South Korean construction firms and global startups are scaling AI from pilot projects to integrated platforms, driving a projected 24.7% annual growth in the construction AI market. The shift targets procurement, safety, and quality - the operational bottlenecks that cause billions in cost overruns on megaprojects like Hudson Yards and the Big Dig.
Korean contractors build enterprise AI platforms
Nearly half of the 157 companies listed in the Korea Proptech Forum 2026 member directory now run AI as a core business function, according to Chosun Ilbo. The forum's first dedicated 'AI Edition' maps 75 AI-enabled firms across development, construction, transactions, marketing, and asset management.
DL E&C presented its AI-driven innovation case at Palantir Technologies' APAC Summit Korea 2026 in April. The firm adopted Palantir's Foundry platform in 2022 and built a 'Flywheel ecosystem' connecting design, construction, and maintenance data. More than 87 years of accumulated records on costs, quality, safety, and design now feed live project planning meetings. Work instructions generated during construction automatically populate planning records, so past change orders and risk events surface when new projects are scoped.
GS Engineering & Construction developed an AI Defect Prevention Platform internally and integrated it into its quality management system. The platform analyzes defect types by process, visualizes cases in 3D, and supports multilingual job sites. GS E&C reported zero defect judgments in two consecutive reviews by South Korea's Ministry of Land, Infrastructure and Transport over the past year, Chosun Ilbo said.
Daewoo Engineering & Construction targeted a different risk: AI hallucination in contract and specification review. Its Baro-Dap AI is a vertical model trained only on internal contracts and specifications, answering solely from that document corpus. A companion tool, Baro-Letter AI, handles document drafting. By grounding the model in proprietary data, Daewoo addresses a reliability concern that has slowed enterprise adoption of generative AI in legal and compliance workflows.
Samsung C&T is collaborating with AWS on an AI agent for construction operations and has deployed an automated steel bolt-tightening robot for structural fastening at height. Hyundai Engineering & Construction operates a generative AI-based sales consultation service.
Supply chain failures drive cost overruns
Forbes contributor Sabbir Rangwala pointed to megaproject case studies including Hudson Yards, the Big Dig, and the Burj Khalifa as examples of cost and schedule overruns. Hudson Yards was affected by a shortage of steel and other materials tied to market demand, tariffs, and production constraints, contributing to billions in overruns.
The structural problem, as Forbes described, is that construction has not historically adopted design-for-manufacturing and design-for-reliability disciplines. Every project is effectively a one-off, making it harder to encode prior knowledge into future planning without AI-assisted tools. This is where AI for Operations can help teams surface supply chain risks earlier.
Krane, a startup founded in 2022 by CEO Eshan Jayamane, targets that gap. Jayamane, with a background in large-scale industrial and energy infrastructure, built Krane to provide a unified real-time platform managing submittals, lead times, purchase orders, and delivery schedules across thousands of suppliers. The company raised $9 million to expand these capabilities. Its platform surfaces supply chain risks during the design phase, when projects can still absorb changes without costly scope pivots.
Why this matters for operations teams
Evaluate vendor AI for hallucination controls. Daewoo's approach of grounding AI responses in internal documents is a practical model for procurement or legal teams considering AI for contract review. Ask vendors how their system handles out-of-corpus queries before deployment.
Assess whether your project data is structured enough to feed a platform. DL E&C's deployment draws on decades of cost, quality, safety, and design records. If your historical project data is siloed or unstructured, that prerequisite must be solved before AI can deliver feedback-loop value.
Build supply chain visibility into design-phase workflows. Krane's model targets the design stage, when lead-time and procurement constraints can still be designed around. Project managers running active procurements on large builds should evaluate real-time supply chain platforms before steel orders are placed.
Use the Korea Proptech Forum's AI Map as a competitive benchmark. With nearly half of 157 member firms running AI as a core function, the map signals where the industry baseline is moving and which functional gaps remain underserved. For teams tracking AI for Real Estate & Construction, this provides a practical reference point.
