 where normally a real estate developer will put out a request for proposal for a building, and then someone will answer that request for proposal, typically an architecture firm or engineering firm or both. And they will designate a builder or a general contractor, and the general contractor will then buy concrete from a concrete company. And in order to make the concrete, that concrete company buys cement from a cement company. And usually the cement company and concrete company are the same parent company. So the only companies that ever buy cement are concrete companies, which are typically owned by cement companies.
