Building material is material used for construction. Many naturally occurring substances, such as clay, rocks, sand and wood, even twigs and leaves, have been used to construct buildings. Apart from naturally occurring materials, many man-made products are in use, some more and some less synthetic.Construction equipments are one of the very important resources of modern-day construction, especially in infrastructure projects. Such projects utilize equipments for most of the works including earthmoving operations, aggregate production, concrete production and its placement, and so on. In fact, one cannot think of any major construction activity without the involvement of construction equipment. There are different types of construction equipments suitable for different activities in a construction project. The choice of construction equipment defines the construction method, which in a way leads to the determination of time and cost for the project. In order to select the right equipment to perform a specific task at the least cost, it is essential to know the features of a construction equipment including its rate of production and the associated cost to operate the equipment.
