The global construction industry faces an existential reckoning: without transformative change, the sector will fall $40 trillion short of infrastructure and housing needs by 2040. This isn’t merely a capacity problem—it’s a convergence of workforce collapse, climate mandates, technological resistance, and financial fragility that threatens to undermine the built environment’s ability to meet humanity’s most basic needs. The industry that employs 7% of the global workforce and represents 13% of world GDP must reinvent itself within a decade, or risk becoming the bottleneck that stalls economic development, climate action, and social stability worldwide.
Construction spending must grow from $13 trillion annually to $22 trillion by 2040—requiring the sector to nearly double its output while simultaneously decarbonizing, digitizing, and replacing a workforce where 41% will retire within six years. This analysis examines ten interconnected challenges that will define the industry through 2035, drawing on data from McKinsey, the World Economic Forum, government agencies, and industry associations to map the path forward.
A Workforce Crisis Decades in the Making
Construction faces the most severe labor shortage in its modern history, with 92% of U.S. firms reporting difficulty filling positions and the industry needing an additional 439,000 workers in 2025 alone. The UK requires 251,500 extra workers by 2028, while globally, construction demand will increase by $4.2 trillion over the next fifteen years against near-zero workforce growth in advanced economies.
Aging Workforce
The median U.S. construction worker is 42.5 years old, with 22% over age 55—a figure that has climbed from 11% in 2003.
Mass Retirement
The NCCER estimates that 41% of the pre-2020 U.S. construction workforce will retire by 2031, taking irreplaceable experiential knowledge.
Youth Gap
Only 10% of U.S. construction workers are under 25, compared to 13.6% across all sectors.
Perception Problem
57% of potential workers are deterred by the male-dominated image, while only one-third of Gen Z sees construction as addressing climate crisis.
The UK faces similar demographics, expecting to lose a quarter of its workforce within fifteen years. CIOB research reveals persistent perception problems: the industry is commonly described as “overly physical” and “dangerous.”
Encouraging Signs: Gen Z’s share of the construction workforce doubled from 6.4% to 14.1% between 2019 and 2023, driven partly by concerns about college debt and growing respect for skilled trades. Companies are responding with enhanced recruitment strategies, VR/AR training simulations, and improved work-life balance initiatives. The fundamental question is whether this nascent pipeline can scale fast enough to offset the coming retirement wave.
Productivity Stagnation Threatens Everything
The industry’s productivity crisis underlies every other challenge it faces. While the total economy achieved 50% productivity improvement from 2000 to 2022 and manufacturing achieved 90%, construction managed just 10%—and U.S. construction productivity is actually lower today than in 1968.
McKinsey’s August 2024 analysis reveals that construction became 1-3% more expensive annually on top of general inflation, with European construction costs rising 36% from 2015-2023 and U.S. nonresidential prices increasing 52% over the same period.
Margin Erosion
Return on invested capital has declined 0.5 percentage points globally from 2008-2023, limiting reinvestment capacity for technology and training.
The roots of this stagnation are structural:
- Fragmented industry structure prevents economies of scale, with millions of small firms competing on price rather than efficiency
- Low technology investment: construction historically spent less than 1% of revenue on IT—one-third of aerospace and automotive
- Project uniqueness resists standardization, with each build having different scope, context, team, and culture
- Tight labor markets directly reduce productivity: when the Gulf Coast labor market tightened, productivity fell over 40%
Decarbonization Mandates Arrive with Insufficient Preparation
The built environment accounts for 37% of global energy-related CO2 emissions, making construction central to any credible climate strategy. Yet only 5% of new buildings are currently zero-carbon-ready, against a target of 100% by 2030. The sector’s carbon footprint has doubled over thirty years and is projected to double again by 2050 under business-as-usual scenarios.
California CALGreen
Effective July 2024—became the first mandatory embodied carbon regulation in the United States, requiring whole-building life cycle assessments for commercial buildings over 100,000 square feet.
EU Buildings Directive
Mandates zero on-site fossil fuel emissions for all new buildings by 2030 and complete phase-out of fossil fuel boilers by 2040.
UK Future Homes Standard
Will require 75-80% CO2 reduction for new homes starting in 2025.
Embodied Carbon
Cement, brick, and metals account for over half of construction’s carbon footprint, with cement, iron, steel, and aluminum contributing approximately 15% of annual global emissions.
