1.Introduction
Hospitalbuildingprojects,areofkeyimportance,andinvolvesignificantinvestment,andusuallytakealong-termdevelopmentperiod.Hospitalbuildingprojectsarealsoverycomplexduetothecomplicatedrequirementsregardinghygiene,safety,specialequipments,andhandlingofalargeamountofdata.Thebuildingprocessisverydynamicandcomprisesiterativephasesandintermediatechanges.Manyactorswithshiftingagendas,rolesandresponsibilitiesareactivelyinvolved,suchas:
thehealthcareinstitutions,nationalandlocalgovernments,projectdevelopers,financialinstitutions,architects,contractors,advisors,facilitymanagers,andequipmentmanufacturersandsuppliers.Suchbuildingprojectsareverymuchinfluenced,bythehealthcarepolicy,whichchangesrapidlyinresponsetothemedical,societalandtechnologicaldevelopments,andvariesgreatlybetweencountries(WorldHealthOrganization,2000).InTheNetherlands,forexample,thewayabuildingprojectinthehealthcaresectorisorganisedisundergoingamajorreformduetoafundamentalchangeintheDutchhealthpolicythatwasintroducedin2008.
Therapidlychangingcontextpostsaneedforabuildingwithflexibilityoveritslifecycle.Inordertoincorporatelife-cycleconsiderationsinthebuildingdesign,constructiontechnique,andfacilitymanagementstrategy,amultidisciplinarycollaborationisrequired.Despitetheattemptforestablishingintegratedcollaboration,healthcarebuildingprojectsstillfacesseriousproblemsinpractice,suchas:

Buildinginformationmodelling(BIM)offersanintegratedsolutiontothepreviouslymentionedproblems.Therefore,BIMisincreasinglyusedasanICTsupportincomplexbuildingprojects.AneffectivemultidisciplinarycollaborationsupportedbyanoptimaluseofBIMrequirechangingrolesoftheclients,architects,andcontractors;newcontractualrelationships;andre-organisedcollaborativeprocesses.Unfortunately,therearestillgapsinthepracticalknowledgeonhowtomanagethebuildingactorstocollaborateeffectivelyintheirchangingroles,andtodevelopandutiliseBIMasanoptimalICTsupportofthecollaboration.

2.Changingrolesthroughintegratedcollaborationandlife-cycledesignapproaches
Ahospitalbuildingprojectinvolvesvariousactors,roles,andknowledgedomains.InTheNetherlands,thechangingrolesofclients,architects,andcontractorsinhospitalbuildingprojectsareinevitableduethenewhealthcarepolicy.PreviouslyundertheHealthcareInstitutionsAct(WTZi),healthcareinstitutionswererequiredtoobtainbothalicenseandabuildingpermitfornewconstructionprojectsandmajorrenovations.ThepermitwasissuedbytheDutchMinistryofHealth.Thehealthcareinstitutionsweretheneligibletoreceivefinancialsupportfromthegovernment.Since2008,newlegislationonthemanagementofhospitalbuildingprojectsandrealestatehascomeintoforce.Inthisnewlegislation,apermitforhospitalbuildingprojectundertheWTZiisnolongerobligatory,norobtainable(DutchMinistryofHealth,WelfareandSport,2008).Thischangeallowsmorefreedomfromthestate-directedpolicy,andrespectively,allocatesmoreresponsibilitiestothehealthcareorganisationstodealwiththefinancingandmanagementoftheirrealestate.Thenewpolicyimpliesthatthehealthcareinstitutionsarefullyresponsibletomanageandfinancetheirbuildingprojectsandrealestate.Thegovernment’ssupportforthecostsofhealthcarefacilitieswillnolongerbegivenseparately,butwillbeincludedinthefeeforhealthcareservices.Thismeansthathealthcareinstitutionsmustearnbacktheirinvestmentonrealestatethroughtheirservices.Thisnewpolicyintendstostimulatesustainableinnovationsinthedesign,procurementandmanagementofhealthcarebuildings,whichwillcontributetoeffectiveandefficientprimaryhealthcareservices.
Thenewstrategyforbuildingprojectsandrealestatemanagementendorsesanintegratedcollaborationapproach.Inordertoassurethesustainabilityduringconstruction,use,andmaintenance,theend-users,facilitymanagers,contractorsandspecialistcontractorsneedtobeinvolvedintheplanninganddesignprocesses.Theimplicationsofthenewstrategyarereflectedinthechangingrolesofthebuildingactorsandinthenewprocurementmethod.
Inthetraditionalprocurementmethod,thedesign,anditsdetails,aredevelopedbythearchitect,anddesignengineers.Then,theclient(thehealthcareinstitution)sendsanapplicationtotheMinistryofHealthtoobtainanapprovalonthebuildingpermitandthefinancialsupportfromthegovernment.Followingthis,acontractorisselectedthroughatenderprocessthatemphasisesthesearchforthelowest-pricebidder.Duringtheconstructionperiod,changesoftentakeplaceduetoconstructabilityproblemsofthedesignandnewrequirementsfromtheclient.Becauseofthehighleveloftechnicalcomplexity,andmoreover,decision-makingcomplexities,thewholeprocessfrominitiationuntildeliveryofahospitalbuildingprojectcantakeuptotenyearstime.Afterthedelivery,thehealthcareinstitutionisfullyinchargeoftheoperationofthefacilities.Redesignsandchangesalsotakeplaceintheusephasetocopewithnewfunctionsanddevelopmentsinthemedicalworld(vanReedtDortland,2009).
