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.