Industry Readiness Gap: According to One Click LCA, 87% of professionals cite lack of manufacturer Environmental Product Declarations as their primary barrier to measuring embodied carbon. No universal methodology exists for comparing embodied carbon across projects, and data gaps persist for many building components. The low-carbon construction materials market, valued at $238 billion in 2024, is projected to reach $588 billion by 2034—but scaling sustainable alternatives requires massive manufacturing investment that hasn’t materialized.
As buildings become more energy-efficient during operation, embodied carbon will grow from 25% to 50% of the sector’s total emissions.
Technology Promises Remain Unfulfilled
Despite $11.5 billion in late-stage venture capital flowing into construction technology from 2020-2022—more than triple the previous three years—the industry remains the second least digitized sector globally. The disconnect between investment and impact reveals deep structural barriers to technological transformation.
Building Information Modeling
After 35 years of development, BIM has reached only 60-70% adoption—compared to other technologies that achieve 90% adoption within 8-28 years. When properly implemented, BIM delivers a 45% reduction in rework costs.
Artificial Intelligence
Adoption among construction professionals jumped from under 10% in 2020 to over 40% in 2025. Yet 45% of construction firms have no AI implementation whatsoever, and only 1.5% use AI across multiple processes.
Modular Construction
Despite predictions of 30%+ market share by 2026, U.S. modular construction remains at approximately 5% of total activity. The $2 billion collapse of Katerra in 2021 exemplifies the challenges.
BIM barriers are well-documented: high initial costs, interoperability issues affecting 25% of users, skills shortages, and resistance to change. The gap between early adopters and laggards is widening, with implications for competitive positioning as the technology matures.
Successful modular companies have learned to focus on local regulatory expertise, smaller scale operations, and asset-light business models rather than attempting rapid nationwide expansion.
Supply Chains Face Permanent Restructuring
The pandemic exposed construction’s supply chain vulnerabilities, but the disruption has evolved rather than resolved. Material costs remain 38-40% above pre-pandemic levels, with steel rebar fluctuating from $425/ton in mid-2020 to $950/ton in March 2022, settling at $709/ton by late 2024.
Lead Time Transformation: Lead times have fundamentally shifted—electrical transformers now require 12-18 months delivery (compared to weeks pre-pandemic), switchgear up to 80 weeks, and HVAC equipment 45-50 weeks.
Tariff Impact
50% tariffs on steel and aluminum as of mid-2025 and Canadian lumber facing duties approaching 35%. The National Association of Home Builders estimates these tariffs add $10,900 to the cost of each new home.
Inflation Pressure
Input costs to U.S. construction firms rose 9.7% annualized in Q1 2025, reversing earlier stabilization trends.
Geopolitical Risk
Goods from Canada, Mexico, and China represent 41% of U.S. imports, with retaliatory tariffs now affecting $128 billion in trade.
Industry Fragility
The UK saw 4,690 construction firms enter insolvency in the twelve months to June 2024—representing 17% of all insolvencies and a 53% increase from 2020.
The September 2024 collapse of ISG, Britain’s sixth-largest contractor, illustrated the industry’s margin fragility: £2.18 billion in turnover yielded only £11.5 million in pre-tax profit, a margin of roughly 2%. Construction loan rates of 6-13% and fourteen consecutive quarters of tight credit conditions have further strained project viability.
Climate Resilience Becomes Mandatory
The insurance industry’s response to climate change is forcing construction adaptation faster than building codes. The U.S. experienced 27 billion-dollar disasters in 2024, causing $182.7 billion in damages—up from a frequency of one such disaster every four months in the 1980s to one every three weeks today. Cumulative environmental disaster costs over the preceding decade reached $1.2 trillion.
Insurance Market Fracturing
One in thirteen U.S. homeowners is now uninsured, representing $1.6 trillion in unprotected market value. Major insurers have exited California, Florida, and Louisiana, while premiums for covered properties continue rising—commercial property insurance increased 10.1% and auto liability 8-18% in early 2024.
Building codes are evolving in response, though implementation lags behind climate science:
- The 2024 International Codes introduced the first-ever tornado loading provisions for structural resilience
- The 2027 codes will add a new chapter specifically addressing climate-related weather threats
- California’s 2025 Wildland-Urban Interface Code establishes standards for defensible space and fire-resistant materials
- The National Institute of Building Sciences finds that every $1 invested in hazard mitigation saves $13 in avoided damage costs
However, code development operates on multi-year cycles while climate impacts accelerate annually. New York City projects seven heat waves per year with 57 days above 90°F by the 2050s, compared to two heat waves and 18 days historically. Ten percent of the U.S. population lives in areas now flooding more frequently than historical 500-year predictions.
