Kayson

What Kayson does

Kayson Inc. is a publicly listed Iranian EPC (Engineering, Procurement, Construction) and Design-and-Build contractor founded in 1973 and headquartered in Tehran. The group operates through six core divisions — Oil, Gas & Industry; Housing & Buildings; Civil; Railway Transportation Systems; Water & Environment; and Power & Power Plant — and an ecosystem of more than 18 wholly-owned subsidiaries that handle specialized execution (water and environment, railway development, power plants, petro-industry, oil and gas E&P via KOGC, marine and geotechnical engineering, polymer-concrete pipe manufacturing, IT, security, mining, and trading).

Technically, Kayson combines a hybrid matrix organizational structure with computerized network-based project planning, cost control, quality, HSE, and HR systems, backed by an ISO-certified machinery and equipment fleet. It claims several Iranian firsts: the design and build of Concrete Face Rockfill Dams (Siah Bishe, 1,000 MW pumped storage), domestic application of pipejacking and microtunneling for sewerage works, an E&P certification from the National Iranian Oil Company (NIOC, August 2017) for upstream oil and gas activity, and fast-track design-and-build delivery of Imam Khomeini International Airport Phase 1.

Commercially, Kayson generates revenue primarily through one-time fixed-price and lump-sum EPC project contracts, with pricing determined through competitive bidding on government tenders and direct negotiation. The go-to-market is enterprise field sales targeting Iranian ministries, municipalities, and regional water authorities alongside foreign governments in more than 10 countries including Venezuela, Oman, Belarus, Kyrgyzstan, India, Equatorial Guinea, Iraq and Cameroon. Award highlights include ENR Rank 99 in the Top 250 International Contractors, 11 consecutive years as Iran's Exemplary Exporter of Technical and Engineering Services, and Iran's Best Construction Work awards in 1997 for the Yadegar Imam Flyover and Afsarieh Interchange.

Broad incumbents

• Técnicas Reunidas: Madrid-listed international EPC contractor specializing in oil & gas refineries, petrochemicals, and power generation. Comparable to Kayson's Petro Industry and Power divisions and historically active in Iran refinery projects.
• SEPCO3 Electric Power Construction Corporation: Chinese state-owned EPC contractor ranked among ENR Top 100 International Contractors, with major hydropower and power-plant portfolio globally. Direct comparable to Kayson Power & Power Plant division and Siah Bishe-style pumped-storage work.

• Petrofac Limited: UK-listed global EPC and operations services provider focused on oil & gas, with major Middle East exposure. Closely comparable to Kayson's Oil, Gas & Industry division and KOGC's upstream ambitions, though at significantly larger scale and with broader international footprint.

Direct peers

• Khatam al-Anbiya Construction Headquarters: Iran's largest state-owned EPC contractor and IRGC-affiliated engineering conglomerate. Competes directly with Kayson on large government-tendered megaprojects across oil & gas, water, civil, and power sectors in Iran and regional markets.
• MAPNA Group: Iranian EPC conglomerate and Kayson's JV partner on the Qom Monorail project. Operates across power generation, rail, and oil & gas EPC with similar diversified-division structure, making it the closest direct peer within Iran.
