Overamstelhotel Leonardo Hotels te Amsterdam

The Precast Structure of the Overamstelhotel in Amsterdam is designed, engineered and built by CD20-Building Systems commisioned by Slavenburg Bouw Adriaan Van Erk. The 19 storey 490-room hotel with suites parking, ballroom, conference, wellness, restaurant and skybar will be serviced by Leonardo Hotels. The fast to built precast concrete structure exists of monolith prestressed floorslabs on precast walls and loadbearing sandwich-facades with architectural concrete and precast brickwork, mounted completely with windows and glazing, without the need of any scaffolding.

Debugging the design with changes from different disciplines, architectural, structural, mechanical, electrical, fire-safety, elevators and specially clash-checking sewer, HVAC and electrical vaults with structural joints have been challanges during design. All the electrical, fire-safety an Plumbing- and sewer systems are designed in BIM and integrated in the precast prestressed floorslabs. Also modelling the aprox. 280.000 pieces of bricks, integrated in the precast sandwichfacades have been a real design-challenge in the structural model.

Intensive collaboration between the project-partners, main contractor Slavenburg Adriaan van Erk, architectArchitect Marc Verlaan m@architect , structural contractor CD20-Building Systems, Royal Haskoning DHV engineering, Kemp, SDR, Hiensch Engineering and Bas Hennes Design. Using integrated design with BIM models in all disciplines, from the first intitial preliminiary designs till production and installation, the proces is digitally monitored and optimized. All the architectural, structural, electrical, HVAC, plumbing and sewer- systems have been designed in aspectmodels which are integrated in a central model, scrummed and checked on clashes in weekly designmeetings with the whole team of designers and subcontractors.
