The key European participant was Trischler and Partner. The work was done in close cooperation with the Chornobyl Shelter operations and Ukraine institutes. The Shelter Implementation Plan will support the development of G-7 pledges to the project. Those financial pledges are an expected outcome of the G-7 Summit scheduled for June 20 and 21 in Denver, Colorado.

The next step in the International Shelter Project is to develop bid packages for urgent early-start projects. Those bid packages will be tendered as soon as possible to keep the shelter project on schedule. U.S. participants in this effort will include Parsons Power Group and Science Applications International Corporation. The key European participant will be Trischler and Partner. The G-7 has selected the European Bank for Reconstruction and Development (EBRD) to manage the finances for the project and hire an organization to manage the work in the field. Over the next several months, the International Shelter Project team will work with EBRD and the Chornobyl Shelter operations organization to develop the early-start project packages for tendering by fall 1997.
