I am working on a project that involves adding office space to an existing 14' tall single story building. The building is about 60 years old constructed of c.m.u. block walls. The plans indicate demolishing an existing 6" exterior slab on grade (approximately 40' x 12') and replacing it with a new 4" concrete slab as this area will be part of the new interior office space at job completion. The contractor wishes to leave the slab in place and pour over it up to the new interior top of slab elevation. From a structural standpoint, is this a reasonable request as the new slab will be poured over two different substrates (the existing slab and soil)? Is there any surface preparation that should be done to the existing slab?
