ABSTRACT
Both mechanical services subcontractors did not explicitly state that they categorized their suppliers beyond the above classification and they did not have a rational method for purchasing by volume across their firms. In this channel, the industrial building has highly complex and specialized products, somewhat similar to the specialized products identified in the concrete industrial market. They are a subsidiary of a formwork firm in Singapore who in turn are owned by a multinational firm with numerous divisions in various construction commodity markets. The first product is the formwork for the concrete wall for the core of the high-rise building and the second is the protective screen system around the perimeter wall of the building. The markets which the concrete subcontractors operate in are residential, commercial and industrial.
