The design of Benoy Architectssucceeded in creating a buildingexpressing all the emotionsand values which raised Ferrari toiconic status during the last fiveyears. The dynamic, aggressivedesign of the roof evokes associationswith the flowing lines typicalfor the body of a Formula 1 Ferrari.Ferrari World is covered by agigantic free-formed roof witha covered area comparable tothat of half of the Vatican Stateor to approx. 40 soccer fields.The complete roof structure witha surface of almost 200,000 m²consists of a MERO KK spaceframe structure. With a total ofapproximately 172,000 membersand 43,100 nodes, this is thelargest space frame structureever built worldwide.The total building is composed offunnel, shield and triforms. Theso-called shield with a surface of86,200m² is the big central structure,with a maximal diameter of377 m, surrounded by façades. Atthe heart of the shield, the imposingglazed funnel catches the eye.With a total surface of 9,440 m²,it measures 100 m in diameterat the point where it penetratesthe roof of the shield and tapersto a diameter of 18 m at groundlevel. The three open triforms ofthe periphery extend the centralshield in star-shape and coveran area of approx. 100,000 m².Starting as mere extensions ofthe shield, each triform splits intotwo prongs when they reach athird of their total length, andthey end in three-dimensionalcurving tips at a maximal distanceof 284 m from the shield.The space frame structure itselfis subdivided in double layerareas and three layer areas. Thetrusses themselves have beenconstructed as three layer spaceframe structures, and they havebeen directly integrated in thedouble layer roof structure, whichgives the steel structure of theroof its harmonic character.At a level of 18 m to 32 m, the roofstructure of the shield rests on aminimum of axially positionedrows of columns. In the middle,twelve central space framecolumns symmetrically surroundthe funnel. The square bases splitat half height into two opposedarches which blend seamlesslyinto the three layer girders of theroof structure. In their final state– completely cladded – theyare reminiscent of the pointedarches of medieval cathedrals.Funnel, shield and the threetriforms are statically independent.That means that the steelstructure of Ferrari Worldis subdivided into five separatebuildings. The layout of the spaceframe grid in the area of theshield was optimized in termsof size and dimensions, minimizingthe individual constructionelements and costs. At the sametime, the generous grid size andthe predominantly small memberdiameters create the impressionof a surprisingly airy structure.The start of the Formula 1 racein Abu Dhabi on November 1st,2009 set the deadline for thecompletion of the project. This ledto further heavy demands on theorganisation of the production,logistics and installation process.Not unsurprisingly for a projectof this enormous size, the projectmanagement had made verystrict requirements regardingHealth & Safety, which MERO-TSKobserved and enforced. Withoutany working time lost due toaccidents MERO-TSK had its fairshare in the nomination for “Winnerof the Best Achievement in<strong>Construction</strong> Health & Safety 2008”which Aldar Properties PJSC – YASIsland Projects was awarded bySHP IOSH.Part of MERO-TSK’s philosophy isto achieve the fullest satisfactionof clients and partners with highquality solutions and distinctivedesign. Ferrari World is anexcellent illustration of this.The key data of this project readlike a list of superlatives, and thedemands on production, logisticand erection as well as the extremedeadline pressure touched onthe outer limits of the technicallyfeasible. But thanks to decades ofexperience in the field of elementizedbuilding systems and thanksto the absolute dedication of thewhole team, MERO-TSK has onceagain realized a unique milestonein the history of architecture.Architekt/Architects: Benoy, LondonBildnachweis/Photo Credit:Aldar Besix, DubaiFotograf/Photographer:Chopper Shot, SharjahScience & Technology ParkBei der Erweiterung