This report summarizes in tabular form the results of national studies that were conducted in Belgium, France, Germany, Italy, and the United Kingdom to identify the job skills and knowledge required of persons employed in the fields of rehabilitation and conservation of historic buildings. Presented in chapter 1 is a comparative analysis of the situation existing with respect to the following issues/aspects of the rehabilitation/restoration sector of each of the five countries: legislation and regulation, scale of the market, firms and their workers, and training and qualifications. Chapter 2 consists of 14 tables detailing the skills required in connection with each component of buildings needing rehabilitation/restoration. In the tables, information regarding parts of buildings, defects, contingencies, treatment, techniques, and knowledge is provided for each of the following building components/restoration processes: foundations; walls; partition walls; floors; woodwork; roof coverings; waterproofing and drainage; plasterwork; joinery; glazing; tiling and paving; painting; metalwork; and sanitary installations, heating, and electricity. Discussed in chapter 3 are considerations entailed in building a pool of skilled workers in the restoration and rehabilitation trades and factors conducive to formulating occupational profiles (exchanges and networks, instructor training, and official recognition of qualifications).
