Introduction

Water damage to a building can lead to increased public health risk and a reduction in its value and usefulness, which can increase over time if not dealt with in a managed and co-ordinated way.

Mitigating water damage by effective drying solutions is an important part of the total recovery process. Cleaning protocols and assessment of indoor air quality might also be required depending on the profile of the water damage incident.

This PAS provides recommendations and guidance for the restoration of a water damaged building from the initial incident to the point at which repair and reinstatement commence.

1 Scope

This PAS gives recommendations for the mitigation and recovery of buildings damaged by water. It is applicable to all forms of water damage to buildings.

It covers the mitigation and recovery process including:

a)	initial inspection of a water damaged building;
b)	setting drying and cleaning goals (including air quality goals);
c)	selecting the drying and cleaning techniques and equipment to be used;
d)	monitoring the drying and cleaning progress;
c)	verifying drying and cleaning goals have been met;
f)	documentation for provision to the customer.

It also provides further guidance to support the application of this PAS including descriptions of techniques and equipment in current use, example forms and example calculations.

This PAS does not cover building repair and reinstatement. However, it is recognized that the restorative drying process is a primary stage of the overall repair and reinstatement process.

It does not cover the restoration of contents other than the implications for drying or restoring the building.

It is for use by restorers and may be of interest to building owners and occupiers, insurance companies and their representatives and those involved in the subsequent repair and reinstatement of a building.
