Please parahrase "Based on the available information under survey, ABC conducted post-tender closing clarifications with two tenderers      (Case 2) and one tenderer (Case 3) in relation to the arithmetical errors on the total estimated amounts of the items.  In fact, the post-tender closing clarifications with the three tenderers were unnecessary since such calculation errors did not affect the overall rankings of the three tenderers and all other tenderers irrespective of adopting the original or the corrected estimated contract prices.  Besides, instead of stating the detail and reason for the post-tender closing contact, the TAP wrongly stated in the tender report that no clarification had been made with tenderer (Case 3)."
