Road works, street works, utilities, etc should all be coordinated so that you don't end up with traffic chaos/gridlock. it'll be a mixture of Southwark council highways department, Transport for London (if it includes red routes, or bus routes), and possibly the GLA too.
The council should have planned which streets, and footways they are going to resurface, and when, in advance to avoid clashing with planned utilities works (like the Thames water, replacing Victorian water mains).
There will (should) be a NRSWA (New Roads and Street Works Act) department/section in Southwark Council
as to the timings, works are generally carried out at the least busy / most convenient time, so not during rush hour on a weekday, and when it's quite, so evenings and weekends.
Hope that helps
