By 1983, some 200 of such Kingdom Halls had been erected in the United States and Canada. To accomplish the work, brothers began forming regional building committees. This method worked so well that in 1986, the Governing Body formalized the arrangement, and by 1987, there were 60 Regional Building Committees (RBCs) in the United States.a By 1992, RBCs had also been appointed in Argentina, Australia, France, Germany, Japan, Mexico, South Africa, and Spain. To be sure, the hardworking brothers who build Kingdom Halls and Assembly Halls deserve our support, for the work they are doing is part of sacred service.
