Cost estimators for restoration works

.

In Spain restoration has increased in relative importance within building as a whole as a response to the current property crisis. As a result new economic measures have been taken by the public administrations with the objective of encouraging the sector; official policy has evolved towards models for the regeneration and reuse of the existing housing stock.

This article reviews these measures designed to encourage restoration and the need for them to be accompanied by the efficient forecasting and control of the cost of ali restoration activities. To this end it analyses the methods of estimating restoration costs used by Spanish architects: on the one hand those using the analysis of functional units and on the other those using empirical and statistical mathematical methods

The contrasting of the results obtained reveals that empirical estimation models are more precise. They produce fewer calculation errors than models for analysing functional units, with the main distinguishing element between the two being the inclusion or otherwise of the influence that environmental variables may have on the final cost of the restoration work.
