Ellis ten Dam - Royal HaskoningDHV

Ellis ten Dam is in januari 2013 toegetreden tot het CoreNet Benelux bestuur. In de eerste periode coördineert ze vanuit CoreNet Benelux het Onderzoek naar gebruikerswensen, dat voortkomt uit het Convenant Leegstand Kantoren. Het onderzoek moet de aanbieders inzicht geven in de eisen van de gebruikers zodat er een kantorenmarkt ontstaat die inspeelt op de vraag in kwantitatieve en kwalitatieve zin voor de middellange (en lange) termijn.
Ellis werkt bij Royal HaskoningDHV als Directeur Business Development & Innovations van de Business Line Buildings sinds juli 2011. Dit advies- en ingenieursbureau opereert wereldwijd met ca. 8000 mensen in 35 landen met diensten op het gebied van ‘Buildings, Water, Maritime, Rivers, Delta’s & Coast, Industry , Energy & Mining, Transport & Assetmanagement, Infrastructure, Aviation and Planning & Strategie’. Hiervoor was ze bij Royal Haskoning Adviesgroephoofd van een groep Corporate Real consultants en was ze zelf consultant op dit gebied. Na haar studie Bouwkunde aan de TU Eindhoven, met een internationale uitstap naar Cornell University, is ze haar loopbaan in 1990 gestart bij EGM Onderzoek. Sinds 2009 is ze tevens docent op de Amsterdam School of Real Estate.
Het werkveld waarin Ellis actief was, betrof de vastgoedadvisering bij publieke en private organisaties vanuit een eindgebruikersperspectief; hoe draagt vastgoed bij aan het verwezenlijken van organisatiedoelstellingen en hun ambities? Ze combineert daarbij het ontwikkelen van toekomstbestendige concepten, financieel/economisch denken in business cases en het managen van stakeholders in de (vastgoed)keten. Daarbij is ze goed thuis op thema’s zoals Het Nieuwe Werken, Transformatie vastgoed, Duurzaamheid en vormen van DBFMO contracten.
