Bidding.
Section 4
SEC. 4. Bidding.—Construction projects shall generally be undertaken by contract after competitive public bidding. Projects may be undertaken by administration or force account or by negotiated contract only in exceptional cases where time is of the essence, or where there is lack of qualified bidders or contractors, or where there is a conclusive evidence that greater economy and efficiency would be achieved through this arrangement, and in accordance with provision of laws and acts on the matter, subject to the approval of the Ministry of Public Works, Transportation and Communications, the Minister of Public Highways, or the Minister of Energy, as the case may be, if the project cost is less than P1 Million, and of the President of the Philippines, upon the recommendation of the Minister, if the project cost is P1 Million or more. A bidder's bond, in an amount to be established in accordance with the rules and regulations to be promulgated pursuant to Section 12 of this Decree, shall accompany the bid to guarantee that the successful bidder shall, within a prescribed period from receipt of the notice of award, enter into contract and furnish the required performance bond for the faithful and complete prosecution of the work specified in the contract documents.
