Wages behind the Delaware number

Statewide wages come from BLS's state-level estimates, which blend big cities with small towns and rural areas. 3 trades drive the labor line for this job, and the weighted ratio against the national wage level is 0.99 for Delaware.

For plumbers, pipefitters and steamfitters (47-2152, weighted 40%) the local median is $31.11 an hour, which is in line with the national $30.67. The middle half of them earn between $24.93 and $37.42 an hour. BLS counts 1,590 of them working in the state, 32.8 for every 10,000 jobs (US: 30.0), so the local bench is about average.

Construction laborers (47-2061), 40% of the weighting: a median of $21.90 an hour, 3% below the US median of $22.66. The middle half of them earn between $17.93 and $27.07 an hour. About 3,240 work in the state. That is 66.8 per 10,000 jobs, compared with 70.5 nationally, so the supply of crews looks typical.

For operating engineers and other construction equipment operators (47-2073, weighted 20%) the local median is $27.89 an hour, which is 3% below the national $28.78. The middle half of them earn between $22.36 and $31.80 an hour. BLS counts 1,230 of them working in the state, 25.4 for every 10,000 jobs (US: 30.7), so the local bench is thinner than average.

A crew paid at the 75th percentile for plumbers, pipefitters and steamfitters ($37.42 an hour) would add about $300 to the statewide midpoint; one at the 25th percentile ($24.93) would take off about $290. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.

Dover has 9 comfortable months (March through November), with about 48 inches of precipitation a year.

We do not adjust prices by month, because we have no reliable published data on seasonal pricing. Timing is still worth raising when you collect bids.
