Hi,
I’m working on a C&S project and have a problem with defining the roof area of the project. The project has parking underground and three floors of retail spaces. Above one part of the building there will be unenclosed parking spaces (2 floors in total) with roof parking. Does the roof parking of the parking tower need comply with the SRI requirements or can this area be excluded from the roof area?

The roof parking covers the unenclosed parking floors and could be excluded from the roof area according to “‘Roofs’, or portions of roofs, covering unenclosed areas (e.g. roofs over porches and open covered parking structures) are not included in the areas used to evaluate compliance with SSc7.2, though they may be applicable to SSc7.1.“ However the roof parking is also the roof of the retail spaces under the unenclosed parking floors and should be included in the roof area according to “Roof area is the area of the uppermost surface of the building which covers enclosed Gross Floor Area.”

Any ideas?
Thanks.
