Building pollutants and demolition

Building pollutants could entail economic and health damages

The quality of the building substance is decisive for

• the unrestricted usability, without employees becoming ill or stored goods becoming damaged, as well as
• the economic conversion and dismantling, without having to use expensive remedial methods and make costly disposal routes.

A building pollutant investigation serves the assessment of the contamination of building pollutants of construction objects. The activities focus on identifying and evaluating relevant information about building data (e.g. year of construction and use history of the buildings), suspected points of contamination and the associated contamination in building materials.
Normally the initial building pollutants investigation (Phase I) is based on an examination of documents and a site inspection with

• Recording and documentation of possible polluted building components,
• Photo documentation and
• Preparation of a findings register.

The building pollutants investigation (Phase II) follows the initial building pollutants investigation, whereby the detection of building pollutants occurs for the determined suspect materials by means of sampling and analysis. The interpretation of the results reveals using relevant threshold values, whether use restrictions or special demolition- and disposal expenditures could arise as cost driver.
