Open Competitive Bidding

Business Guide | June 2018

Open competitive bidding consolidates the competitive procurement of goods, works, and services (both nonconsulting and consulting services) under a single procurement method.

With open competition a key principle in ADB operations, open competitive bidding is ADB’s preferred procurement method. It consolidates the competitive procurement of goods, works, and services under a single procurement method. This method facilitates open competition among all eligible bidders, regardless of whether procurement contracts are advertised internationally or nationally. Its defining feature is effective and appropriate advertising to provide as many qualified bidders as possible equal opportunity to bid for contracts. This guidance note advises borrowers on best practices in implementing this method for projects financed in whole or in part by an ADB loan or grant, or by ADB-administered funds.
