| Sector adoption velocity | claude-haiku-4-5-20251001 | 1/5 | Construction and structural steel work remain low-digitization, physical sectors where established workflows and human expertise dominate. Adoption of AI for blueprint reading is minimal; most firms lack the infrastructure and digital maturity to integrate such tools into daily operations. |
| Sector adoption velocity | claude-sonnet-5 | 2/5 | Construction is a historically slow-adopting, low-digitization sector; AI tools for take-offs and plan reading are in early pilot stages rather than widespread production use among iron/steel crews. |
| Augmentation potential | claude-haiku-4-5-20251001 | 3/5 | AI-assisted document parsing and material extraction could help workers by highlighting candidate quantities and locations for verification, reducing manual searching. However, the task's precision requirements and reliance on human judgment mean augmentation is modest—the worker still bears full responsibility for accuracy. |
| Augmentation potential | claude-sonnet-5 | 3/5 | AI can assist by digitizing blueprints, flagging quantities, and cross-referencing specs, providing useful support to workers but requiring human confirmation for accuracy and site-specific judgment. |
| Task automatability | claude-haiku-4-5-20251001 | 2/5 | While AI can extract text from blueprints and match it to specifications using OCR and document parsing, the task requires spatial reasoning, error detection, and cross-referencing that often demands human judgment. Current systems struggle with ambiguous or poorly scanned technical drawings and cannot reliably identify all material requirements without significant human verification. |
| Task automatability | claude-sonnet-5 | 2/5 | AI vision-language models can extract quantities and locations from blueprints in structured cases, but construction-grade blueprint interpretation with real-world ambiguity and take-off accuracy still requires human verification, so end-to-end automation with equal quality is not yet reliable enough to hit the 50% threshold broadly. |
| Adoption barriers | claude-haiku-4-5-20251001 | 4/5 | Safety-critical construction work requires licensed engineers to certify material specifications and site safety; AI output cannot legally replace human sign-off. Liability asymmetry is severe: errors in material quantity lead to structural failure and worker safety risks, creating strong organizational and regulatory friction against full automation. |
| Adoption barriers | claude-sonnet-5 | 2/5 | No licensing requirement specifically for reading blueprints, but liability for structural errors and reliance on field verification create moderate organizational friction against fully trusting automated interpretation. |
| Cost vs. human wage | claude-haiku-4-5-20251001 | 2/5 | Integration of AI document parsing requires upfront setup, model tuning for industry-specific formats, and ongoing human verification. Combined with inference costs and error remediation, the total cost approaches or exceeds the loaded wage of a skilled structural worker reading blueprints. |
| Cost vs. human wage | claude-sonnet-5 | 3/5 | Software-based blueprint analysis is cheap per document, but integration, verification, and correction by skilled workers keeps the effective cost roughly comparable to human review for this specific skilled trade context. |
| Technical feasibility today | claude-haiku-4-5-20251001 | 2/5 | Some OCR and CAD document parsing tools exist, but they have high error rates on complex or handwritten annotations, and few are deployed in production workflows for steel work. Most structural firms still rely on human inspectors to read blueprints reliably; AI tools remain experimental and require heavy oversight. |
| Technical feasibility today | claude-sonnet-5 | 2/5 | Some construction-tech products (e.g., takeoff software with AI assistance) exist for quantity estimation, but they are narrow, error-prone on complex structural drawings, and not widely deployed as autonomous readers for on-site iron/steel work decisions. |

| Sector adoption velocity | claude-haiku-4-5-20251001 | 2/5 | The construction and fabrication sectors have relatively low digital maturity and slow automation adoption. While some large shops use CNC and robotic welding, the majority of small-to-medium fabrication remains labor-intensive, and displacement by AI-driven automation is minimal and slow. |
| Sector adoption velocity | claude-sonnet-5 | 2/5 | Construction and metal fabrication are traditionally slow-adopting, physical-labor-intensive sectors with limited AI/robotics penetration compared to information-based industries. |
| Augmentation potential | claude-haiku-4-5-20251001 | 2/5 | Current AI can support planning and documentation (blueprint visualization, cutting lists), but offers limited real-time assistance during hands-on fabrication.

