Airport

Airport: Airport means an area of land or water whichis used or intended to be used for the landing andtakeo of aircraft; an appurtenant area used orintended to be used for airport buildings or other

airport facilities or rights of way; and airport buildingsand facilities located in any of these areas, andincludes a heliport.

$. (he proect de)nition period: Appraisal and strategic decisionat this time set the scene for the proect success or failure. *fthe proect is badly de)ned, or if the strategy and riskassessment are wrong, the proect will probably fail.

%. (he proect ful)llment or e+ecution period: Success now

depends greatly on the proect manager and the maincontractor. "ontractors and subcontractors with )+edcontract will think their work successful if it is )nished ontime, within budget and to speci)cation.

&. (he bene)ts reali-ation period: ow the true success or failure

of the proect will be disco#ered according to the perception ofthe proect owner and the stakeholders. /ill all the e+pectedoperational and )nancial bene)ts are deli#ered0 1ow will thewider body of stakeholders regard the performance of theproect0 "an all the borrowed be repaid on time0

(he technical re8uirement are #ague (he technical e+pectations are too ambitious

stimates of the cost, the timescale or the e+pected bene)ts are too optimistic

<isk assessment is incomplete and awed

(he intended proect strategy is inappropriate

*nsu6cient regard is paid to forecasting cash ows and the timely pro#isions offunds

(he funds re8uired cannot be made a#ailable

(here are insu6cient resources in the organi-ation to carry out the proect

(he interests and concerns of all stakeholders are not taken into account

(oo little regard has been paid to the moti#ation and beha#ior of the people who

will e+ecute the proect (he proect manager is not su6ciently e+perienced or is generally incompetent

Appro#al to proceed with the proect is gi#en for political, personal or intuiti#ereasons without due consideration of the facts and forecasts in the businessplan

Senior management fail to support the proect manager.

Airport Passenger (erminal (he passenger terminal is one of the most important elements of

the airport due to its essential role in pro#iding ser#ices to airtra#elers. (he passenger terminal must be designed to perform anumber of basic functions:

$. 7acilitate the transition of passengers between surface and airmodes of transportation

%. Pro#ide a controlled and orderly en#ironment for the processingand ow of passengers

&. "reate a secure and comfortable en#ironment for passengers to

gather and to wait, if necessary, prior to boarding the aircraft.

'. Accommodate and facilitate all of the necessary and oftencomple+ work processes with the operation and maintenance ofthe terminal facility.
