Koranit Construction Co.,Ltd

What Koranit Construction Co.,Ltd does

Koranit Construction Co., Ltd. (บริษัท กรณิศ ก่อสร้าง จำกัด) is a privately-held Thai general contractor founded in 2001 and headquartered in Bangkapi, Bangkok. The company provides structural construction, architectural finishing, external works, and building-systems installation (electrical, mechanical, M&E) for residential, commercial, industrial, and institutional projects — including high-rise and low-rise condominiums, factories, showrooms, offices, hospitals, hotel/resort facilities, and civil engineering works such as those at Wat Phra Dhammakaya. Its customer base spans major Thai property developers (Sansiri via SIRI-MF THREE, Pruksa, S ONE RIVER) and industrial operators (F&F Food, Thaveevong Agriculture, Iberry Homemade, Pacific Cold Storage, Packfood), as well as Thailand's flagship One Bangkok development, where the company is one of six primary contractors.

The business operates on a fixed-price, project-based construction contract model, with revenue recognized on a percentage-of-completion basis. Pricing is per-project and publicly disclosed on the company website (contract values exclude 7% VAT). Projects are acquired through direct bids and enterprise client relationships executed via a direct field-sales go-to-market motion, with no third-party intermediaries or distribution channels. The active-portfolio contract value total is approximately ฿3.25B across 5 current projects (XELF, AURA, PACA, FFIW, TVA2) and ฿5.86B across all listed projects. The company holds ISO 9001 certification from Bureau Veritas (2025) and won the Outstanding Contractor Award for Cleanliness Management from ONE BANGKOK in September 2023.

Despite a contract portfolio on the order of multiple billions of Thai Baht, the company operates with a lean core of approximately 10 direct employees, indicating reliance on a heavily subcontracted workforce for actual construction labor. The firm is privately held, with no disclosed parent company, institutional investors, or venture capital backing, and no public listing. Its primary differentiators are sustained enterprise-client trust (evidenced by the One Bangkok appointment and Sansiri anchor contract), diversified execution capability across project types, and a recurring stream of mid- to large-scale contract wins through 2025-2026.
