Approximate Quantities Method of Estimating (Measurement Groups) Advantages and Disadvantages [Building Construction]

The Approximate Quantities method of estimating the cost of a construction project is regarded as the best because it’s more accurate and more reliable than other methods of estimating. This estimate is based on measurement groups where Bill items with the same dimensions (in metres or square metres) are grouped together. This essentially means that …

Unit Method of Estimating – Advantages and Disadvantages [Building Construction]

The unit method of estimating is the simplest and quickest method of estimating the cost of a proposed construction project. In this method, the quantity surveyor counts the number of units which are going to be accommodated in a building, for example the number of occupants or main furniture objects used by an individual. The …
