The 2026 AEC Outlook: From Connected Data to Agentic AI

AEC Trends to Watch in 2026
The Architecture, Engineering, and Construction (AEC) industry has long been a collection of "islands". That is, brilliant specialists working in silos, disconnected data, and manual hand-offs. But as we move into 2026, the narrative is shifting.
Success in 2026 is no longer defined by who has the newest digital tool, but by who can bridge the translation gap to connect data, automate delivery, and prove performance across the entire building lifecycle.
Here are some of the key trends Exelsiv sees driving that shift.
Agentic AI: Moving from “Assist” to “Act”
The RICS artificial intelligence in construction report from late 2025 shows AI is still early-stage for most AEC organisations: around 45% report no implementation and 34% are running pilots, even though 56% of investors planned to increase AI funding. Regular use of AI sits at just under 12% for specific processes, and scaling is rare (1.5% across multiple processes and <1% organisation-wide). Taken together, the numbers point to an “intent vs execution” gap, where enthusiasm and funding are rising faster than the operating model needed to deploy AI safely at scale.
However, respondents are optimistic about AI improving data-heavy and decision-heavy work, and RICS notes the sector could see adoption increase dramatically within the next 12 to 24 months. Furthermore, early adopters are already seeing tangible time returns: in one 2026 outlook survey by Bluebeam, nearly half of early AI adopters (46%) reported reclaiming 500–1,000 hours on tasks like scheduling, planning, and document analysis.
Exelsiv Take: The winners will treat AI like a delivery capability rather than a tool rollout, because the biggest constraints are still skills, integration, and data quality. In practice, that means standardising the workflows AI will sit inside (document control, cost flows, RFIs, approvals) and setting clear governance before scaling pilots.
Industrialised Construction & DfMA
Industrialised delivery (including modular/offsite and prefabrication) is increasingly framed as a response to productivity constraints and workforce challenges by shifting work into controlled manufacturing environments.
McKinsey reports modular construction can reduce schedules by 20–50%, supporting the case that programmatic, repeatable delivery is moving closer to the mainstream for the right building types and supply chains. Design for Manufacture and Assembly (DfMA) is the technical enabler: it tightens the link between design and fabrication/assembly logic so BIM can function as a production input, not just a coordination artifact.
Exelsiv Take: Industrialised construction only scales when the “model” becomes a controlled production asset, so model governance, tolerance strategy, and change control need to mature alongside factory capacity. The organisations that win here will build repeatable component standards and a realistic logistics/assembly plan early, rather than trying to “value-engineer modular” late in delivery.
Connected Data as a Strategic Differentiator
Many AEC organisations are still losing time to “data islands,” and industry commentary continues to highlight disconnected systems and hybrid workflows as a drag on project continuity.
The 2026 outlook survey by Bluebeam illustrates the gap: only 11% of organisations consider themselves fully digital from design to delivery, while many still use paper during the design and planning phases. Meanwhile, investment is increasing (84% plan to increase technology spend), but integration is now the limiting factor: 23% cite integration as their primary barrier, suggesting the next productivity gains are more likely to come from interoperability and workflow continuity than adding another standalone tool.
Exelsiv Take: Stop trying to “connect everything” at once. The fastest path is to pick a few “golden threads” (e.g. model ↔ documents ↔ cost ↔ programme), define the hand-offs and ownership, and integrate those end-to-end first, before then scaling the pattern.
Whole-Life Carbon & Circularity
Decarbonisation pressure is intensifying: in 2023, buildings and construction accounted for 32% of global energy demand and 34% of global CO₂ emissions, and the sector is described as not on pace for its decarbonisation goals, as cited by a The UN Global Status Report on building and construction. This same source quantifies the lifecycle split driving 2026 priorities: 9.8 gigatonnes of operational emissions (building use) and around 2.9 gigatonnes of embodied emissions (materials/construction). This is accelerating circular construction and retrofit thinking, as firms pursue scalable approaches (reuse, material efficiency, and better lifecycle data) to meet rising client and policy expectations for measurable performance.
How this intersects with the industry’s “AI acceleration” story is still emerging. RICS’ AI in Construction 2025 report suggests that the market is not yet strongly connecting AI to sustainability outcomes: respondents ranked AI’s potential impact on sustainability relatively low (21%), and only 8% expected AI’s most significant impact to be in low-carbon and circular construction over the next five years.
There’s also an uncomfortable reality that rarely gets airtime: AI itself can be resource-intensive. Research on “sustainable AI” highlights that AI workloads can have a meaningful energy footprint and also a water footprint, because data centres consume water for cooling (and AI’s footprint can also include indirect water impacts). For example, one widely cited estimate finds training GPT models in U.S. data centres could consume 5.4 million litres of water in total, including 700,000 litres of direct on-site water consumption.
Exelsiv Take: The near-term opportunity is practical: treat carbon like a managed project outcome by connecting design data, procurement/material data, and operations data so teams can quantify trade-offs earlier and track results consistently through delivery and into use. And if AI is part of the plan, it should be held to the same standard by prioritising use cases with measurable carbon benefit, and making the infrastructure footprint (energy and water) visible rather than assumed away.
The Bottom Line for 2026
The firms that thrive this year will be those that stop looking at projects as a series of tasks and start viewing them as integrated data systems. Whether it's scaled AI adoption, modular delivery, or lifecycle carbon accountability, the theme is clear: connection (between people, process, and data) is what turns tools into outcomes.
Exelsiv Insight
At Exelsiv, we believe the 2026 advantage will come from building “data-to-decision” delivery: connect your systems first, then automate repeatable workflows, and finally apply AI where governance and data quality can sustain it at scale.
