Duration: 22 weeks
Location: Moorgate, London
 
Description of works:
M&A Roarty Construction, working for Waterland are constructing 4 new
permanent BT chambers, at Moorgate in the City of London.
Over 100m of 48 way ducting was also diverted through tunnels between
the chambers and the old BT exchange.
The temporary working shafts varied in size up to 7m x 6.9m and were up
to 7m deep through some of the heavily service congested ground in
London.
Protection to the existing services was provided both prior to and during
excavation. Existing chambers were decked out above the cables and a
number of other services were supported from beams spanning the shaft
at the surface.
