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.
A contract may be express or implied. An express contract is one, whose terms are stated in words. An implied contract is one, the existence and terms of which are manifested by conduct. A unilateral contract is one in which there is a promise to pay or give other consideration in return for actual performance. bilateral contract is one in which a promise is exchanged for a promise. In most cases contracts can be either written or oral, but oral contracts are more difficult to prove and in most jurisdictions the time to sue on the contract is shorter.
