Nonresidential Trades Added 12,300 Jobs in September. Housing Shed 7,900.

The Bureau of Labor Statistics released its September employment report on October 2, and one line in it belongs to commercial electrical work. Nonresidential specialty trade contractors, the category that holds commercial electrical, mechanical, and interior contractors, added 12,300 jobs. Total nonfarm payrolls across the entire United States economy grew by 29,000. One slice of nonresidential construction accounted for roughly 42 percent of the month's net hiring.

Construction as a whole added 11,000 jobs, in line with the 10,000-per-month average of the prior twelve months, and the industry is up 109,000 jobs, or 1.3 percent, over the year. Composition is what moved. Nonresidential construction gained 16,100 positions: 12,300 in specialty trades, 2,600 in heavy and civil engineering, and 1,200 in nonresidential building. Residential construction lost 4,900, with residential specialty trades down 7,900 against a 3,000 gain among homebuilders. Over twelve months, nonresidential employment is up 142,000, or 2.9 percent, while residential is down 32,800.

The nonresidential specialty trade payroll series now stands at 2,939,600 workers, up from 2,888,900 in April, a gain of more than 50,000 in five months. Pay moved with it. Average hourly earnings in construction reached $41.69 in September, a 4.2 percent increase from $40.01 a year earlier, against 3 percent growth for the private sector, where average hourly earnings were $37.81. Construction's unemployment rate was 3.5 percent, down from 3.8 percent a year earlier and well below the national 4.2 percent.

Those gains held while the rest of the report weakened. BLS revised July down to a loss of 10,000 jobs and August down to a gain of 133,000, a combined reduction of 60,000 from what had been reported. Associated Builders and Contractors chief economist Anirban Basu attributed the nonresidential concentration to the data center boom and to what he described as insatiable demand for new data centers. Associated General Contractors chief economist Ken Simonson credited data centers, power projects, and advanced manufacturing plants with spurring employment gains in many metros.

On the job, that concentration shows up as duration and scope. Hyperscale shells, substation and switchgear packages, and plant electrical scopes run in phases measured in years rather than the weeks a tenant fit-out takes, and they load crews with medium-voltage terminations, bus duct and switchgear assembly, generator and UPS tie-ins, and the test records a commissioning sequence requires before energization. Electricians who land on that work tend to stay on it. With trade unemployment at 3.5 percent, contractors staffing the next mission-critical job are recruiting from other commercial and industrial projects rather than from a bench, and the 4.2 percent wage gain is the cost of winning those moves. The residential contraction does not relieve it, because house wiring experience does not substitute for medium-voltage work or commissioning documentation.

The broader economy nearly stalled in September. The commercial electrical trades did not.
