original order date. This setup necessitates bidders with robust supply chain, engineeering support, and track-chain assembly experience. The essential differentiator is the combination of multiple heavy-duty components under one tender, with explicit option-based quantity adjustments and ATC attachments.
