A major objective in the construction industry, just like in other industries is productivity. The achievement of this depends on the input invested and the resultant output. Apart from labor, there are several inputs used by homebuilders to build homes. First, machines are part and parcel of the process. The crushing of stones, mixing of concrete, elevation, and others are made easier when machines are used. Second, electrical energy is also a major input in the industry. The movement of machines, heating, welding, and lighting require electrical energy, and this makes it a key input for homebuilders.
For the machines used as inputs by homebuilders, partial productivity statistics would be the use of less costly machines and the use of fewer but efficient machines. For energy used as an input, partial productivity statistics would be the use of little energy, and the use of cheap energy.
The reduction of the partial productivity of the machines used by homebuilders would be caused by the low quality of the machines or the lack of skill or knowledge for their use. On the other hand, the reduction of partial productivity of the energy would be caused by economies of scale that would make it unaffordable (Rate, 2011).
The improvement of the partial productivity of the machines used would be achieved through the employment of workers with skills and knowledge on how to use them. Conversely, an improvement of the partial productivity of the energy used would be influenced by stressing on efficiency and reduction of energy wastage (Myronenko, 2012).
Partial productivity aside, total productivity is also crucial for homebuilders in the construction industry. It would be calculated by combining the effects of all the inputs or resources used such as energy and machines in the building process and dividing it into the output (Hannula, 2002), which in this case are homes produced.
