The purpose of provisions requiring that contracts with public authorities be let only after competitive bidding [is] to secure economy in the construction of public works and the expenditures of public funds for materials and supplies needed by public bodies; to protect the public from collusive contracts; to prevent favoritism, fraud, extravagance, and improvidence in the procurement of these things for the use of the state and its local self-governing subdivisions; and to promote actual, honest, and effective competition to the end that each proposal or bid received and considered for the construction of a public improvement, the supplying of materials for public use, etc., may be in competition with all other bids upon the same basis, so that all such public contracts may be secured at the lowest cost to taxpayers.
