Hello,
I can model a commerical project for you very easily in metric in Revit 2015.
I have done high rise commercial office towers, small commercial office tenancies, banks, hospitals, schools, houses and many more in Revit over the past 10 years.
I am a Senior RIBA Architect and Global BIM Manager.
My estimate is subject to the complexity of the model and level of detail content provided by yourself.
Thanks
Morrow
