ABSTRACT
Unit rates are usually a combination of rates for labour, plant, materials and sub-contractors. Only the direct site cost is included because management will develop a better understanding of the pricing level if on-costs are dealt with separately. There is a more extreme view that rates should ignore some or all of the following:
1 general site plant such as cranes and plant for materials distribution such as tractors and trailers, dumpers and forklift trucks;
2 small plant, tools and safety equipment; 3 general labourers assisting craftsmen, unloading materials, distributing materials and driving
mechanical plant; 4 difficult working conditions such as access, restricted space and exposure to the weather.
