An assembly hall on a board that had been added to for twenty years, and five weeks of school holiday to put it right.
We priced the job off the load schedule rather than off a materials list, which found two circuits that had been sharing a breaker since the hall was extended. New board, new cable, new fittings, and a set of as built drawings the school actually has a copy of.
Finished with a week of the holiday still to spare.
