How to choose right construction equipment for your project?Most of the construction projects involve laborious work which is to be handled by men and the equipment designed for doing the work undersigned. It is difficult for workers to accomplish all things in a project and so there comes the need for machines particularly the construction equipment (machinery) that is widely used nowadays almost everywhere in the world. For speedy and economic construction of a project, proper choice of equipment is of preliminary importance for civil engineers. The versatile range of equipment available commercially involves the decision of people. There are few basic things that are considered in selection of suitable equipment. They are as follows:
Use of Available Construction Equipment:Where the full utilization of new equipment for its entire working life is not foreseen, or its utilization on further projects is uncertain, it may be desirable to use existing old equipment even if its operation is somewhat more expensive. The depreciation cost of the new machine is likely to be high, and this would raise the owning cost of the equipment and thus the unit cost of work.
Suitability for Job Conditions:The equipment chosen should suit the conditions of the job, soil, valley, working conditions and climate of the region.
Uniformity in Type:A minimum number of types should be acquired so that there is uniformity in the type of equipment on a job. A common type of engine should be selected for the different types machines such as excavators, dump trucks, tractors and scrapers that are on the project.
Size of Construction Equipment:Larger equipment gives higher output on full load, but its cost of production on part load is usually greater than that of smaller units working on full load. Larger equipment needs correspondingly larger size of matching units, and shutting down of one primary unit may render several other large units idle. Transportation to works is generally difficult and costly. Servicing, maintenance and repair facilities have to be greater for larger units. However, larger machines are usually more sturdy and suitable for tough working conditions. It is desirable to have equipment of same size on the project. With standbys, the cost of larger size standby equipment is more than that of smaller size.
