3.3.3 Single Stage Two Envelope Systems (1S2E) In technically complex requirements but where capability of source of supply is still not crucial and value of procurement is not low, a two envelope system may be followed:

i) If required, Technical specification and techno-commercial conditions may be modified, after the pre-bid conference in the two envelopes. The pre-bid conference is to be organised before the bid submission date. It may be necessary to issue the prebid conference minutes to all participants/ upload to the web-portals and some revised RfQ/ RfP documents where necessary. ii) The tenderers should be asked to bifurcate their quotations in two envelopes. The first envelope, called the techno-commercial bid, contains the eligibility, technical quality and performance aspects, commercial terms and conditions and documents sought in the tender, except the price and relevant financial details. In the second envelope, called the financial bid, the price quotations along with other financial details are submitted. Both the envelope are to be submitted together in a sealed outer envelope, as it would not be desirable to invite financial bids after opening of techno-commercial bids; iii) The techno-commercial bids are to be opened in the first instance on the bid opening date and time, and scrutinised and evaluated by the tender committee (TC) with reference to parameters prescribed in the tender documents and responsive, eligible and technically compliant bidders are decided; iv) Thereafter, in the second instance, the financial bids of only the techno-commercially compliant offers (as decided in the first instance above) are to be opened on a preannounced date and time for further scrutiny, evaluation, ranking and placement of contract. The financial bids of technically non-compliant bidders should be returned unopened to the respective bidders by registered acknowledgement due/ reliable courier or any other mode with proof of delivery. In e-Procurement, financial bids of technically non-compliant offers would not get opened;

3.3.2 Single Stage Single Bid/ Envelope System (1S1E) Where it is feasible to work out the schedule of quantities and to formulate detailed specifications for Works and capability of contractor isn’t critical and value of procurement is low or moderate, the single envelope system may be adopted, where eligibility, technical/ commercial and financial details are submitted together in the same envelope. This is the simplest and the quickest bidding system. The lowest responsive priced bid that meets the eligibility criteria, technical and commercial requirements laid down in the bid documents is declared as successful and awarded the contract.

3.3.4 Single Stage Multiple Envelope System (with post-qualification, 1S3E) As discussed below, where the procurement is moderately complex and the time, effort and money required from the bidder to participate in a tender is not very high, instead of a separate stage of Pre-Qualification bidding (as described below), a clear-cut, fail-pass qualification criteria can be asked to be submitted as the first (additional) envelope in a three envelope single stage bidding, so that a bidder's risk of having his bid rejected on grounds of qualifications is remote if due diligence is exercised him. Strictly speaking, this is not a prequalification but a Post-qualification of bidders (as in case of Single Envelope and Two Envelope Bidding). In the first instance on the bid opening date only the post-qualification envelope (also containing the EMD and other eligibility documents) is opened and evaluated to qualify the responsive bidders who pass the post-qualification. Rest of procedure is same as two envelope system for only qualified bidders. Rest two envelopes of unqualified bidders are returned unopened to the respective bidders by registered acknowledgement due/ reliable courier or any other mode with proof of delivery;
