We are proud to be working with clients on projects of all sizes, complexities, and sectors spanning across the Middle East and Central Asia. With projects, people, and offices in several countries, Tunnel Sadd Ariana has unmatched reach and expertise. Construction regulations and labor laws around the world vary greatly and we have worked successfully under some of the toughest circumstances. We have a proven record of working smoothly with government agencies and labor organizations. Major construction projects are complex undertakings, often involving several subcontractors and suppliers, thousands of workers, and millions of dollars in material, equipment, and services. Orchestrating such operations demands first-rate construction management, something Tunnel Sadd Ariana has provided for decades on projects big and small around Asia.
