    For an Indian Railways girder tender that calls for an approved source, compare the tender's exact requirement with the current vendor record. Indian Railways directs users to the Unified Vendor Approval Module (UVAM) through the IREPS portal. A supplier's certificate or website can help locate the record.

    Start with the tender clause

    Record the tender number and the latest relevant corrigendum. Find the clause that identifies the required approved source and item or category. Note which entity must hold the approval under the tender and whether it specifies a fabrication unit, inspection authority or date by which approval must be current.

    Compare the vendor record with the offer

    FieldWhat to match
    Registered entityThe legal name on the vendor record and the fabricator named in the offer
    Approved item and scopeThe listed category and scope against the girder package and drawings
    Fabrication unitThe address or unit in the record against the shop proposed in the bid, where specified
    Status and datesThe status and relevant validity dates against the tender requirement
    Inspection requirementsThe required inspecting authority and inspection documents stated in the tender

    For example, if an offer cites a registration for composite and other steel plate girders, compare that wording against the item required by the tender. If the terminology differs or the proposed fabrication unit cannot be matched, record the discrepancy and seek a written clarification through the tender channel.

    Keep a record of the check

    Save the vendor reference, the date checked, the tender clause and the item or category you matched. Include any written clarification with the technical evaluation. Check again at the stage specified by the tender if the package or vendor details change.

    Kothari's RDSO compliance dossier lists the company's published registration for composite girders and other steel plate girders and gives buyers a starting point for the official check. Use the bridge and railway project references to assess experience separately. For the wider supplier assessment, see our RDSO approval buyer checklist.
