Vault Conversion

Civil Engineering Work 19^th February - 5^th April 2002

Vault HVAC room

19th - 27th February Walls are demolished, hvac equipment removed and concrete supports demolished. Note the interesting use of tape shelving units in the 3rd picture!
13th - 22nd March The duct feeding the hvac unit with fresh air is demolished (this will be routed under the false floor in future) and the walls of the new room are built up.

MG Room HVAC room

20th February - 1st March The supporting walls and the dalle holorib are demolished. Initially, this was done by ramming the walls and watching the dalle fall! Safer methods were introduced later... The "holorib" sheeting which supported the concrete sheeting can be seen in the 4th picture. The final picture shows a view through into the former CS storage area; a new wall will be built here in line with the rest of the back wall.
6th - 19th March Building up the walls between the vault and the storage areas.

UPS battery room

20th February - 22nd March The door into the vault is blocked off and the cloison covering the brick wall is replaced—evidently this wall was built from the inside of the battery area.

Turning the old MG room into new storage space

26th February The left hand picture shows the inside wall of the MG room with the grilles for air to come from the plenum. This wall is knocked down (pictures 2 & 3) as the plenum is no longer needed. The door into the hvac plant room (picture 2) will be bricked up. Picture 4 shows a new wall being built up here (and the left edge shows some of the new cloisons.) The last two pictures show work to break openings into the Saleve side corridor; the final picture shows clearly the blocking up of the former doors into the MG room.

Small items

Filling in the grooves from the old tape rack rails.
Cutting a hole so the smoke extraction duct can connect to the chimney.
