The contracting authority may, on its own initiative, inform interested parties of any error, inaccuracy,  omission or any other type of clerical error in the text of the procurement documents.  Any additional information will be published on the above TED eTendering website. The website will be  updated regularly and it is the economic operator’s responsibility to check for updates and modifications  during the submission period 1 .
