Construction Methodology • Maximises use of ‘abnormal’ possessions to minimise ‘out of

hours’ working i.e. Week 9 replacement coper works is equivalent of 6 weeks of weekday nights

• Co-ordinate as many of the ‘noisy’ & ‘dusty’ activities i.e. removal of structures into the three ‘abnormal’ possessions

• Use of acoustic screens to contain plant noise• Use of mains power to supply site accommodation – saves need

for 24/7 generator• Wet cutting of materials to suppress dust• Full encapsulation of Public Footbridge so works can be

completed in daytime hours
