I would assume that the bidder has passed the bid evaluation and was determined as LCB because you are now in the post qualification phase. One of the project requirements is List of contractor’s major equipment units, which are owned, leased, and/or under purchase agreements, supported by proof of ownership or certification of availability of equipment from the equipment lessor/vendor for the duration of the project, as the case may be. I would also assume that the lease/purchase agreement were included in the submitted bid docs which will be the subject of validation/verification during post qualification.
Are the lease/purchase agreements submitted during post qualification, in addition to those submitted as part of the bid docs? If so, it cannot be a ground for post disqualification.
