Who does the work: Dover trade wages

The labor line is built from BLS wage data, one trade at a time. This job draws on 3 trades. We compare each trade's local median with the US median, weight the ratios by how much of the job each trade does, and apply the blend to the national labor cost. For Dover the blend is 0.92.

Plumbers, pipefitters and steamfitters (47-2152), 40% of the weighting: a median of $28.08 an hour, 8% below the US median of $30.67. The middle half of them earn between $24.22 and $36.70 an hour. About 90 work in the metro. That is 13.2 per 10,000 jobs, compared with 30.0 nationally, so expect fewer local crews to bid.

For construction laborers (47-2061, weighted 40%) the local median is $22.02 an hour, which is in line with the national $22.66. The middle half of them earn between $18.50 and $24.63 an hour. BLS counts 400 of them working in the area, 58.8 for every 10,000 jobs (US: 70.5), so the local bench is thinner than average.

Operating engineers and other construction equipment operators (47-2073), 20% of the weighting: a median of $23.49 an hour, 18% below the US median of $28.78. The middle half of them earn between $21.38 and $28.71 an hour. About 190 work in the metro. That is 27.9 per 10,000 jobs, compared with 30.7 nationally, so the supply of crews looks typical.

A quick sensitivity check: moving the lead trade (plumbers, pipefitters and steamfitters) from the median to the 75th percentile wage adds about $410 to the midpoint estimate; the 25th percentile takes off about $180. That is a swing of roughly 2.8% to 6.2% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.

Dover has 68,080 jobs in total (BLS, May 2025), ranking 265th by size among the 300 metros on this site.

Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Dover (in the city). They are 30-year averages, so any one year can run hotter, colder or wetter.

For digging, grading and setting material in the ground, the comfortable months in Dover are March through November: 9 of 12. Outside them, January, February and December have an average overnight low at or below freezing (32°F).

In January, February and December the average low is at or below freezing, which means frozen ground and slower digging, compaction and sod or stone placement. NOAA counts about 79 days a year with a low at or below 32°F at this station.

Dover gets about 48 inches of precipitation in a normal year, including roughly 13 inches of snow. The wettest months are June, August and September (4.9 inches in August). Inside the workable window, April and November are the driest, at 3.7 and 3.4 inches. The station averages about 25 days a year at 90°F or above.

We do not adjust the estimate by month, because we have no reliable published data on seasonal pricing. It is still worth asking contractors whether an off-peak start date changes their bid.
