DfID restarted the procurement process to identify a suitable Design, Build and Operate (DBO) contractor in October 2006. Capability Statements were received by DfID in March 2007 and four bidders were pre-approved for the DBO contract and a further three applicants have been pre-approved for the Air Service Provider contract. The applicants for the DBO visited the island for six months from June 2007 before submitting their final proposals, and by January 2008 DfID was down to a shortlist of two bidders.
