A natural way to construct such processes is via Dirichlet forms restricted to the function space whose members take constant values on these collapsing parts. They include as a special case Brownian motion with darning, which has been studied in details in \\cite{Chen, CF, CFR}. When the initial processes have discontinuous sample paths, the processes constructed in this paper are the genuine extensions of those studied in Chen and Fukushima \\cite{CF}.
