Section 3: instructions

3.3 Element unit quantities

Express the cost of the element in units that relate solely to the quantity of the element itself – element unit quantities (EUQ). Element unit quantities are specified in the element definitions.

3.3.1 Area for element unit quantities

Measure floor areas for element unit quantities as for gross internal floor area (GIFA), i.e. to the internal face of the enclosing wall to the area treated or serviced.

3.3.2 Cubes for element unit quantities, etc.

Cubes for air conditioning, etc. (treated volume), shall be the floor area, measured to the internal face of the enclosing walls of the treated space, multiplied by the height from the floor finish to the underside of the ceiling finish (abbreviated to Tm³).

3.4 Specification and design criteria

For eaxh element give specification and design criteria relating to requirements, purpose and function of the element.

The specification notes are considered to reflect designers’ solutions to the conditions expressed by the design criteria and should indicate the quality of building achieved.

Specification notes should adequately describe the form of construction and quality of material sufficiently to explain the costs in the analysis.

The element definitions (Section 5) provide a checklist of the items that should be included with each element.

Include costs of any significant items.

Any work included that is not covered by the elemental definition should be noted.

3.5 Credits

Details of the client, consultants and contractor. Obtain permission before providing names.

3.6 Drawings

Sufficient drawings should accompany an analysis to aid understanding of the costs. Normally, elevations and a typical floor plan should suffice.
