The construction industry enters 2026 facing a rare challenge. FMI Corporation’s latest North American Engineering and Construction Outlook projects U.S. construction spending at just under $2.2 trillion for the year, essentially flat after a 1.4% contraction in 2025. This marks an unusual moment: for the first time in over 60 years, construction spending has declined outside a broader national recession. Understanding what drives this is essential for builders positioning for stability.

Understanding the 2026 Construction Spending Picture
FMI’s second-quarter outlook presents a market that is not collapsing but certainly not thriving. After stronger growth years in 2023 and early 2024, the pace has slowed markedly. The headline figure of $2.2 trillion in total spending masks wide variation beneath the surface. Several structural factors are constraining growth across the board.
Macroeconomic Headwinds Pressuring the Industry
The most immediate pressure comes from elevated interest rates. The Federal Reserve’s tightening cycle kept borrowing costs high through 2025 and into 2026, making project financing more expensive and slowing new developments. Tighter lending at commercial banks has compounded this, particularly for speculative commercial projects and smaller residential developments.
Geopolitical uncertainty adds another layer of complexity. Ongoing tensions in the Middle East, particularly the Iran conflict, have pushed oil prices higher. This ripples through the construction economy in multiple ways:
- Higher diesel prices increase equipment operating costs on every job site.
- Asphalt and petroleum-based materials become more expensive for paving and waterproofing.
- Freight and transportation costs rise, affecting material delivery pricing on both bulk commodities and specialty items.
- Elevated Treasury yields push mortgage rates higher, further depressing residential demand.
Together, these headwinds have created a market where selectivity is becoming the defining trait of successful contractors. According to FMI Chief Economist Brian Strawberry, firms that thrive in 2026 will be those that carefully choose where to deploy capital and labor.
The Historical Uniqueness of This Contraction
FMI notes this contraction is historically unusual. In every previous construction downturn over sixty years, the broader economy was also in recession. Today, the broader economy continues to grow while specific construction sectors contract. This divergence means builders must rely on sector-level data and regional demand patterns rather than broad macroeconomic indicators when planning strategy.
The Sector-Specific Recession: Eight of Nineteen Sectors in Decline
FMI’s outlook tracks 19 construction market segments. Eight of them are projected to decline in 2026, while the remaining eleven show flat or positive growth. This uneven distribution is the core story of the current market. Understanding which sectors are contracting and which are expanding is the first step in making informed bidding and investment decisions.

The Sectors Under the Most Pressure
Residential construction remains the primary drag on overall spending. Single-family homebuilding is down 2% year over year as affordability erodes. With 30-year mortgage rates at 6.22% in March 2026 and builder sentiment below break-even for 23 consecutive months, the residential outlook is subdued. Higher financing costs, elevated material prices, and persistent labor shortages all contribute.
Beyond residential, several commercial and industrial segments are also facing headwinds. Office construction outside of data center conversions remains weak. Retail and hospitality projects are proceeding cautiously. Manufacturing facility construction, which boomed during the post-COVID reshoring wave, is showing signs of plateauing as the most significant projects reach completion.
Understanding Segment-Level Divergence
The key insight from FMI’s analysis is that aggregate numbers tell only part of the story. A flat headline figure of $2.2 trillion conceals the fact that some segments are growing rapidly while others are shrinking just as quickly. The table below summarizes the projected performance across major construction segments for 2026.
| Construction Segment | Projected 2026 Change | Primary Driver |
|---|---|---|
| Water Supply | +5% | PFAS compliance, WIFIA financing, industrial demand |
| Sewage and Waste Disposal | +8% | Federal funding, EPA mandates, data center demand |
| Power Generation and Transmission | +14% (by 2028) | Grid modernization, renewable energy, data center load |
| Data Centers (in Office segment) | +6% | AI infrastructure, cloud computing demand |
| Highway and Street | Flat to modest | IIJA funding (pending reauthorization) |
| Single-Family Residential | -2% | High mortgage rates, affordability constraints |
| Manufacturing | Flat to declining | Reshoring wave plateau, project completions |
| Retail and Hospitality | Modest decline | Cautious lending, shifting consumer habits |
Bright Spots in a Flat Market: Infrastructure, Data Centers, and Power
While eight segments contract, several areas are delivering strong and sustainable growth. These bright spots share common characteristics: long-term demand drivers, federal or regulatory support, and relative insulation from interest rate sensitivity. Builders with capacity in these segments are well positioned for 2026 and beyond. For teams working on transportation-adjacent projects, Surveying New Railway Line Construction offers practical guidance on one of the infrastructure subsectors benefiting from sustained investment.
Water Infrastructure: The Top Nonbuilding Performer
Water infrastructure leads all nonbuilding segments in growth. Sewage and waste disposal spending is projected to rise 8%, while water supply construction grows at 5%. Three structural factors drive this performance:
- WIFIA (Water Infrastructure Finance and Innovation Act) financing provides low-cost federal loans that reduce the burden on local utilities and municipalities, enabling projects that might otherwise stall due to budget constraints.