| Task automatability | claude-haiku-4-5-20251001 | 2/5 | While some design-to-CAM steps can be partially automated, the core fabrication work—cutting, bending, welding, and assembly of steel frames—requires physical manipulation, real-time quality judgment, and adaptation to material variations that current AI cannot perform end-to-end. The task is primarily physical and hands-on, limiting AI's role to planning or documentation support. |
| Task automatability | claude-sonnet-5 | 1/5 | Fabricating structural steel parts requires physical cutting, welding, and forming of heavy materials that current AI systems cannot perform without robotic hardware, and even automated fabrication lines require extensive human setup and oversight. |
| Adoption barriers | claude-haiku-4-5-20251001 | 4/5 | Structural steel fabrication has strong barriers: safety regulations mandate qualified workers, on-site conditions demand judgment and adaptability, quality and load-bearing liability rest on human expertise, and the physical presence and skill of licensed ironworkers are integral to the process. |
| Adoption barriers | claude-sonnet-5 | 3/5 | While no license is strictly required to operate fabrication equipment, structural components must meet building codes and engineering specifications, creating quality assurance and liability pressures that favor experienced human fabricators and inspectors. |
| Cost vs. human wage | claude-haiku-4-5-20251001 | 2/5 | Current AI-assisted or robotic fabrication systems (CNC, welding robots) still require significant upfront capital, ongoing maintenance, and human oversight; the all-in cost per frame fabricated remains comparable to or higher than employing skilled steel workers, especially for custom or small-batch work. |
| Cost vs. human wage | claude-sonnet-5 | 2/5 | Robotic fabrication equipment has high upfront capital costs and requires programming, maintenance, and human oversight, making it costlier than human labor for many small-to-mid volume or custom fabrication jobs. |
| Technical feasibility today | claude-haiku-4-5-20251001 | 2/5 | No deployed AI system can autonomously fabricate structural steel members according to blueprints at production scale. CNC cutting and some robotic welding exist in narrow contexts, but full frame fabrication—interpreting blueprints, material handling, tolerance checking, and multi-step assembly—remains predominantly manual and requires skilled workers on-site. |
| Technical feasibility today | claude-sonnet-5 | 2/5 | CNC plasma cutters and robotic welding exist in some fabrication shops, but these are narrow, capital-intensive automation solutions rather than general AI products, and most structural steel fabrication still relies heavily on skilled human labor. |

| Sector adoption velocity | claude-haiku-4-5-20251001 | 2/5 | Adoption is limited to large, standardized fabrication shops with high-volume, repetitive work. Field structural ironworkers and small shops have slow AI/robot adoption due to capital cost, regulatory friction, and the need for human judgment on each unique structure. |
| Sector adoption velocity | claude-sonnet-5 | 1/5 | Construction and structural fabrication trades are among the slowest sectors to adopt AI/robotics due to physical variability, safety regulation, and low digitization of fieldwork. |
| Augmentation potential | claude-haiku-4-5-20251001 | 2/5 | AI vision or planning tools can assist in layout and sequencing, but the tactile, safety-critical nature of wielding torches and welding equipment limits meaningful real-time augmentation. Human skill and judgment remain dominant, with limited AI co-working today. |
| Augmentation potential | claude-sonnet-5 | 2/5 | AI can assist with planning, layout software, or fixed-shop robotic pre-fabrication, but offers little direct in-the-moment assistance to a worker manually cutting or welding on site. |
| Task automatability | claude-haiku-4-5-20251001 | 2/5 | While AI can plan cutting/bending sequences via vision systems, the physical precision, safety-critical torch/welding control, and real-time adaptation to material variation require embodied robotics that lack reliable deployment at scale today. End-to-end automation with 50% time savings is not demonstrated in production. |
| Task automatability | claude-sonnet-5 | 1/5 | This is a physical fabrication task requiring manual dexterity, mobile positioning of heavy materials, and adaptive judgment on-site; no current AI/robotic system can perform this end-to-end at equal quality with major time savings. |
| Adoption barriers | claude-haiku-4-5-20251001 | 4/5 | Steel work is heavily regulated by OSHA and industry codes; welds must pass NDT inspection and be signed off by certified welders. Legal liability for structural failures creates a hard requirement that a licensed human perform or certify the work. |
| Adoption barriers | claude-sonnet-5 | 4/5 | Structural welding often requires certified welders per safety codes and inspection sign-off, creating strong regulatory and liability barriers to automation, though not an absolute licensing mandate for every cut/bend. |
| Cost vs. human wage | claude-haiku-4-5-20251001 | 2/5 | Specialized welding robots and cutting equipment are capital-intensive and require significant setup, integration, and maintenance. For one-off or complex structural pieces, human labor remains cheaper than deploying flexible automated systems. |
| Cost vs. human wage | claude-sonnet-5 | 1/5 | Robotic welding/cutting rigs for unstructured field environments are far more expensive to deploy and maintain than a skilled worker's wage for this task, especially given portability needs. |
| Technical feasibility today | claude-haiku-4-5-20251001 | 2/5 | Robotic welding and cutting exist in controlled factory settings, but generalist field deployment (varying materials, positions, safety constraints) remains immature. Production systems handle narrow, repetitive cases; they do not reliably handle the full range of field structural work conditions. |

