Much has been achieved, but more work is needed to address many of the distinct challenges to conserving the heritage of the 20^(th) century. In 2011, the Getty Conservation Institute (GCI) launched its Conserving Modern Architecture Initiative (CMAI), which seeks to respond to the outstanding current challenges and contribute to advancing practice in this emerging area of conservation. It began with a survey of the field to identify where existing efforts could be best supported and enhanced, or where knowledge gaps could be potentially filled. In response the GCI built a comprehensive program to meet these identified needs and five years later, a number of activities and projects are underway. These include a series of publications, a training program, historical and technical research and two field projects at Louis Kahn’s Salk Biological Institute (1965) and the house of Ray and Charles Eames (1949), both in California. This paper outlines current GCI efforts, reports on initial outcomes and describes forthcoming activities.展开更多