des „Veil“handelt es sich um eine kontinuierlicheFortführung des bereits bestehendenDachs für die Verschattungdes angrenzenden „General Electric- Advance Technology ResearchCentre“ (GE-ATRC). Das Freiformdachder ersten Phase mit einer Grundflächevon ca. 19.650 m² wurde damitum weitere 3.630 m² vergrößert.Wie bereits für die vorangegangenen38.000 m² des „Veil“ wurdenauch für dessen Erweiterung diezusätzlichen 8.315 m² der Ober- undUnterseite des Dachs und der Stützenmit Paneelen aus hochkorrosionsbeständigemEdelstahl verkleidet.Das Design der „Car Park Shades“,die zu beiden Seiten des „Veil“ denBereich der Parkplätze überdachen,entspricht dem des Hauptdaches.Auch hier basiert die Konstruktionder beiden, je 2.040 m² großen Dächerauf einer MERO-Raumfachwerkstruktur,die über das neuentwickelteund patentierte Befestigungssystemmit Edelstahllochblechpaneelen eingedecktist. Wie beim „Veil“, handeltes sich auch bei den Dreieckspaneelender „Car Park Shades“ aufGrund deren Freiformgeometriefast ausschließlich um Unikate.Auch für die Verkleidung des „ICBuilding“, dem Bürokomplex für dieZentralverwaltung und das BusinessCenter unterhalb der Ost-/Westachsedes „Veil“ kam der hochwertigeEdelstahl zum Einsatz. Werden diebeiden Glasfassaden an den Kopfseitendes „IC Building“ durch das„Veil“ überdacht, so schützen an dessenLängsseiten Fassaden aus insgesamt3.300 m² Edelstahllochblechendie beiden dahinterliegenden Glasfassadenvor der direkten Sonneneinstrahlung.Neben den umlaufendenGlasfassaden bestehen die restlichen10.900 m² der Gebäudeeindeckung,aus Edelstahl-Glattblechen, die ringsum die Gebäudeseiten, -ecken unddessen Untersicht verlaufen. Ein besonderesFeature stellt die Verkleidungder Sekundärstahlstruktur inden Eckbereichen des „IC Building“dar. Um die vorgegebene, doppelgekrümmteOberflächengeometrie zuerhalten, wurde in einem aufwendigenExplosionsverformungsverfahrenjedes dieser Bleche einzeln in seinejeweils individuelle Form gesprengt.The ”Veil” extension consists of aseamless addition to the alreadyexisting roof in order to provideshade for the adjacent “GeneralElectric - Advance TechnologyResearch Centre” (GE-ATRC).The free form roof from the firstconstruction phase with approx.19,650 m² was thus enlarged byanother 3,630 m². As was alreadythe case with the 38,000 m² totalsurface of the “Veil”, the additional8,315 m² of the top and bottomsides of the roof and columns werecladded with panels of highlycorrosion-resistant stainless steel.The design of the “Car Park Shades”over the car park areas on bothsides of the “Veil” corresponds tothat of the main roof. Here, too, theconstruction of the two roofs (eachwith a surface of 2,040 m²) is basedon a MERO space frame structurewith a cladding of perforatedstainless steel sheet panels whichis secured with a newly developed,patented fixing system. ComparableDohaQatarto thesituationof the“Veil”cladding, the individual triangularpanels of the “Car Park Shades”are almost all unique in shape as aresult of the free-form geometry.The same special stainless steel wasalso employed for the cladding ofthe “IC Building”, the office complexof the central administrationand the business centre under theeast-west axis of the “Veil”. Whilethe “Veil” shades the two glazedfacades at the front of the “ICBuilding”, along the flanks of thebuilding facades covered with 3,300m² perforated stainless steel sheetsprotect the two glazed facadesbehind them from direct sunlight.Besides the surrounding glazedfacades, the remaining 10,900 m² ofthe building envelope are made ofplain stainless steel sheets runningalong the sides and corners of thebuilding and along its underside.The cladding of the secondary steelstructure in the corner areas of the“IC Building” is a special feature.The design envisaged by thearchitect necessitated a special productionprocess. In order to achievethe required double bent surfacegeometry, each of the sheet metalpanels had to undergo a complexprocedure of forming by explosionto give it its individual shape.Architekten/Architects:Woods Bagot, Abu Dhabi7
