WORK ON Crossrail will cause more disruption than other building sites in London, because work will be allowed to carry on for an extra two hours each day, local authorities warned this week.
Enabling legislation for the project allows for Crossrail sites to stay open between 7am and 7pm, while most other London sites are restricted to work between 8am and 6pm.
London boroughs along the route are to push for a cut in proposed working hours in evidence to be submitted shortly to the transport select committee.
The committee is to examine the Crossrail bill in the autumn.
Corporation of London highways and transportation director Joe Weiss told NCE: 'Crossrail should be constructed to the standard hours that we allow for all development in the city.
As soon as you give way on this we will have every developer banging on our door.' The Corporation is also in talks with the Crossrail promoter company to change the location of tunnels routed directly under the Barbican housing estate after residents claimed tunnelling could cause subsidence and excessive noise.
Residents were concerned at plans to build a 180m crossover cavern using the New Austrian Tunnelling Method (NATM).
Construction of the cavern would also involve running a 24 hour concrete batching plant on Aldersgate Street. And this is the point where spoil will be removed.
Weiss is due to meet Crossrail offi ials in the next week to discuss an alternative site for the cavern closer to Moorgate Underground station.
A Crossrail spokesman said that working hours and construction near the Barbican were both up for discussion and nothing was set in stone.
'We have a proposal which will then be modifi d to suit each local authority, ' said a spokesman. 'I'm sure there will be deals made provided it doesn't make the project more expensive.'
