Revit 2018 - Architectural Modelling. Increase height of 3 buildings

Dear All,

We have a requirement to increase the 3 buildings shown in the attached images to 20 Storeys, currently, 2 buildings are 11 storeys and other 10, these are inclusive of Ground Floors.

Please duplicate the residential/apartment levels and use these to make up the additional floors. There is a mix of 3D and 2D furniture detailing within the apartments which we want to copy up throughout the new floors along with room volumes.

The existing models which will be sent to the successful applicant are in Revit 2018 so this is the format and year we wish to keep them in.

We require these works to be completed by Friday 21st September.

Thank you
Lee
