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.
IFC (Issued for construction) means that the drawings and specifications have been approved by the local governing agencies and that these are the plans by which the project will be constructed. Shop drawing is a drawing or set of drawings produced by the contractor, supplier, manufacturer, subcontractor, or fabricator.
