Infrastructure Winners, Tariff Wildcards, and the Margin Squeeze Gripping the US Construction Sector

The construction sector enters the second quarter of 2026 deeply divided — infrastructure and data centre specialists are thriving while traditional contractors battle a historic cost squeeze. Here is what civil and construction engineering professionals need to watch this week.

EVENTS SPOTLIGHT


The construction industry has rarely presented such a stark contrast between winners and losers.

On one side, a select group of infrastructure-focused engineering firms are posting record backlogs and double-digit earnings growth.

On the other, traditional contractors face what analysts are calling the sector’s third major margin squeeze in a decade — a brutal combination of tariff-driven material costs, persistent labour shortages, and bid prices that are simply failing to keep pace.

For investors, engineers, and project professionals tracking the sector, understanding this bifurcation is the defining task of 2026.


The Margin Squeeze: A Structural Problem, Not a Temporary Blip

The US construction industry is confronting its third major margin squeeze in the past decade, as material and labour costs continue to rise faster than bid prices, placing renewed pressure on contractor profitability.

The numbers are stark. Material prices are over 5% higher than a year ago, while bid prices have increased by roughly 1%.

Approximately 70% of a typical project’s total expenses are increasing substantially faster than bid prices.

This is not a new cycle — it echoes painful episodes from 2018 and 2021–22. But what makes 2026 different is the layering of pressures.

Since early 2020, construction input prices have increased more than 43%, with fabricated structural metal products rising over 63% during that period.

For contractors locked into fixed-price contracts, the arithmetic is unforgiving. Margins that looked acceptable at bid stage are being eroded by the time shovels hit the ground.


Tariffs: The Wildcard That Will Not Go Away

Just when the industry hoped for regulatory relief, the tariff landscape became more complex.

In a landmark ruling on February 20, 2026, the US Supreme Court struck down IEEPA-based emergency tariffs.

However, President Trump swiftly imposed a new 10% global import surcharge under Section 122 of the Trade Act of 1974, effective February 24 and valid for up to 150 days — with plans to raise it to the statutory maximum of 15%.

Critically for the construction sector, the court ruling offered limited comfort. Section 232 tariffs on steel and aluminium remain firmly in place, with aluminium prices up 30.5% and steel prices up 12% year-over-year.

The cumulative tariff burden is significant. Steel and aluminium now face 50% tariffs on all imports into the United States.

Copper carries a 50% tariff on semi-finished and intensive derivatives. Softwood lumber faces a 10% baseline with certain derivatives at 25%. Reciprocal tariffs on most countries range from 15–40%.

On an annualised basis, nonresidential construction input costs surged at 7.1% to open 2026, with most of January’s monthly rise traceable to tariff-induced increases in copper wire, cable, iron, steel, and industrial controls equipment.

The practical implications for project teams are significant. Tariffs on steel, aluminium, and copper are now fully embedded in pricing, with some categories seeing 20–30% gains.

Industry guidance now recommends locking prices early on long-lead items and including explicit escalation clauses in contracts, especially for metals and electrical.


The Infrastructure Winners: Data Centres, Utilities, and Grid Work

While traditional construction battles cost compression, a tier of infrastructure-focused engineering stocks is outperforming the broader market decisively.

EMCOR Group (NYSE: EME) remains the headline performer. Shares have gained 44.6% year-to-date, outpacing the heavy construction industry’s 41.6% growth. The driver is a combination of data centre exposure, healthcare construction, and mission-critical mechanical and electrical work — sectors where demand is structural rather than cyclical.

Quanta Services (NYSE: PWR) is arguably the most compelling long-term story in the sector.

The company reported a record backlog of $39.2 billion in Q3 2025, up from $33.96 billion a year earlier, reflecting strong visibility across generation, battery storage, transmission, and underground projects.

Consensus estimates point to 11% revenue growth and 16.9% earnings-per-share growth for 2026, with the EPS estimate revised upward to $12.38.

Sterling Infrastructure (NASDAQ: STRL) has quietly become one of the most remarkable transformation stories in the entire construction universe.

Once a struggling regional highway contractor, Sterling has reinvented itself as a mission-critical partner for hyperscale data centre development, posting a 1,700% return over the last five years as of March 13, 2026.

Its e-infrastructure segment — site preparation and civil work for data centres and AI facilities — is the engine powering its growth, with the stock trading at a forward price-to-earnings of roughly 25x.

The common thread across these winners? Exposure to the data centre construction boom. Data centre construction spending has surged fivefold in two years, with year-to-date starts through November 2025 hitting $53.7 billion — up 138.6% from the same period a year earlier.


Residential Construction: Caught in the Crossfire

Residential builders face the most acute tariff pressure of any construction sub-sector.

Current tariffs are projected to add roughly $30 billion to the costs of investment in residential structures, with approximately 90% of those costs falling on new home construction, including apartments.

This is particularly troubling given the backdrop. The US is estimated to be short between 3.7 and 4.9 million housing units relative to long-run demand — and the very materials needed to close that gap are precisely those facing the steepest import duties.

For housebuilder stocks, this creates a difficult outlook. Cost pass-through to buyers is constrained by affordability pressures, while input costs remain elevated. Margins are being compressed from both ends simultaneously.


Labour: The Slow-Burning Crisis

Beyond tariffs, labour shortages represent an equally serious structural headwind — one that does not attract the same headlines but is equally damaging to project economics.

Approximately 439,000 additional workers were needed in 2025, with nearly 500,000 required in 2026 to meet projected demand.

About 94% of contractors report difficulty filling open positions. Nearly 40% of skilled construction workers are over age 45, accelerating retirement risk and institutional knowledge loss.

Supply-side wage pressures are worsening as unauthorised workers are removed from the US labour force, further tightening an already constrained market. Specialty contractor wages are increasing even faster than industry averages.

For listed companies, this dynamic favours those with scale, established training pipelines, and technology adoption — a further competitive advantage for the larger engineering and infrastructure firms over smaller regional contractors.


What to Watch This Week

  • Caterpillar (NYSE: CAT) reports earnings on April 23 — but analyst debate around its $2.6 billion projected tariff cost exposure is already active. Any commentary on equipment demand from infrastructure clients will be a key read-through for the sector.
  • Tariff policy developments remain the primary macro wildcard. The 150-day Section 122 surcharge expires in late July 2026, and any signals from Washington about extension or escalation to 15% will move materials-exposed stocks.
  • Contract language evolution is worth tracking for CCE professionals — escalation clauses are now becoming standard practice in commercial construction agreements, shifting tariff risk from contractor to owner in new project negotiations.

CCE Verdict

The construction sector in 2026 is not a monolith. Infrastructure and digital economy-linked engineering firms — led by EMCOR, Quanta, and Sterling Infrastructure — are delivering outsized returns by positioning themselves at the intersection of electrification, data centre growth, and grid modernisation.

Traditional contractors, residential builders, and materials-intensive firms face a more challenging operating environment, where tariffs, labour scarcity, and margin compression are structural rather than temporary features.

For civil and construction engineering professionals, the investment lesson mirrors the operational one: specialisation, technology adoption, and exposure to long-duration infrastructure programmes are the differentiators that will define the sector’s winners through the rest of this decade.
