Demolition

If a proposed construction project is taking place on a site which already has structures on it then a demolition phase may be required. If the project is taking place on empty land, then no demolition calculations are needed. Alternatively it might be that your projects existing levels have been surveyed post demolition so no calculation is required in that scenario either.

The vast majority of demolition estimating is outside the scope of a volumetric analysis program like Kubla Cubed, however the program can be useful in analysing certain activates where an estimation of volume is required. Even if those volume are not required it is important to complete the demolition phase in order for the existing elevations to be adjusted properly for use in calculating the volumes in subsequent phases. If you imagine a project where there is a 400mm thick concrete foundation that is to be removed during demolition, if you don’t have a phase that reduces that level, subsequent phases that calculate over that area will be inaccurate as they will be calculating from the pre demolition level rather than post.

Demolition must be defined in its own phase. If earthworks elements are place over demolition areas in the same phase they can override the demolition levels effectively making the demolition elements redundant. Instead, demolition elements must be in their own phase so subsequent operations are calculated from the demolition level rather than overriding the level.
