Concrete curb with a steel reinforcement for concrete

Design a concrete curb with a steel reinforcement for concrete aimed to incorporate roof beams. The work consists of designing the layers with all necessary renderings: the concrete curb with details of the incorporated steel structure which shall be able to reinforce the concrete and to tie together all roof beams. The beams shall contain holes (to be designed) where steel from the frames goes through in a harmonized way so to create a solid and uniform structure. The final result would appear as a concrete ring on top of the walls of the building's perimeter which incorporates the beams in a way that the beams are fully incorporated inside the concrete, and a layer of the same design should clearly show the steel structure, using the mining amount of metal. The concrete curb length, as well as the metal frame inside, is equal the all perimeter of the building's wall, its width is the same as the bricks which make the wall, i.e. 25 cm, and its height is 38 cm.
