The construction business is cyclical, so it has wide swings in their benefits.One of its main advantages is that it takes relatively little money to make a play, because the client (who commissioned the construction of the project to the construction company) is making partial payments (called certification) during the development of the work. These partial charges reduce capital requirements by the builder when a project.Among its disadvantages, apart from the cyclical nature of business is to have a relatively low profit margins. For example, in the construction of a building housing the profit margin promoter is much greater than that of the constructor.All this makes the good times of the cycle builder construction companies generate a large amount of cash using little capital and in bad times profits fall sharply. This has caused many of these companies enter into business with characteristics very different from the construction business to stabilize the whole enterprise. The strategy is to invest the high liquidity in good times generated by the construction business in these other businesses more stable. Some of these businesses are:Refuse collection, street cleaning, water management, recycling, etc.. These businesses have great benefits stability and higher margins that the business builder.

So a builder has certain knowledge that will make a work a few months before starting it. These works, which the company know you will make in the coming months but have not started yet they constitute the "portfolio of works." This portfolio is specified in time. For example, if a company reports a backlog of works 10 months is saying they have secured work for the next 10 months.
