West Cocoon Warehouse Conservation Work (5)

While being removed, every roof tile undergoes a sound check by tapping them in order to judge if they can be reused of not. We reuse original tile as much as possible, but the tiles lacking are replaced by new ones according to a mold made from existing roof tiles. You can see this process on these pictures.

The dumwaiter located approximately at the center of the building was used for cocoons transportaton until the mill stopped operating (package dedicated elevator / Installed in 1971). As this equipment is related to silk-reeling process, we decided to preserve it in-situ on the occasion of current conservation works.

Foundation work for structural reinforcement began.
