SOLUTION: The existing clean room 1 is partitioned by temporary walls 10 to form reconstruction sections 2 in the existing clean room 1. A tunnel booth 20 is formed in the reconstruction section 2 to gain an access to the partitioned sections of the existing clean room 1. A working truck 30 capable of running in the reconstruction section 2 is so disposed as to straddle the tunnel booth 20. The construction of the reconstruction section 2 is performed from the working truck 30 while operating the existing clean room 1. COPYRIGHT: (C)2009,JPO&INPIT
