In the planning and design stages of a project, various design estimates reflect the progress of the design. At the very early stage, the screening estimate or order of magnitude estimate is usually made before the facility is designed, and must therefore rely on the cost data of similar facilities built in the past.
Ammon /am-mon/ [2 sylls.] as a boys' name is pronounced AY-mon. It is of Hebrew origin, and the meaning of Ammon is teacher, builder. Biblical: one of the sons of David. Also a place name for a country northeast of the Dead Sea.
The given name was introduced into England by the Normans, but was never as popular in England as on the Continent. In Ireland the surname originated as a form of the Gaelic O'Mordha, composed of the elements O', meaning descendant of, and Mordha, a byname translating as proud or stately. In Scotland and Wales the origination was as a nickname for a large man, from the Gaelic word mor or the Welsh mowr, both meaning great.
