RFID APPLICATION in CONSTRUCTION l The Need: for tracing and identifying construction equipment on construction sites. l With RFID technology, no line of sight or direct contact is required between the reader and the tag. l Since RFID does not rely on optics, it is ideal for dirty, oily, wet or harsh environments. l RFID is an automatic identification technology, similar to bar code technology. l The Technology: consists of two major components (reader and the tag) which work together to provide the user a non- contact solution to identify people, assets, and locations. l Since RFID tags are read by low voltage radio waves instead of light waves (as with bar codes) they will communicate through non-metallic materials such as paint, plastic, grease and dirt.

EQUIPMENT OWNING and OPERATING COSTS l The costs associated with construction equipment is of two types; fixed costs and variable costs. l Fixed costs; depreciation, insurance and interest. These accrue and are directly related to the time equipment is owned. l Operation costs; operation of the machine, tires, gas, oil and operator’s wages. Other costs occur as a result of the need to set aside moneys for both routine and unscheduled maintenance. Thus operating costs are variable costs. l The total of owning and operating costs for items of equipment such as tractors, shovels, loaders and backhoes is expressed on an hourly basis. These two costs accrue in different ways l Ownership costs are arrived by using estimated total service life in hours to the total of those costs. Idle hours is part of general operating O/H l Operating costs are variable, being a function of a number of operating hours l The hourly charge for a piece of equipment is made up of four elements. Estimates of hourly O/H costs are added to the ownership and operating costs.
