Buildinghousesandotherstructuressuchasroads and bridgesisone of the oldestworksinthe
history.The architect,civil engineerandcontractor were meetinginone personcalledthe
builder.Itshouldbe notedthatthisgeneral ideahasexisted forthousandsof yearsanditis
representedinthe massive monumentsandmiraclesof the ancientworldsuchaspyramids.
George Wrightwrote in hisbookAncientBuildinginSouthSyriaandPalestine:“The firstreal
evidence of architectural drawingsand manual shopdrawingswasdiscoveredinthe Middle
East, specificallyinMesopotamiaandEgypt.The detailsof elevationsexisteddirectlyonplans
intoa single drawingwhichwasagreat way to maintainconsistencybetweenplansand
elevations.
Certainly,the buildingscience improveswithtime inthe usedmaterials,mechanismsand
methodsof building,designandimplementation.
Since the appearance of the computerinthe middle of the lastcentury,itsapplicationsbegan
servingbuildingscienceinvariousaspects.Afterexistence of two-dimensionengineering
programs,it improvedtoa three-dimensiondrawingwhichwasagreat step. Before using
computer,the designerredrewthe entire drawingif he neededtomodifyorcorrectan error
whichincreasesthe time of productionandthe cost.Afterthe appearance of the computer,it
has become veryeasy,fastandlow-cost.Dr.Ali Raafatsays: “Architecture nolongerneedstobe

the buildingfromatwo-dimensional imagewithdealingwiththe entire buildingthroughthe 3D
model.

of buildinginformationmodeling(BIM) appearedwhichincludedasetof techniquesandwork
methodstocreate a model of buildinginwhichall the physical andengineeringinformationof
each elementof the buildingare existed.

(If Norman Foster and Frank Gehry had practiced in ancient Greece, I imagine that they
would have worshipped very different gods. With his low-energy concerns and expertise
in using natural light).
The availabilityof informationaboutthe buildingelements,the waysof enteringthis
informationintothe computer,andthe waysof itspresentationare the mainreasonforthe
developmentof engineeringdrawingprogramsstartingfromthe two-dimensional drawingstage
passingthroughthe three-dimensional drawingstage,till the stage of buildinginformation
modeling(BIM).The information,itsvariablesandmechanismof itscontrol are the meansto
achieve the ideaof reducingtime andcost,as well asfollow-upmaintenanceof the building

the technologythatmade humansgo to the moonwithoutusingthem."
Technology has certainly influence on the work of great architects. Chris Abel says: (If
Norman Foster and Frank Gehry had practiced in ancient Greece, I imagine that they
would have worshipped very different gods. With his low-energy concerns and expertise
in using natural light).
"If the architectsNormanFosterandFrank Gehrywere inancientGreece,theirworkswouldbe
differentornot?". He answersthisquestion:"Itisclearthatthe creative thoughtof Norman
Fosterand FrankGerry distinguishedthemandIexpectedthatif theirworkswere inancient
Greece,they wouldbe distinguishedthroughhandlingspaces,innovative lightingmethodsand
external solutionstomasses."
Actually,the ideaof BIMisoldbut itsname was not BIM. Since the methodsof simulationbegan
to develop - especiallythe emergence of the computer- ,Scientistsandinnovatorsbeganto
applythismethodtovisualize the constructionprocessandsimulate itfullyinamannersimilar
to the truth, butit presentsitinadvance to provide avisual ideaof the processof buildingthe

such as overlapof huge amountsof informationof severalspecializeddepartmentslike
architectural,structural,mechanical,electrical designwithspecifications,3Ddimensions,the
cost, the schedules....andotherinformation.

Thus,BIM systemsimprovedtobecome ahuge networkwhichmovesanddirectsinformationas
theiruserswantto do a service whichthe previousgenerationdidnotdreamof.The usercan
see that everypartand everyelementof the buildingare putinitsplace inits form, size andreal
specificationsandsee itsentanglement,integrationandintersectionwith otherpartsof the
buildinginthe same chronologicalorder.Thisiswhatopensupnew horizonfordetecting
problems,clashesanddefects,thusgave the designandconstructionteamsthe opportunityto
avoidthese problemsandtoimprove the designandconstructionmethodsbefore the project
starts.
Can we considerthat BIM is the end of what man can developinthe science ofconstruction?!
Of course not,Dr. Ali Raafat says: “Our conceptionof architecture isthatitis relatedtothe
available mediumforexpressiontoconveyourthoughtstothe recipientandtothe
implementation."Thistwo-dimensional mediumbeganinthe formof plansandelevations
which are createdmechanicallyorbyhand.The documentsare submittedtothe consultantsfor
revisionandupdatingandall drawingsare withinafixedtwo-dimensional frame.All ways
become nowinadequate forillustrationandarchitecture benefitedfromthe tremendous
progressthat happenedincomputerfieldsinthe lasthalf of the 20th century.”
BIM isan important stage that doesgreatservicesthatwe shouldtake advantage of asmuch as
possible,butsciencedoesnotstopuntil Godannihilatesthe earthandwhatis on it. The more
man learns,the greaterhisperceptionincreasesandthe more he cando servicestohumanity,
and thisiswhat God wantedusto do: we shouldlearnmore toserve humanitywhen Godsaid
inthe HolyQuran:
ِ" Are those whoknowequal tothose whoknow not?”
Paul Walt, Regional Manager of Tekla Middle East, says:"Innovation in the construction industry
is undergoing a major transformation in the Middle East, and the region's mega projects such as
the World Expo 2020 in Dubai and the World Cup in Doha are opening up new horizons for
design fields. The government's mandate to expand applying Building Information Modeling
software confirms the desire of the Middle East region to be on par with the world's leading
innovation centers in the field of building and construction. Starting from Building Information
Modeling software passing through to the three- dimensional techniques software

practices that help construction and engineering companies in the Middle East to achieve
greaterinnovationandexcellence."
