Analysis, design and integration of building elements. External wall systems (walls in contact with atmosphere and ground), window and door systems, floor systems (ground, intermediate and exposed-soffit floors, suspended ceilings, raised floors), vertical circulation systems (ramps and stairs), roof systems (flat and sloping roofs), partition systems (fixed and moveable partitions). Design of building element systems within the frame work of constructional design requirements, criteria and resources. Integration of building element systems in line with the holistic approach.
