## 4 Common Estimating Methods Used by Quantity Surveyors and Construction Cost Engineers

Preliminary estimates also known as conceptual estimates are done in the design and planning stage of a construction project. There are several methods of estimating, some of which are obsolete and some which are highly recommended and used by Quantity Surveyors today. The following is a list of estimates that a Quantity Surveyor can …

## 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 …

## Elemental Method of Estimating – Advantages and Disadvantages [Building Construction]

When compared to the Unit and Superficial Area method, the Elemental Estimate or elemental method of estimating is a more detailed method of calculating the cost of a construction project. This estimate is easily understood by the client or any party involved in the design consultation because it shows separate elements of the building …

## Square Metre Method of Estimating – Advantages and Disadvantages [Building Construction]

The superficial floor area also known as the square metre method of estimating is one of the quickest methods of calculating the cost of a building/construction project. It is the first estimate that will be prepared by a Quantity Surveyor when initial sketch drawings are produced by the architect. In this early planning and design …

## 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 …
