In this tutorial, I will teach you how to make an Origami Flapping Bird (really flaps!) using a regular sheet of printer paper. If you have any origami or square paper, that would be ideal to use. Making the Origami Flapping Bird is very similar to making the Origami Crane, yet with fewer folds.
invitation for bid (IFB) A part of the sealed bid process. Companies or government organizations give in-depth specifications for projects and invite contractors to bid their proposals for various projects. The sealed bids are opened at the predetermined time and recorded. A contract is awarded to the best bid.
Unilateral Contract Law and Legal Definition Unilateral contracts are one sided. In a unilateral contract, a promise on one side is exchanged for an act or forbearance on the other side. The offeror, makes a promise in exchange for an act by the offeree. If the offeree acts on the offeror's promise, the offeror is legally obligated to fulfill the contract.
