What Kim's United Investment Co., Ltd does

Kim Mex Construction & Investment Co., Ltd. (branded KIMMEX) is a Cambodia-based, privately held construction and engineering firm founded in 1999 by Okhna. TOUCH KIM and headquartered at #54, St.590, Sangkat Boeung Kok II, Khan Toul Kork, Phnom Penh. The company delivers four integrated service lines — Design & Build, Construction, Project Management, and Infrastructure Development — for government ministries, public institutions, universities, and healthcare clients across Cambodia. Its portfolio spans 150+ projects including 8- to 14-story office towers (e.g., the 9-story NEC building at 32,000 m², the 12-story GDCE-SHV customs facility, the 14-story NBFSA authority building, the 12-story NSPC building), smart campus facilities (RUPP Smart Building, 16,500 m²), utility infrastructure (Stung Treng water purification, EDC stadium, electricity facilities), and justice-sector projects. Disclosed individual contract values range from approximately $3.6M to $23.7M. KIMMEX employs 500+ staff and operates under ISO 9001:2015-certified quality management processes. Its technology stack is conventional civil engineering and project management, supplemented by stated process commitments (Zero-Incident Safety Policy, rigorous QA/QC, 98% on-time delivery) and, per company communications, an in-house hybrid construction material called TimberCrete-X ("liquid wood concrete") that received GAEC approval in 2025 for primary structural use in buildings exceeding 40 floors. Revenue is generated through fixed-price, project-based contracts secured primarily via direct engagement and competitive bidding with Cambodian government ministries and institutions — the company explicitly does not use resellers, distributors, or marketplace channels. The go-to-market motion is enterprise field sales targeting ministries, agencies, and educational institutions, with multi-year contract durations tied to project scope. The value proposition rests on 25+ years of operating history in Cambodia, established government relationships, and demonstrated capacity to deliver multi-million-dollar institutional projects on-time. Ownership remains concentrated with the founding family; no external funding rounds, private equity involvement, or public listing have been identified.
