PAS 64:2013

Mitigation and recovery of water damaged buildings. Code of practice

Status : Current   Published : July 2013



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.

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

PAS 64 can be used 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.

This PAS was co-sponsored by the National Flood School, Action Dry Emergency
Services Ltd, Cunningham Lindsey, the Environment Agency and Rameses Associates Ltd.
Its development was facilitated by BSI Standards Limited and it was published under
licence from The British Standards Institution. It came into effect on 30 July 2013.
