Volatile Steel and Concrete Input-Cost Pass-Through Risks

Steel prices fluctuated 25–40% annually during 2023–2025, while cement and ready-mix concrete rose 15–20%, squeezing project budgets and elevating risk of scope reduction. Fixed-price contracts thus expose firms to margin erosion and cause public-sector owners to delay bids, suppressing near-term billable hours in the U.S. engineering services market. Cost-plus agreements mitigate exposure yet face procurement hurdles. Escalation clauses and material indexes are gaining traction, but uncertainty still dampens CAPEX confidence, trimming the CAGR projection.

Lengthy NEPA Environmental Reviews Delaying Starts

Major transmission lines and pipeline corridors now average 18–36 months in NEPA review, tying up engineering teams without revenue recognition and extending payback horizons for owners. Although new guidance on environmental justice adds service scope, the delays defer cash inflows, hitting smaller consultancies hardest. Lenders increasingly require evidence of expedited permitting strategies, compelling owners to engage specialized environmental consultants earlier, slightly offsetting the negative CAGR drag on the broader U.S. engineering services market.
