Nonresidential Backlog Rebounds as Data Center Demand Tightens Labor Market
Associated Builders and Contractors (ABC) reported that its nonresidential backlog measure increased by half a month in August, rising from 8.0 months to 8.5 months and matching the level recorded one year earlier. Contractors with data center work reported a stronger 9.9 months of backlog, compared to 8.3 months for firms without data center projects.
Roughly one in six ABC members reported having data center work, the highest share recorded in the survey, underscoring the sector’s growing role in supporting nonresidential construction activity.
ABC’s staffing confidence index declined from 62.3 in July to 59.5 in August, indicating weaker hiring expectations. However, the August reading remained above 50, the threshold signaling expected staffing growth over the next six months, even as 12.3% of contractors planned to reduce staffing.
For AEC firms, the higher backlog among contractors with data center work points to continued near-term demand, but labor constraints could make projects more expensive and difficult to staff. Among firms experiencing workforce effects from data center activity, 58% said it had intensified competition for skilled labor, while 49% said it had contributed to upward pressure on wages.
Fed Rate Increase Adds Financing Pressure to Construction Projects
The Federal Reserve raised its interest-rate range by 25 basis points to 3.75%–4.00%, marking its first increase since 2023 as inflation remained above the central bank’s 2% target.
The rate increase comes as the industry is already dealing with higher construction input prices. Elevated material and labor costs are pressuring project economics, leaving owners and developers with less room to absorb higher financing costs.
Industry economists said the rate increase will immediately raise the cost of floating-rate construction loans and prime-linked short-term credit. The added expense could push marginal commercial projects below their profitability targets, increasing the risk of delayed payments, project holds, or abandonment on active work.
For AEC firms, the rate increase may create greater near-term risk in housing and private commercial development, which are more sensitive to borrowing costs. Firms may need to evaluate owners’ financing capacity more closely when pursuing new work and monitor receivables on debt-dependent projects.