Regulatory Complexity Escalates Across All Dimensions
Beyond climate and fire safety, construction faces a comprehensive expansion of regulatory requirements.
UK Building Safety Act 2022
The most significant reform in 40 years—created a Building Safety Regulator with authority over all higher-risk buildings, mandatory three-stage approval processes, and “Golden Thread” requirements for maintaining building information throughout the entire lifecycle.
Grenfell Response
The government accepted all 58 recommendations from the Grenfell Phase 2 inquiry, with remediation costs to date exceeding £2.3 billion and works on unsafe buildings expected to continue through 2035.
ESG Reporting
The EU’s Corporate Sustainability Reporting Directive requires disclosures starting 2025, with proposals for mandatory whole-life-cycle emissions disclosure for buildings effective 2027-2030.
Safety Standards
Construction’s fatality rate of 13.0 deaths per 100,000 workers in 2022 remains far above other industries, with 423 fatalities from falls alone.
The U.S. SEC adopted climate disclosure rules in March 2024, effective for year-end 2025 filings. Large construction firms must now report on entire supply chains, creating cascading compliance obligations for subcontractors. OSHA’s December 2024 rule requires PPE to “properly fit” all workers, and proposed heat hazard rules mandate water, shade, and rest breaks in high-heat environments.
The cumulative burden of these regulatory expansions is substantial, yet often disconnected. Building codes, fire safety rules, ESG requirements, safety standards, and accessibility updates each add complexity without systematic coordination, creating compliance challenges that disproportionately burden smaller firms with limited administrative capacity.
Housing and Infrastructure Deficits Reach Crisis Proportions
The scale of unmet construction demand dwarfs current capacity.
UN-Habitat data indicates 2.8 billion people worldwide lack adequate housing, representing approximately 40% of the global population. This figure is projected to reach 3 billion by 2030. Meeting current needs would require 96,000 new homes daily worldwide—a rate far beyond any historical achievement.
U.S. Housing Deficit
The U.S. faces a deficit of 6.5 million homes, while affordability has deteriorated to levels worse than the 2007-08 bubble.
UK Housing Gap
The UK must build 370,000 annually against recent delivery of approximately 82,000.
Infrastructure Spending
The McKinsey Global Institute estimates the world needs $3.7 trillion annually in economic infrastructure through 2035.
Global Gap
The cumulative global spending gap reaches $5.5 trillion through 2035.
The U.S. infrastructure report card reveals systemic deterioration. The American Society of Civil Engineers’ 2025 assessment grades national infrastructure at C-, with 42,000 structurally deficient bridges averaging 47 years of age against 50-year design lives. Roads receive a D grade, with 39-43% in poor or mediocre condition, costing drivers $621-1,400 annually in vehicle damage. Water infrastructure requires $625 billion over twenty years, with 9 million lead service lines still in use and 6 billion gallons of treated water lost daily through aging mains.
Megacity Growth Concentrates in Least-Prepared Regions
Urbanization will add 2.5 billion people to cities by 2050, with 90% of this growth occurring in Asia and Africa—regions with the least developed construction capacity and greatest infrastructure deficits. By 2030, 43 megacities will exist globally, with Delhi overtaking Tokyo as the world’s most populous city by 2028.
Fastest-Growing Cities Face Severe Challenges
- Kinshasa has doubled in population every five years since 1950
- Lagos, Dhaka, and Cairo are adding millions of residents without corresponding infrastructure expansion
- By 2100, all twenty largest megacities are expected to be in the developing world, with the majority in Africa
- Cities require $4.5-5.4 trillion annually for climate-resilient infrastructure, against current financing of just $831 billion
Urban green spaces have declined from 19.5% in 1990 to 13.9% in 2020, while informal settlements—most vulnerable to climate impacts—continue expanding. The affordable housing deficit for low-income urban households alone will reach 106 million units by 2025, requiring up to $16 trillion including land and construction costs.
Conclusion
An Industry at an Inflection Point
The construction industry stands at a critical juncture. The challenges documented here—a $40 trillion infrastructure gap, workforce collapse, productivity stagnation, climate mandates, and regulatory complexity—represent both existential threats and unprecedented opportunities.
The industry that employs 7% of the global workforce and represents 13% of world GDP must nearly double its output by 2040 while simultaneously decarbonizing, digitizing, and replacing a workforce where 41% will retire within six years.
Those organizations that recognize the interconnected nature of these pressures and invest accordingly will shape the built environment of the coming decades. Those that don’t may not survive to see it completed.