- PFAS compliance mandates are accelerating investment in water treatment facilities nationwide as EPA regulations require utilities to remove emerging contaminants from drinking water supplies.
- Industrial demand from data centers and advanced manufacturing facilities requires substantial water infrastructure for cooling systems and process water, creating a secondary demand driver beyond traditional municipal needs.
These factors create a multi-year runway for water infrastructure spending that is largely independent of interest rate movements or broader economic cycles.
Data Centers Reshaping the Office and Power Sectors
Data center construction is perhaps the most striking growth story in the 2026 outlook. Office construction as a whole is showing a 6% increase, but this figure is almost entirely attributable to data center projects. Data centers will account for over half of all private office construction spending in 2026, fundamentally reshaping what the “office” category means in construction statistics. The surge is driven by artificial intelligence infrastructure, cloud computing expansion, and enterprise digital transformation.
This boom has spillover effects into the power sector. Data centers are energy-intensive, driving demand for power generation and transmission infrastructure. FMI projects power construction accelerating to 14% growth by 2028 as utilities race to build capacity for these facilities alongside grid modernization and renewable energy integration.
The Policy Wildcard: IIJA Reauthorization
Federal infrastructure policy introduces significant uncertainty into the 2026-2027 outlook. The surface transportation authorization under the Infrastructure Investment and Jobs Act expires September 30, 2026. Without reauthorization, highway and transit funding reverts to pre-IIJA levels, a substantial reduction. Contractors in highway, bridge, and transit construction should monitor this closely, as it will affect project availability and bid volume in 2027 and beyond.
Strategic Moves for Contractors in an Uneven Growth Environment
Given the sector-specific nature of the 2026 market, contractors need targeted strategies rather than broad-brush approaches. The firms that perform best this year will be those that align their capabilities with expanding segments while managing exposure to declining ones. For builders looking to refine their technical approach in stable categories like power and water, Flat Slab Construction and Design provides relevant structural engineering insights applicable to industrial and infrastructure projects.
Diversify into Infrastructure and Institutional Work
Contractors who have historically focused on residential or commercial work should evaluate the barriers to entry in water, wastewater, power, and transportation infrastructure. While these sectors often require different bonding capacity, safety certifications, and project management expertise, they offer revenue stability that the private sector cannot match. Key steps include:
- Pursue federal and state prequalification for public works projects in water and transportation.
- Develop or acquire specialized expertise in underground utility work, concrete water infrastructure, or electrical substation construction.
- Build relationships with engineering firms that serve municipal and utility clients, as design-build and CMAR delivery methods dominate public infrastructure.
- Invest in workforce training programs that produce certified operators and technicians for water and power facilities, where skilled labor is especially scarce.
Position for the Data Center Wave
Data center construction demands specific capabilities that command premium pricing. Builders with experience in raised access floors, precision cooling, high-density electrical distribution, and strict vibration standards will find strong demand. Development is concentrated in Northern Virginia, the Midwest, and the Sun Belt, but subcontractor opportunities exist nationwide as the data center supply chain expands.
Manage Cost Exposure in a Volatile Material Market
The Iran conflict and broader geopolitical tensions have created upward pressure on petroleum-based materials. Contractors should take several steps to protect margins:
- Include price escalation clauses in bids for projects lasting more than six months, particularly for asphalt, diesel, and chemical-intensive work.
- Lock in material prices with suppliers where possible, especially for large-volume purchases of rebar, concrete, and structural steel.
- Build contingency buffers of 5-10% into bids on fixed-price contracts to absorb material cost volatility.
- Monitor diesel futures and fuel surcharge mechanisms for equipment-heavy operations.
Invest in Selective Bidding and Market Intelligence
In a flat market with declining sectors, every bid matters more. Contractors should invest in market intelligence to identify which segments, regions, and project types offer the best risk-adjusted opportunity. This means tracking federal funding allocations, state DOT capital programs, utility capital expenditure plans, and private sector announcements from data center operators and manufacturers. The firms that bid smartly on the right projects will outperform those that chase volume across all segments.
Key Takeaways for 2026 Planning
- Total construction spending is flat at $2.2 trillion, but eight of 19 sectors are declining. Know which ones you serve.
- Water infrastructure (+5 to +8%) and data centers (+6% in office segment) are the strongest growth areas.
- Power construction is building toward 14% growth by 2028, driven by grid modernization and data center loads.
- IIJA reauthorization in September 2026 is the single biggest policy event to watch for infrastructure contractors.
- Material cost volatility from geopolitical tensions requires escalation clauses and contingency buffers on fixed-price work.
- Builder sentiment in residential has been below break-even for 23 months, and no rapid recovery is expected.
The 2026 construction market demands a more analytical approach than the growth years of 2023 and 2024. With a sector-specific recession creating winners and losers across the industry, builders who invest in market intelligence, diversify into infrastructure and data center work, and manage material cost risk will navigate the flat spending environment more successfully. The opportunity lies not in the aggregate but in the segments that continue growing even as the broader industry treads water.
