Technical Booklet C Site Preparation and Resistance to Contaminants and Moisture·Page 19·3.14, 3.15
Identifying suspected contaminants during construction
Building control procedures require immediate notification to the district council and Northern Ireland Environment Agency if signs of possible contaminants are suspected during a project, and expert remedial advice should be sought if contamination is confirmed.
There may be some occasions when a site containing contaminants has not been identified at planning stage, and the presence of contaminants is suspected later. Some signs indicating the possible presence of contaminants are given in Table 3.3.
If signs of possible contaminants are identified the district council and the Northern Ireland Environment Agency should be informed at once. If the presence of contaminants is confirmed some form of remediation may be required and where necessary expert advice should be sought to provide a remedial solution.
