Hi

We have a eight storey office building that will undergo a larger Core and Shell refurbishment; windows will be changed, the building is u-shaped and the "interior courtyard will be enclosed by glasing - and turned into a wintergarden, inside all HVAC and electrical fittings will be replaced. 1,5 floors will be exluded regarding HVAC and electrical, in these untouched floors the tenants will remain.
One floor will be used as an evacuation plan while the rest of the building is being refurbished.
On the top 2,5 floors the tenant is known and is working with his own tenant fitout. It is not certain whether the fitout will be a part of the construction of the Core and Shell project or if it will be a seperate contract.
Our first thought was that it should be a C&S, but now I'm wondering if NC would be more suitable? Or should it be a EBOM? But in any case how do we handle the floors where nothing is done? Could they be excluded? The developer intends to renovate these areas as well, but they don't know when that is going to happen, could be in two, five or three years, and once renovated they will meet at least the same standards as today.

Would be grateful for all advise on this matter!
Best Regards
