A construction foreman is responsible for keeping track of all the materials found on a construction site. They also need to know the weights of materials to ensure they are ordering the correct amount needed for the job. Some of the materials used on a construction site are concrete, timber, stone, steel bars and plywood. Typically a Purchasing Manager negotiates prices with different
. distributors to get the best price. This allows the construction company to increase their profit margins while still providing the customer with a good final product. You can find more information here: http://www.mcvicker.com/resguide/page011.htm
