If you are planning more than one job in Alaska
The table prices neighboring jobs at their usual sizes using statewide Alaska wages and prices. Against national midpoints, concrete driveway comes out highest (+32%) and gravel driveway lowest (+16%), because each job leans on different trades.
| Project | Size | Range | vs. US |
|---|---|---|---|
| Concrete driveway | 600 sq ft | $4,700 – $12,200 | +32% |
| Concrete patio | 300 sq ft | $1,500 – $5,100 | +25% |

| Gravel driveway | 1,000 sq ft | $2,900 – $11,800 | +16% |
When Alaska weather lets you pour
Season matters for concrete slab. For each Alaska metro below we took NOAA's 1991-2020 monthly normals from the nearest suitable station and counted comfortable months for pouring concrete.
Anchorage has 3 comfortable months (June through August), with about 23 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.
| Metro | Jan avg low °F | Jul avg high °F | Precip (in/yr) | Comfortable months |
|---|---|---|---|---|
| Anchorage | 6 | 67 | 23 | 3: June through August |
Extras that change the Alaska total
Extras are quoted nationally and then scaled to Alaska by the average of the local wage index (1.44) and goods index (1.06), a factor of 1.25. Tick any of them in the estimator above to add them to your total. Treat these as planning figures: an add-on touches different trades than the main job, so the scaling is an approximation.
| Add-on | Local range |
|---|---|
| Add rebar reinforcement | $500 – $1,500 |
| Remove old concrete first | $1,000 – $3,000 |
What cement masons and concrete finishers and the other trades earn in Alaska
Statewide wages come from BLS's state-level estimates, which blend big cities with small towns and rural areas. 4 trades drive the labor line for this job, and the weighted ratio against the national wage level is 1.44 for Alaska.
For cement masons and concrete finishers (47-2051, weighted 50%) the local median is $44.69 an hour, which is 63% above the national $27.41. The middle half of them earn between $44.33 and $54.34 an hour. BLS counts 240 of them working in the state, 7.4 for every 10,000 jobs (US: 13.3), so the local bench is thinner than average.
Construction laborers (47-2061), 30% of the weighting: a median of $27.91 an hour, 23% above the US median of $22.66. The middle half of them earn between $22.30 and $33.63 an hour. About 3,690 work in the state. That is 113.3 per 10,000 jobs, compared with 70.5 nationally, which suggests plenty of local crews to bid.
For operating engineers and other construction equipment operators (47-2073, weighted 10%) the local median is $37.41 an hour, which is 30% above the national $28.78. The middle half of them earn between $32.13 and $48.03 an hour. BLS counts 3,050 of them working in the state, 93.7 for every 10,000 jobs (US: 30.7), so the local bench is deeper than average.
For carpenters (47-2031, weighted 10%) the local median is $35.51 an hour, which is 22% above the national $29.12. The middle half of them earn between $28.74 and $45.26 an hour. BLS counts 2,560 of them working in the state, 78.6 for every 10,000 jobs (US: 43.1), so the local bench is deeper than average.
A crew paid at the 75th percentile for cement masons and concrete finishers ($54.34 an hour) would add about $280 to the statewide midpoint; one at the 25th percentile ($44.33) would take off about $10. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 325,570 jobs across Alaska (May 2025), which is 0.2% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Cement masons and concrete finishers (47-2051) | 50% | $44.33 | $44.69 | $54.34 | $27.41 | 1.63 | state |
| Construction laborers (47-2061) | 30% | $22.30 | $27.91 | $33.63 | $22.66 | 1.23 | state |

Alaska against its neighbors
Alaska ranks 2 of 51 (the 50 states plus DC) for concrete slab, where 1 is the most expensive. The costliest is Hawaii at $5,150 and the cheapest Arkansas at $3,350, both for 400 sq ft at the midpoint. Alaska sits at $4,650. The five states closest by workforce center are listed below.
| State | Distance | Range | Midpoint | vs. here |
|---|---|---|---|---|
| Washington | 1500 miles away | $2,850 – $5,950 | $4,400 | −5% |
| Oregon | 1600 miles away | $2,700 – $5,650 | $4,200 | −10% |
| Idaho | 1870 miles away | $2,400 – $5,050 | $3,700 | −20% |
| Montana | 1880 miles away | $2,450 – $5,200 | $3,850 | −18% |

Concrete slab: what moves the price in Alaska
Thickness and mix
A 4-inch slab uses about 1.23 cubic yards of concrete per 100 sq ft; a 6-inch slab uses about 1.85. Stepping up from a 3,000 PSI to a 4,000-4,500 PSI mix adds $10-$40 per cubic yard (Estimators.us).
Base and reinforcement
A compacted gravel base, vapor barrier, and wire mesh or rebar are priced separately by some contractors and bundled by others. Ask which one your quote does.
Truck and pump access
If the mixer truck can't back up to the forms, someone has to wheelbarrow it in or hire a pump. Pump or line-pump hire is typically billed per day.
Small-job minimums
Many crews have a minimum charge, so a 10x10 pad can cost more per square foot than a 20x20 slab.
Finish
A broom finish is the baseline. Stamped, stained, or exposed-aggregate finishes are priced as add-ons on top of the slab.
Alaska metro-by-metro prices
Alaska has one metro in our dataset, Anchorage, so the statewide and metro figures are close. The state figure uses BLS statewide wages, which include rural areas. Each row prices the default size with that metro's own BLS wages and BEA price levels, so the gap between rows is real local variation rather than a flat markup.
| Metro | Range (400 sq ft) | Midpoint | vs. state |
|---|---|---|---|
| Anchorage, AK | $3,050 – $6,250 | $4,650 | level |
