Walls are precast concrete panels and dense blockwork; locally that also means often with surface conduit — the reality on the streets around Shadwell Basin, so the fixing that matters in Shadwell is chosen on site — the usual failure here is drilling blind into a panel with reinforcement or a buried cable behind it on these streets — measured on the walk in from Shadwell (DLR, Overground) rather than assumed from a map.
Two streets can behave very differently in Shadwell: basin flats, Watney Market and the streets between Whitechapel and the river. The quote reflects the street the job is actually on. Shadwell sits inside the Congestion Charge zone as well as ULEZ, so both are itemised on the quote rather than absorbed into an hourly rate.
On access, the Highway red route, cycle-superhighway kerb build-outs and estate lift booking — one reason one technician with a van-mounted dip tank; two where a barbecue has to be carried through a flat to reach a terrace. Fitters travelling in use Shadwell (DLR, Overground).