AI could further assist by logging measurements, flagging anomalies, or generating reports, but the core verification judgment remains human-centered. |
| Augmentation potential | claude-sonnet-5 | 3/5 | Digital levels, laser equipment with smart sensors, and BIM-integrated measurement tools can assist workers by providing faster, more precise readings, though the core verification remains human-performed. |
| Task automatability | claude-haiku-4-5-20251001 | 2/5 | While laser equipment and digital levels can generate alignment data automatically, end-to-end verification requires interpreting spatial relationships, making judgment calls on acceptable tolerances, and coordinating readings across multiple members on an active worksite. AI cannot yet fully replace the on-site judgment and decision-making needed to verify alignment meets structural specifications. |
| Task automatability | claude-sonnet-5 | 1/5 | This requires physical presence at height, manual instrument setup, and hands-on measurement of physical steel structures; no AI system can perform this physically embodied verification task. |
| Adoption barriers | claude-haiku-4-5-20251001 | 4/5 | Structural steel work has strong regulatory oversight and building codes specify inspection and sign-off procedures. Liability is high if misalignment goes undetected; the work often requires licensed or certified personnel to verify and approve findings, creating legal and contractual barriers to full automation. |

| Cost vs. human wage | claude-haiku-4-5-20251001 | 1/5 | Current robotic systems capable of heavy construction tasks are extremely expensive and require custom engineering, making them far more costly than the loaded wage of a skilled structural steel worker for this specific task. |
| Cost vs. human wage | claude-sonnet-5 | 1/5 | There is no AI/robotic substitute performing this physical task, so cost comparison favors the human worker by default; deploying any robotic alternative would be far more expensive than current ironworker labor. |
| Technical feasibility today | claude-haiku-4-5-20251001 | 1/5 | No deployed AI system can ride on girders, manipulate heavy steel members in three-dimensional space, or guide rope placement on active construction sites. This remains firmly in the domain of human workers with specialized training. |
| Technical feasibility today | claude-sonnet-5 | 1/5 | No deployed products or robotic systems ride structural steel or guide it into place with ropes on construction sites; this remains entirely manual, skilled human work. |

Dismantle structures or equipment.
3| Dimension | Model | Rating | Rationale |
|---|---|---|---|
| Sector adoption velocity | claude-haiku-4-5-20251001 | 1/5 | The construction and skilled trades sectors show lagging AI adoption; dismantling work is site-specific, physically embedded, and subject to heavy regulation that slows mechanization compared to information-sector tasks. |
| Sector adoption velocity | claude-sonnet-5 | 1/5 | Construction and heavy industrial trades are among the least digitized sectors with minimal AI/robotic adoption for physical dismantling tasks in production settings. |
| Augmentation potential | claude-haiku-4-5-20251001 | 2/5 | AI could assist with pre-dismantling planning (structural analysis, hazard mapping) or documentation, but the core manual execution task offers limited scope for assistive AI while a human performs the dismantling. |
| Augmentation potential | claude-sonnet-5 | 2/5 | AI can assist with planning, structural analysis, or hazard identification via software tools, but offers little direct in-task assistance during the physical act of dismantling. |
| Task automatability | claude-haiku-4-5-20251001 | 1/5 | Dismantling structures or equipment requires physical manipulation in unstructured, hazardous environments with complex decision-making about load-bearing integrity and safety protocols. Current AI systems lack the embodied dexterity, real-time environmental adaptation, and safety certification needed for end-to-end execution. |
| Task automatability | claude-sonnet-5 | 1/5 | Dismantling structures or equipment requires physical strength, dexterity, situational judgment, and mobility in hazardous environments that current AI systems cannot perform end-to-end; this is a physical manual task, not a cognitive/digital one. |
| Adoption barriers | claude-haiku-4-5-20251001 | 5/5 | Strict OSHA and industry safety regulations require licensed, competent personnel to perform dismantling work; liability for injuries or structural failure is high; and human presence on-site is legally mandated for workplace safety and sign-off. |
| Adoption barriers | claude-sonnet-5 | 4/5 | Structural dismantling involves major safety regulation (OSHA), site-specific engineering judgment, and liability for structural failure or injury, creating strong barriers to full automation even if technology existed. |
| Cost vs. human wage | claude-haiku-4-5-20251001 | 1/5 | The cost of robotic systems capable of performing safe dismantling, plus integration, maintenance, and safety oversight, far exceeds the loaded wage of a skilled structural worker who can be deployed flexibly across varied projects. |
| Cost vs. human wage | claude-sonnet-5 | 1/5 | There is no viable AI-driven substitute performing this physical task, so any hypothetical robotic system would be far more costly than a human ironworker given current robotics costs and lack of maturity. |
| Technical feasibility today | claude-haiku-4-5-20251001 | 1/5 | No deployed AI products reliably perform structural dismantling at scale; this remains a skilled manual trade requiring human judgment, physical presence, and real-time hazard response that no production system can independently handle. |
| Technical feasibility today | claude-sonnet-5 | 1/5 | No deployed product autonomously dismantles structural steel or equipment; robotics for demolition/disassembly remain research or highly narrow pilot stage, not reliable production systems for this varied task. |

How to read this
A high substitution score does not mean this job disappears — it means a large share of its current tasks face replacement pressure, so the mix of tasks is likely to change. High augmentation alongside substitution typically means the occupation reorganizes around the protected tasks. Wide confidence intervals mean the rater panel disagreed: treat those scores as open questions, not verdicts.
What would change this score
New model capabilities (automatability, feasibility), falling inference costs (cost ratio), regulation and licensing shifts (barriers), and measured sector adoption (velocity) all re-enter at every index release. Each release is recomputed, versioned and kept queryable — scores are claims with a date on them, not permanent labels.
