If you were one of the bidders, you have to raise your allegations to the tenders committee (which is by the way comprise of members from different government entities including the ministry of finance and Audit bureau). Audits are usually conducted only after tenders are awarded by each entity's internal audit department in cooperation with the audit bureau. Witnessing how much effort is taken in implementing those measures lately, I'd say we are undisputedly the least corrupted in the entire region.
