A quick sensitivity check: moving the lead trade (plumbers, pipefitters and steamfitters) from the median to the 75th percentile wage adds about $770 to the midpoint estimate; the 25th percentile takes off about $510. That is a swing of roughly 3.0% to 4.5% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
