Message to Potential Vendors OCP is pleased that you are interested in doing business with the Government of the District of Columbia. We are undergoing significant reform efforts with the goal of strengthening the District's relationship with the supplier and business communities. Suppliers can now view and search for current solicitations and subcontracting opportunities posted on this website. Also, notification of new business opportunities will be sent to all certified CBEs who have NIGP codes that match those listed on the new solicitations and subcontract requirements. In the future, suppliers will be able to respond to solicitations via the web.
