What local crews earn in Olympia

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 Olympia the blend is 1.30.

Plumbers, pipefitters and steamfitters (47-2152), 40% of the weighting: a median of $38.48 an hour, 25% above the US median of $30.67. The middle half of them earn between $28.18 and $48.74 an hour. About 310 work in the metro. That is 23.8 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 $25.52 an hour, which is 13% above the national $22.66. The middle half of them earn between $21.90 and $33.85 an hour. BLS counts 730 of them working in the area, 56.0 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 $49.55 an hour, 72% above the US median of $28.78. The middle half of them earn between $33.47 and $54.71 an hour. About 260 work in the metro. That is 20.0 per 10,000 jobs, compared with 30.7 nationally, so expect fewer local crews to bid.

A quick sensitivity check: moving the lead trade (plumbers, pipefitters and steamfitters) from the median to the 75th percentile wage adds about $490 to the midpoint estimate; the 25th percentile takes off about $490. That is a swing of roughly 5.9% to 5.9% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.

Olympia weather and the sprinkler system calendar

Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Olympia Ap (5 miles from the city center). 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 Olympia are March through January: 11 of 12. Outside them, February has an average overnight low at or below freezing (32°F).

In February the average low is at or below freezing, which means frozen ground and slower digging, compaction and sod or stone placement. NOAA counts about 77 days a year with a low at or below 32°F at this station.

Olympia gets about 51 inches of precipitation in a normal year, including roughly 4 inches of snow. The wettest months are January, November and December (8.2 inches in November). Inside the workable window, July and August are the driest, at 0.5 and 1.0 inches. The station averages about 7 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.
