All tenders are advertised in the print media and website and there is no restriction on who may submit a tender. Open tenders published in the print media and the website are usually held open for a predetermined period of between two and four weeks depending on the complexity and amount of work done by prospective bidders. Closing time for all tenders is normally at 12:00 on the closing date. A late response is not permitted for consideration and is returned to the bidders with an explanation.
